Session Manager - Simplified

• Alternative login to your ec2 instances via session manager
  • Make sure you are using vm with session manager installed
  • Your instance is attached with a iam role that has following policy attached:
    • policy_arn = “arn:aws:iam::aws:policy/AmazonSSMManagedInstanceCore”
  • Get the instance id from aws and try login with aws-cli as:

    aws ssm start-session --target "i-1234567890abcdef0"
            

    You will get a error, like following:

    SessionManagerPlugin is not found. Please refer to SessionManager Documentation here: http://docs.aws.amazon.com/console/systems-manager/session-manager-plugin-not-found
            

  • Install the plugin first ;) https://docs.aws.amazon.com/systems-manager/latest/userguide/session-manager-working-with-install-plugin.html

    yay -S aws-session-manager-plugin
            

    and retry, you will be able to login.

    Starting session with SessionId: thapakazi-00xxx123
