### Step-by-Step Azure Air Gapped Installation

This process closely mirrors the standard azure documentation with a few subtle amendments.

On your internet connected staging machine (With Docker Installed):

Build the docker image needed for deployment:

```BASH
cd src/scripts
./setup_ezdeploy.sh -d export
```

This will take some time by building the docker image, and then saving it to the scripts working directory and compressing it to "mlz.zip"

Move this file along with the repo to the destination for airgapped deployment Then execute the following

```BASH
cd src/scripts
./setup_ezdeploy.sh -d load -s <subscription id> -e "<AZURE_ENVIRONMENT>" -l "<AZURE_LOCATION>"
```

### Step-by-Step Local Installation

Running the user interface on your local workstation is not our recommended approach because it requires more setup, but it works.
