tsuru

Tsuru is an open-source Platform as a Service (PaaS) that simplifies application deployment by abstracting away infrastructure management. Developers write code in their language of choice, and tsuru handles containerization, scaling, and add-on resource provisioning across Kubernetes clusters.

What tsuru is

Written in Go, tsuru provides a declarative PaaS layer over Kubernetes, offering multi-language platform support (Python, Node.js, Go, Ruby, PHP, Java, Lua, Perl), add-on marketplace integration, and CLI-driven application lifecycle management. It abstracts Kubernetes complexity while maintaining extensibility through custom platforms and service add-ons.

Quickstart

Get the tsuru source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/tsuru/tsuru.gitcd tsuru# follow the project's README for install & configuration

Best use cases

Multi-language application hosting

Teams building polyglot applications benefit from tsuru's native support for 8+ programming languages with pre-configured platforms and consistent deployment workflows.

Internal developer platform (IDP)

Organizations can deploy tsuru on their Kubernetes infrastructure to provide self-service application deployment and resource management without exposing Kubernetes complexity to developers.

Service add-on ecosystem

Applications needing managed databases, caches (Redis, memcached), or third-party services can leverage tsuru's add-on marketplace for integrated provisioning and lifecycle management.

Implementation considerations

  • Requires running Kubernetes cluster; local development via Minikube is documented but production deployments need stable, multi-node K8s infrastructure with appropriate networking and storage.
  • CLI-driven workflow necessitates developer training on tsuru commands and concepts; team/pool/target mental model differs from raw Kubernetes.
  • Add-on resources (databases, caches) must be pre-provisioned or integrated; evaluate whether to use cloud-native managed services (RDS, ElastiCache) or tsuru add-ons.
  • Platform customization is supported but requires maintaining custom Docker images and tsuru platform definitions; document build and versioning processes.
  • Monitoring and observability integration not clearly detailed in provided data; plan for metrics export, log aggregation, and alerting outside tsuru.

When to avoid it — and what to weigh

  • Kubernetes expertise not available — Tsuru requires operational knowledge of Kubernetes cluster setup, networking, and troubleshooting; it simplifies the developer experience but not cluster administration.
  • Managed PaaS preferred — If operational overhead of maintaining tsuru itself is unacceptable, consider fully managed alternatives like Heroku, AWS Elastic Beanstalk, or cloud-native PaaS services.
  • Single-language standardization — Teams committed to a single language stack with specialized tooling (e.g., Django-only, Spring Boot-only) may find a language-specific platform more aligned than a polyglot abstraction.
  • Legacy or non-containerized workloads — Applications not designed for stateless containerization or requiring persistent local state will face architectural mismatches with tsuru's container-centric model.

Security considerations

No explicit security audit, vulnerability disclosure policy, or penetration test results provided. BSD-3-Clause license does not include security guarantees. Consider: RBAC and Kubernetes network policies for access control, container image scanning before deployment, secret management strategy for database credentials and API keys, and regular tsuru + Kubernetes patching. Evaluate any add-ons for security posture independently.

Alternatives to consider

Heroku

Fully managed PaaS with zero operational overhead, multi-language support, and integrated add-ons; best for teams avoiding infrastructure management entirely.

OpenShift (Red Hat)

Enterprise Kubernetes distribution with built-in PaaS capabilities, support contracts, and tighter Kubernetes integration; suitable for organizations already committed to OpenShift.

Dokku

Lightweight, single-machine PaaS inspired by Heroku; ideal for small teams or hobby projects unwilling to manage Kubernetes complexity.

tsuru FAQ

Does tsuru require Kubernetes expertise from developers?
No for application developers; tsuru abstracts K8s details via CLI and UI. Yes for operations/DevOps teams maintaining the tsuru platform itself—Kubernetes cluster administration is non-negotiable.
Can I run tsuru on my existing Kubernetes cluster?
Yes. Tsuru is deployed as an application on K8s. Provided docs show Minikube (local), GKE (Google Cloud), and likely support other distributions. Requires Kubernetes 1.x (version not specified in provided data); verify compatibility.
What's the cost of running tsuru?
Software is open-source and free. Costs are infrastructure (Kubernetes cluster VMs/resources), managed add-ons (databases, cache), and operational staff time. No licensing fees.
How do I add a new programming language or add-on?
Tsuru platforms are extensible; custom platforms require Docker images and tsuru platform definitions. Add-ons are managed services; integration depends on custom add-on drivers or external service APIs. Documentation at https://docs.tsuru.io/ covers extensibility patterns.
