I already have a CloudFormation template that launches EC2 instances and an ECS cluster to run a Python-based Docker container. The stack works, but several resources now need tweaks and clean-up rather than wholesale replacement. Once we connect, I’ll share the current template, the running stack’s state, and the change log I’ve collected so you can dive straight in. Scope of work • Update or refactor existing EC2 and ECS resources so the service starts cleanly with every deployment. • Tidy up IAM roles, security groups, and any hard-coded parameters that could be moved to the parameter section. • Align task definitions with the latest Docker image (Python 3.11) and confirm logging/monitoring still flows to CloudWatch. • Validate the modified template through `cfn-lint` and a test deployment in my sandbox account; no regressions or additional manual steps should remain. Deliverable A revised YAML/JSON CloudFormation template, fully commented, plus a short deployment guide that notes any new parameters I need to supply. Please tell me about your hands-on experience editing complex CloudFormation stacks that use EC2 and ECS together, especially where Dockerised Python apps are involved. No lengthy proposals needed—concise, experience-focused replies are perfect.
