Deploying to production

As an example, these are the instructions for restoring the production deployment on https://okd.hbp.eu/.

  1. You can use the deployment configuration saved in openshift-prod-export.yaml provided in the repository as a starting point. Edit the route contained in this file to use the correct URL.
  2. Create the project named voluba-linear-backend on https://okd.hbp.eu/
  3. Log in using the command-line oc tool (https://okd.hbp.eu/console/command-line), switch to the voluba-linear-backend project with oc project voluba-linear-backend
  4. Import the objects from your edited YAML file using oc create -f openshift-prod-export.yaml
  5. Re-create the Persistent Volume Claims and upload the data (none for this project).
  6. Edit the Config Maps if needed, re-create the needed Secrets (namely github-webhook-secret).
  7. Start the build. The deployment should follow automatically.
  8. For production, increase the number of replicas in order to be more resilient to node failures: go to Applications -> Deployments -> flask -> Configuration and change the number of Replicas to 3.
  9. Go to Builds -> Builds -> flask -> Configuration, copy the GitHub Webhook URL and configure it into the GitHub repository (https://github.com/HumanBrainProject/voluba-linear-backend/settings/hooks). Make sure to set the Content Type to application/json.

The deployment configuration is saved to openshift-prod-export.yaml by running oc get -o yaml --export is,bc,dc,svc,route,pvc,cm,horizontalpodautoscaler > openshift-prod-export.yaml (status, resourceVersion, generation, @sha256, PersistentVolumeClaim metadata (volumeName, finalizers, annotations) and secret information is stripped manually, see https://collab.humanbrainproject.eu/#/collab/38996/nav/270508 for other edits that may be necessary).
