Upgrading an application#
Release a new version of the application by pushing an image with the new version tag to whichever Docker repository is used. For more recent applications, this image should be built and pushed as a GitHub action upon release of a new version.
- There are multiple possibilities that depend on the sort of application you have.
If it is a first-party application such as
cachemachine
, with its chart directly in Phalanx, then it should use the recommended pattern of determining the default Docker tag via theappVersion
chart metadata. This will only require updatingappVersion
inChart.yaml
.If, like
cert-manager
, it’s a third-party application with some extra resources glued in, and you are updating to a newer version of the third-party Helm chart, you will need to update theversion
in the dependency.If it is a complex application such as
sasquatch
that bundles first- and third-party applications, you may need to do both, or indeed descend into thecharts
directory and update theappVersion
of the subcharts therein. Tricky cases such as these may require some study before deciding on the best course of action.
Once you have updated the application, Argo CD will that the change is pending, but no changes will be applied automatically. To apply the changes in a given environment, see Syncing Argo CD in an environment.
