Terraform automation experiments

Terraform experiments in creating VM's in AWS, Azure and Oracle OCI for registration in Portainer

Create SSH Encryption Keys

ssh-keygen -t rsa -N "" -b 2048 -C portainer-ssh-key -f portainer-ssh-key
chmod 400 portainer-ssh-key
chmod 644 portainer-ssh-key.pub

Remove ip known_hosts (tips)

ssh-keygen -R "[IP Address]"

Terraform commands

Create VM commands

terraform init -reconfigure
#terraform init -upgrade 
terraform validate
terraform plan -out main.tfplan
terraform apply main.tfplan

Destroy VM commands

terraform plan -destroy -out main.destroy.tfplan
terraform apply main.destroy.tfplan

Show Terraform outputs

terraform output

Activate Terraform logs

export TF_LOG="DEBUG"
export TF_LOG_PATH="tmp/terraform.log"

Connect remote compute host

ssh -i portainer-ssh-key ubuntu@IP
