[bug] conan docker containers fail to install packages #10824

Open gnzlbg opened 2 years ago

gnzlbg commented 2 years ago

To reproduce:

docker run -it -u $(id -u):$(id -g) -v $(pwd):/src -w /src conanio/gcc72:latest bash -c "conan install catch2"

errors with

ERROR: Can't write version file in '/.conan/version.txt': The folder /.conan does not exist and could not be created (Permission denied).

I don't expect this to error.

Most applications have their own docker containers. To use conan, one needs to install and setup conan within those containers.

It would be super helpful to document somewhere how to install conan into an already existing container and how to set it up for development.

In our own containers, I'm seeing errors of the form:

I think this is not a Conan issue per se, but some docker configuration. What do you think @uilianries?

Maybe move it to conan-docker-tools repo?
