Previously backups were created even if no service upgrades were
executed. To allow this some things are restructured:
* new chartInfo type that holds release name, path and chart name
* upgrade execution and version validity are checked separately
Previously the chart's values were not set, relying on the
values that are already present in the cluster and reusing
those. This does not work as e.g. the image values
are only set while loading the charts. Also, the templates
are not rendered correctly without all values set.
These backups could be used in case an upgrade
misbehaves after helm declared it as successful.
The manual backups are required as helm-rollback
won't touch custom resources and changes to CRDs
delete resources of the old version.
Run with: constellation upgrade execute --helm.
This will only upgrade the helm charts. No config is needed.
Upgrades are implemented via helm's upgrade action, i.e. they
automatically roll back if something goes wrong. Releases could
still be managed via helm, even after an upgrade with constellation
has been done.
Currently not user facing as CRD/CR backups are still in progress.
These backups should be automatically created and saved to the
user's disk as updates may delete CRs. This happens implicitly
through CRD upgrades, which are part of microservice upgrades.
