I'm building a platform for deploying containerized apps, what should I use?

If you’re building a platform for deploying containerized apps, the best choice depends on how much control you want versus how much you want to offload.

Good options by category

1. Kubernetes

Best if you want a full container orchestration platform with strong ecosystem support.

• Use it if: you need scaling, rolling updates, service discovery, self-healing, multi-service deployments, and long-term flexibility.
• Pros: industry standard, huge ecosystem, works across clouds/on-prem, lots of tooling.
• Cons: operational complexity, steep learning curve.

Best for: serious platform products, multi-tenant systems, teams expecting growth.

2. HashiCorp Nomad

Best if you want something lighter and simpler than Kubernetes.

• Use it if: you want orchestrating containers and maybe also non-container workloads without Kubernetes complexity.
• Pros: simpler ops, easy to run, integrates well with Consul/Vault.
• Cons: smaller ecosystem, less common for container platform products.

Best for: smaller teams or platforms that value simplicity.

---

3. Docker Swarm

Best if you want very simple orchestration, but generally not ideal for new platforms.

• Use it if: you want minimal complexity and already know Docker well.
• Pros: easy to learn, simple setup.
• Cons: limited ecosystem, less future-proof, declining adoption.

Best for: small internal setups, not usually for a modern platform product.

4. Platform-as-a-Service building blocks

If you’re building a developer platform, you might want to avoid exposing raw orchestration directly.

Examples:

• Kubernetes + Helm/Argo CD
• Kubernetes + Knative for serverless-style deployments
• Kubernetes + Crossplane for managing infra resources
• Fly.io / Render / Cloud Run style architecture if you want a more opinionated PaaS

Best for: a product that hides infra complexity from users.

My recommendation

If you’re creating a platform for deploying containerized apps, start with Kubernetes unless you have a strong reason not to.

A common stack is:

• Kubernetes for orchestration
• Helm or Kustomize for packaging
• Argo CD or Flux for GitOps deployment
• Ingress controller like NGINX, Traefik, or Gateway API
• Prometheus + Grafana for observability
• Cert-manager for TLS
• External Secrets / Vault for secrets

Simple decision rule

• Want the most standard, scalable choice → Kubernetes
• Want simpler ops → Nomad
• Want lowest complexity → Managed PaaS approach or cloud service like Cloud Run / ECS / App Runner

If you want, I can also recommend a stack based on:

1. your team size,
2. cloud provider,
3. whether you need multi-tenancy,
4. and whether this is an internal tool or a commercial platform.
