Description

The Lima module is a "glue" between Puppet Bolt and lima

Requirements

You will need to have installed limactl on the system you wish to run Bolt from.

Inventory plugin usage

The resolve_reference task supports looking up target objects from a limactl list output. It accepts following parameters:

• limactl: Location of the limactl binary if not in $PATH.
• only_matching_names: Only VM with names matching this regex will be included into the inventory. This regex is passed to Regexp.new() as a string.
• except_matching_names: VMs with names matching this regex will be excluded from the inventory. This regex is passed to Regexp.new() as a string.

NOTE 1: Only running VMs are returned.

NOTE 2: If both only_matching_names and except_matching_names are specified then only VMs matching only_matching_names and not matching except_matching_names are returned.

Examples

groups:
  - name: lima-vms
    targets:
      - _plugin: lima
        except_matching_names: '^default'

Cluster management plans usage

This module provides a way to define and manage clusters of Lima VMs. It's expected to define clusters in the plan_hierarchy of your Bolt project's Hiera.

Below is the example of a Hiera file under plan_hierarchy:

---
# Leverage YAML features to define templates required
x-ubuntu2004: &ubuntu2004
  images:
  - location: "https://cloud-images.ubuntu.com/releases/20.04/release-20230117/ubuntu-20.04-server-cloudimg-amd64.img"
    arch: "x86_64"
    digest: "sha256:3e44e9f886eba6b91662086d24028894bbe320c1de89be5c091019fedf9c5ce6"
  - location: "https://cloud-images.ubuntu.com/releases/20.04/release-20230117/ubuntu-20.04-server-cloudimg-arm64.img"
    arch: "aarch64"
    digest: "sha256:4ea4700f7b1de194a2f6bf760b911ea3071e0309fcea14d3a465a3323d57c60e"
  - location: "https://cloud-images.ubuntu.com/releases/20.04/release/ubuntu-20.04-server-cloudimg-amd64.img"
    arch: "x86_64"
  - location: "https://cloud-images.ubuntu.com/releases/20.04/release/ubuntu-20.04-server-cloudimg-arm64.img"
    arch: "aarch64"

  - location: "~"

# Cluster definitions
lima::clusters:
  example: # `example` cluster
    nodes:
      - example1
        template: ubuntu  # Use latest ubuntu version on this VM
      - example2
      - example3
    config:
      <<: *ubuntu2004

Now when you have some clusters defined you can use cluster management plans to start/stop/delete a cluster. E.g.:

# Start the cluster (create example[123] VMs)
bolt plan run lima::cluster::start name=example
# Stop the cluster (stop example[123] VMs)
bolt plan run lima::cluster::stop name=example
# Delete the cluster (delete example[123] VMs)
bolt plan run lima::cluster::delete name=example
