+### Exposing container network (for MacOS)
+
+Docker for macOS does not expose container networks directly on the MacOS host, for this we will use
+[docker-mac-net-connect](https://github.com/chipmk/docker-mac-net-connect), which lets you connect directly
+to Docker-for-Mac containers via IP address. You can install and start it with following command:
+
+```bash
+# Install via Homebrew
+$ brew install chipmk/tap/docker-mac-net-connect
+
+# Run the service and register it to launch at boot
+$ sudo brew services start chipmk/tap/docker-mac-net-connect
+```
+
+### Docker Images
+
+You can skip this section if you have an x86_64 machine. If you're using Mac M1, then the x86_64 docker images
+will not work out of the box. You would need to use images that are built with support for arm as well.
+
+We're building all the docker images for both platforms except external images. The only external image relevant
+here is keycloak. You'd need to update the keycloak image for the deployment, which can be done by adding the
+override for the keycloak deployment to update the image:
+
+```yaml
+security:
+ keycloak:
+ initial_root_password: <SANITIZED>
+ overrides:
+ image:
+ repository: quay.io/nebari/keycloak
+ tag: sha-b4a2d1e
+```
