I am writing bash script to install missing patches on ec2 instance using session manager. I can start the session using script but I am not sure how can I run command on it using script?

    instanceid = "i-098xxxx"

    echo $instanceid
    echo "instance id"

    # Creating AMI 
    echo "-------------------------------Creation AMI-----------------------------------------"
    aws ec2 create-image --instance-id $instanceid --name "test ami" --description "Delete when 
    testing" --no-reboot --profile xyz

    # Start Session Manager
    aws ssm start-session --target $instanceid --profile xyz

 
    # Command to check for critical security patches and update/install it on ec2 instance
    echo "-------------------------------installing missing patches----------------------------- 
    ------------"
    sudo yum update-minimal --sec-severity=critical,important --bugfix

I want to run sudo yum update-minimal --sec-severity=critical,important --bugfix command in ec2 instance using script.

Can someone guide me on this?

As an alternative to using run-command, if for some reason you need to use a session, you can do this by using the AWS-StartNonInteractiveCommand document, for example:

aws ssm start-session \
    --document-name 'AWS-StartNonInteractiveCommand' \
    --parameters '{"command": ["sudo yum -y update amazon-ssm-agent"]}' \
    --target "$instanceid"

To see the other parameters accepted by this document, run

aws ssm describe-document --name AWS-StartNonInteractiveCommand
