Terraform plan to deploy centos7 droplet(s) at Digital Ocean

Requirements

• Terraform
• Account at Digital Ocean
• Generated token at Digital Ocean
• Ssh key added to your Digital Ocean account
• Get your pub key fingerprint, use ssh-keygen -E md5 -lf when md5.
• Enough credits on your Digital Ocean account :-)

Features

• Deployment centos7 OS with terraform
• System update to latest centos7

Instructions

Set environment variables

export DO_PAT=[your generated toke]
export SSH_FINGERPRINT="[your public key fingerprint]"
export TF_LOG=1

Check your infrastructure execution plan

terraform plan \ 
-var "do_token=${DO_PAT}" \ 
-var "pub_key=~/.ssh/id_rsa.pub" \
-var "pvt_key=~/.ssh/id_rsa" \
-var "ssh_fingerprint=$SSH_FINGERPRINT"

Apply your infrastructure execution plan

terraform apply \ 
-var "do_token=${DO_PAT}" \ 
-var "pub_key=~/.ssh/id_rsa.pub" \
-var "pvt_key=~/.ssh/id_rsa" \
-var "ssh_fingerprint=$SSH_FINGERPRINT"

Show your infrastructure setup
