Modifying Edge
For this example, assume that the Edge is deployed using the c8yedge-sample.yaml.
Example configuration change
Change the spec.domain
field to sample.myown.iot.com
and if required update the spec.licenseKey
accordingly.
Save the file and use the command below to apply the changes:
kubectl apply -f c8yedge-sample.yaml
To verify the Edge deployment, see Verifying the Edge installation.
Upgrading Edge
The Edge operator follows the recreate update strategy to upgrade the Edge deployment.
Recreating update strategy is an all-or-nothing process that updates all aspects of the system at once with a brief downtime period. The Edge operator selects all the outdated pods and deactivates them at once. Once all old pods are deactivated, the Edge operator creates updated pods for the entire system. Edge is not operational while the old pods are deactivating and until the final updated pod is created.
For this example, assume that Edge is deployed using the c8yedge-sample.yaml.
Starting the upgrade
To upgrade the Edge deployment, change the spec.version
field in the Edge CR file to the appropriate version. For example to 1018.0.1
.
Save the file and use the command below to apply the changes:
kubectl apply -f c8yedge-sample.yaml
To verify the Edge deployment, see Verifying the Edge installation.

Upgrading the Edge operator

Uninstalling Edge
You can uninstall Edge either by:
-
Deleting the Edge Custom Resource using the command:
kubectl delete edge c8yedge -n c8yedge
-
Through the c8yedge-sample.yaml that you used to install Edge.
For example, you can uninstall by using the command:
kubectl delete -f c8yedge-sample.yaml
InfoSubstitute the namespace name c8yedge in the command above with the specific namespace name you have specified in your Edge CR.
