How to Handle Linux Scripts with Docker Desktop on Windows?
Asked by

Hey everyone! I recently got Docker Desktop installed on my Windows machine and started experimenting with it. I cloned a project and ran into a problem: the Docker image kept failing because of the `entrypoint.sh` script. Even though I was mounting it from the repository during runtime, Linux wasn't recognizing it as executable. I found out that this was due to CRLF line endings. I know there's a way to configure Git to handle this automatically on both Windows and Linux, but I'm curious if there are other approaches. How do you all usually manage Docker Desktop on Windows? Any tips would be appreciated! Thanks!

One good practice is to use a text editor that understands Unix-style line endings to avoid these issues. For instance, avoid the default Notepad; instead, try Notepad++ or similar. Familiarize yourself with the end-of-line conversion settings to ensure you don’t accidentally save Unix files with CRLF endings. Alternatively, if you're open to it, using Docker with WSL can save you some hassle since you won’t even need Docker Desktop.

Using WSL along with Docker Engine and Dev Containers is what I find works best. Makes everything seamless!

I exclusively use WSL. This way, everything operates in a true Linux environment. If you want to use a graphical editor, VSCode has remote capabilities that work great with WSL!
CodeAdventurer55: Yeah, it seems like WSL is getting pretty popular for this. Appreciate the insight!

You can also run the command `chmod 755 entrypoint.sh && sed -i 's:rn$:n:' entrypoint.sh` to fix the line endings while making it executable.

Be careful with the text editor you choose; if it doesn't respect Linux line endings, you'll still have issues. Alternatively, you could use something like Nano to create your script first, then just save it properly in a compatible editor.
