Yep , which is the difference between

pulumi/actions

and

pulumi/pulumi

both are in dockerhub , looks like both are oficial https://hub.docker.com/r/pulumi/actions and https://hub.docker.com/r/pulumi/pulumi , no description into the images, i'm using them (just for poc) , and pulumi inside is a little bit old.

The

pulumi/actions

image is meant for use with GitHub Actions (more info here https://pulumi.io/reference/cd-github-actions.html). As such, it adds a bit of CI scaffolding, like supporting multiple branches, on top of an installation of the Pulumi SDK and various clouds. The

pulumi/pulumi

image is a simpler, built-from-source, wrapper around the CLI. It's just meant to make it easier to use the CLI in scenarios where you don't want to install it, or for derived images in CI scenarios. We plan to revisit some of the duplication here as part of https://github.com/pulumi/pulumi/issues/1991; though they may remain distinct, we will be sure to clarify their purposes in our docs and descriptions.
