NAME
container-server.conf - configuration file for the openstack-swift container server
SYNOPSIS
container-server.conf
DESCRIPTION
This is the configuration file used by the container server and other container background
services, such as; replicator, updater, auditor and sync.
The configuration file follows the python-pastedeploy syntax. The file is divided into
sections, which are enclosed by square brackets. Each section will contain a certain
number of key/value parameters which are described later.
Any line that begins with a '#' symbol is ignored.
You can find more information about python-pastedeploy configuration format at
http://pythonpaste.org/deploy/#config-format
GLOBAL SECTION
This is indicated by section named [DEFAULT]. Below are the parameters that are acceptable
within this section.
bind_ip
IP address the container server should bind to. The default is 0.0.0.0 which will
make it bind to all available addresses.
bind_port
TCP port the container server should bind to. The default is 6001.
backlog
TCP backlog. Maximum number of allowed pending connections. The default value is
4096.
workers
The number of pre-forked processes that will accept connections. Zero means no
fork. The default is auto which will make the server try to match the number of
effective cpu cores if python multiprocessing is available (included with most
python distributions >= 2.6) or fallback to one. It's worth noting that individual
workers will use many eventlet co-routines to service multiple concurrent requests.
max_clients
Maximum number of clients one worker can process simultaneously (it will actually
accept(2) N + 1). Setting this to one (1) will only handle one request at a time,
without accepting another request concurrently. The default is 1024.
user The system user that the container server will run as. The default is swift.
swift_dir
Swift configuration directory. The default is /etc/swift.
devices
Parent directory or where devices are mounted. Default is /srv/node.
mount_check
Whether or not check if the devices are mounted to prevent accidentally writing to
the root device. The default is set to true.
log_name
Label used when logging. The default is swift.
log_facility
Syslog log facility. The default is LOG_LOCAL0.
log_level
Logging level. The default is INFO.
log_address
Logging address. The default is /dev/log.
PIPELINE SECTION
This is indicated by section name [pipeline:main]. Below are the parameters that are
acceptable within this section.
pipeline
It is used when you need to apply a number of filters. It is a list of filters
ended by an application. The normal pipeline is "healthcheck recon container-
server".
APP SECTION
This is indicated by section name [app:container-server]. Below are the parameters that
are acceptable within this section.
use Entry point for paste.deploy for the container server. This is the reference to the
installed python egg. This is normally egg:swift#container.
set log_name
Label used when logging. The default is container-server.
set log_facility
Syslog log facility. The default is LOG_LOCAL0.
set log_level
Logging level. The default is INFO.
set log_requests
Enables request logging. The default is True.
set log_address
Logging address. The default is /dev/log.
node_timeout
Request timeout to external services. The default is 3 seconds.
conn_timeout
Connection timeout to external services. The default is 0.5 seconds.
FILTER SECTION
Any section that has its name prefixed by "filter:" indicates a filter section. Filters
are used to specify configuration parameters for specific swift middlewares. Below are
the filters available and respective acceptable parameters.
[filter:healthcheck]
use Entry point for paste.deploy for the healthcheck middleware. This is the
reference to the installed python egg. This is normally egg:swift#healthcheck.
disable_path
An optional filesystem path which, if present, will cause the healthcheck URL to
return "503 Service Unavailable" with a body of "DISABLED BY FILE".
[filter:recon]
use Entry point for paste.deploy for the recon middleware. This is the reference to
the installed python egg. This is normally egg:swift#recon.
recon_cache_path
The recon_cache_path simply sets the directory where stats for a few items will
be stored. Depending on the method of deployment you may need to create this
directory manually and ensure that swift has read/write. The default is
/var/cache/swift.
ADDITIONAL SECTIONS
The following sections are used by other swift-container services, such as replicator,
updater, auditor and sync.
[container-replicator]
log_name
Label used when logging. The default is container-replicator.
log_facility
Syslog log facility. The default is LOG_LOCAL0.
log_level
Logging level. The default is INFO.
log_address
Logging address. The default is /dev/log.
vm_test_mode
Indicates that you are using a VM environment. The default is no.
er_diff
The default is 1000.
max_diffs
This caps how long the replicator will spend trying to sync a given database per
pass so the other databases don't get starved. The default is 100.
concurrency
Number of replication workers to spawn. The default is 8.
run_pause [deprecated]
Time in seconds to wait between replication passes. The default is 10.
interval
Replaces run_pause with the more standard "interval", which means the replicator
won't pause unless it takes less than the interval set. The default is 30.
node_timeout
Request timeout to external services. The default is 10 seconds.
conn_timeout
Connection timeout to external services. The default is 0.5 seconds.
reclaim_age
Time elapsed in seconds before an container can be reclaimed. The default is
604800 seconds.
[container-updater]
log_name
Label used when logging. The default is container-updater.
log_facility
Syslog log facility. The default is LOG_LOCAL0.
log_level
Logging level. The default is INFO.
log_address
Logging address. The default is /dev/log.
interval
Minimum time for a pass to take. The default is 300 seconds.
concurrency
Number of reaper workers to spawn. The default is 4.
node_timeout
Request timeout to external services. The default is 3 seconds.
conn_timeout
Connection timeout to external services. The default is 0.5 seconds.
slowdown
Slowdown will sleep that amount between containers. The default is 0.01 seconds.
account_suppression_time
Seconds to suppress updating an account that has generated an error. The default
is 60 seconds.

log_level
Logging level. The default is INFO.
log_address
Logging address. The default is /dev/log.
interval
Will audit, at most, 1 container per device per interval. The default is 1800
seconds.
containers_per_second
Maximum containers audited per second. Should be tuned according to individual
system specs. 0 is unlimited. The default is 200.
[container-sync]
log_name
Label used when logging. The default is container-sync.
log_facility
Syslog log facility. The default is LOG_LOCAL0.
log_level
Logging level. The default is INFO.
log_address
Logging address. The default is /dev/log.
