This topic explains how to delete environments in Apigee hybrid. For an introduction, see About environments.
About deleting environments
To delete an environment properly, you must make several configuration changes and
apply them to your cluster. These changes include removing the environment definition and
references to it from
your overrides file, deleting the
udca components, and finally re-applying your overrides to
restore your cluster without
including the environment you wish to delete.
The reason you can't only delete the environment in one step is because the other elements,
udca are connected to each environment through their internal configurations. Only by
deleting them and re-applying them can you properly delete an environment.
How to delete an environment
Assume that you have two environments, test and prod. In your overrides file, the definitions might look something like this:
... envs: - name: test serviceAccountPaths: synchronizer: "your_keypath/synchronizer-manager-service-account.json udca: "your_keypath/analytic-agent-service-account.json - name: prod serviceAccountPaths: synchronizer: "your_keypath/synchronizer-manager-service-account.json udca: "your_keypath/analytic-agent-service-account.json ...
To delete the prod environment, follow these steps:
- Copy your original overrides file -- the one that contains both the prod
and test environment definitions --
to a new file called, for example,
- Delete the
testenvironment definition from
virtualhosts, leaving only the prod definitions. For example:
... envs: - name: prod serviceAccountPaths: synchronizer: "your_keypath/synchronizer-manager-service-account.json udca: "your_keypath/analytic-agent-service-account.json ...
- Remove everything else from
cassandraconfig, if present:
After making the above changes, your overrides file should look something like this:
... envs: - name: prod serviceAccountPaths: synchronizer: "your_keypath/synchronizer-manager-service-account.json" udca: "your_keypath/analytic-agent-service-account.json" cassandra: replicaCount: 3 resources: requests: cpu: 3500m memory: 7Gi storage: storageClass: pd-ssd capacity: 10Gi
- Run this command to delete the specified components:
apigeectl delete -f prod-delete.yaml --env=prod --datastore
- Open your original overrides file (the one that includes both the test and prod environment definitions).
- Delete the
prodenvironment definition from the
envselement. You only want the
testenvironment definition to be present in the file.
- Apply the modified overrides file to your cluster. This command will recreate the deleted
elements and, because it is omitted, not recreate the
apigeectl apply -f original-overrides.yaml --env=test
Save your changes.
- Open a browser and navigate to the hybrid UI at Apigee UI.
- Remove the environment using the steps described Delete an existing environment in the Hybrid UI.
You're not quite done. You must now update the environments in the hybrid UI.
