rkt-runner

An Ansible role for creating a systemd service unit that runs an ACI using rkt.

Requirements

Assumes that rkt is already installed on the target system and is available at /usr/bin/rkt.

Requires systemd. The Wikipedia article for systemd lists the Linux distributions and corresponding versions that come with systemd out of the box.

Role Variables

This role has two required variables:

• image_path: the path to the ACI (eg. /images/cool-thing.aci or http://www.example.com/cool-thing.aci or example.com/cool-thing:v1.2.3)
• service_name: the name of the service (eg. cool-thing)

There are also two optional variables:

• extra_args: arguments to pass through to the container's executable (eg. setting extra_args to --do-stuff will result in the rkt run command being /usr/bin/rkt run /path/to/image.aci -- --do-stuff)
• rkt_opts: rkt options (eg. https://coreos.com/rkt/docs/latest/subcommands/run.html)

Dependencies

This role does not have any dependencies.

Example Playbook

- hosts: servers
  roles:
     - { role: rkt-runner, image_path: "/images/cool-thing.aci", service_name: "cool-thing" }
