Watch the recording at https://www.youtube.com/watch?v=23vb4XsN4Vg How to enable parallel testing of feature branches in isolation without having to timeshare on shared QA infrastructure. This facilitates the test/develop/test lifecycle to continue without interruption. In this talk, we want to retrospectively talk about our approach and have an open discussion on how could tailor to your use case.

2. Creating JIT QA Environments

3. What we’re trying to solve...
“Provide on demand infrastructure to parallelly test
different feature branches while isolating resources
and automating redeploys in order to enable
develop-test(-develop) lifecycle”

4. High-level solution

5. Our solution

6. Grand tour ...
Visit CodeBuild Project

7. Enter branch name

8. Watch the pipeline

9. Access QA instance

10. Deployed to ECS

11. Finally destroy ...

12. Key building blocks (i.e stack)
● Make App
configurable via
environment
variables
● Dockerize App
● Local testing via
docker-compose
● IaC Build / Pipeline
● IaC ECS Cluster +
Traefik
● IaC of creation and
deletion of QA ECS
container instances
● Terraform
workspaces +
remote state
● ECR build script,
configurable via
docker build args.
● ECS task definition
with CPU/RAM
consideration
● ECS service
definition
● Dynamic config via
docker labels
● Handles routing
http/https requests
● Powerful
middleware if
needed
