How to find whether a image is present in the docker repository

Trying to pull a docker image in my local repo. Command used:

docker pull buzybox:1.24
Error response from daemon: repository buzybox not found: does not exist or no pull access

My questions:

1:How to find the repository name which am connected with?

2.Whats the access issue in the error its talking about? Do we also have any kind of access issues in the default repo?? How to find that out?

3.How to change the repo if in case i dont find a image in my currect repo.

4.Do we have any web portal from where we can search if the image is present in repository.

Solution

    1. You do not connect to a repository. You connect to a registry. You are probably connected to https://index.docker.io/v1/ but to be sure, you can run sudo docker info and look for the registry line. The repository in your case is buzybox and you are trying to download the image with tag 1.24 from that repository.

    2. The access issue is probably that you mispelled busybox (notice the 's' instead of a 'z').

    3. To log into a different registry, then run

      docker login https://<YOUR-DOMAIN>:8080

      and then make sure to specify the new registry when you download an image like so:

      docker pull <YOUR-DOMAIN>:8080/busybox:1.24
