How to deploy a change

Main article: Kubernetes/Deployments

Deploying a function-orchestrator change

1. Create and merge change into the deployment-charts repo for the function-orchestrator service.
2. Log in to a deployment server and go to /srv/deployment-charts/helmfile.d/services/function-orchestrator (wait for the every-60-seconds cron to update the /srv/deployment-charts directory with the contents from git if needed).
3. Execute helmfile -e staging -i apply, which will test the patch in staging (see the k8s clusters docs)
4. If successful, helmfile -e wikikube -i apply for actual production traffic.

Deploying a function-evaluator change

1. Create and merge change into the deployment-charts repo for the function-evaluator service.
2. Log in to a deployment server and go to /srv/deployment-charts/helmfile.d/services/function-evaluator (wait for the every-60-seconds cron to update the /srv/deployment-charts directory with the contents from git if needed).
