# Deploying a Service Fabric cluster based on Linux nodes

## A. Unsecured cluster (SF Linux cluster)
For a secured cluster, see option B. below.

You can always deploy a SF cluster through the Azure portal, as explained in this article: https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-get-started-azure-cluster

However, when creating a cluster, there are quite a few configurations to take into account, like enabling the internal DNS service or Reverse Proxy service, choosing between Linux/Windows, open/publish your application ports in the load-balancer and most of all (the most complex setup) how to create a secure cluster.

Because of those reasons, we have created a set of ARM templates and scripts so you can create, re-create and configure the SF clusters much faster, as explained below: 

Within eShopOnContainers root folder, at the folder [..\deploy\az\servicefabric\LinuxContainers](https://github.com/dotnet-architecture/eShopOnContainers/tree/dev/deploy/az/servicefabric/LinuxContainers), you can find the ARM template `servicefabricdeploy.json` and its parameters file (`servicefabricdeploy.parameters.json`) to create a Service Fabric cluster environment for Linux Containers.

## Edit the servicefabricdeploy.parameters.json file

Edit the following params in `servicefabricdeploy.parameters.json` file to set your values:

- clusterName: Name of your SF cluster
- clusterLocation: Datacenter location, like westus or westeurope
- computeLocation: Datacenter location, like westus or westeurope
- adminUserName: user-name for VMs administration
- adminPassword: user-password for VMs administration
- dnsName: Name assigned to your SF dns

Optionally, you could modify which ports are opened in the LoadBalancer for the multiple eShopOnContainer apps and API services.
By default, they are setup as:
- webMvcHttpPort:       5100
- webSpaHttpPort:       5104
- webStatusHttpPort:    5107
- IdSrvHttpRule:        5105
- BasketApiHttpRule:    5103
- CatalogApiHttpRule:   5101
- OrderingApiHttpRule:  5102
- MarketingApiHttpRule: 5110
- LocationsApiHttpRule: 5109

## Deploy the Service Fabric cluster using the script and ARM templates

Once parameter file is edited you can deploy it using [create-resources script](../readme.md).

For example, to deploy the cluster to a new resourcegroup located in westus, go to `deploy\az` folder and type:

```
create-resources.cmd servicefabric\LinuxContainers\servicefabricdeploy qa-eshop-sflinux-resgrp -c westus
```

You should see a similar execution to the following:
![image](https://user-images.githubusercontent.com/1712635/31638180-15da9f84-b287-11e7-9d4e-604f33690198.png)

Now, if you go to your subscription in Azure, you should be able to see the SF cluster already created and available, like in the following image:

![image](https://user-images.githubusercontent.com/1712635/31638398-3fc08ad8-b288-11e7-879b-fc4df0daad2b.png)

In this case, this is an unsecured SF cluster with a single Linux node, good for initial tests and getting started with SF.

## B. Secured cluster (SF Linux cluster)

Within eShopOnContainers root folder, at the folder [..\deploy\az\servicefabric\LinuxContainers](https://github.com/dotnet-architecture/eShopOnContainers/tree/dev/deploy/az/servicefabric/LinuxContainers), you can find the ARM template `servicefabricdeploysecured.json` and its parameter file (`servicefabricdeploysecured.parameters.json`) to create a secured Service Fabric cluster environment for Linux Containers (IN THIS CASE, IT IS A SECURED CLUSTER USING A CERTIFICATE).

The ARM template `servicefabricdeploysecured.json` and its parameter file (`servicefabricdeploysecured.parameters.json`) are used to create a service fabric cluster environment for linux containers secured with a certificate.

## Create Azure Keyvault service
Go to PortalAzure and create a Keyvault service. Make sure Enable access for deployment checkboxes are selected.

![image](https://user-images.githubusercontent.com/1712635/31638848-9b266530-b28a-11e7-953b-1e3ec1a54f77.png)

## Generate a certificate in Azure Keyvault
In a POWER-SHELL window, move to the folder [..\deploy\az\servicefabric\LinuxContainers](https://github.com/dotnet-architecture/eShopOnContainers/tree/dev/deploy/az/servicefabric/LinuxContainers).

**Select your Azure subscription** You might have [several Azure subscriptions](https://docs.microsoft.com/en-us/cli/azure/account#set) as shown if you type the following.

    >```
    >az account list
    >```
    If you have multiple subscription accounts, you first need to select the Azure subscription account you want to target. Type the following:
    >```
    >az account set --subscription "Your Azure Subscription Name or ID"
    >```

Execute the gen-keyvaultcert.ps1 script to generate and download a certificate from Keyvault.

```
.\gen-keyvaultcert.ps1 -vaultName <your_keyvault_service> -certName <your_cert_name> -certPwd <your_cert_pwd> -subjectName CN=<your_sf_dns_name>.westeurope.cloudapp.azure.com -saveDir C:\Users\<user>\Downloads

```

You should see a similar execution to the following:
![image](https://user-images.githubusercontent.com/1712635/31640172-93efcca0-b291-11e7-970e-5b5e6bf07042.png)

IMPORTANT: At this point, copy/cut the .PFX certificate file saved in the downloads forlder and save it in a secure place.

## Install the certificate
Install the certificate (by double-clicking on the .PFX file) under 'Current User' store location (by default location) and check it as exportable.

<img src="https://github.com/dotnet-architecture/eShopOnContainers/blob/dev/img/sf/install-cert.PNG">

Also, install the same certificate as CA (Certificate Authority) under Current User, too.

## Editing servicefabricdeploysecured.parameters.json file

Edit the parameters in `servicefabricdeploysecured.parameters.json` in a similar way you can do with the unsecured .json file shown above (clusterName, dnsName, etc.), plus edit the following values:

- sourceVaultValue: Your Azure Keyvault's RESOURCE ID (check Azure keyvault properties, similar to: /subscriptions/e1234ac1-c09c-3jaf-6767-98b3c5f1f246/resourceGroups/eshop-global-resgrp/providers/Microsoft.KeyVault/vaults/eshopkeyvault")

- certificateUrlValue: Your certificate Secret Identifier (check Azure Keyvault secret certificate properties, should be in the format of https://<name of the vault>.vault.azure.net:443/secrets/<exact location>, similar to: 
https://eshopkeyvault.vault.azure.net/secrets/pro-eshop-sflinux-cluster-cert/fd47684442c04cdj83b3hfe4h8e08123)

- certificateThumbprint: certificate thumbprint (check azure Keyvault certificate thumbprint, something like 69JK453486D55A6818577Z0699100365HDK70FCE)

## Deploy the secured SF Linux cluster

Once parameters file is edited you can deploy it using [create-resources script](../readme.md).
Use a command prompt window positioned into the deploy\az folder.

```
create-resources.cmd servicefabric\LinuxContainers\servicefabricdeploysecured pro-eshop-sflinux-resgrp -c westus
```
The execution should be something like the following:
![image](https://user-images.githubusercontent.com/1712635/31642529-54479704-b2a0-11e7-90ee-2abf32c92205.png)

Once the cluster is created you can explore it with Azure's portal, like in the following image:

## Deploy eShopOnServiceFabric with Visual Studio.

Modify the cloud.xml file of each Service Fabric application in PublishProfile directory and set  your certificate settings to be able to deploy eshopOnContainers in the secured cluster:
