🤖 Pull request created from `various-fixes` containing PageHead
breadcrumbs and navigation alignment fixes, Umami analytics proxy, and
infrastructure updates.
### Summary of Changes
1. **SOPS Secret Encryption Scope**:
- Configured `encrypted_regex: '^(data|stringData)$'` in `.sops.yaml`.
- Re-encrypted PostgreSQL and Umami secrets so `apiVersion`, `kind`, and
`metadata.name` remain in clean plaintext.
- Prevents Kustomize controller panic on encrypted metadata during Flux
GitOps reconciliation.
2. **Reliable DNS Fallback**:
- Added standard fallback DNS resolvers (`1.1.1.1`, `8.8.8.8`,
`77.88.8.8`) to `03-cleanup.sh` and `bootstrap-cluster.sh`.
### Summary of Changes
- Configured `/etc/cloud/ds-identify.cfg` with `policy: enabled` so
Debian's `ds-identify` generator never disables cloud-init.
- Installed `isc-dhcp-client` package.
- Explicitly enabled all 4 cloud-init systemd services in base system.
- Cleaned cloud-init seed and removed any disable flags in image
cleanup.
### Summary of Changes
1. **Systemd-Networkd DHCP & Base System**:
- Added `/etc/systemd/network/10-eth.network` with `Name=eth* en*` and
`DHCP=yes`.
- Enabled `systemd-networkd` and `systemd-resolved` so all ethernet
interfaces get DHCP automatically on first boot.
- Added `git` package to base image.
2. **Flux v2 Standalone Installation**:
- Replaced `kubectl apply -k` with standalone `kubectl apply -f
https://github.com/fluxcd/flux2/releases/download/v2.4.0/install.yaml`
so Flux installs in 2 seconds without git dependencies.
3. **Kubectl Access for Non-Root Users**:
- Copies `/etc/rancher/k3s/k3s.yaml` into `/home/<user>/.kube/config`
with `0600` permissions and proper user ownership.
4. **Cluster Kustomization Cleanliness**:
- Removed self-referential `- flux-system` from
`ci/k8s/clusters/production/kustomization.yaml`.
### Summary of Changes
- Added `OpenStack` and `Ec2` to cloud-init `datasource_list` so
cloud-init properly receives Yandex Cloud `user-data` metadata on
instance boot.
- Added serial console autologin drop-in
(`/etc/systemd/system/serial-getty@ttyS0.service.d/autologin.conf`) so
the Serial Console in the Cloud Web Console provides passwordless root
access for emergency recovery.
### Summary of Changes
- Added systemd drop-in override
`/etc/systemd/system/ssh.service.d/10-generate-host-keys.conf` with
`ExecStartPre=-/usr/bin/ssh-keygen -A` so `ssh.service` auto-generates
host keys if missing on startup.
- Added `ssh-keygen -A` to `03-cleanup.sh` and `bootstrap-cluster.sh` in
`user-data.template.yaml`.
### Summary of Changes
This PR incorporates the final infrastructure optimizations following
the initial merge of PR #25:
1. **SOPS & Secrets Management**:
- Generated dedicated Age keypair
(`age1jpa7hqyzzdfq7lvnw3l8qy6648mtjgpcqnljl5jz92dcqjrnsqfsn7m0fl`) and
updated `.sops.yaml`.
- Added SOPS-encrypted production secrets for PostgreSQL
(`ci/k8s/apps/postgres/secret.sops.yaml`) and Umami Analytics
(`ci/k8s/apps/umami/secret.sops.yaml`).
- Verified 100% clean round-trip decryption.
2. **Cloud-Init Template & Git Safety**:
- Converted `user-data.yaml` into `user-data.template.yaml` with clear
stubs for public SSH keys and private Age keys.
- Added `ci/cloud-init/user-data.yaml` to `.gitignore` to prevent
accidental secret leaks.
3. **Persistent Secondary Storage**:
- Added automated detection, ext4 formatting, and mounting of secondary
persistent disk (`/dev/vdb`) to `/var/lib/rancher/k3s/storage` with
`noatime` in `user-data.template.yaml`.
4. **Golden Image Naming & Workflows**:
- Updated image naming convention to include hyphenated UTC timestamps:
`com-ermnvldmr-debian-12-k3s-amd64-YYYY-MM-DD-HH-MM-SS-sha-<short_sha>.qcow2`.
- Verified successful CI golden image build and S3 upload.
