Procedures and Actions

For orchestrations involving multiple resources and executions, Komodo offers the Procedure and Action resource types.

Procedures

Procedures are compositions of many executions, such as RunBuild and DeployStack. The executions are grouped into a series of Stages, where each Stage contains one or more executions to run all at once. The Procedure will wait until all of the executions in a Stage are complete before moving on to the next stage. In short, the executions in a Stage are run in parallel, and the stages themselves are executed sequentially.

Batch Executions

Many executions have a Batch version you can select, for example BatchDeployStackIfChanged. With this, you can match multiple Stacks by name using wildcard syntax and regex.

TOML Example

Like all Resources, Procedures have a TOML representation, and can be managed in ResourceSyncs.

[[procedure]]
name = "pull-deploy"
description = "Pulls stack-repo, deploys stacks"

[[procedure.config.stage]]
name = "Pull Repo"
executions = [
  { execution.type = "PullRepo", execution.params.pattern = "stack-repo" },
]

[[procedure.config.stage]]
name = "Deploy if changed"
executions = [
  # Uses the Batch version, witch matches many stacks by pattern
  # This one matches all stacks prefixed with `foo-` (wildcard) and `bar-` (regex).
  { execution.type = "BatchDeployStackIfChanged", execution.params.pattern = "foo-* , \\^bar-.*$\\" },
]

Actions

Actions give users the power of Typescript to write calls to the Komodo API.

For example, an Action script like this will align the versions and branches of many Builds.

const VERSION = "1.16.5";
const BRANCH = "dev/" + VERSION;
const APPS = ["core", "periphery"];
const ARCHS = ["x86", "aarch64"];

await komodo.write("UpdateVariableValue", {
  name: "KOMODO_DEV_VERSION",
  value: VERSION,
});
console.log("Updated KOMODO_DEV_VERSION to " + VERSION);

for (const app of APPS) {
  for (const arch of ARCHS) {
    const name = `komodo-${app}-${arch}-dev`;
    await komodo.write("UpdateBuild", {
      id: name,
      config: {
        version: VERSION as any,
        branch: BRANCH,
      },
    });
    console.log(
      `Updated Build ${name} to version ${VERSION} and branch ${BRANCH}`,
    );
  }
}

for (const arch of ARCHS) {
  const name = `periphery-bin-${arch}-dev`;
  await komodo.write("UpdateRepo", {
    id: name,
    config: {
      branch: BRANCH,
    },
  });
  console.log(`Updated Repo ${name} to branch ${BRANCH}`);
}
