GCP SSH連線到VM instance

GCP SSH連線到VM instance的方式如下。

建立VM instance

參考「GCP 建立Compute Engine VM instance」建立VM instance。例如VM的public IP為34.81.210.198。

VPC Firewall

Instance所在VPC的Firewall rule要設定Ingress允許本機IP（或任意IP 0.0.0.0/0）和TCP:22。這樣本機ssh連線到instance才不會被防火牆阻擋導致Operation timed out。

產生SSH key

參考「Mac 產生SSH金鑰 generate ssh key」產生SSH key。例如產生的SSH key名稱為john，SSH key私鑰路徑為~/.ssh/john_rsa。

加入SSH key

參考「GCP Compute Engine VM instance 新增SSH key」加入SSH key到VM instance。

SSH登入VM instance

開啟命令列，輸入ssh <username>@<vm-public-ip> -i <ssh-private-key-path>即可登入VM。例如ssh john@34.81.210.198 -i ~/.ssh/john_rsa。

~% ssh john@34.81.210.198 -i ~/.ssh/john_rsa
