Use StartSession with an AWS SDK or CLI

Example 1: To start a Session Manager session

This start-session example establishes a connection with an instance for a Session Manager session. Note that this interactive command requires the Session Manager plugin to be installed on the client machine making the call.

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

Output:

Starting session with SessionId: Jane-Roe-07a16060613c408b5

Example 2: To start a Session Manager session using SSH

This start-session example establishes a connection with an instance for a Session Manager session using SSH. Note that this interactive command requires the Session Manager plugin to be installed on the client machine making the call, and that the command uses the default user on the instance, such as ec2-user for EC2 instances for Linux.

ssh -i /path/my-key-pair.pem ec2-user@i-02573cafcfEXAMPLE

Output:

Starting session with SessionId: ec2-user-07a16060613c408b5
