Infrastructure as Code (IaC)

If you get stuck, delete the terraform.tfstate file, and manually destroy the resources that were created.

Get token and SSH key name from your DigitalOcean account

export OCEAN_TOKEN="0f97..."
export OCEAN_SSH_KEY="greg..."

Enable logging to STDOUT

Other log levels include: TRACE, DEBUG, INFO, WARN, ERROR

export TF_LOG=ERROR

Initialize local directory

cd ~/projects/infrastructure/
terraform init

Plan then apply

terraform plan  -var "do_token=${OCEAN_TOKEN}" -var "pvt_key=$HOME/.ssh/id_rsa" -var "ocean_ssh_key=${OCEAN_SSH_KEY}"
terraform apply -var "do_token=${OCEAN_TOKEN}" -var "pvt_key=$HOME/.ssh/id_rsa" -var "ocean_ssh_key=${OCEAN_SSH_KEY}" --auto-approve

Check the state after server created

terraform show terraform.tfstate

Destroy server; check terraform.tfplan before applying

terraform plan -destroy -out=terraform.tfplan -var "do_token=${OCEAN_TOKEN}" -var "pvt_key=$HOME/.ssh/id_rsa" -var "ocean_ssh_key=${OCEAN_SSH_KEY}"
terraform apply terraform.tfplan
