Manual deployment

Performing deployments manually requires that you have access to the cluster and kubectl configured.

For automated deployments, use NAIS deploy.

$ kubectl apply -f nais.yaml
application.nais.io/<app name> created

Verify that your application is running

$ kubectl get pod -l app=<myapp>
NAME                          READY   STATUS    RESTARTS   AGE
<app name>-59cbd7c89c-8h6wp   1/1     Running   0          4s
<app name>-59cbd7c89c-xpshz   1/1     Running   0          5s

You can also check that the Application resource was successfully created

$ kubectl describe app <my app>
...
Events:
  Type    Reason       Age        From        Message

Rolling back your deployment

If your newly deployed application does not work, and you wish to quickly rollback to a previous version, you can do this manually by executing the following command:

kubectl rollout undo deployment.v1.apps/<your application>

Note that if your Deployment is overridden by the Application resource, so if this is resynced / redeployed, the version and settings specified there will be effectuated.

A more detailed description on how this works can be found here

Resync your application

If you want to let naiserator recreate all the resources spawned by your Application, you can do so without deleting and redeploying it.

You can either run kubectl edit application <your app> and delete the .status.synchronizationHash field or run the following command:

kubectl patch application <your app> -p '[{"op": "remove", "path": "/status/synchronizationHash"}]' --type=json

Verify that your application has been resynced:

$ kubectl describe app <your app>
...
