docker_service_manager_execute

The docker_service_manager_execute resource manages the Docker daemon using Chef's execute resources. This is a basic service manager that uses shell commands to start, stop, and restart the Docker daemon.

Actions

  • :start - Starts the Docker daemon
  • :stop - Stops the Docker daemon
  • :restart - Restarts the Docker daemon (stop followed by start)

Properties

This resource inherits properties from the docker_service_base resource. Common properties include:

Property Type Default Description
docker_daemon_cmd String Generated Command to start the Docker daemon
logfile String Based on name Path to the log file
pidfile String Based on name Path to the PID file
http_proxy String nil HTTP proxy settings
https_proxy String nil HTTPS proxy settings
no_proxy String nil No proxy settings
tmpdir String nil Temporary directory path

Examples

Basic Usage

docker_service_manager_execute 'default' do
  action :start
end

Start Docker with Custom Settings

docker_service_manager_execute 'default' do
  http_proxy 'http://proxy.example.com:3128'
  https_proxy 'http://proxy.example.com:3128'
  no_proxy 'localhost,127.0.0.1'
  action :start
end

Stop Docker Service

docker_service_manager_execute 'default' do
  action :stop
end

Restart Docker Service

docker_service_manager_execute 'default' do
  action :restart
end

Notes

  • This resource enables IPv4 and IPv6 forwarding using sysctl
  • The Docker daemon is started as a background process using bash
  • A wait script is created to ensure the daemon is ready before proceeding
  • The stop action uses a timeout of 10 seconds when stopping the daemon
  • The resource uses process checking to prevent duplicate daemon instances
  • Log output is redirected to the specified logfile
  • Environment variables (HTTP_PROXY, HTTPS_PROXY, NO_PROXY, TMPDIR) are passed to the daemon process

Platform Support

This resource should work on any platform that can run the Docker daemon, but it's primarily tested on Linux systems.
