I made a new COPR repository for CRUN so that it can be easily tested on Fedora:
To install crun on Fedora, it is enough to:
# dnf install 'dnf-command(copr)' # dnf -y copr enable gscrivano/crun # dnf install -y crun
a recent change in the atomic tool, which didn’t still get into a release, allows to easily override the OCI runtime for system containers. Assuming you are using atomic from the upstream repository, you can use crun as:
# atomic install --system ----runtime /usr/bin/crun registry.fedoraproject.org/f27/etcd # systemctl start etcd
It will install etcd as a system container which runs through crun!
You might need to disable SELinux as the /usr/bin/crun executable is not yet labelled correctly.
