Skill · artefacts · Run an artefact repository

Serve container images from your own repository, including a cache of a public registry

Put an image registry into service on your own repository, with token authentication on Pulp, a connector on a dedicated port and the token realm on Nexus, then the pull-through cache of a public registry. Prove the service by removing the image from the local cache before pulling it, and know that a port the container does not publish returns no code at all.

Beyond the lessons

Assess, practise, pass the proof

Reading a lesson confirms nothing. A skill is confirmed by a passed quiz, practised in a guided lab, and put to the test by a challenge or a mission; an imported lab result is not verified by the site.

Assess yourself

2 quizzes

At the end of the lessons: passed at 70%, they confirm the skill.

Practice

2 guided labs

• Host a container registry on Nexus, port and realm included
• Serve container images, and prove they come from your registry

Proof

No proof

A practical proof is a challenge, a capstone or a declared lab.

Used by the mission “Run a trusted artefact repository”, which has its proof.
