cri-o: Wrong PATH for conmon with the cri-o-1.18.1-1.1.el8 package

Description

After installing the cri-o-1.18.1-1.1 the /etc/crio/crio.conf expetecs the conmon binary to be located at /usr/libexec/crio/conmon instead of the /usr/bin/conmon.

Steps to reproduce the issue:

wget https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable:/cri-o:/1.18/CentOS_8/devel:kubic:libcontainers:stable:cri-o:1.18.repo -P /etc/yum.repos.d
dnf install cri-o
systemctl start crio.service

To fix:

sed 's|/usr/libexec/crio/conmon|/usr/bin/conmon|' -i /etc/crio/crio.conf
systemctl start crio.service

Describe the results you received:

– Unit crio.service has begun starting up. May 17 23:07:00 localhost crio[1967]: time=“2020-05-17 23:07:00.078367817-03:00” level=info msg=“Using default capabilities: CAP_CHOWN, CAP_DAC_OVERRIDE, CAP_FSETID, CAP_FOWNER, CAP_SETGID, CAP_SETUID, CAP_SETPCAP, CAP_NET_BIND_SERVICE, CAP_KILL” May 17 23:07:00 localhost crio[1967]: time=“2020-05-17 23:07:00.079441070-03:00” level=fatal msg=“Validating runtime config: conmon validation: invalid conmon path: stat /usr/libexec/crio/conmon: no such file or directory” May 17 23:07:00 localhost systemd[1]: crio.service: Main process exited, code=exited, status=1/FAILURE May 17 23:07:00 localhost systemd[1]: crio.service: Failed with result ‘exit-code’. May 17 23:07:00 localhost systemd[1]: Failed to start Container Runtime Interface for OCI (CRI-O).

Describe the results you expected:

I guess we should update the crio docs to disable container-tools module for centos8 and 8stream. Users can get the deps from the main OBS repo which has conmon/skopeo etc. and container-selinux from a copr repo. So, something like:

sudo dnf -y module disable container-tools
sudo dnf -y install 'dnf-command(copr)'
sudo dnf -y copr enable rhcontainerbot/container-selinux
sudo curl -L -o /etc/yum.repos.d/devel:kubic:libcontainers:stable.repo https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/CentOS_8/devel:kubic:libcontainers:stable.repo

…followed by the regular instructions to add the crio OBS repo and install crio package. Let me know if that works.

@lsm5 @dougsland with the copr enabled and the container-tools disabled, everything looks good

 yum install cri-o
