Upgrading Workflow
2 minute read
This upgrade process requires:
- Helm version 2.1.0 or newer
- Configured Off-Cluster Storage
Upgrade Process
!!! note If upgrading from a Helm Classic install, you’ll need to ‘migrate’ the cluster to a Kubernetes Helm installation. See Workflow-Migration for steps.
Step 1: Apply the Workflow upgrade
Helm will remove all components from the previous release. Traffic to applications deployed through Workflow will continue to flow during the upgrade. No service interruptions should occur.
If Workflow is not configured to use off-cluster Postgres, the Workflow API will experience a brief period of downtime while the database recovers from backup.
First, find the name of the release helm gave to your deployment with helm ls
, then run
$ helm upgrade <release-name> oci://registry.drycc.cc/charts/workflow
Note: If using off-cluster object storage on gcs and/or off-cluster registry using gcr and intending to upgrade from a pre-v2.10.0
chart to v2.10.0
or greater, the key_json
values will now need to be pre-base64-encoded. Therefore, assuming the rest of the custom/off-cluster values are defined in the existing values.yaml
used for previous installs, the following may be run:
$ B64_KEY_JSON="$(cat ~/path/to/key.json | base64 -w 0)"
$ helm upgrade <release_name> drycc/workflow -f values.yaml --set gcs.key_json="${B64_KEY_JSON}",registry-token-refresher.gcr.key_json="${B64_KEY_JSON}"
Alternatively, simply replace the appropriate values in values.yaml and do without the --set
parameter. Make sure to wrap it in single quotes as double quotes will give a parser error when
upgrading.
Step 2: Verify Upgrade
Verify that all components have started and passed their readiness checks:
$ kubectl --namespace=drycc get pods

Step 3: Upgrade the Drycc Client
Users of Drycc Workflow should now upgrade their drycc client to avoid getting WARNING: Client and server API versions do not match. Please consider upgrading.
