# Elastic Cloud Enterprise setup script for Microsoft Azure



This is a set of automation tools and scripts that will automate the creation of the Azure environment for Elastic Cloud Enterprise (ECE).



## Terraform-based deployment



This method uses Packer to generate a base image with all the pre-requisites, and a Terraform configuration to deploy the Azure resources. It requires to prepare the image up front, but makes the deployment itself much faster since the OS is already prepared.



### Preparing the environment



This method require you to first define some environment variables to authorize Packer and Terraform to access Azure.



```

export ARM_SUBSCRIPTION_ID=00000000-0000-0000-0000-000000000000

export ARM_CLIENT_ID=00000000-0000-0000-0000-000000000000

export ARM_CLIENT_SECRET=00000000-0000-0000-0000-000000000000

export ARM_TENANT_ID=00000000-0000-0000-0000-000000000000

```



### Run Packer



First create a Resource Group:



```

az group create -n ece-base-image -l westeurope

```



Make sure you use the same name and location as used in the Packer configuration.



Then run Packer:



```

packer build ece-packer.json

```



Once the VM image has been created, retrieve its ID using the following command:



```

az vm image list -g ece-base-image

```



The ID will have this form:



```

/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/ece-base-image/providers/Microsoft.Compute/images/ece-base-image

```



### Run Terraform



Copy the image ID into the `image_id` variables in `veriables.tf`. It should look like this:



```

variable "image_id" {

  default = "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/ece-base-image/providers/Microsoft.Compute/images/ece-base-image"

}

```



You can also edit other variables, like the VM size and the data disk size (in GB).



Then run Terraform:



```

terraform apply

```



The Terraform configuration will execute the `disk_setup.sh` script in order to format the data disk. The script will also change the Docker configuration to point to the newly created data directory.



## Script-based deployment



This method uses the `az` command to provision the ECE resources in Azure. It uses base Ubuntu images and prepares them according to the ECE documentation.



### Provisioning the resources



Run `provision.sh` to provision three Virtual Machines ready to be used to deploy ECE, including networking, security, and OS pre-requisites. The `node_setup.sh` and `disk_setup.sh` scripts will be executed on each VM in order to prepare the OS. Each VM will be rebooted for the system settings to take effect.



## Installing ECE



Once the machines are prepared, you can log into them to install ECE.



To find the public IP addresses allocated to the nodes, use the following command:



```

az network public-ip list -g ece --query '[].ipAddress'

```



Log into the first machine and change to the `elastic` user:



```

sudo su - elastic

```



Then install ECE on the first host using the following commands:



```

curl -O https://download.elastic.co/cloud/elastic-cloud-enterprise.sh

chmod +x ./elastic-cloud-enterprise.sh

./elastic-cloud-enterprise.sh install --host-storage-path /data/elastic

```



Then follow the ECE instructions to install on all the hosts.
