Sorry if this is covered by docs couldn’t understand something about wandb jobs (wandb launch);

Basically, does the Dockerfile itself must have an `Entrypoint` attr, which runs a program? Or is it enough to have a docker image which has WANDB\_DOCKER, wandb\_api\_key env variable set, having a python directory codebase which can start wandb runs?? (can’t create a job this way though…), if possible without logging the code.

Cleared:  
Yeah, the Dockerfile should be complete end to end such that just running the docker file should run the program, it must have `Entrypoint` attr in the Dockerfile, which actually can be changed from the overrides when we pass it to queue.

Hi @saishreddyk, great to see you’re using Launch and you found the answer! Just for reference, I’m sharing two links to our docs [here](https://docs.wandb.ai/ref/cli/wandb-launch) and [here](https://docs.wandb.ai/guides/launch) in case they’re useful.
