Seed custom containers

This section covers configuration of the user-defined containers deployment functionality that runs on the seed host.

Configuration

For example, to deploy a squid container image:

seed_containers:
  squid:
    image: "stackhpc/squid:3.5.20-1"
    pre: "{{ kayobe_config_path }}/containers/squid/pre.yml"
    post: "{{ kayobe_config_path }}/containers/squid/post.yml"

Please notice the optional pre and post Ansible task files - those need to be created in kayobe-config path and will be run before and after particular container deployment.

Possible options for container deployment:

seed_containers:
  containerA:
    capabilities:
    command:
    comparisons:
    detach:
    env:
    network_mode:
    image:
    init:
    ipc_mode:
    pid_mode:
    ports:
    privileged:
    restart_policy:
    shm_size:
    sysctls:
    tag:
    ulimits:
    user:
    volumes:

For a detailed explanation of each option - please see Ansible docker_container module page.
