I have been using Fedora CoreOS version 31.20200505.3.0 on digitalocean (image took from here https://getfedora.org/coreos/download?tab=cloud_operators&stream=stable)
Default user core, but need elevation to use docker
Installing docker-compose via binary with command
curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o ~/bin/docker-compose chmod +x ~/bin/docker-compose
doesn't work due to error: " Error loading Python lib '/tmp/_MEI7CUfMy/libpython3.7m.so.1.0': dlopen: libcrypt.so.1: cannot open shared object file: No such file or directory "
So I tried alternative install via
curl -L --fail https://github.com/docker/compose/releases/download/1.25.5/run.sh -o ~/bin/docker-compose chmod +x ~/bin/docker-compose
(as root) But then was the problem with inaccessible bind mounts. Solved with solution from here https://stackoverflow.com/questions/24288616/permission-denied-on-accessing-host-directory-in-docker (added :Z) to option and modified ~/bin/docker-compose shell script accordingly.
But then I'm getting error "Couldn't connect to Docker daemon at http+docker://localhost - is it running?"
running docker-compose sh and
docker run hello-world I get "docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.40/containers/create: dial unix /var/run/docker.sock: connect: permission denied.
See 'docker run --help'."
At this point I'm considering other container distribution or debian.
Can anyone point out how to install docker-compose on Fedora CoreOS?
Thanks to @Bert hint this solves issue with docker-compose binary
sudo rpm-ostree install libxcrypt-compat
