Select EKSBastion and click Connect
Generate an SSH key pair and display the public key to be copied to GitHub. Leave the default file name by pressing enter when asked for a file to save the key, and enter a passphrase of your choice (twice to confirm). You will see the key starting from “ssh-rsa”
ssh-keygen -t rsa && \ cat /home/ec2-user/.ssh/id_rsa.pub
You will see your new public SSH key printed to the terminal like the following:
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDAnxipo/s/uvxguhwfTbNCM+iWoPa+gpQV7wKlOo5cZ+VUpekodpaiFV/QB3jq41qrZfdvAYqapJN1YZOeCkY90T3kNgLvpGNOuqOB95sLKlBCni568l9qYi/eDm/gTpGxiNwtI9muqzfRSPPTvKQLkTM49oTLjsGAWE4IaZ5YtmZkyUMDTMcjDvKSO6FtvzBhNwS6mEZ5A5P1IVYy1TdKXIXHHo5bUScddM5vyiAWjAgT5R0TwOXGEgX5HA9GkG957kP0TZfAxS2pc6C5GKBhaTpcAaz64zUpT03b28gNgw0lWbB5eqZBt1oqZRVASdU3xOmjzDRIBMF/IkU3kHkj ec2-user@ip-172-38-0-139Select and copy all the printed text of the key.
Create a new SSH key authorization in GitHub:
Start the SSH agent in your environment if it’s not already running, and add your new private SSH key to its registry. Enter the passphrase you used when creating the key when asked.
eval $(ssh-agent -s) && \ ssh-add /home/ec2-user/.ssh/id_rsa
