OpenRun – Declarative Deployments to Docker or Kubernetes

In plain words
OpenRun is a declarative deployment platform designed for teams to deploy internal web applications to Docker, Podman, or Kubernetes. It focuses on simplifying configuration management for this specific use case, using a minimal config format rather than extensive YAML. The platform supports declarative deployments where app sources are fetched from git, allowing teams to manage applications and updates through simple configuration files rather than imperative commands.

In the maker’s words, at launch
I have been building https://github.com/openrundev/openrun for the last few years and recently added Kubernetes support https://openrun.dev/docs/container/kubernetes. OpenRun is a declarative web app deployment platform, built for teams to deploy internal tools. There are many tools which try to simplify application deployments, but not many support declarative deployments. Even if app sources are fetched from git, creating new apps or updating app config requires imperative commands. Kubernetes is the dominant declarative approach, but it takes too much YAML to manage an app with Kubernetes. OpenRun supports a limited use case, deploying web apps for internal users across a team. For that use case, it supports declarative deployments on top of Docker/Podman or Kubernetes, with a very simple config. Some of the unique features of OpenRun are: - All apps have a staging env, code and config changes are staged before being promoted to prod - Supports OIDC/SAML integration, allowing you to control access to apps using RBAC policies - Full solution which handles builds, CD and request routing. Does not require additional tooling like Jenkins/ArgoCD etc OpenRun can run on a single machine, in which case it directly deploys the container to Docker/Podman. When deployed to Kubernetes, OpenRun builds the images using Kaniko and deploys apps as a Kubernetes deployment, using server side apply to make updates. The whole Starlark based config for creating apps is just: app(path="/streamlit/uber", source="github.com/streamlit/demo-uber-nyc-pickups", spec="python-streamlit") # python-streamlit knows how route requests for Streamlit app(path="/myapp", source="github.com/example/example", spec="container") # container spec works for any app which has a Dockerfile While mainly built for teams, OpenRun is the easiest way to deploy web apps and share them with friends and family https://openrun.dev/docs/use-cases/personal/. You can limit who has access to the apps using OAuth authentication.
