Artifactory as docker Registry - docker-remote-cache stays empty

i finally managed to get Artifactory 5.1 running as a docker Registry with nginx in front as Reverse Proxy using the subdomain method with a wildcard SSL certificate.

I have the predefinded set of docker repositories configured: docker-local - repo docker-remote - remote-repo docker - virtual repo

I'm able to login with docker cli and i also can push and pull images to and from docker. as mentioned in JFrog Docs.

I think my "docker-remote" doesn't work - it stays at 0 byte with 0 artifacts in it.

If i pull something that isn't in my local repo i would have guessed that it is pulled from docker.io and cached in docker-remote but it seems its simply pulled from docker.io - thats it.

Do i have to configure something? Did i miss something or do i have to configure Replication ?

Any suggestions ?

Solution

  • To configure your Docker CLI to use Artifactory as its registry, follow the instructions here. Make sure to perform the steps listed under "Configuring Your Docker Client".

    There are a couple of things you can do to check whether you docker CLI is using Artifactory as its registry:

    • Use the docker info command to see what registry is configured
    • Look at the Artifactory request and access logs and look for requests from the Docker CLI
    • Images fetched from docker.io should be present in the remote repository
    • Make sure the images you are pulling are not stored in the local Docker cache
