Helm
Release supports Helm 3 based charts and you can easily mix Docker Compose style services with Helm based services. If you are using Helm for your in-house services Release allows you define builds that can be referenced from your values files. Release also provides environment variables for the generated hostnames and ingress Helm charts to get your application on the Internet.
We recommend Helm when using Release with a large number of micro services. Helm allows you define all of the resources needed and gives additional control of Kubernetes resources for your micro services.
Release allows you to deploy both open source charts from Helm repositories and charts that live within your source control system. The Helm chart definition, shown below, can be used by the workflows in Release to orchestrate the deployment of your application.
