[JIRA] (OVIRT-2533) multi-stage support in CI slaves

multi-stage support in CI slaves -------------------------------- Key: OVIRT-2533 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2533 Project: oVirt - virtualization made easy Issue Type: Improvement Reporter: Roy Golan Assignee: infra I would like to get multi-stage support upstream. Our default docker packages for centos 7.5 is 1.13. For multi-stage support we need > 1.17 or have buildah working in mock (preferable over docker, won't happen now I guess?). Using this method[1] to install docker-ce I was able to get 1.18 running. Doable? Regards, Roy [1] https://docs.docker.com/install/linux/docker-ce/centos/
