Upgrading Docker Event Gateways

To upgrade a Docker Event Gateway, restart the Docker gateway with the new Event Gateway image.

Procedure

Edit the backup of the Docker run command that you generated when you installed the gateway, and update the following properties:
1. The image reference. Set the image reference to your target version. For example:
```
-d icr.io/cpopen/ibm-eventendpointmanagement/egw:11.8.0
```
2. If the new version requires an updated license ID, then update LICENCE_ID.
3. If you made additional configuration changes to your Docker gateway since installation, then ensure that your Docker command includes those changes.
Uninstall the previous Docker gateway.
1. Run the following command to list the running containers:
```
docker ps
```
2. Locate the gateway in the list and stop the gateway container:
```
docker stop <container_id>
```
3. After the container is stopped, delete the gateway container and image:
```
docker rm <gateway_container>
```
```
docker rmi <gateway_image_name>
```
Run the Docker command that you prepared in step 1.
