This enables the user to better understand and troubleshoot a Terraform project. As source for this it uses the Terraform graph information which can be printed via the command “terraform graph”. The website Webgraphviz visualises the Terraform code. Ssh -i private-key-private-host.pem -p 7777 #Connect to the local port which is connected to the private host Ssh -L 7777::22 a second terminal locally #Open a local port which forwards the traffic to the private host Accessing the private host via local port forwarding #Get keys if not already done To enhance security, it is also possible to tighten the security group so that only one IP (the Bastion host) could access the private host on port 22 (SSH). With SSH port forwarding, it is possible to access the private host without storing the private key on the Bastion host. Anyone who possesses the private key within the VPC could therefore access the private host. The disadvantage of the above solution is that the Bastion host requires the private key of the private host to be stored remotely. ssh -i private-key-private-host.pem Option, more secure with local port forwarding ssh -i private-key-bastion-host.pem 400 private-key-private-host.pemĬonnect via SSH from Bastion host to private host. #Change permission on the private key fileĬopy private key (private-key-private-host.pem) of private host to Bastion host.Ĭopy key via Cyberduck and SFTP (see below).Ĭonnect via SSH to Bastion host. Terraform output private-key-private-host > private-key-private-host.pem Terraform output private-key-bastion-host > private-key-bastion-host.pem Option to connect to Bastion host #Get the two private keys and store it in a file The IP addresses printed after Terraform has successfully built all the infrastructure is needed for the next steps.
