The Ansible Tour, Part 4: Nextcloud – Collabora, Push, Host Database and occ, Role by Role

Mon, 19 Oct 2026 15:52:20 +0200

Part 4 of the Ansible Tour. After the blog in part 3, here comes the second application: Nextcloud. The series describes release v3.3.0, with later changes added as updates. What matches the blog is only mentioned briefly; the focus is on what is different.

Nextcloud is a file cloud: files, calendars, contacts, team folders and – with Collabora – documents edited together in the browser. Two of the three servers run it, for groups of very different size, with the same code and different values in the inventory. The work is shared by next_mariadb and next_redis (database and cache on the host), next_k3s_deploy (Nextcloud, Collabora and the push service as Kubernetes objects), next_config (Nextcloud’s settings) and nextcloud_verify, plus the update playbook.

Bare Metal to K3s: A Nextcloud Migration Battle Log

Today I moved a production Nextcloud from a cozy native bare-metal install to a shiny K3s/container stack. On paper: pull a backup, restore it, flip DNS, done. In practice: a series of small landmines, each invisible until you step on it. Here’s the battle log. 🪖

Step 1: shovel the data 🚚

The heavy lifting was an rsync of ~360 GB of user data plus a ~330 MB SQL dump from the backup box into the new node. Because I pre-synced earlier in the day, the final run only shipped the delta — the whole thing came down to a fast incremental copy. Lesson old as time: pre-seed, then the cutover sync is tiny.
