The moves of registry.ci.dev, opam-repo-ci, and get.dune.build have followed the template of OCaml-CI. Notable differences have been that I have hosted get.dune.build in a VM, as the services required very little disk space or CPU/RAM. For opam-repo-ci, the rsync was pretty slow, so I tried running multiple instances using GNU parallel with marginal gains.
cd /var/lib/docker/volumes2/opam-repo-ci_data/_data/var/job
ls -d * | parallel -j 5 rsync -azh c2-4.equinix.ci.dev:/var/lib/docker/volumes/opam-repo-ci_data/_data/var/job/{}/ {}/
The Ansible configuration script for OCaml-CI is misnamed as it configures the machine and deploys infrastructure: Caddy, Grafana, Prometheus and Docker secrets, but not the Docker stack. The Docker stack for OCaml-CI is deployed by make deploy-stack from ocurrent/ocaml-ci. Conversely, opam-repo-ci is deployed from the Ansible playbook, but there is a Makefile and an outdated stack.yml in ocurrent/opam-repo-ci.
As part of the migration away from Equinix, these services have been merged into a single large machine chives.caelum.ci.dev. With this change, I have moved the Docker stack configuration for opam-repo-ci back to the repository PR#428 and merged and renamed the machine configuration PR#44.
We want to thank Equinix for supporting OCaml over the years.
