Docker with Puppet Configuring Health checks periodically on an unhealthy Docker container

Question

I have an unhealthy docker container that I wish to restart and also configure health check interval every 20 seconds? How do I go about doing this?

Answer 1

To enable the restart of an unhealthy container, add the following code to the manifest file.

 In order to set the health check interval time set the optional health_check_interval parameter, the default health check interval is 30 seconds.

docker::run { 'helloworld':
  image => 'base',
  command => 'command',
  health_check_cmd => '<command_to_execute_to_check_your_containers_health>',
  restart_on_unhealthy => true,
  health_check_interval => '<time between running docker healthcheck>', //in your case 20 sec.
