We need to be able to tag images, it seems that we can do this using curl to download and upload a given manifest to a different location referenced by the tag we want to create. We need to authenticate in curl for this, do we use a Bearer Token? If so, how can we get one, we need an example? Or Do we simply use --user username:password https://… for every request? Do we use the URL to the repo, or the :port value used for docker login (also podman login)? Any help appreciated. I’d like to be able to tag Docker images remotely using Nexus as a registry. Thanks.
I think this article might help you with your action via CURL: https://success.docker.com/article/how-do-i-authenticate-with-the-v2-api
