5.0 quality score

We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below
is for guidance only and neither of
these methods should be considered
an endorsement by Puppet.

Documentation

glorpen/g_docker — version 1.7.0 May 14th 2020

g-docker

Configures Docker daemon and allows running containers as system services.

The main target of this module is running containerized apps as system services when not using cluster supervisor (Docker Swarm, Kubernetes, ...).

Helpful features

  • containers can be reloaded upon managed configuration changes - no restarting
  • persistent container data stored on managed LVM volumes
  • binding specific folders to container
  • manageable firewall - automatic rules created by Docker are accounted for by Puppet, you can safely purge unmanaged firewall rules
  • pluggable storage and firewall modules

Usage

Setup

Remember to enable and configure choosen firewall and storage driver.

include ::g_docker::firewall::native
include ::g_docker::storage::overlay2

class { ::g_docker: }

Creating containers:

Hiera:

g_docker::instances:
  example:
    image: example:latest
    env:
      MY_ENV: "some env"
    volumes:
      data:
        size: 30G
        binds:
          home:
            path: /data
            readonly: false
            user: 1000
            group: 1000
            mode: a=rx,u+w

Runtime configs and reloading

You can create small configuration files with puppet and mount it inside containers.

Hiera:

g_docker::instances:
  example:
    # ...
    runtime_configs:
      pupppetizer:
        target: /var/opt/puppetizer/hiera
        configs:
          "runtime.yaml":
            reload: true
            source: puppet:///modules/profile/proxy.yaml

or Puppet DSL:

g_docker::run { 'example-1':
  ensure => present,
  image => 'example:latest',
  runtime_configs => {
    'puppetizer' => {
      'target' => '/var/opt/puppetizer/hiera',
      'configs' => {
        'runtime.yaml' => {
          'reload' => true,
          'source' => 'puppet:///modules/profile/proxy.yaml',
        },
      },
    },
  },
}

Following example works identically to previous one:

g_docker::run { 'example-1':
  ensure => present,
  image => 'example:latest',
  runtime_configs => {
    'puppetizer' => {
      'target' => '/var/opt/puppetizer/hiera',
      },
    },
  },
}

g_docker::runtime_config::config { 'example':
  container => 'example-1',
  group     => 'puppetizer',
  filename  => 'runtime.yaml',
  reload    => true,
  source    => 'puppet:///modules/profile/proxy.yaml',
}
