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?
The AWS Systems Manager Session Manager provides an SSH-like connection via a web browser.
However, if you wish to automate the execution of commands on instances, you should use the AWS Systems Manager Run Command, which can run commands on a single instance or hundreds of instances, and return results from each run.
