Cron containers were never reaped once they exceeded their active deadline, so a hung cron task ran indefinitely instead of being retired after 24 hours as documented. `cron:run` now also accepts a `--ttl-seconds` argument, matching the one `dokku run` already takes.
Kubernetes pulls the app image itself, so a k3s host is free to reap its local copy while the workload keeps running, which the `registry` plugin already does on its own. Deploys, restarts, `dokku run`, and in-cluster cron no longer assert that the image is present locally, falling back to the metadata recorded in the app's current Helm release. A `ps:restart` naming a single process type now rolls only that process type's pods rather than silently redeploying every one. Apps with an `app.json` postdeploy task still require the image locally, as that task runs on the Dokku host.
Releases 0.38.0 through 0.38.25 recorded the ENV file migration and deliberately left the file at the old path, so 0.38.26 treating a leftover file as a hand-edit replayed the environment as it stood at that upgrade over every `config:set` and `config:unset` made since, reinstating variables and secrets that had been deliberately unset. A file found at the old path once its migration is on record is no longer imported: it is removed when it agrees with the current config, and is otherwise moved aside to `ENV.migrated` with the keys it disagrees on named in a warning. That warning now reaches the operator during an upgrade rather than being swallowed, which is why the overwrite went unreported.
Install steps run in alphabetical order of the enabled plugin directory, so `apps`, `builder`, and `checks` read an app's environment before the `config` plugin had moved the `ENV` file to its new location. The read came back empty, so their deprecated `DOKKU_*` variables were never migrated to the matching plugin property and were never unset, with nothing reported either way: `dokku config:show` kept listing the variable while the plugin behaved as though it were unset. The relocation now runs before any deprecated variable is read, whatever the install order, and each old file is removed as soon as it has been drained rather than on a later install, which also covers the global file that was never removed at all. A file that reappears at the old path can only have been written by hand, so it is merged in with a warning naming its keys instead of being discarded.
Host-crontab generation for `app.json` cron tasks now lives in the `cron` plugin, gated by a new `scheduler-uses-host-cron` trigger that the `docker-local` scheduler answers true while self-managed schedulers such as `k3s` answer false. This lets any host-cron scheduler participate in normal `app.json` cron without coupling to `scheduler-docker-local` or duplicating the crontab writer, while the `k3s` scheduler continues to manage its own in-cluster cron jobs.
Closes#8862.
The nginx deploy-time pre-validation runs `nginx -t` against a minimal wrapper that omits the global `load_module` directives, so a custom `nginx.conf.sigil` using a directive from a dynamically loaded module fails validation even though it is valid against the running server. Document overriding the `validate-config` template through the `nginx-app-template-source` trigger as the supported workaround.
Adds `certs-set` and `certs-remove` plugin triggers so other plugins can install or remove an app's SSL cert/key pair without shelling out to the `dokku certs:add` / `dokku certs:remove` subcommands. Shared implementations live as `fn-certs-set` and `fn-certs-remove` in `plugins/certs/internal-functions`, with the subcommands and the new triggers calling `verify_app_name` before delegating.
Moves the actual exec out of the storage plugin and into a new scheduler-storage-exec plugn trigger. scheduler-docker-local does docker run with TTY-aware -it/-i selection and --user derived from entry.Chown; scheduler-k3s creates a throwaway Pod via the kubernetes API, waits for it to reach Running with structured error reporting (ImagePullBackOff and friends are surfaced from the container status verbatim, no kubectl involvement), execs the user command via the existing SPDY plumbing in k8s.go, and deletes the Pod on the way out. (Entry).Validate now accepts either an absolute path or a docker named-volume token for docker-local entries so the migration synthesizer's named-volume legacy entries work cleanly. storage:exec gains --as-user for one-off uid overrides, propagates the underlying tool's exit code via os.Exit, and detects TTY/interactive mode from os.Stdin so non-interactive scripted use no longer trips over docker's input-device-is-not-a-tty error.
storage:list was calling the storage-list plugn trigger which read -v lines from docker-options. After the install-time migration drains those lines into the attachment store, that source is empty for every migrated app and for any app that only ever used storage:create + storage:mount. The fix moves CommandList to call a new in-process ListAppMountEntries helper that reads attachments directly, surfaces the entry name in JSON output via a new entry_name field, and falls back to the entry name as the host token for k3s entries with no host path so the colon form remains well-formed. The storage-list plugn trigger is kept for back-compat with external callers but emits a deprecation warning and now reads from the same attachment-driven source.
Updates persistent-storage.md to lead with the named storage entry workflow while keeping the legacy colon-form documentation intact, adds a Persistent storage section to the k3s scheduler doc, documents the storage-app-mounts, storage-create, storage-destroy, and storage-status triggers in plugin-triggers, and adds an entry to the 0.38.0 migration guide explaining the install-time migration of legacy mounts and the new DNS-1123 name validation. Bats coverage in tests/unit/storage.bats now exercises storage:create / list-entries / destroy, name validation rejections, multi-entry attachment, the destroy-while-mounted error, and the ensure-directory deprecation warning.
Adds a `--process` flag (repeatable) to docker-options:add/remove/clear/list and the new docker-options:list subcommand for querying a single process+phase pair. Process scoping is supported only for the deploy phase since build runs once per app and run covers ad-hoc commands and cron tasks where no Procfile process type is available. Storage moves from `$DOKKU_ROOT/$APP/DOCKER_OPTIONS_*` files to property lists under `/var/lib/dokku/config/docker-options/$APP/{processType}.{phase}`, with `_default_` as the sentinel for app-wide options. The install trigger migrates pre-existing DOCKER_OPTIONS_* files into property lists once and renames them to `.migrated`; a global marker makes re-runs strictly no-op. The legacy docker-args-{build,deploy,run} bash triggers are reimplemented in Go alongside a new docker-args-process-deploy trigger that surfaces per-process options to the scheduler. The :report command exposes one dynamic flag per configured `process.deploy` pair (e.g. `--docker-options-deploy.web`) and supports `--format json`. There is no `--global` flag; omitting `--process` keeps the historical default behaviour, since `--global` elsewhere in dokku means "across all apps". Closes#2441.
If the scheduler is not docker-local, we will assume that a separate plugin trigger will pull access/error logs on our behalf. For k3s, the naive implementation is to pull logs from a single container (multiple ingress-nginx pods will be supported in a future release).
Closes#7268
Using compose instead of manual docker calls allows folks to customize the vector container by using a custom compose.yml template file. This opens us up to more customizations while aligning container management with how we do other external containers (such as for the proxy plugins).
Refs #5784
This change converts existing CHECKS files into a healthchecks key that is understood by 'docker-container-healthchecker'. This tool supports a number of different types of container healthchecks - command, http, uptime - and can perform healthchecks against non-web processes.
The use of the old CHECKS file is now deprecated, and will be removed in the next minor version. Users can use the 'docker-container-healthchecker' to convert existing CHECKS files to the new format automatically.
Closes#2760
This plugin is mostly compatible with the nginx plugin, but runs the proxy within a docker container. Users do not have direct access to add custom openresty configuration at this time, but instead receive the ability to setup automatic ssl on first request via letsencrypt integration.
Previously, we would always set the port mapping during a dockerfile build, making it difficult for users to override mappings. We also only _sometimes_ updated the detected port mapping, further confusing issues when users were migrating from Dockerfile to Buildpacks for builds.
Now, we always detect the port mapping during the build process, and only use that detected port mapping if an override is not specified. This greatly simplifies the experience around port mapping, as now a user can create an app, set a port mapping, and that first deploy will respect the port mapping without an additional deploy.
The builder always has the best context for what the app should be listening on, and thus we can always specify a "default" port mapping at this stage. Users can override this map as desired later.
This change also results in the removal of a ton of internal code that is now centralized in the ports plugin.
Closes#4067
During an app build, we now auto-detect ports based on the source code. This is usually http:80:5000, with Dockerfile-based deploys having their ports extracted from the docker image or Dockerfile. Additionally, we add an https:443 mapping for any detected http:80 mapping when there is an ssl certificate, and all http port mappings are transformed to https mappings for Dockerfile-based deploys.
While the ports aren't currently consumed, a future refactor will provide the ability to fallback to the new detected ports when there is no user-specified port mapping.
This ensures users don't have issues with cached state in regards to files pulled from the repo/image.
Also add missing docs for deploy-source-set trigger.
Closes#5963
This allows folks to deploy apps that don't have a web process without needing to scale that process down before/after the first deploy. Note that the formations key in the app.json or a manual scale of other processes will be necessary to start anything non-web.
