## Create Blob Storage location for Terraform State file
8
-
1. Edit the [variables](https://github.com/thomast1906/DevOps-Journey-Using-Azure-DevOps/blob/main/1-Initial-Setup/scripts/create-terraform-storage.sh#L3-L4)
9
-
2. Run the script `./scripts/create-terraform-storage.sh`
10
-
3. The script will create the following:
11
-
- Azure Resource Group
12
-
- Azure Storage Account
13
-
- Azure Blob storage location within Azure Storage Account
8
+
### Prerequisites
9
+
-[ ] Azure CLI installed and configured
10
+
-[ ] Basic understanding of Azure Storage concepts
11
+
12
+
### Steps
13
+
14
+
1.**Customise Variables**
15
+
- Open the [create-terraform-storage.sh](https://github.com/thomast1906/DevOps-Journey-Using-Azure-DevOps/blob/main/1-Initial-Setup/scripts/create-terraform-storage.sh) script.
16
+
- Locate the following lines:
17
+
18
+
```bash
19
+
RESOURCE_GROUP_NAME="devops-journey-rg-oct2024"
20
+
STORAGE_ACCOUNT_NAME="devopsjourneyoct2024"
21
+
```
22
+
23
+
- Replace the placeholders with your desired names.
24
+
25
+
2. **Run the Script**
26
+
27
+
- Run the following commandin your terminal:
28
+
29
+
```bash
30
+
./scripts/create-terraform-storage.sh
31
+
```
32
+
33
+
3. **What's Happening Behind the Scenes?**
34
+
The script performs these actions:
35
+
- [ ] Creates an Azure Resource Group
36
+
- [ ] Sets up an Azure Storage Account
37
+
- [ ] Establishes an Azure Blob storage container
38
+
39
+
### 🔍 Verification
40
+
To ensure everything was set up correctly:
41
+
42
+
1. Log into the [Azure Portal](https://portal.azure.com).
43
+
2. Navigate to your newly created Resource Group.
44
+
3. Verify the presence of the Storage Account.
45
+
4. Within the Storage Account, check for the Blob container.
46
+
5. It should look similar to this:

17
-
This setup ensures that your Terraform state file is securely stored and easily accessible for your deployments.
50
+
### 🧠 Knowledge Check
51
+
After running the script, try to answer these questions:
52
+
1. Why is it important to use remote state storage for Terraform?
53
+
2. What are the benefits of using Azure Blob Storage for this purpose?
54
+
3. How would you access this state file in your Terraform configurations?
55
+
56
+
#### 💡 Pro Tip Consider: setting up access policies and encryption for your storage account to enhance security. Azure provides several options for this, including Azure AD authentication and Azure Key Vault integration.
