NAME

       ocf_heartbeat_docker - Docker container resource agent.

SYNOPSIS

       docker [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

       The docker HA resource agent creates and launches a docker container based off a supplied
       docker image. Containers managed by this agent are both created and removed upon the
       agent's start and stop actions.

SUPPORTED PARAMETERS

       image
           The docker image to base this container off of.

           (required, string, no default)

       name
           The name to give the created container. By default this will be that resource's
           instance name.

           (optional, string, no default)

       allow_pull
           Allow the image to be pulled from the configured docker registry when the image does
           not exist locally. NOTE, this can drastically increase the time required to start the
           container if the image repository is pulled over the network.

           (optional, boolean, no default)

       run_opts
           Add options to be appended to the 'docker run' command which is used when creating the
           container during the start action. This option allows users to do things such as
           setting a custom entry point and injecting environment variables into the newly
           created container. Note the '-d' option is supplied regardless of this value to force
           containers to run in the background.

           NOTE: Do not explicitly specify the --name argument in the run_opts. This agent will
           set --name using either the resource's instance or the name provided in the 'name'
           argument of this agent.

           (optional, string, no default)

       run_cmd
           Specifiy a command to launch within the container once it has initialized.

           (optional, string, no default)

       monitor_cmd
           Specifiy the full path of a command to launch within the container to check the health
           of the container. This command must return 0 to indicate that the container is
           healthy. A non-zero return code will indicate that the container has failed and should
           be recovered.

           The command is executed using nsenter. In the future 'docker exec' will be used once
           it is more widely supported.

           (optional, string, no default)

       force_kill
           Kill a container immediately rather than waiting for it to gracefully shutdown

           (optional, boolean, no default)

       reuse
           Allow the container to be reused after stopping the container. By default containers
           are removed after stop. With the reuse option containers will persist after the
           container stops.

           (optional, boolean, no default)

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
           Starts the resource. Suggested minimum timeout: 90.

       stop
           Stops the resource. Suggested minimum timeout: 90.

       monitor
           Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval:
           30.

       meta-data
           Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.

       validate-all
           Performs a validation of the resource configuration. Suggested minimum timeout: 30.

EXAMPLE CRM SHELL

       The following is an example configuration for a docker resource using the crm(8) shell:

           primitive p_docker ocf:heartbeat:docker \
             params \
               image=string \
             op monitor timeout="30" interval="30" depth="0"

EXAMPLE PCS

       The following is an example configuration for a docker resource using pcs(8)

           pcs resource create p_docker ocf:heartbeat:docker \
             image=string \
             op monitor timeout="30" interval="30" depth="0"
