Branch Strategy
- Regularly merge into master branch
- No long-lived feature branches
- Testing happens before the merge
Continuous Integration
- Output container artifacts to private Docker registry
- Output static content artifacts to S3
- Credentials stored in Jenkins, not the code
- Do all work requiring tools in Docker containers
- Use "Jenkinsfile" pipelines defined in the repository
- Similar options in TravisCI, Appveyor, Azure, and more
Spinnaker Pipeline
- Triggered when new image is pushed to Docker registry
- We use Google Container Registry for _catalog support
- Uses the Kubernetes v1 provider (v2 wasn't an option yet)
- Red/Black (aka Blue/Green) Deployment
- Succeeds when Pod liveness and readiness probes pass
- Still balancing the nature of "healthy" for each type
Configuration
- We store most configuration in the repository
- Some configuration is better in Kubernetes
- Connection info for shared infrastructure
- Security credentials, shared keys, etc
- Configuration is applied via env variables in pipelines
- We plan to switch to volume mounts

Spinnaker Pipelines
The UI is really easy to use. You just create a new application, then add a new pipeline. Add all the stages like the others and just tweak the values. Takes a few hours - easy.
What about when we have a few hundred of these of things and we need to change the settings for all of them?
