Connecting to AWS EC2 instances via Session Manager

April 1, 2021 Leave a comment

When folks have needed command line access to instances running in Amazon Web Service‚Äôs EC2 service, SSH has been the usual method used. However, in addition to using SSH to connect to EC2 instances in AWS, it is also possible to connect remotely via Session Manager, one of the services provided by AWS’s Systems Manager tool.

Session Manager uses the Systems Manager agent to provide secure remote access to the Mac’s command line interface without needing to change security groups and allow SSH access to the instance. In fact, Session Manager allows remote access to EC2 instances which have security groups configured to allow no inbound access at all. For more details, please see below the jump.

Resizing an AWS macOS EC2 instance’s boot drive to use all available disk space

I’ve started working with Amazon Web Service’s new macOS EC2 instances and after a while, I noticed that no matter how much EBS drive space I assigned to a EC2 instance running macOS, the instance would only have around 30 GBs of usable space. In this example, I had assigned around 200 GBs of EBS storage, but the APFS container was only using around 30 GBs of the available space.

After talking with AWS Support, there’s a fix for this using APFS container resizing. This is a topic I’ve discussed previously in the context of resizing boot drives for virtual machines. For more details, see below the jump.
