[ https://ovirt-jira.atlassian.net/browse/OVIRT-848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=23315#comment-23315 ] Barak Korren commented on OVIRT-848: ------------------------------------ Some details and considerations about the interaction between containers (specifically Docker-based) and "Standard CI": There are two possible ways to use Docker from inside mock: # Install Docker inside the mock environment, and start up the Docker daemon inside it as well. # Install Docker on the slave VM (The host under mock), Docker client in the mock env, and bind-mount the docket socket ({{/var/run/docker.sock}}) into it. The obvious benefit of method #1 is that it does not require any adjustments to the existing CI infrastructure (We just need to teach devs how to implement it). I have doubts, however, that mock will not cause some difficulties with this (For example, are cgroups mounted inside mock?). We will need to test this and verify it works. Method #1 will also cause issues when we come around to implementing something like OVIRT-873 ([Nested Docker is possible but far from recommneded|https://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/]) or do anything that causes us to run Docker on the hosts themselves. Method #2 will not have the same issues as method #1, but it will require us to distribute and maintain Docker on the slaves which is a step back to the pre-Standard-CI era. I think we should actually implement _both_ methods like this: # Try to mount the Docker socket into the mock env. # If it works use method #2 # If it doesn't, use method #1. This will require a little change to {{mock_runner.sh}} to allow bind mounts to be optional, but this change may provide other benefits so we may as well go for it.

Add support for building containers in oVirt CI -----------------------------------------------

Key: OVIRT-848 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-848 Project: oVirt - virtualization made easy Issue Type: Improvement Reporter: eyal edri [Administrator] Assignee: infra

more and more projects in oVirt are starting to build containers and using Docker files in their reops. We need to start preparing oVirt CI to know how to handle containers and support containers the same way we support rpms today. This will be a parent task with multiple sub-tasks that will follow, the following is a draft list of what we might need to do to add this support: # Install Registry server ( maybe use openshift.ovirt.org ) # Add for standard CI 'build-containers.sh' support # Add verification steps for the build before publishing to registry # Look at 3rd party OSS projects that might help and integrate with existing solutions
