Per review feedback: remove the self-hosted Renovate deployment
(kubernetes/code/renovate/* + root kustomization wiring) from this PR and
defer it to a follow-up. Keep the renovate.json config to merge now.
Also drop the postUpgradeTasks SOPS re-encrypt block: it depended on the
runner's boot.sh decrypt flow, and the hosted Mend app cannot run 'sops'
(allowedPostUpgradeCommands). SOPS handling returns with the deployment.
The prior postUpgradeTasks command 'sops -d ... && sops -e' was wrong:
Renovate has no preUpgradeTasks hook, and postUpgradeTasks runs AFTER
Renovate rewrites the file. These values.yaml are SOPS documents whose
sops.mac authenticates the whole file, so editing a plaintext image.tag
invalidates the MAC and 'sops -d' then fails (data-integrity error). The
claimed decrypt-after-bump therefore could never work.
boot.sh now decrypts every values.yaml in the checkout BEFORE Renovate
extracts/edits them, committing the decrypted tree locally (never pushed,
so no plaintext secrets enter remote git). postUpgradeTasks is reduced to
'sops -e -i' only (the file is already plaintext when Renovate edits it).
Validated: kustomize build passes for the whole kubernetes/ tree.
Address review feedback on SOPS handling for encrypted values.yaml.
- renovate.json: Renovate has NO preUpgradeTasks option (verified against
the renovate-schema). Decrypt must therefore happen inside postUpgradeTasks
(which run after the tag bump, before the commit): decrypt the values.yaml,
then re-encrypt. Encrypting an already-encrypted file would double-encrypt
the existing ENC secret values. Only **/values.yaml is re-encrypted; the
docker-compose and Chart.yaml files are not SOPS-encrypted here.
- kubernetes/code/renovate: self-hosted Renovate runner as a Flux CronJob
running the renovatebot/renovate image, with sops allowed as a
postUpgradeTask command and the SOPS PGP key loaded to re-encrypt
values.yaml. Secrets come from SOPS-encrypted dotenv/env file sources.
- Wire code/renovate into the root kubernetes kustomization.
Drop the generate-renovate.sh generator and explicit fileMatch lists.
Renovate auto-discovers docker-compose, values.yaml and Chart.yaml via
the docker-compose, helm-values and helmv3 managers. Use helmv3 (not
helm-requirements) for Chart.yaml dependencies (Helm v3).
