QuickStart on ASP.Net with simple Terraform scripts and ORM Stack
2+
3+
QuickStart ASP.Net on OCI with Terraform scripts (Includes ORM Stack)
4+
5+
## Deploy Using Oracle Resource Manager
6+
7+
1. Click [![Deploy to Oracle Cloud][magic_button]][magic_dotnet_stack]
8+
9+
If you aren't already signed in, when prompted, enter the tenancy and user credentials.
10+
11+
1. Review and accept the terms and conditions.
12+
13+
1. Select the region where you want to deploy the stack.
14+
15+
1. Follow the on-screen prompts and instructions to create the stack.
16+
17+
1. After creating the stack, click **Terraform Actions**, and select **Plan**.
18+
19+
1. Wait for the job to be completed, and review the plan.
20+
21+
To make any changes, return to the Stack Details page, click **Edit Stack**, and make the required changes. Then, run the **Plan** action again.
22+
23+
1. If no further changes are necessary, return to the Stack Details page, click **Terraform Actions**, and select **Apply**.
24+
25+
## Deploy Using the Terraform CLI
26+
27+
### Clone the Module
28+
29+
Now, you'll want a local copy of this repo. You can make that with the commands:
30+
31+
git clone https://github.com/oracle-quickstart/oci-dotnet.git
32+
cd oci-dotnet
33+
ls
34+
35+
### Set Up and Configure Terraform
36+
37+
1. Complete the prerequisites described [here](https://github.com/cloud-partners/oci-prerequisites).
38+
39+
1. Create a `terraform.tfvars` file, and specify the following variables:
40+
41+
```
42+
# Authentication
43+
tenancy_ocid = "<tenancy_ocid>"
44+
user_ocid = "<user_ocid>"
45+
fingerprint = "<finger_print>"
46+
private_key_path = "<pem_private_key_path>"
47+
48+
# Region
49+
region = "<oci_region>"
50+
51+
# Compartment
52+
compartment_ocid = "<compartment_ocid>"
53+
54+
````
55+
56+
### Create the Resources
57+
58+
Run the following commands:
59+
60+
terraform init
61+
terraform plan
62+
terraform apply
63+
64+
### Destroy the Deployment
65+
66+
When you no longer need the deployment, you can run this command to destroy the resources:
67+
68+
terraform destroy
69+
