^{Originally posted by dan-cooke September 30, 2022} I want to tag a docker image using nx affected --target=docker --tags=myrepo.io/{APP}

How can I get the current APP being executed by nx affected. I swore lerna had something for this, but I can’t quite find it.

Any ideas?</div>

Creating an issue because I really don’t see any way of achieving this without creating a custom docker executor, which seems wasteful as there already exists a great community executor.

It would be useful for performing dynamic commands based on the name of the currently affected app

This seems simple enough, we could add NX_PROJECT_NAME as an env variable in the forked process for each executor pretty easily I think ™️…

Implementation of custom executor docker could use executorContext to get project name.
