Description of problem¶

Work to be done on cephadm's Docker in Docker box

1. rootless unprivileged docker (cgroups v2?)
2. Use [letsencrypt SSL certificates](https://letsencrypt.org/) to avoid self-signed certificate issues
3. Replace var-lib-docker volume with side-car registry caching service.
4. Expose cephadm.log to stdout for `dc/docker logs` (might be almost impossible due to systemd PID 1)
5. Create and use separate cluster network
6. Add vstart-runner-like teuthology integration (for running tests)dd time sync
7. Modify ceph-volume to accept loopback devices and it can be used to create more osds.
8. Replace docker with podman and podman-compose https://www.redhat.com/sysadmin/podman-inside-container .
9. Improve flow of scripts. Add more options to skip parts or something like that.
10. If you start a cluster more than one time with the same number of osds it should be easier to call `cephadm ceph-volume lvm zap /dev/vg1/lv{i}` than removing the whole loopback device and recreating it again. This will also improve the start time.
11. Update dependencies of ceph-ci/ceph in order to not have to create a wrapper for the image and trick cephadm. (`./get_ceph_image.sh` creates the wrapper with the same image name but with more deps).
12. Rewrite scripts to python.

Environment¶

• Platform (OS/distro/release):
• Cluster details (nodes, monitors, OSDs):
• Did it happen on a stable environment or after a migration/upgrade?:
• Browser used (e.g.: Version 86.0.4240.198 (Official Build) (64-bit)):
