title: GCP Google Cloud Platform - Terraform Commands
3+
description: Learn Terraform Commands on Google Cloud
4+
---
5+
6+
## Step-01: Introduction
7+
- Understand basic Terraform Commands
8+
- terraform init
9+
- terraform validate
10+
- terraform plan
11+
- terraform apply
12+
- terraform destroy
13+
14+
## Step-02: Terraform Core Commands
15+
```t
16+
# Configure GCP Credentials (ADC: Application Default Credentials)
17+
gcloud auth application-default login
18+
19+
# Initialize Terraform
20+
terraform init
21+
Observation:
22+
1) Initialized Local Backend
23+
2) Downloaded the provider plugins (initialized plugins)
24+
3) Review the folder structure ".terraform folder"
25+
26+
# Terraform Validate
27+
terraform validate
28+
Observation:
29+
1) Tt performs a basic syntax check on your Terraform configuration files to ensure they are syntactically valid and internally consistent.
30+
2) It does not make any changes to the files themselves but verifies that the configuration is correct according to Terraform's rules.
31+
32+
33+
# Terraform Plan to Verify what it is going to create / update / destroy
34+
terraform plan
35+
Observation:
36+
1) Verify the plan
37+
2) Verify the number of resources that going to get created
38+
3) Plan Output: terraform plan generates an execution plan that shows what actions Terraform will take to achieve the desired state described in your configuration files.
39+
4) It will list resources to be created, updated, or destroyed.
40+
41+
# Terraform Apply
42+
terraform apply
43+
[or]
44+
terraform apply -auto-approve
45+
Observations:
46+
1) Will create resources on Google cloud
47+
2) Will create terraform.tfstate file when you run the terraform apply command containing all the resource information.
48+
```
49+
50+
## Step-03: Verify the Resources created on Google Cloud
51+
- Go to Google Cloud -> VPC Networks -> vpc1
52+
53+
54+
## Step-04: Destroy Infrastructure
55+
```t
56+
# Destroy EC2 Instance
57+
terraform destroy
58+
59+
# Delete Terraform files
60+
rm -rf .terraform*
61+
rm -rf terraform.tfstate*
62+
```
63+
64+
## Step-05: Conclusion
65+
- Re-iterate what we have learned in this section
66+
- Learned about Important Terraform Commands
67+
- terraform init
68+
- terraform validate
69+
- terraform plan
70+
- terraform apply
71+
- terraform destroy
