Invalid reference format error while trying to pull image from docker

The docker pull for the latest image from repository is failing with the error "Invalid reference format". sample-project is the artifactId and the version is 1.0.0-SNAPSHOT

The command is

docker pull https://docker-production.sample/sample-project:latest

Is there any syntax error in the above command?

I tried to pull the docker image from the repository with the latest commit tag, but the pull failed with Invalid reference format error

Solution

  • From documentation.

    By default, docker pull pulls images from Docker Hub. It is also possible to manually specify the path of a registry to pull from. For example, if you have set up a local registry, you can specify its path to pull from it. A registry path is similar to a URL, but does not contain a protocol specifier (https://).

    Doker pull command has to be in the following format.

    docker pull REGISTRY_NAME/IMAGE_NAME:TAG

e.g: docker pull myregistry.local:5000/testing:1.2

    In your case something like the below.

    docker pull docker-production.sample/sample-project:latest
