I have a Windows docker container for running an Azure function app in node.js, so the last line in the Dockerfile is "CMD npm start". However, my app requires that a specific executable be running in the container as well. Right now I have a function in my function app that starts the executable when called, but I need it to start automatically as part of the container starting up. Because this is a function app, there is no single entry point where I can call my start function before anything else, so I need to find a way to start the executable in the Dockerfile itself.
The CMD of a Dockerfile will let me launch an executable OR run "npm start", but not both, so I'm trying to find another way to launch the executable.
When launching the exe in a command console locally the prompt shows up again right away for the next command, so I assumed I could just do this:
RUN ProgramName.exe
CMD npm start
or
CMD ProgramName.exe && npm start
But when I do this, the command hangs indefinitely and I have no idea why.
Does anyone know how I can automatically start the exe running in my container without using the CMD or ENTRYPOINT for it?
You need to get the program to run in the background somehow. If it were a Linux container, I'd know how to. But with Windows, I don't.
Maybe use the start command? https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/start
