Docker Swarm Management

!DEPRECATED!

Please follow new source:

• https://github.com/hansehe/SwarmManagement

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
   • 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.

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.
