Newbie! Simple problem

I am playing with the trainsign application to learn more about Balena. I followed all the instructions and have my Raspberry Pi running the app.

However, the container can’t find the shell script to start.

main /bin/sh: 1: ./balena-run.sh: not found

It just keeps showing this error repeatedly. I can’t ssh into the MAIN app, the said the container is restarting.

How can I troubleshoot this?

Thanks!

I’d first try setting an absolute path to your balena-run.sh file. Assuming this is the repo you’re playing with https://github.com/balena-io-playground/UK-Train-Departure-Display the absolute file path would be /usr/app/balena-run.sh.

Another option is specifically invoking bash at the end of your dockerfile with CMD ["bash", "/usr/app/balena-run.sh"]

Hopefully one of those will get you on the right path.

That was great info. That definitely fixed that problem. Thanks!

Now, I am getting syntax errors in the balena-run.sh script.
02.09.19 07:38:11 (-0400) main /usr/app/balena-run.sh: line 2: $‘\r’: command not found
02.09.19 07:38:11 (-0400) main /usr/app/balena-run.sh: line 15: syntax error: unexpected end of file

I will keep working on it. This definitely gets me closer!

So, for some reason, when I push the app, it is adding ^M to the end of each line of the file. This is causing syntax errors I believe. I am sure this is some kind of windows translation issue. I am going to to push from Linux and see if that works differently.

Hi Kurt, if you’re fighting with Line Endings in Git, then this page may be helpful.

So, I gave up on Windows and created a Debian 9 Virtualbox. Pushed the app from Linux and everything worked great. I will do everything in Linux from now on.

Hi Kurt,
