# Redis Cluster Aof - Terraform
2+
3+
## Setup
4+
5+
<walkthrough-author name="[email protected]" analyticsId="UA-125550242-1" tutorialName="redis_cluster_aof" repositoryUrl="https://github.com/terraform-google-modules/docs-examples"></walkthrough-author>
6+
7+
Welcome to Terraform in Google Cloud Shell! We need you to let us know what project you'd like to use with Terraform.
8+
9+
<walkthrough-project-billing-setup></walkthrough-project-billing-setup>
10+
11+
Terraform provisions real GCP resources, so anything you create in this session will be billed against this project.
12+
13+
## Terraforming!
14+
15+
Let's use {{project-id}} with Terraform! Click the Cloud Shell icon below to copy the command
16+
to your shell, and then run it from the shell by pressing Enter/Return. Terraform will pick up
17+
the project name from the environment variable.
18+
19+
```bash
20+
export GOOGLE_CLOUD_PROJECT={{project-id}}
21+
```
22+
23+
After that, let's get Terraform started. Run the following to pull in the providers.
24+
25+
```bash
26+
terraform init
27+
```
28+
29+
With the providers downloaded and a project set, you're ready to use Terraform. Go ahead!
30+
31+
```bash
32+
terraform apply
33+
```
34+
35+
Terraform will show you what it plans to do, and prompt you to accept. Type "yes" to accept the plan.
36+
37+
```bash
38+
yes
39+
```
40+
41+
42+
## Post-Apply
43+
44+
### Editing your config
45+
46+
Now you've provisioned your resources in GCP! If you run a "plan", you should see no changes needed.
47+
48+
```bash
49+
terraform plan
50+
```
51+
52+
So let's make a change! Try editing a number, or appending a value to the name in the editor. Then,
53+
run a 'plan' again.
54+
55+
```bash
56+
terraform plan
57+
```
58+
59+
Afterwards you can run an apply, which implicitly does a plan and shows you the intended changes
60+
at the 'yes' prompt.
61+
62+
```bash
63+
terraform apply
64+
```
65+
66+
```bash
67+
yes
68+
```
69+
70+
## Cleanup
71+
72+
Run the following to remove the resources Terraform provisioned:
73+
74+
```bash
75+
terraform destroy
76+
```
77+
```bash
78+
yes
79+
```
