start-session

Description

Initiates a connection to a target (for example, an instance) for a Session Manager session. Returns a URL and token that can be used to open a WebSocket connection for sending input and receiving outputs.

Note

AWS CLI usage: start-session is an interactive command that requires the Session Manager plugin to be installed on the client machine making the call. For information, see Install the Session Manager Plugin for the AWS CLI in the AWS Systems Manager User Guide .

AWS Tools for PowerShell usage: Start-SSMSession is not currently supported by AWS Tools for PowerShell on Windows local machines.

See 'aws help' for descriptions of global parameters.

Synopsis

  start-session
--target <value>
[--document-name <value>]
[--parameters <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--target (string)

The instance to connect to for the session.

--document-name (string)

The name of the SSM document to define the parameters and plugin settings for the session. For example, SSM-SessionManagerRunShell . If no document name is provided, a shell to the instance is launched by default.

--parameters (map)

Reserved for future use.

Shorthand Syntax:

KeyName1=string,string,KeyName2=string,string

JSON Syntax:

{"string": ["string", ...]
  ...}

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

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
