Some helm chart upgrades require side-effects that a plain `helm upgrade` cannot perform, such as deleting deployments whose immutable selectors changed. Charts may now register pre and post upgrade hooks against a target version; applicable hooks fire in ascending semver order, each bracketed around an upgrade to its version, with a final upgrade to the chart's configured version when needed. The new `keda-add-ons-http` 0.12.2 hook deletes the chart-managed deployments before the upgrade so the new selectors take effect cleanly.
Mirrors the JSON output convention already used by scheduler:report, builder:report, network:report, and traefik:report. Both plugins now accept `--format json` to emit a single-line JSON object whose keys are the property names with the plugin prefix stripped. Combining `--format` with an info flag is rejected with an error message that matches the Go-based report helper.
Closes#8499
Adds `git:auth-status HOST [USERNAME] [PASSWORD]` which exits 0 when the
configured `.netrc` entry matches the requested state and 1 otherwise,
allowing external tooling to detect whether `git:auth` would change
anything without reading `$DOKKU_ROOT/.netrc` directly. Both `git:auth`
and `git:auth-status` now also accept the password via `STDIN`.
The buildpacks entry in tests/apps/dockerfile/app.json caused
the post-extract trigger to write a .buildpacks file during
Dockerfile-based deploys, breaking builder detection. Remove
the entry and add Go unit tests for getBuildpacks/validBuildpackURL,
a bats integration test for deploying with app.json buildpacks,
and documentation for the new feature.
Node profiles can be used to specify repetitive options for clusters, making it easier to add specific types of instances quickly.
This PR additionally fixes kubelet-args specification - the same key can be specified multiple times, such as when specifying custom sysctl rules.
If a global vector-sink property on the logs plugin is set, we will use that to configure a log sink (defaulting to console output otherwise). Note that the actual configuration still needs to be a valid DSN representing a Vector log sink.
While this does not support pinning log sinks to specific apps, it opens up integration for those who use a single k3s cluster in shared tenancy.
Some files - those maintained by external organizations - have a very light treatment and solely point to the upstream documentation to reduce any issues creating examples/documentation for them that may differ in the future.
Closes#7315
Dokku ships with default charts and customizes their helm values. In certain cases, it may be useful to further customize those values to better support specific installations. With this change, it is now possible to set custom values by providing the key in the format `chart.$CHART_NAME.$PROPERTY`. For instance, to increase timeouts for the keda http addon:
```shell
dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.tcpConnectTimeout 120s
dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.keepAlive 120s
dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.responseHeaderTimeout 120s
dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.idleConnTimeout 120s
dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.tlsHandshakeTimeout 120s
dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.expectContinueTimeout 120s
```
To reset a value to its default, simply set the value to an empty string.
```shell
dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.tcpConnectTimeout
```
Once the values are set, users will need to then run `scheduler-k3s:ensure-charts` with either the `--force` flag or specify the `--chart` flag with a list of charts to force apply.
```shell
dokku scheduler-k3s:ensure-charts --force
dokku scheduler-k3s:ensure-charts --chart keda-add-ons-http
```
Note that the existing dokku-provided values cannot be removed, but can be overridden.
