Deployment Model

The Velocitas project uses a common deployment model. It uses OCI-compliant containers to increase the flexibility for the support of different programming languages and runtimes, which accelerates innovation and development. OCI-compliant containers also allow for a standardized yet flexible deployment process, which increases the ease of operation. Using OCI-compliant is portable to different architectures as long as there is support for OCI-compliant containers on the desired platform (e.g., like a container runtime for arm32, arm64 or amd64).

Guiding principles

The deployment model is guided by the following principles

• Applications are provided as OCI-compliant container images.
• The container runtime offers a Kubernetes-compatible control plane and API to manage the container lifecycle.
• Helm charts are used as deployment descriptor specification.

The template projects provided come with a pre-configured developer toolchain that accelerates the development process. The developer toolchain ensures an easy creation through a high-degree of automation of all required artifacts needed to follow the Velocitas principles.

Testing your container during development

The Velocitas project provides for developers a repository template and devcontainer that contains everything to build a containerized version of your app locally and test it. Check out our tutorial e.g., for the Python template to learn more.

Automated container image builds

Velocitas uses GitHub workflows to automate the creation of your containerized application. A workflow is started with every increment of your application code that you push to your GitHub repository. The workflow creates a containerized version of your application and stores this container image in a registry. Further actions are carried out using this container (e.g., integration tests).

The workflows are set up to support multi-platform container creation and generate container images for amd64 and arm64 out of the box. This provides a great starting point for developers and lets you add additional support for further platforms easily.
