NAME

       runc-exec - execute new process inside the container

SYNOPSIS

       runc exec [option ...] container-id [--] command [arg ...]

       runc exec [option ...] -p process.json container-id

OPTIONS

       --console-socket path : Path to an AF_UNIX  socket which will receive a file descriptor
       referencing the master end of the console's pseudoterminal.  See docs/terminals
       ⟨https://github.com/opencontainers/runc/blob/master/docs/terminals.md⟩.

       --cwd path : Change to path in the container before executing the command.

       --env|-e name=value : Set an environment variable name to value. Can be specified multiple
       times.

       --tty|-t : Allocate a pseudo-TTY.

       --user|-u uid[:gid] : Run the command as a user (and, optionally, group) specified by uid
       (and gid).

       --additional-gids|-g gid : Add additional group IDs. Can be specified multiple times.

       --process|-p process.json : Instead of specifying all the exec parameters directly on the
       command line, get them from a process.json, a JSON file containing the process
       specification as defined by the OCI runtime spec
       ⟨https://github.com/opencontainers/runtime-spec/blob/master/config.md#process⟩.

       --detach|-d : Detach from the container's process.

       --pid-file path : Specify the file to write the container process' PID to.

       --process-label label : Set the asm process label for the process commonly used with
       selinux(7).

       --apparmor profile : Set the apparmor(7) profile for the process.

       --no-new-privs : Set the "no new privileges" value for the process.

       --cap cap : Add a capability to the bounding set for the process. Can be specified
       multiple times.

       --preserve-fds N : Pass N additional file descriptors to the container (stdio +
       $LISTEN_FDS + N in total). Default is 0.

       --ignore-paused : Allow exec in a paused container. By default, if a container is paused,
       runc exec errors out; this option can be used to override it.  A paused container needs to
       be resumed for the exec to complete.

       --cgroup path | controller[,controller...]:path : Execute a process in a sub-cgroup. If
       the specified cgroup does not exist, an error is returned. Default is empty path, which
       means to use container's top level cgroup.  : For cgroup v1 only, a particular controller
       (or multiple comma-separated controllers) can be specified, and the option can be used
       multiple times to set different paths for different controllers.  : Note for cgroup v2, in
       case the process can't join the top level cgroup, runc exec fallback is to try joining the
       cgroup of container's init.  This fallback can be disabled by using --cgroup /.

EXIT STATUS

       Exits with a status of command (unless -d is used), or 255 if an error occurred.

EXAMPLES

       If the container can run ps(1) command, the following will output a list of processes
       running in the container:

              # runc exec <container-id> ps
