dokku
Dokku is a self-hosted, Docker-based platform-as-a-service (PaaS) that simplifies application deployment and lifecycle management without requiring Kubernetes expertise. It provides Heroku-like workflows on your own infrastructure, supporting multiple buildpacks and deployment targets.

What dokku is
Dokku is a Shell-based orchestration layer around Docker that automates app builds, deploys, and scaling via git pushes and command-line operations. It abstracts container management and supports buildpacks, multiple process types, and integration with external schedulers like Nomad.

Best use cases
Implementation considerations
- Requires a fresh Ubuntu 22.04/24.04 or Debian 11+ VM; plan for OS selection and cloud/datacenter provisioning before installation.
- SSH key management is mandatory for deployment; ensure keypair generation and rotation policies are in place.
- Single-point-of-failure by design on a single server; consider backup strategies, snapshots, and failover procedures early.
- Buildpack selection and app Procfile configuration determine deployment success; test locally and validate before pushing to production.
- Persistent storage (databases, caches) requires external services or manual Docker volume management; plan data architecture upfront.
When to avoid it — and what to weigh
- Requiring enterprise-grade multi-region failover — Dokku is single-server or small multi-node focused; it is not designed for distributed, highly available architectures spanning regions or clouds.
- Needing advanced scheduling and orchestration — If your workload demands fine-grained pod placement, autoscaling policies, or complex service meshes, Kubernetes or managed platforms are better suited.
- Running stateful services at scale — Dokku excels at stateless apps. Heavy database or persistent storage workloads require external managed services or careful custom configuration.
- Strict compliance or air-gapped environments — Deployment relies on Docker image pulls and external package repositories; offline or highly restricted networks will require custom mirroring setup.

Dokku itself does not perform app-level code scanning or vulnerability assessment. Security posture depends on: (1) host OS hardening and patches, (2) Docker daemon security configuration, (3) SSH key protection, (4) isolation of deployment credentials, (5) TLS/SSL certificate management (Dokku supports automatic certs via Let's Encrypt). Multi-tenant deployments on a single Dokku instance share the Docker daemon; container escape or privilege escalation risks inherit from Docker. No built-in secrets management; credentials require careful handling (environment variables, plugin integrations). Audit logging and compliance features are not mentioned; verify against your requirements.
Alternatives to consider
Heroku
Managed alternative requiring no infrastructure management; higher cost and less control. Best if you prioritize simplicity and SLAs over cost.
Kubernetes (self-hosted or managed)
More powerful orchestration with advanced scheduling, multi-region support, and ecosystem. Steeper learning curve and operational overhead; use if you need enterprise-scale complexity.
Fly.io or Railway
Modern managed platforms with git-push deployment, edge deployment, and simpler ops. Vendor lock-in and pricing trade-offs; consider if you want managed simplicity with some provider flexibility.
