Task Domains ​

A task domain is a prefix that allows abbreviating step image names. This has not only the benefit of allowing you to type your pipeline step image names faster, it also allows you to quickly swap out your Docker registry without the need of individually updating all of your pipeline definitions.

Configure task domains with the REEVE_PLUGIN_<plugin name>_TASK_DOMAINS environment variable. The value of this variable should be a space separated list of <domain>:<prefix> pairs. To setup task domains for all available plugins, use the REEVE_SHARED_TASK_DOMAINS environment variable.

The following configures a reeve domain for the official Reeve pipeline steps and a trusted domain docker for the official Docker related Reeve steps.

yaml
services:
  reeve:
    # ...
    environment:
      REEVE_SHARED_TASK_DOMAINS: "docker:reeveci/step-docker- reeve:reeveci/step-"
      REEVE_SHARED_TRUSTED_DOMAINS: "docker"

With this configuration, update your pipeline definitions to look like the following.

yaml
steps:
  - name: NPM
    task: "@reeve/npm-cli" # instead of reeveci/step-npm-cli
    # ...

  - name: Docker
    task: "@docker/deploy" # instead of reeveci/step-docker-deploy
    # ...
