Passing command once logged through aws ssm start session in AWS CLI

Question

I need to pass "sudo su - < user >" command once i logged though AWS CLI using aws ssm?

aws ssm start-session --target "instance ID"??????? "sudo su - < user >"

Is there any way? Passing as parameters or something?

Answer 1

It is possible to get into an EC2 instance from the command line without SSH. Whenever you can avoid using SSH, and use more cloud-native approaches such as System Manager's Session Manager, that is recommended.

The documentation says:

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

So you can get into your EC2 instance that way, and then enter "sudo su - < user >" .

However, passing in parameters with the aws ssm start-session AWS CLI command is currently not supported, as that same documentation page says:

--parameters (map)
