Is there a way to let Docker list all the available image versions that can be downloaded?
Let's say I want to get the latest version of Apache, then I could type this:
docker pull httpd:latest
Now, if I am interested in a particular version, I could type this:
docker pull httpd:2.4.34
In order to be able to do that though, I need to know that there is a version 2.4.34 available. Now, is there a way to list available versions? I am looking for something similar to this:
docker list httpd versions
and I would like to have a response similar to this:
2.4.34
2.4.32
2.4.29
2.2.34
...
There is an API endpoint for this action which is explained here:
https://docs.docker.com/registry/spec/api/#listing-image-tags
The endpoint itself is the following:
/v1/repositories/(namespace)/(repository)/tags
So you can run the following command in order to access it:
curl -u <username>:<password> https://registry-1.docker.io/v1/repositories/<username>/<image_name>/tags
