+# Run the PoS Application in a VM
+
+You can run all the services of the application in a single VM as a system
+service. Simply copy the [**init-vm.sh**](init-vm.sh) file into your VM and then
+execute it from inside the VM. This sets up all the services of the application
+to run as a system service inside your VM.
+
+```sh
+sudo bash init-vm.sh
+```
+
+Note that the `inventory service` and the `payments service`
+[expects the hostname `mysql-db` to resolve to an IP address](init-vm.sh#L115)
+pointing to a MySQL service. This is because these _systemd service_ files were
+written for a use-case where the PoS application VM is run inside an Anthos on
+bare metal cluster using [Anthos VMRuntime](https://cloud.google.com/anthos/clusters/docs/bare-metal/latest/how-to/vm-workloads). In that use-case we have a MySQL container being made
+available to the services via a `Kubernetes Service` named `mysql-db`. _See the
+[full guide for that here](https://github.com/GoogleCloudPlatform/anthos-samples/tree/main/anthos-vmruntime)._
+
+If you don't want the application connecting to an external MySQL instance, then
+you can simply change the `SPRING_PROFILES_ACTIVE` environment variable in the
+systemd service files to **inmemory**. This will spawn an embedded H2 database
+per service that they will use.
+
+```sh
+# line 116 (pos_inventory.service) of the init-vm.sh file
+Environment=SPRING_PROFILES_ACTIVE=inmemory
+
+# line 141 (pos_payments.service) of the init-vm.sh file
+Environment=SPRING_PROFILES_ACTIVE=inmemory
+```
+
+### Creating an image of this VM to be run in an Anthos cluster using Anthos VMRuntime
+
+> Make sure you stop the VM first.
+- Set your environment variables
+    ```sh
+    export PROJECT_ID=<YOUR_GCP_PROJECT>
+    export ZONE=<YOUR_GCP_ZONE>
+    export BUCKET_NAME=<STORAGE_BUCKET_NAME>
+    ```
+
+- Create a `Disk Image` of the VM
+    ```sh
+    gcloud compute images create pos-vm-image \
+        --source-disk=pos-vm \
+        --source-disk-zone=${YOUR_GCP_ZONE} \
+        --project=${PROJECT_ID}
+    ```
+
+- Create `Cloud Storage Bucket` to store the image
+    ```sh
+    gsutil mb -p ${PROJECT_ID} -c standard -b on gs://${BUCKET_NAME}
+    ```
+
+- Make the bucket **publicly readable**
+    ```sh
+    gsutil iam ch allUsers:objectViewer gs://${BUCKET_NAME}
+    ```
+
+- Upload the Disk Image we create to the Cloud Storage Bucket
+    ```sh
+    gcloud compute images export \
+        --destination-uri gs://${BUCKET_NAME}/pos-vm.qcow2 \
+        --image pos-vm-image \
+        --export-format qcow2 \
+        --project ${PROJECT_ID}
+    ```
+
+Now you can use the URL `https://storage.googleapis.com/${BUCKET_NAME}/pos-vm.qcow2`
+to refer to the VM image when creating your VM in an Anthos VMRuntime enabled
+cluster.

 # Kubernetes manifests

+```sh
+# generate the release kubernetes manifests
+skaffold render -p release > pos-quickstart.yaml

+# apply the yaml files to the cluster
+kubectl apply -f pos-quickstart.yaml
+```

+#### 🤷 &nbsp; I don't have [skaffold](https://skaffold.dev/docs/install/) installed !

 This directory holds the Kubernetes manifest files that can be used to deploy
 the **Point-of-Sale** application. The manifests are seperated into categories
 based on the deployment environment. You will notice multiple directories _(
