Create and Manage Resources in GCP (Greenfield Workflow)

Step 1:

Choose the excel sheet template from Excel Templates. Fill the Excel with appropriate values and copy at /cd3user/gcp/<prefix>

Copy CD3 Excel File

While using the container launched using RM Stack, local path /cd3user/mount_path on the VM is mapped to /cd3user/ inside the container. So the Excel template can be copied at /cd3user/mount_path/gcp/<prefix>/ on the VM. Below is the sample command to copy the Excel template from local system to container:
```
scp -i <private key pushed to VM while creating stack> <path to excel file on local> cd3user@<Public/Private IP of the VM>:/cd3user/mount_path/gcp/<prefix>
```
Note that the user cd3user can be used to connect to the VM because same key is pushed for opc as well as cd3user.

Step 2:

Modify /cd3user/gcp/<prefix>/<prefix>_setUpGCP.properties.
Update parameters: cd3file parameter to the location of CD3 excel file and workflow_type to create_resources as shown below.
The other parameters are already updated with correct values.

[Default]

#Input variables required to run setUpGCP script

#path to output directory where terraform files will be generated. eg. /cd3user/gcp/<prefix>/terraform_files
outdir=

#prefix for output terraform files eg demo
prefix=

# Auth Params
# auth mechanism for OCI APIs - api_key,instance_principal,session_token
auth_mechanism=api_key

#input credentials file for service account eg /cd3user/gcp/<prefix>/gcp_api_private.pem
config_file=

#path to cd3 excel eg /cd3user/gcp/<prefix>/CD3-Customer.xlsx
cd3file=

#specify create_resources to create new resources in GCP(greenfield workflow)
#specify export_resources to export resources from GCP(non-greenfield workflow)
workflow_type=create_resources

Step 3:

Execute the setUpCloud.py script to start creating the terraform configuration files.

Command to Execute:

cd /cd3user/oci_tools/cd3_automation_toolkit/

python setUpCloud.py gcp /cd3user/gcp/<prefix>/<prefix>_setUpGCP.properties

Example Execution

See below image for DB@GCP options. Could select either of the options or choose to create ADB and Exa together.

CD3 Toolkit Process

Choose the resources by specifying a single option (for choosing one of these resources) or comma-separated values (to choose multiple resources) as shown in the sample screenshot above.

Expected Outputs:

The tfvars files for the selected services will be generated at the following path: /cd3user/gcp/<prefix>/terraform_files/

Step 4:

Change the directory to /cd3user/gcp/<prefix>/terraform_files/

Execute:

terraform init - To initialize and prepare the working/out directory so Terraform can run the configuration

terraform plan - To preview any changes before applying them

terraform apply - To make the changes defined by Terraform configuration to create, update, or destroy resources in GCP
