**NOTE** 'defaultImages' container images names in the config file will need to be updated with **your container registry URI**. Here's an example command in Linux to do this (just replace YOUR_REGISTRY_URI with the appropriate location in your environment, should be run from the config directory):
```
-sed -i 's|gcr.io/matchmaker-dev-201405|YOUR_REGISTRY_URI|g' matchamker_config.json
+sed -i 's|gcr.io/matchmaker-dev-201405|YOUR_REGISTRY_URI|g' matchmaker_config.json
```
For MacOS the `-i` flag creates backup files when changing the original file in place. You can use the following command, and then delete the `*.backup` files afterwards if you don't need them anymore:
```
-sed -i'.backup' -e 's|gcr.io/matchmaker-dev-201405|YOUR_REGISTRY_URI|g' matchamker_config.json
+sed -i'.backup' -e 's|gcr.io/matchmaker-dev-201405|YOUR_REGISTRY_URI|g' matchmaker_config.json
```
If you are using the gcr.io registry on GCP, the default URI is `gcr.io/<PROJECT_NAME>`.
