Since the official Jenkins agent image does not include the tools we need—such as Helm, kubectl, curl, and ArgoCD—during Jenkins builds, we must integrate these tools ourselves.

Note: The official image names have changed:

  • jenkins/agent (formerly jenkins/slave) — renamed starting from version 4.3-2
  • jenkins/inbound-agent (formerly jenkins/jnlp-slave) — renamed starting from version 4.3-2
