+## Couchbase Cluster on Azure Container Instances (ACI) 
+___
+#### What are Azure Container Instances
+ACI containers are conceptually similar to pods in Kubernetes.  While not truly orchestration, ACI
+allows grouping around first-class container objects. The containers within the group can communicate with each other on a private network by default. 
+External communication is established via a randomly assigned public IP.<br>
+It is important to be aware that ACI is in preview and is not for production use.  
+#### Why use ACI
+ACI allows you to easily run containers on Azure with a single command. There is no managing of Virtual 
+Machines and other infrastructure components.  [Billing](https://azure.microsoft.com/en-us/pricing/details/container-instances/) 
+is at a granularity of the duraction of cores, memory and requests.  This is more flexible and accurate than the standard
+set VM size approach.
 
-Describes how to use Azure Container Instances with Couchbase
+#### Prerequisites:
+
+* A Microsoft Azure account. Create an [account](https://azure.microsoft.com/en-us/free/) if required.
+
+The [Azure Cloud Shell](https://docs.microsoft.com/en-us/azure/cloud-shell/limitations) is command-line for this example so that the Azure Portal can be used exclusively.
+

+
+#### Create a resource group
+```
+s@Azure:~$ az group create -l eastus -n couchbaseonaciRG
+```
+After successful creating the resource group the console prints the output:
+```
+{
+  "id": "/subscriptions/XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXXX/resourceGroups/couchbaseonaciRG",
+  "location": "eastus",
+  "managedBy": null,
+  "name": "couchbaseonaciRG",
+  "properties": {
+    "provisioningState": "Succeeded"
+  },
+  "tags": null
+}
+```
+
+#### Create an ACI using the cloud shell:
+![create aci image](https://github.com/sliburd/azure-container-instances-couchbase/blob/master/screenshots/created_ACI_using_command_line_creating_status.PNG)
+
+The provisioningState specifies "*Creating*".<br>
+Wait about a minute then execute the container show command to make sure the instance has been provisioned successfully:
+
+```
+s@Azure:~$ az container show --name acicbexample -g couchbaseonaciRG
+```
+Pay attention to the port, IP and provisioningState (should be *"Succeeded"*).
+![after creation of aci](https://github.com/sliburd/azure-container-instances-couchbase/blob/master/screenshots/aci_created__port_ip_status.PNG)
+
+We can begin starting the cluster by opening **http://\<IP\>:8091** in a web browser.
+
+![setup](https://github.com/sliburd/azure-container-instances-couchbase/blob/master/screenshots/Couchbase_Setup_page.PNG)
+
+#### Start the cluster via the Web Console:
+1. Select "*Start a new cluster*".
+2. Set the "*Data RAM Quota*" and "*Index RAM Quota*" to 512 MB.
+3. Leave the other fields as the defaults and hit "*Next*".
+4. Choose the choose the "beer-sample" bucket and continue to hit "*Next*".
+5. Continue to hit "*Next*" following the instructions.
+6. On the final step enter a username and password for the administrator account.

+![final configure](https://github.com/sliburd/azure-container-instances-couchbase/blob/master/screenshots/Final_configure_step.PNG)
+
+The cluster is running, you will notice that you have one active server. 
+#### Run a query
+We will use data from the beer-sample bucket chosen during setup for a N1QL query:
+1. Navigate to the "*Query*" tab.
+2. Type "select `beer-sample`.* from `beer-sample`;" (without the quotes) in the query text box and hit "*Execute*". 
+3. Observe the results and explore the different output format tabs.
+![query results](https://github.com/sliburd/azure-container-instances-couchbase/blob/master/screenshots/Beer_sample_n1ql_query.PNG)
+
+  #### Clean up
+  Tear-down is simply deleting the container using the command:
+
+  ```s@Azure:~$ az container delete --name acicbexample --resource-group couchbaseonaciRG --yes```
+
+  Now we can do a check that the container is gone by the command:
+  ![container show after delete](https://github.com/sliburd/azure-container-instances-couchbase/blob/master/screenshots/container_show_after_delete.PNG)
+  The command returned nothing, which indicates the container no longer exists.
+
+  That is it!  We are finished.  Using ACI is that simple and easy.
