    {
      "action": "aws:runShellScript",
      "name": "runShellScript",
      "inputs": {
        "runCommand": ["echo Hello from SSM Run Command"]
      }
    }
  ]
}'

aws ssm create-association --name "MyAssociation" --targets "Key=InstanceIds,Values=i-1234567890abcdef0,i-abcdef01234567890" --schedule-expression "price(5 mins)"
