Which tag to pull

[adm2k]

Hello Arthur,

Sorry if I am missing something here but, which of these do I want to use for installing V4 Beta?

Thanks, al

Both 'tags' refer to the same 'image'. You can check this by seeing that the long digest number is the same under both tags.

When a new image gets pushed it would have a different digest number and new tag, such as v0.4.0.1_beta but a dev will map the 'latest_beta' tag (or more commonly 'latest' tag) to the new image. This means when people update manually or automatically using containers such as watchtower they always get the latest image available.

By leaving the old images available, still with their unique tag, a user can regress back to a previous version if they encounter problems by pulling a specific rather than generic tag.

Sometimes you will see a project use a three tag system such as 'stable', 'dev' and 'nightly' which equate to the main, normal version, a beta version and a rough, potentially unstable alpha version.

I hope this helps.

Thank you for the detailed explanation, as always I have learned something new! I will be installing this over the weekend.
