Uninstall the resource specification injection (RSI) webhook if you plan to uninstall IBM Cloud Pak® for Data or if you no longer plan to use the RSI feature to create patches.

Who needs to complete this task?

A cluster administrator must complete this task.

When do you need to complete this task?

Complete this task if one of the following statements is true:

You plan to uninstall all instances of IBM Cloud Pak for Data from the cluster
You no longer plan to use the RSI feature to create patches

Before you begin

Complete the following steps in each project (namespace) where the RSI feature is enabled:

Get a list of all patches in the project:

cpd-cli manage get-rsi-patch-info \
--cpd_instance_ns=${PROJECT_CPD_INSTANCE} \
--all

For details, see get-rsi-patch-info.

Set active patches to inactive.
Before you run the command, replace <patch-name> with the name of the patch that you want to make inactive.
```
cpd-cli manage create-rsi-patch \
--cpd_instance_ns=${PROJECT_CPD_INSTANCE} \
--patch_name=<patch-name> \
--state=inactive
```
For details, see create-rsi-patch.

Delete the patches in the project.

cpd-cli manage delete-rsi-patch \
--cpd_instance_ns=${PROJECT_CPD_INSTANCE} \
--all

For details, see delete-rsi-patch.

Disable the RSI feature in the project:
IBM Cloud Pak foundational services is installed in ibm-common-services
```
cpd-cli manage disable-rsi \
--cpd_instance_ns=${PROJECT_CPD_INSTANCE}
```
IBM Cloud Pak foundational services is installed in project other than ibm-common-services
```
cpd-cli manage disable-rsi \
--cpd_instance_ns=${PROJECT_CPD_INSTANCE} \
--cs_ns=${PROJECT_CPFS_OPS}
```

Procedure

Run the cpd-cli manage login-to-ocp command to log in to the cluster as a user with sufficient permissions to complete this task. For example:
```
cpd-cli manage login-to-ocp \
--username=${OCP_USERNAME} \
--password=${OCP_PASSWORD} \
--server=${OCP_URL}
```
Tip: The login-to-ocp command takes the same input as the oc login command. Run oc login --help for details.

Uninstall the webhook:

The cluster pulls images from the IBM Entitled Registry

cpd-cli manage uninstall-rsi \
--cs_ns=${PROJECT_CPFS_OPS}

The cluster pulls images from a private container registry

cpd-cli manage uninstall-rsi \
--cs_ns=${PROJECT_CPFS_OPS} \
--rsi_image=${PRIVATE_REGISTRY_LOCATION}/cpd/zen-rsi-adm-controller:4.6.5-x86_64
