How to rollout new revisions

With the new infrastructure, there will also be more automation with rolling out changes.

This will only apply to changes to the compositions. Anything else like Crossplane itself will still affect all instances at once and should be done by disabling ArgoCD first.

Update instances

These instructions will update by plans. It will update all services that match the plan. So xsmall would update all MariaDB and Redis instances that have that plan.

Control Cluster: get list of all plans

# Standard
kubectl get compositions -l service.syn.tools/sla=standard -o=jsonpath='{range .items[*]}{.metadata.labels.service\.syn\.tools/plan}{"\n"}{end}' | sort | uniq

# Premium
kubectl get compositions -l service.syn.tools/sla=premium -o=jsonpath='{range .items[*]}{.metadata.labels.service\.syn\.tools/plan}{"\n"}{end}' | sort | uniq

Then create jobs according to this template to trigger rollouts:
