Cross compiling in Docker

Hi,

I have installed the Docker image for cross compiling and built the toolchain which took a few hours. Now I would like to save the container to avoid having to build it all over again.

What is the best approach to do that? I tried committing the container which took forever and then I got a "no space left" error. I am pretty sure this is not the appropriate way of doing it.

Any help is appreciated

@Erik-Hougaard isn’t the container saved unless you delete it? I built the toolchain and images here under docker on macOS and just start the container when I need access to it.

Are you running out of space on your local drive? The build is huge here, like 10gb or something.

@Erik-Hougaard
I'm no docker expert, but I've been learning a bit about it over the last few days. When you exit a container it automatically maintains its last state.

I would suggest that you review the docker docs on how to re-use a container. i.e. look into docker start or docker attach if you detached instead of exiting.
