Adds a per-entry storage helm chart that owns the PVC and (when host_path is set) the PV, and three triggers for the storage plugin to drive: storage-create installs/upgrades the chart with storage-class existence validation, storage-destroy uninstalls it, storage-status reports the PVC phase. App deployment and cron-job charts now consume storage-app-mounts and reference each PVC by name; the // todo: implement volumes blocks are gone. ProcessVolume gained sub_path, read_only, and persistent_claim fields and the deployment/cron-job templates render them.
Bundling these Secrets in the app helm chart caused two bugs in the scheduler-k3s plugin: a chart rollback could delete Secrets that older ReplicaSets still referenced by exact timestamped name (`env-{app}.{ts}` and `ims-{app}.{ts}`), hard-crashing pods until manual intervention; and the strategic-merge `patchMergeKey` on `imagePullSecrets` let stale entries leak into the live Deployment until the list pointed at many nonexistent Secrets. Each Secret now lives in its own helm release with a stable name (`config-{app}` and `pull-secret-{app}`), installed before the app chart on every deploy. The deployment trigger also prunes any leaked `imagePullSecrets` entries from the live Deployment so the next deploy lands on a clean list, and the rename and destroy paths uninstall the new releases (and the previously-leaked TLS release on rename) under the old app name.
Domains cannot be reused across ingress objects, and port maps are a function of a domain, so the inversion here makes most sense (at the cost of some downtime when migrating.
While this will now more or less require a local docker login - which can be overridden by setting the image-pull-secrets property - this ensures every deploy has a valid context.
One annoying thing is that the secret is per-app vs global, meaning that if the secret must be rotated, all apps need to be redeployed. A future change can fix that by deploying a global secret, or if folks really desire, this can be done by setting the image-pull-secrets property on the app/globally.
The previous mechanism of constructing the helm chart was pretty obnoxious due to needing to have some things in the object and some in template files that were appended afterwards. This change simplifies that by using template files per type with minimal replacements.
The cron id is too long to store in the cronjob, so we generate a short identifier and look that up each time on deploy to ensure stability across time.
This utilizes a Kubernetes Job to start a pod in order to take advantage of completed Job cleanup in Kubernetes. It also properly handles interactivity by ensuring the container has a TTY.
Note that there is currently no provision for parsing docker arguments and translating them into their Kubernetes equivalents.
