NAME¶
ocf_heartbeat_rkt - rkt container resource agent.
SYNOPSIS¶
rkt [start | stop | monitor | meta-data | validate-all]
DESCRIPTION¶
The rkt HA resource agent creates and launches a container based off a supplied image. Containers managed by this agent are both created and removed upon the agent's start and stop actions.
SUPPORTED PARAMETERS¶
image
(required, string, no default)
name
(optional, string, no default)
allow_pull
(optional, boolean, no default)
run_opts
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
(optional, string, no default)
mount_points
(optional, string, no default)
monitor_cmd
Note: Using this method for monitoring processes inside a container is not recommended, as rkt tries to track processes running inside the container and does not deal well with many short-lived processes being spawned. Ensure that your container monitors its own processes and terminates on fatal error rather than invoking a command from the outside.
(optional, string, no default)
force_kill
(optional, boolean, no default)

This resource agent supports the following actions (operations):
start
