Manual deployment¶
Performing deployments manually requires that you have access to the cluster and kubectl configured.
For automated deployments, use NAIS deploy.
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>
...

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:
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 to roll back your deployment is provided by Kubernetes.
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>
