brainstorming-docker-net.md

Container layering

# Name Description
1 WindowsServerCore Made and Versioned by Microsoft
2 App Dependencies IIS/Websockets/ARR/.Net 4.6/VSRuntime...ect - Made and versioned by [My Company] patched adhoc
3 Release Bits for Application Created as part of build process image per release/build.
4 Enviornment / Tenant specific Configuration Contains configuration files for that tenant release combination using octopus variable replacement - Created by Octopus Deploy (because this contains tenant configuration). It is not a onetime process but rather updated as we push out deployments.

Build/CI/Cd Pipeline

  1. Build runs outputs: nuget packages, pushes to octopus server,creates a release, creates docker images #3 from above
  2. Octopus deploys appliction to an environment/tenant combination. Outputs: runs variable transformations and replacements on configuration files. executes a docker build adding those files to a specific folders per deployment package.
  3. Deployment corridnates build of docker images, running migration steps, and running new containers(possibly by delegating to docker datacenter or swarm, ect)
