This release revamps the runner pod manifest configuration. The migration steps depend on the value you are currently passing:

  • If you are currently passing a map or a callback to :runner_pod_tpl, you can simply rename the option to :manifest and it should maintain the current behaviour.

  • If you are using %FLAMEK8sBackend.RunnerPodTemplate{} with :env and/or :resources fields, you need to convert it into a manifest map.

    manifest = %{
  "spec" => %{
    "containers" => [
      %{
        "env" => [
          %{"name" => "FOO", "value" => "bar"}
        ],
        "resources" => %{
          "requests" => %{"memory" => "256Mi", "cpu" => "100m"},
          "limits" => %{"memory" => "256Mi", "cpu" => "400m"}
        }
      }
    ]
  }
}

{FLAME.Pool,
  name: MyApp.SamplePool,
  backend: {FLAMEK8sBackend, manifest: manifest}}

    Note that, by default, using %FLAMEK8sBackend.RunnerPodTemplate{} implied that envs and resources were copied from the parent pod. If you want to maintain that behaviour, you can use a manifest function, as fallows:

      manifest_fun = fn parent_pod_manifest, app_container ->
    %{
      "spec" => %{
        "containers" => [
          %{
            # Copy env vars and resources from the parent container definition.
            # For fields that you don't want to copy, you can specify the desired
            # values here.
            "env" => app_container["env"] || [],
            "envFrom" => app_container["envFrom"] || [],
            "resources" => app_container["resources"] || %{}
          }
        ]
      }
    }
  end

{FLAME.Pool,
  name: MyApp.SamplePool,
  backend: {FLAMEK8sBackend, manifest: manifest_fun}}
