Docker Swarm Management

PyPI version Build Status MIT license

Swarm Management is a python application, installed with pip. The application makes it easy to manage a Docker Swarm by configuring a single *.yml file describing which stacks to deploy, and which networks, configs or secrets to create.

Install Or Upgrade

  • pip install --upgrade SwarmManagement

Verify Installation

  • swm -help

Example

  1. Create a swarm.management.yml file describing all properties of the swarm.

    • The swarm.management.yml file contains following properties:
    stacks:
        <stack_name>: <compose_file>
    networks:
        <network_name>: 
            encrypted: false
            driver: overlay
            attachable: true
            options:
              - --ipv6
    configs:
        <config_name>: <config_file>
    secrets:
        <secret_name>: <secret_file>
    volumes:
        <volume_name>:
            driver: local
            driverOptions:
              - type=tmpfs
              - device=tmpfs
              - o=size=100m,uid=1000
    env_files:
        - <environment_file>
  2. Manage Swarm:

    • Start Swarm with:
      • -> swm -start
    • Stop Swarm with:
      • -> swm -stop
    • Restart Swarm with:
      • -> swm -restart
    • Wait for all services to start in Swarm with:
      • -> swm -wait
    • Deploy/Update or Remove a single stack:
      • -> swm -stack -deploy <stack_name>
      • -> swm -stack -remove <stack_name>
      • Or deploy/remove all stacks with the all attribute:
        • -> swm -stack -deploy all
        • -> swm -stack -remove all
    • Create or Remove a single network:
      • -> swm -network -create <network_name>
      • -> swm -network -remove <network_name>
      • Or create/remove all networks with the all attribute:
        • -> swm -network -create all
        • -> swm -network -remove all
    • Create or Remove a single config:
      • -> swm -config -create <config_name>
      • -> swm -config -remove <config_name>
      • Or create/remove all configs with the all attribute:
        • -> swm -stack -create all
        • -> swm -stack -remove all
    • Create or Remove a single secret:
      • -> swm -secret -create <secret_name>
      • -> swm -secret -remove <secret_name>
      • Or create/remove all secrets with the all attribute:
        • -> swm -secret -create all
        • -> swm -secret -remove all
    • Create or Remove a single volume:
      • -> swm -volume -create <volume_name>
      • -> swm -volume -remove <volume_name>
      • Or create/remove all volumes with the all attribute:
        • -> swm -volume -create all
        • -> swm -volume -remove all
    • SwarmManagement uses the swarm.management.yml file by default to configure the swarm.
      • Specify a single or multiple *.yml files to use for configuring the swarm using the -f attribute:
        • -> swm -start -f swarm-stacks.yml -f swarm-networks.yml
    • Additional info is found by asking SwarmManagement:
      • -> swm -help
      • -> swm -stack -help
      • -> swm -network -help
      • -> swm -config -help
      • -> swm -secret -help
      • -> swm -volume -help

Section Features

Start/Stop or Restart Swarm

Deploy the swarm with swm -start, and stop the swarm with swm -stop. Restart the swarm with swm -restart <restart_delay_in_seconds>. The <restart_delay_in_seconds> argument is optional, and defaults to 10 seconds if not given. Wait for all services in the swarm to start with swm -wait <timeout_in_seconds> <service_to_target>. The <timeout_in_seconds> argument is optional, and defaults to 120 seconds if not given. The <service_to_target> argument is optional, and is a list of specific service names to target.

Stacks

The stacks section lists all stacks to be deployed as: <stack_name>: <compose_file>

Networks

The networks section lists all networks to be created as, and each network is created with the following default properties:

  • encrypted: false
  • driver: overlay
  • attachable: true
  • options:
    • <list_of_network_options>

Configs

The configs section lists all configs to be created as: <config_name>: <config_file>

Secrets

The secrets section lists all secrets to be created as: <secret_name>: <secret_file>

Volumes

The volumes section lists all volumes to be created as, and each volumes is created with the following default properties:

  • driver: local
  • driverOptions:
    • <list_of_driver_options>

Environment variables

The env_files section lists all environmnet (.env) files with environment variables to expose. By convention, a present .env file will automatically be loaded.
