Before you begin

Verify that the IIoT Core Services 5.0.0 image that you want to update is installed on the cluster (installation node).
Back up the existing IIoT Core Services 5.0.0 configuration file before running the updater. In <lei_installation_directory>/lei-installer-release-5.0.0/, run the following command:
```
kubectl get secret -n hiota hiota-installation-configuration-values-secret -o=jsonpath="{.data.configuration\.yaml}" | base64 --decode > configuration.yaml
```

Perform the following steps to upgrade IIoT Core Services:

Procedure

Log in as a root user on the installation node.
Go to https://support.pentaho.com, log in, and download the patch file iiot-core-5.0.1-patch.tgz.
Verify that the iiot-core-5.0.1-patch.tgz is located in the iiot-installer-release-5.0.0 directory.

Open the patch file using the following commands:

tar -xvf iiot-core-5.0.1-patch.tgz
cd iiot-installer-release-5.0.0

Run the following commands to install the requirements:

export PATH=$PATH:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
ln -sf /usr/bin/python3 /usr/bin/python
pip3 install -r requirements.txt

If you are installing on GKE, run the following commands to tag the Docker images and push them to the hosted Docker Trusted Registry (DTR).
```
cd <installation folder>
./tag-push-docker-images.sh
```
Run the update script:
```
./lei_update.sh
```
In the IIoT Core Services UI, verify that assets, routes, and devices have migrated correctly.

Results

Your IIoT Core Services 5.0.0 installation is now updated to v5.0.1.
