Terraform deployment

Download the terraform stack

Our terraform stack is available at https://gitlab.com/ohlala-automation-solutions-public/beta/terraform-stack or you can directly download the zip file.

Clone the repository locally.

Instructions

Please have a look through the readme or the code of the repository. You will see what resources are deployed and what parameters are needed.

You can download terraform from their website.

Deployment

Open your favorite shell and navigate to the root folder of the repository.

Initialize the repository:

terraform init

The output should look something like this:

Initializing the backend...
Initializing provider plugins...
- Reusing previous version of hashicorp/aws from the dependency lock file
- Reusing previous version of hashicorp/random from the dependency lock file
- Using previously-installed hashicorp/aws v5.91.0
- Using previously-installed hashicorp/random v3.7.1

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

View planned changes:

terraform plan

The output should look something like this:

...
Plan: 56 to add, 0 to change, 0 to destroy.

Changes to Outputs:
  + ohlala_url = (known after apply)

Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you run "terraform apply" now.

Apply changes if the resources in the plan looks fine to you:

terraform apply

The output should look something like this:

...
Apply complete! Resources: 56 added, 0 changed, 0 destroyed.

Outputs:

ohlala_url = "http://ohlala20250328133845277200000011-xxxxxxx.eu-west-1.elb.amazonaws.com"

N.B.: there are more advanced usage of terraform that may better suit your needs.

subnets       = ["subnet-05c070af686daf105", "subnet-059ec56900f58b340"]
inbound_cidr  = "88.170.94.38/32"
instance_type = "t3.medium"
key_name      = "etienne-test"
