v1-v2 Migration¶

The following migrations must be done when moving from v1 to v2 docs.

Chart¶

change	migration
`chart_name` removed	Remove. It was redundant with `metadata.name` while at the same time not guaranteeing uniqueness. Log messages now reference `metadata.name` for improved grep-ability.
`test` as a boolean removed	test must now be an object.
`timeout` removed	Use `wait.timeout` instead.
`install` removed	Remove. Previously unused.
`upgrade.post` removed	Remove.
`upgrade.pre.update` removed	Remove.
`upgrade.pre.create` removed	Remove.
`upgrade.pre.delete[*].name` removed	Remove.
`upgrade.pre.delete[*]` with `type: job` no longer deletes cronjobs	If you have an item in `upgrade.pre.delete` and `type: job` and you also want to delete cronjobs, add another item with `type: cronjob` and same labels.
`upgrade.no_hooks` moved to `upgrade.options.no_hooks`, and now optional	Remove as desired, otherwise move to the new location.
`source.subpath` now optional, deafults to no subpath.	Remove as desired.
Template naming for template files aligned with Helm CLI.	If a chart was relying on Armada’s previous misaligned template naming, where it was omitting the `templates/` prefix, such as via `include` argument, that argument will need to be updated. This could also theoretically affect whether the file is ignored, if the old or new name is in `.helmignore` (unlikely). The fixed template names alone will not cause a release to be updated, as the diff logic accounts for this.
`wait` improvements	See Wait Improvements.

Wait Improvements¶

The v2 wait API includes the following changes.

Breaking changes¶

wait.resources now defaults to all supported resource types, currently job, daemonset, statefulset, deployment, and pod, with required (a new option) set to false. The previous default was the equivalent of pods with required=true, and jobs with required=false.
type: pod waits now exclude pods owned by other resources, such as controllers, as one should instead wait directly on the controller itself, which per 1. is now the default.
Waits are no longer retried due to resources having been modified. This was mildly useful before as an indicator of whether all targeted resources were accounted for, but with 1. and 2. above, we are now tracking top-level resources directly included in the release, rather than generated resources, such as controller-owned pods, so there is no need to wait for them to come into existence.
wait.native.enabled is now disabled by default. With the above changes, this is no longer useful as a backup mechanism. Having both enabled leads to ambiguity in which wait would fail in each case. More importantly, this must be disabled in order to use the min_ready functionality, otherwise helm will wait for 100% anyway. So this prevents accidentally leaving it enabled in that case. Also when the helm native wait times out, this caused the release to be marked FAILED by helm, which caused it to be purged and re-installed (unless protected), even though the wait criteria may have eventually succeeded, which is already validated by armada on a retry.

New features¶

Per-resource-type overrides¶

wait.resources can now be a dict, mapping individual resource types to wait configurations (or lists thereof), such that one can keep the default configuration for the other resource types, and also disable a given resource type, by mapping it to false.

The ability to provide the entire explicit list for wait.resources remains in place as well.

required¶

A required field is also exposed for items/values in wait.resources.

allow_async_updates¶

An allow_async_updates field is added to daemonset and statefulset type items/values in wait.resources.

ChartGroup¶

change	migration
`test_charts` removed	Use the Chart schema’s test.enabled instead.

Manifest¶

No changes.
