NAME

       containers.conf  - The container engine configuration file specifies default configuration
       options and command-line flags for container engines.

DESCRIPTION

       Container engines like Podman & Buildah read containers.conf file, if it exists and modify
       the  defaults  for running containers on the host. containers.conf uses a TOML format that
       can be easily modified and versioned.

       Container     engines     read     the      /usr/share/containers/containers.conf      and
       /etc/containers/containers.conf, and /etc/containers/containers.conf.d/.conf files if they
       exist.     When     running      in      rootless      mode,      they      also      read
       $HOME/.config/containers/containers.conf                                               and
       $HOME/.config/containers/containers.conf.d/.conf files.

       Fields specified in containers conf override the default options, as well  as  options  in
       previously read containers.conf files.

       Config  files  in the .d directories, are added in alpha numeric sorted order and must end
       in .conf.

       Not all options are supported in all container engines.

       Note container engines also use other configuration files for configuring the environment.

              • storage.conf for configuration of container and images storage.

              • registries.conf for definition of container registires to search  while  pulling.
                container images.

              • policy.conf for controlling which images can be pulled to the system.

FORMAT

       The  TOML  format  ⟨https://github.com/toml-lang/toml⟩  is  used  as  the  encoding of the
       configuration file.  Every option is nested under its table. No bare options are used. The
       format of TOML can be simplified to:

              [table1]
              option = value

              [table2]
              option = value

              [table3]
              option = value

              [table3.subtable1]
              option = value

CONTAINERS TABLE

       The containers table contains settings to configure and manage the OCI runtime.

       annotations  =  []  List of annotations. Specified as "key=value" pairs to be added to all
       containers.

       Example: "run.oci.keep_original_groups=1"

       apparmor_profile="container-default"

       Used to change the name of the default AppArmor profile of container engines.  The default
       profile name is "container-default".

       base_hosts_file=""

       The  hosts  entries  from the base hosts file are added to the containers hosts file. This
       must be either an absolute path or as special values "image" which  uses  the  hosts  file
       from  the container image or "none" which means no base hosts file is used. The default is
       "" which will use /etc/hosts.

       cgroups="enabled"

       Determines  whether  the  container will create CGroups.  Options are:
         enabled   Enable cgroup support within container

       with the container.

       default_capabilities=[]

       List of default capabilities for containers.

       The default list is:

              default_capabilities = [
              "AUDIT_WRITE",
                    "CHOWN",
                    "DAC_OVERRIDE",
                    "FOWNER",

                    "SYS_CHROOT",
              ]

       default_sysctls=[]

       A list of sysctls to be set in containers by default, specified as "name=value".

       Example:"net.ipv4.ping_group_range=0 1000".

       default_ulimits=[]

       A list of ulimits to be set in containers by default, specified as  "name=soft-limit:hard-
       limit".

       Example: "nofile=1024:2048".

       devices=[]

       List of devices.  Specified as 'device-on-host:device-on-container:permissions'.

       Example: "/dev/sdc:/dev/xvdc:rwm".

       dns_options=[]

       List of default DNS options to be added to /etc/resolv.conf inside of the container.

       dns_searches=[]

       List  of  default  DNS  search  domains  to  be  added  to  /etc/resolv.conf inside of the
       container.

       dns_servers=[]

       A list of dns servers to override the DNS  configuration  passed  to  the  container.  The
       special  value  “none”  can  be  specified  to disable creation of /etc/resolv.conf in the
       container.

       env=["PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin", "TERM=xterm"]

       Environment variable  list  for  the  container  process,  used  for  passing  environment

       Pass all host environment variables into the container.

       host_containers_internal_ip=""

       Set  the ip for the host.containers.internal entry in the containers /etc/hosts file. This
       can be set to "none" to disable adding this entry. By default it will automatically choose
       the host ip.

       NOTE:  When  using  podman  machine this entry will never be added to the containers hosts
       file instead the gvproxy dns resolver will resolve this  hostname.  Therefore  it  is  not
       possible to disable the entry in this case.

       http_proxy=true

       Default  proxy  environment  variables will be passed into the container.  The environment
       variables passed in include: http_proxy, https_proxy, ftp_proxy, no_proxy, and  the  upper
       case  versions  of  these. The no_proxy option is needed when host system uses a proxy but
       container should not use proxy. Proxy environment variables specified for the container in
       any other way will override the values passed from the host.

       init=false

       Run an init inside the container that forwards signals and reaps processes.

       init_path="/usr/libexec/podman/catatonit"

       Path  to  the  container-init  binary,  which  forwards signals and reaps processes within
       containers. Note that the container-init binary will only be  used  when  the  --init  for
       podman-create and podman-run is set.

       ipcns="shareable"

       Default way to to create a IPC namespace for the container.  Options are:
         host     Share host IPC Namespace with the container.
         none     Create shareable IPC Namespace for the container without a private /dev/shm.

       allowed to share it.
         shareable Create shareable IPC Namespace for the container.

       keyring=true

       Indicates whether the container engines  create  a  kernel  keyring  for  use  within  the
       container.

       label=true

       Indicates  whether  the  container  engine  uses  MAC(SELinux)  container  separation  via
       labeling. This option is ignored on disabled systems.

       log_driver=""

       Logging driver for the container. Currently available options are k8s-file, journald, none
       and  passthrough,  with  json-file  aliased  to k8s-file for scripting compatibility.  The
       journald driver is used by default if  the  systemd  journal  is  readable  and  writable.
       Otherwise, the k8s-file driver is used.

       log_size_max=-1

       Maximum  size allowed for the container's log file. Negative numbers indicate that no size
       limit is imposed. If it is positive, it must be >=  8192  to  match/exceed  conmon's  read
       buffer. The file is truncated and re-opened so the limit is never exceeded.

       log_tag=""

       Default  format tag for container log messages. This is useful for creating a specific tag
       for container log  messages.  Container  log  messages  default  to  using  the  truncated
       container ID as a tag.

       netns="private"

       Default way to to create a NET namespace for the container.  Options are:
         private Create private NET Namespace for the container.
         host    Share host NET Namespace with the container.
         none    Containers do not use the network.

       no_hosts=false

       Create  /etc/hosts  for  the  container.  By default, container engines manage /etc/hosts,
       automatically adding  the container's  own  IP  address.

       pidns="private"

       Default way to to create a PID namespace for the container.  Options are:
         private Create private PID Namespace for the container.
         host    Share host PID Namespace with the container.

       pids_limit=1024

       Maximum number of processes allowed in a container. 0 indicates that no limit is imposed.

       prepare_volume_on_create=false

       Copy the content from the  underlying  image  into  the  newly  created  volume  when  the
       container  is  created  instead of when it is started. If false, the container engine will
       not copy the content until the container is started. Setting it to true may have  negative
       performance implications.

       seccomp_profile="/usr/share/containers/seccomp.json"

       Path  to  the  seccomp.json  profile  which is used as the default seccomp profile for the
       runtime.

       shm_size="65536k"

       Size of /dev/shm. The format is <number><unit>. number must be greater than  0.   Unit  is
       optional  and  can  be:  b (bytes), k (kilobytes), m(megabytes), or g (gigabytes).  If you
       omit the unit, the system uses bytes. If you omit  the  size  entirely,  the  system  uses
       65536k.

       tz=""

       Set  timezone in container. Takes IANA timezones as well as local, which sets the timezone
       in the container to match the host machine.  If not set, then containers will run with the
       time zone specified in the image.

       Examples:
         tz="local"
         tz="America/New_York"

       umask="0022"

       Sets umask inside the container.

       userns="host"

       Default way to to create a USER namespace for the container.  Options are:
         private Create private USER Namespace for the container.
         host    Share host USER Namespace with the container.

       userns_size=65536

       Number  of  UIDs to allocate for the automatic container creation. UIDs are allocated from
       the “container” UIDs listed in /etc/subuid & /etc/subgid.

       utsns="private"

       Default way to to create a UTS namespace for the container.  Options are:
         private Create private UTS Namespace for the container.
         host    Share host UTS Namespace with the container.

       volumes=[]

       List of volumes.  Specified as "directory-on-host:directory-in-container:options".

       Example:  "/db:/var/lib/db:ro".

NETWORK TABLE

       The network table contains settings pertaining to the management of CNI plugins.

       network_backend=""

       Network backend determines what network driver will be  used  to  set  up  and  tear  down
       container  networks.   Valid  values are "cni" and "netavark".  The default value is empty
       which means that it will automatically choose  CNI  or  netavark.  If  there  are  already
       containers/images or CNI networks preset it will choose CNI.

       Before  changing  this  value  all  containers must be stopped otherwise it is likely that
       iptables rules and network interfaces might leak on the host. A reboot will fix this.

       cni_plugin_dirs=[]

       List of paths to directories where CNI plugin binaries are located.

       The default list is:

              cni_plugin_dirs = [

                "/usr/libexec/cni",
                "/usr/local/lib/cni",
                "/usr/lib/cni",
                "/opt/cni/bin",
              ]

       The network name of the default network to attach pods to.

       default_subnet="10.88.0.0/16"

       The subnet to use for the default  network  (named  above  in  default_network).   If  the
       default  network does not exist, it will be automatically created the first time a tool is
       run using this subnet.

       default_subnet_pools=[]

       DefaultSubnetPools is a list of subnets and  size  which  are  used  to  allocate  subnets
       automatically  for  podman network create.  It will iterate through the list and will pick
       the first free subnet with the given size. This  is  only  used  for  ipv4  subnets,  ipv6
       subnets are always assigned randomly.

       The default list is (10.89.0.0-10.255.255.0/24):

              default_subnet_pools = [
                {"base" = "10.89.0.0/16", "size" = 24},
                {"base" = "10.90.0.0/15", "size" = 24},
                {"base" = "10.92.0.0/14", "size" = 24},
                {"base" = "10.96.0.0/11", "size" = 24},
                {"base" = "10.128.0.0/9", "size" = 24},
              ]

       network_config_dir="/etc/cni/net.d/"

       Path  to the directory where network configuration files are located.  For the CNI backend
       the default is "/etc/cni/net.d" as root and "$HOME/.config/cni/net.d"  as  rootless.   For
       the  netavark backend "/etc/containers/networks" is used as root and "$graphroot/networks"
       as rootless.

       dns_bind_port=53

       Port to use for dns forwarding daemon  with  netavark  in  rootful  bridge  mode  and  dns
       enabled.   Using an alternate port might be useful if other dns services should run on the
       machine.

ENGINE TABLE

       The engine table contains configuration options used to set up container engines  such  as
       Podman and Buildah.

       active_service=""

       Name of destination for accessing the Podman service. See SERVICE DESTINATION TABLE below.

       cgroup_manager="systemd"

       The cgroup management implementation used for the runtime. Supports cgroupfs and systemd.

       conmon_env_vars=[]

       Environment variables to pass into Conmon.

       conmon_path=[]

       Paths  to  search  for  the  conmon container manager binary. If the paths are empty or no
       valid path was found, then the $PATH environment variable will be used as the fallback.

       The default list is:

              conmon_path=[
                  "/usr/libexec/podman/conmon",
                  "/usr/local/libexec/podman/conmon",
                  "/usr/local/lib/podman/conmon",
                  "/usr/bin/conmon",
                  "/usr/sbin/conmon",
                  "/usr/local/bin/conmon",
                  "/usr/local/sbin/conmon",
                  "/run/current-system/sw/bin/conmon",
              ]

       detach_keys="ctrl-p,ctrl-q"

       Keys sequence used for detaching a container.  Specify the keys sequence used to detach  a
       container.   Format  is  a  single  character  [a-Z]  or  a  comma  separated  sequence of
       ctrl-<value>, where <value> is one of: a-z, @, ^, [, \, ], ^ or _

       enable_port_reservation=true

       Determines whether the engine will reserve ports on the host when they  are  forwarded  to
       containers.  When  enabled,  when ports are forwarded to containers, they are held open by
       conmon as long as the container is running, ensuring that they cannot be reused  by  other
       programs  on the host. However, this can cause significant memory usage if a container has
       many ports forwarded to it.  Disabling this can save memory.

       env=[]

       Environment variables to  be  used  when  running  the  container  engine  (e.g.,  Podman,
       Buildah).  For  example  "http_proxy=internal.proxy.company.com".   Note these environment
       variables will not be used within the container. Set the env  section  under  [containers]
       table, if you want to set environment variables for the container.

       events_logfile_path=""

       Define where event logs will be stored, when events_logger is "file".

       events_logfile_max_size="1m"

       Sets  the maximum size for events_logfile_path.  The unit can be b (bytes), k (kilobytes),
       m (megabytes) or g (gigabytes).  The format for the size is <number><unit>,  e.g.,  1b  or
       3g.   If  no unit is included then the size will be in bytes.  When the limit is exceeded,
       the logfile will be rotated and the old one will be deleted.  If the maximumn size is  set
       to 0, then no limit will be applied, and the logfile will not be rotated.

       events_logger="journald"

       The default method to use when logging events.

       The  default  method is different based on the platform that Podman is being run upon.  To
       determine the current value, use this command:

       podman info --format {{.Host.EventLogger}

       Valid values are: file, journald, and none.

       helper_binaries_dir=["/usr/libexec/podman", ...]

       A is a list of directories which are used to search for helper binaries.

       The default paths on Linux are:  -  /usr/local/libexec/podman  -  /usr/local/lib/podman  -
       /usr/libexec/podman - /usr/lib/podman

       The  default  paths  on  macOS are: - /usr/local/opt/podman/libexec -    /opt/homebrew/bin
       -    /opt/homebrew/opt/podman/libexec  -   /usr/local/bin   -    /usr/local/libexec/podman
       -    /usr/local/lib/podman -    /usr/libexec/podman -    /usr/lib/podman

       The default path on Windows is: - C:\Program Files\RedHat\Podman

       hooks_dir=["/etc/containers/oci/hooks.d", ...]

       Path to the OCI hooks directories for automatically executed hooks.

       image_default_format="oci"|"v2s2"|"v2s1"

       Manifest  Type  (oci,  v2s2,  or  v2s1)  to  use when pulling, pushing, building container
       images. By default images pulled  and  pushed  match  the  format  of  the  source  image.
       Building/committing defaults to OCI.  Note: image_build_format is deprecated.

       image_default_transport="docker://"

       Default transport method for pulling and pushing images.

       image_parallel_copies=0

       Maximum  number  of image layers to be copied (pulled/pushed) simultaneously.  Not setting
       this field will fall back to containers/image defaults. (6)

       image_volume_mode="bind"

       Tells container engines how to handle the builtin image volumes.

              • bind: An  anonymous  named  volume  will  be   created   and   mounted  into  the
                container.

              • tmpfs:  The  volume  is  mounted  onto the container as a tmpfs, which allows the
                users to create content that disappears when the container is stopped.

              • ignore: All volumes are just ignored and no action is taken.

       infra_command="/pause"

       Infra (pause) container image command for pod infra containers. When  running  a  pod,  we
       start a /pause process in a container to hold open the namespaces associated with the pod.
       This container does nothing other  then  sleep,  reserving  the  pods  resources  for  the
       lifetime of the pod.

       infra_image=""

       Infra  (pause)  container  image  for pod infra containers. When running a pod, we start a
       pause process in a container to hold open the namespaces associated  with  the  pod.  This
       container  does nothing other then sleep, reserving the pods resources for the lifetime of
       the pod. By default container engines run a builtin container using the pause  executable.
       If you want override specify an image to pull.

       lock_type="shm"

       Specify  the  locking  mechanism  to  use;  valid values are "shm" and "file".  Change the
       default only if you are sure of what you are doing, in general "file" is  useful  only  on
       platforms where cgo is not available for using the faster "shm" lock type. You may need to
       run "podman system renumber" after you change the lock type.

       multi_image_archive=false

       Allows for creating archives (e.g., tarballs) with more than  one  image.  Some  container
       engines, such as Podman, interpret additional arguments as tags for one image and hence do
       not store more than one image. The default behavior can be altered with this option.

       namespace=""

       Default engine namespace. If the engine is  joined  to  a  namespace,  it  will  see  only
       containers  and  pods  that  were  created  in  the  same  namespace,  and will create new
       containers and pods in that namespace. The default namespace is "", which  corresponds  to
       no namespace. When no namespace is set, all containers and pods are visible.

       network_cmd_path=""

       Path to the slirp4netns binary.

       network_cmd_options=[]

       Default options to pass to the slirp4netns binary.

       Valid options values are:

              • allow_host_loopback=true|false:  Allow the slirp4netns to reach the host loopback
                IP (10.0.2.2). Default is false.

              • mtu=MTU: Specify the MTU to use for this network. (Default is 65520).

              • cidr=CIDR: Specify ip range to use for this network. (Default is 10.0.2.0/24).

              • enable_ipv6=true|false:   Enable   IPv6.   Default   is   true.   (Required   for
                outbound_addr6).

              • outbound_addr=INTERFACE:  Specify  the  outbound  interface  slirp should bind to
                (ipv4 traffic only).

              • outbound_addr=IPv4: Specify the outbound ipv4 address slirp should bind to.

              • outbound_addr6=INTERFACE: Specify the outbound interface  slirp  should  bind  to
                (ipv6 traffic only).

              • outbound_addr6=IPv6: Specify the outbound ipv6 address slirp should bind to.

              • port_handler=rootlesskit:  Use  rootlesskit  for port forwarding. Default.  Note:
                Rootlesskit changes the source IP address of incoming packets to a IP address  in
                the container network namespace, usually 10.0.2.100. If your application requires
                the real source IP address, e.g.  web  server  logs,  use  the  slirp4netns  port
                handler.  The  rootlesskit port handler is also used for rootless containers when
                connected to user-defined networks.

              • port_handler=slirp4netns: Use the slirp4netns port forwarding, it is slower  than
                rootlesskit but preserves the correct source IP address. This port handler cannot
                be used for user-defined networks.

       no_pivot_root=false

       Whether to use chroot instead of pivot_root in the runtime.

       num_locks=2048

       Number of locks available for containers and pods. Each created container or pod  consumes
       one  lock.  The  default  number available is 2048. If this is changed, a lock renumbering
       must be performed, using the podman system renumber command.

       pod_exit_policy="continue"

       Set the exit policy of the pod when the last container exits.  Supported policies are:

       ┌────────────┬──────────────────────────────────┐
       │Exit PolicyDescription                      │
       ├────────────┼──────────────────────────────────┤
       │continue    │ The pod continues  running  when │
       │            │ the  last  container exits. Used │
       │            │ by default.                      │
       ├────────────┼──────────────────────────────────┤
       │stop        │ The pod is stopped when the last │
       │            │ container  exits.  Used  in play │
       │            │ kube.                            │
       └────────────┴──────────────────────────────────┘

       pull_policy="always"|"missing"|"never"

       Pull image before running or creating a container. The default is missing.

              • missing: attempt  to  pull  the  latest  image  from  the  registries  listed  in
                registries.conf  if  a local image does not exist. Raise an error if the image is
                not in any listed registry and is not present locally.

              • always: pull the image from the first registry  it  is  found  in  as  listed  in
                registries.conf. Raise an error if not found in the registries, even if the image
                is present locally.

              • never: do not pull the image from the registry, use only the local version. Raise
                an error if the image is not present locally.

       remote  =  false  Indicates whether the application should be running in remote mode. This
       flag modifies the --remote option on container engines. Setting  the  flag  to  true  will
       default podman --remote=true for access to the remote Podman service.

       runtime=""

       Default  OCI  specific  runtime  in runtimes that will be used by default. Must refer to a
       member of the runtimes table. Default runtime will be searched for on the system using the
       priority: "crun", "runc", "kata".

       runtime_supports_json=["crun", "runc", "kata", "runsc", "krun"]

       The list of the OCI runtimes that support --format=json.

       runtime_supports_kvm=["kata", "krun"]

       runtime_supports_nocgroups=["crun", "krun"]

       The list of OCI runtimes that support running containers without CGroups.

       image_copy_tmp_dir="/var/tmp"

       Default location for storing temporary container image content. Can be overridden with the
       TMPDIR  environment  variable.  If  you  specify  "storage",  then  the  location  of  the
       container/storage  tmp  directory will be used. If set then it is the users responsibility
       to cleanup storage. Configure tmpfiles.d(5) to cleanup storage.

       service_timeout=5

       Number of seconds to wait without a connection  before the podman system service times out
       and exits

       static_dir="/var/lib/containers/storage/libpod"

       Directory for persistent libpod files (database, etc).  By default this will be configured
       relative to where containers/storage stores containers.

       stop_timeout=10

       Number of seconds to wait for container to exit before sending kill signal.

       exit_command_delay=300

       Number of seconds to wait for the API process  for  the  exec  call  before  sending  exit
       command mimicking the Docker behavior of 5 minutes (in seconds).

       tmp_dir="/run/libpod"

       The  path  to  a  temporary directory to store per-boot container.  Must be a tmpfs (wiped
       after reboot).

       volume_path="/var/lib/containers/storage/volumes"

       Directory where named volumes will be created in using  the  default  volume  driver.   By
       default  this  will  be  configured relative to where containers/storage store containers.
       This convention is followed by the default volume driver, but may not be by other drivers.

       chown_copied_files=true

       Determines whether file copied into a container will have changed ownership to the primary
       uid/gid of the container.

       compression_format=""

       Specifies the compression format to use when pushing an image. Supported values are: gzip,
       zstd and zstd:chunked.

SERVICE DESTINATION TABLE

       The service_destinations table contains  configuration  options  used  to  set  up  remote
       connections to the podman service for the podman API.

       [service_destinations.{name}]      URI      to      access      the     Podman     service
       uri="ssh://user@production.example.com/run/user/1001/podman/podman.sock"

       Path to file containing ssh identity key

       [engine.volume_plugins]

       A table of all the enabled volume plugins on the system. Volume plugins can be used as the
       backend for Podman named volumes. Individual plugins are specified below, as a map of  the
       plugin  name  (what  the plugin will be called) to its path (filepath of the plugin's unix
       socket).

SECRET TABLE

       The secret table contains settings for the configuration of the secret subsystem.

       driver=file

       Name of the secret driver to be used.  Currently valid values are:
         * file
         * pass

       [secrets.opts]

       The driver specific options object.

MACHINE TABLE

       The machine table contains configurations for podman machine VMs

       cpus=1 Number of CPU's a machine is created with.

       disk_size=10

       The size of the disk in GB created when init-ing a podman-machine VM

       image=""

       Default image URI when  creating  a  new  VM  using  podman  machine  init.   Options:  On
       Linux/Mac,  testing,  stable,  next.  On Windows, the major version of the OS (e.g 36) for
       Fedora 36. For all platforms you can alternatively specify a custom  download  URL  to  an
       image.  Container  engines  translate  URIs  $OS  and $ARCH to the native OS and ARCH. URI
       "https://example.com/$OS/$ARCH/foobar.ami"                  would                   become
       "https://example.com/linux/amd64/foobar.ami" on a Linux AMD machine.  The default value is
       testing on Linux/Mac, and on Windows.

       memory=2048

       Memory in MB a machine is created with.

       user=""

       Username to use and create on the podman machine OS for  rootless  container  access.  The
       default value is user. On Linux/Mac the default iscore.

       volumes=["$HOME:$HOME"]

       Host  directories  to be mounted as volumes into the VM by default.  Environment variables
       like $HOME as well as complete paths are supported for  the  source  and  destination.  An
       optional  third  field  :ro  can be used to tell the container engines to mount the volume
       readonly.

FILES

       containers.conf

       Distributions often provide a /usr/share/containers/containers.conf file to define default
       container  configuration.  Administrators  can  override  fields  in this file by creating
       /etc/containers/containers.conf to specify their own  configuration.  Rootless  users  can
       further  override  fields  in  the  config  by  creating  a  config  file  stored  in  the
       $HOME/.config/containers/containers.conf file.

       If the CONTAINERS_CONF path environment variable is set, just this path will be used. This
       is primarily used for testing.

       Fields  specified  in  the  containers.conf  file override the default options, as well as
       options in previously read containers.conf files.

       storage.conf

       The /etc/containers/storage.conf file is the default storage configuration file.  Rootless
       users     can     override     fields     in    the    storage    config    by    creating
       $HOME/.config/containers/storage.conf.

       If the CONTAINERS_STORAGE_CONF path environment variable is set, this path is used for the
       storage.conf file rather than the default.  This is primarily used for testing.
