Applications Created Through App Designer

If the application in CCE 1.0 version is created through App Designer, follow the steps in this section to migrate the application to CCE 2.0. In CCE 2.0, use the custom Helm chart to create applications. For more information, see Chart Management.

Procedure

Log in to the console of CCE 1.0. In the navigation pane, click App Manager. Then, click the name of the application to be migrated to go to the details page. Obtain Component Name and Service Name.
Connect to a cluster. For details, see Connecting to a Cluster Through kubectl.
Run the following commands on the kubectl client to obtain the YAML files related to the application.
kubectl get rc new-appcomponent-1-11d3 -o yaml > new-appcomponent-1-11d3.yaml

kubectl get svc new-port-3 -o yaml > new-port-3.yaml

In the preceding commands, replace new-appcomponent-1-11d3 and new-port-3 with the values obtained in 1.

Edit the new-appcomponent-1-11d3.yaml file by deleting the lines in bold and modifying the lines in Italic.

Connect the kubectl client to the CCE cluster of the latest version. For details, see Connecting to a Cluster Through kubectl.
Run the following commands to create the application again:
kubectl create -f new-appcomponent-1-11d3.yaml

kubectl create -f new-port-3.yaml
