What is kubero?

What it is

Kubero is a self-hosted Platform as a Service for the Kubernetes ecosystem. It is written in TypeScript and released under the GPL-3.0 license. It gives developers a web-based control layer for deploying applications on Kubernetes without specialized platform knowledge. It follows twelve-factor principles and can run services from existing container images or source code.

The concrete problem Kubero solves is the gap between application deployment and Kubernetes administration. Instead of requiring users to write Helm charts, manage manifests, or operate separate pipelines, Kubero provides an application-centered workflow. It can deploy containers, manage staging environments, connect add-ons including databases and message queues, and expose logs, metrics, and a web console through one interface. This suits teams wanting a Heroku-like experience while retaining control over their Kubernetes infrastructure.

Key capabilities

  • Kubero deploys Docker containers on Kubernetes without Helm charts and supports source-based builds.
  • It includes more than 160 application templates for popular services such as WordPress and Grafana.
  • The platform provides CI/CD pipelines with up to four staging environments per application and automatic redeployments on branch or tag pushes.
  • GitOps review apps are built, started, and cleaned up when pull requests are opened or closed.
  • Add-ons such as PostgreSQL, Redis, MySQL, MongoDB, RabbitMQ, CouchDB, and Haraka Mail Server can be deployed alongside applications.
  • Users can monitor metrics and logs, use a web console, and receive Discord, Slack, or webhook notifications.
  • Kubero supports GitHub and OAuth2 single sign-on, basic authentication, scheduled tasks, vulnerability scans, and multi-tenancy.

Who uses it and how

  • Development teams use Kubero as an internal developer platform, letting application owners deploy services without Kubernetes specialization.
  • Product teams use review-app workflows to create temporary environments for pull requests and remove them when those requests close.
  • Operations teams use the API and CLI to connect Kubero to CI/CD workflows, while the web UI provides logs, metrics, restarts, and console access.
  • Multi-tenant organizations use Kubero to separate teams or customers, authenticate users through GitHub or OAuth2, and deploy databases or message queues alongside workloads.

Getting started

Kubero is installed into an existing Kubernetes cluster by running its UI and operator containers; a demo instance is available at https://demo.kubero.dev.

When to use it — and when not to

Kubero fits teams that want a self-hosted, Kubernetes-native alternative to Heroku, Netlify, Coolify, Vercel, Dokku, or Portainer and can operate the underlying cluster. It stores all data in Kubernetes etcd without an extra database, simplifying setup but placing backup, upgrade, and recovery responsibility on the self-hoster. It may be less suitable for users who cannot operate Kubernetes, require a separate application database, or prefer a tool that does not depend on a Kubernetes instance.

Kubero [pronounced: Kube Hero] is a self-hosted PaaS (Platform as a Service) that allows any developer to deploy their application on Kubernetes without specialized knowledge. Kubero follows the principles of 12-factor apps. It is possible to run apps based on existing containers or from source code.

Basic Concept

Kubero is Kubernetes native and runs with two containers on any Kubernetes instance (kubero-ui and Operator). All data is stored on your Kubernetes etcd without an extra database.

164+ Application templates (similar to Heroku Buttons)

Quickstart

1) Download and unpack the Kubero CLI (MacOS, Linux, Windows)

Binaries (MacOS, Linux)

$ curl -fsSL get.kubero.dev | bash

Brew (MacOS, Linux)

$ brew tap kubero-dev/kubero
$ brew install kubero-cli

2) Run kubero install to install all components on a new or your existing cluster

You can bring your own existing cluster or create one with the kubero install on one of the following providers:

  • GKE
  • Scaleway
  • DigitalOcean
  • Linode
  • Kind (local)

Supported GIT repositories (hosted and self-hosted)

  • Gitea / Forgejo
  • Gogs
  • Github
  • Gitlab
  • Bitbucket

Tested languages/frameworks

Basically everything that can be packaged in a single container can be deployed by Kubero.

  • GoLang (including Hugo, gin-gonic)
  • Python (including Flask)
  • JavaScript/NodeJS
  • PHP (including Laravel)
  • Ruby (including Rails)
  • Static HTML
  • Rust (including Rocket)
  • ...

How GitOps Works

  1. Create a pipeline with the phases you need (review, test, stage, production)
  2. (optional) Connect the pipeline to your git repository (GitHub, Bitbucket, GiLab, Gitea, Gogs)
  3. Configure your apps with cronjobs and addons

Kubero starts now building your app. Once the build is complete, Kubero will launch the final container and make it accessible via the configured domain.
