Troubleshooting Systems Manager Run Command - AWS Systems Manager
If your instances don't show up on SSM service console check the following:

- If using non admin/account owner users (i.e. IAM users) check if they have the right policies attached to them.
- Do the EC2 instances in question have SSM Agent software installed on them
- Do the EC2 instances in question have the Role containing the policy named AmazonEC2RoleforSSM attached to it and, if so, has the instance been restarted after having the role attached to it?
- Is type of command that is being run available for the OS in question

Configuring Access to Systems Manager - AWS Systems Manager
To be able to use AWS SSM service on EC2 instances (which allows one to run shell scripts by having AWS invoke script execution directly) you need to configure the users invoking the ssm service directly with the right policies and configure the EC2 instances with the proper roles.

Using aws-cli --query Option To Simplify Output -
Nice little tutorial demonstrating how to capture AWS command output from Bash Shell scripts into variables to use in scripts.

e.g. Get the status of an RDS Instance e.g. started, stopped, starting, stopping, modifying that sort of thing. You can do it like this:

rds_instance_status=$(aws --profile my-profile rds describe-db-instances --db-instance-identifier helis-staging-rds-instance-1 --query 'DBInstances[0].DBInstanceStatus')

Note that the query option drills down the output, which, by default is returned as JSON text.

How to use Python Boto3 to list Instances in Amazon AWS – Super Library of Solutions
Shows a simple example of how to begin using boto3 library for Python in the simplest of ways.

When reading through the library it's not very clear from the get go how to select a saved profile your ~/.aws/credentials directory which you create when you install the awscli tool into your development machine and configure with $ aws configure command. So here's how you quickly select a profile to create a session for boto3 and then create an s3 client for example.

session = boto3.Session(profile_name='my-profile-name')

s3_client = session.client('s3')

Now with your client you run commands. For example, to list all buckets run:

This looks promising but parts of it are kind of cumbersome to get started. Namely, having to install a root / self-signed SSL certificate and getting the browsers, namely Google Chrome, to honor it just for the development mode.

Shopify/slate: Slate is toolkit for developing Shopify themes. It is designed to assist your workflow and speed up the process of developing, testing, and deploying themes to Shopify stores.
This looks promising. I tried it. However, the development mode with the local browser (localhost:8080) feature is kind of broken since you have to get your browsers to trust a self signed certificate and that's a pain in the ass.
