This is our CD platform. We use TFS for gated-checks and release builds. A release build packages all our components, pushes these packages to Octopus and triggers a release into our Development environment. A suite of integration tests are run and finally if all is successful the team gets a notification on Slack that a new release is available. This can then get promoted through all our non-production environments, Finally, we use offline deployments as we are not yet allowed to promote all the way to production from Octopus. Offline deployments are great as they allow us to retain our tried and tested deployment process but instead, humans become the tentacles when deploying in prod and pre-prod.
