# One-shot deployment of the forgejo.viktorbarzin.me containerd hosts.toml
|

|
|
# entry across every k8s node. Cloud-init only fires on VM provision, so
|
||
|
|
# existing nodes need this manual rollout.
|
||
|
|
#
|
||
|
|
# What it does, per node:
|
||
|
|
# 1. drain (ignore-daemonsets, delete-emptydir-data)
|
||
|
|
# 2. ssh in: mkdir + write /etc/containerd/certs.d/forgejo.viktorbarzin.me/hosts.toml
|
||
|
|
# 3. systemctl restart containerd
|
||
|
|
# 4. uncordon
|
||
|
|
#
|
||
|
|
# hosts.toml is documented as hot-reloaded but the post-2026-04-19
|
||
|
|
# containerd corruption playbook calls for an explicit restart so the
|
||
|
|
# config is unambiguously in effect. Running drain/uncordon around it
|
||
|
|
# avoids pulling against an in-flight containerd restart.
|
||
|
|
#
|
||
|
|
# Re-run is safe: writes are idempotent.
