Per https://quay.io/repository/phpseclib/php8.1 I should be able to pull down that Docker container by doing docker pull quay.io/phpseclib/php8.1
but when I try I get this error:
Using default tag: latest
Error response from daemon: manifest for quay.io/phpseclib/php8.1:latest not found: manifest unknown: manifest unknown
Any ideas?
In the case of Quay the issue was that the "latest" tag didn't exist. The git repo I was pulling from didn't have a latest tag but it had an 8.1 tag so if I didn't want to use a custom tagging template I could do this:
Using a custom tagging template is another approach. Just type in latest into the "Enter a tag template" text field and then click the "Add Tag Template" button.
