Test Actions

Available as the agent.replicante.io/test.* family of identifiers, these actions focus on testing and understanding the agents.

None of these action do much useful work but they can be used to:

• Test and explore the node actions system and connection to the agent.
• Understand how node actions work, execute and impact the agent.
• Provide a a way to write demos and examples that actually run without risk to the node.

Node actions can be scheduled directly through the specification API or through Replicante Core. As a reminder, the is the YAML to apply new node actions to Replicante Core:

apiVersion: replicante.io/v0
kind: NodeAction

metadata:
  # Can override the namespace with --namespace=test-namespace
  namespace: default
  # Can override the cluster with --cluster=test-cluster
  cluster: target-cluster-id
  # Can override the cluster with --node=test-node
  node: target-node-id

spec:
  action: agent.replicante.io/test.${ACTION}
  args: null

Each test action supports different args as detailed below.

Fail

This action always returns an error when executed. Mainly useful to test and explore how errors during action execution are handled.

Any args specified for the action are ignored.

Loop

The action implementation increments a counter (tracked in the execution state) every loop. Once the counter reaches the total count the action succeeds.

The target count to reach can be set with the args.target attribute.

Success

The action succeeds as soon as it is invoked and any args to it are ignored.
