Azure Docker Container - how to pass startup commands to a docker run?

Question

Faced with this screen, I have managed to easily deploy a rails app to azure, on docker container app service, but logging it is a pain since the only way they have access to logs is through FTP.

Has anyone figured out a good way to running the docker run command inside azure so it essentially accepts any params.

in this case it's trying to simply log to a remote service, if anyone also has other suggestions of retrieving logs except FTP, would massively appreciate.

No, at the time of writing this is not possible, you can only pass in anything that you would normally pass to docker run container:tag %YOUR_STARTUP_COMMAND_WILL_GO_HERE_AS_IS%, so after your container name.

TLDR you cannot pass any startup parameters to Linux WebApp except for the command that needs to be run in the container. Lets say you want to run your container called MYPYTHON using the PROD tag and run some python code, you would do something like this

Startup Command = /usr/bin/python3 /home/code/my_python_entry_point.py

and that would get appended (AT THE VERY END ONLY) to the actual docker command:

docker run -t username/MYPYTHON:PROD /usr/bin/python3 /home/code/my_python_entry_point.py
