Comparison of Docker Compose, Kubernetes, and Red Hat OpenShift
The comparison of Docker Compose, Kubernetes, and Red Hat OpenShift gives you a better understanding about these platforms and helps you to choose the right platform for your application environment.
HCL™ Accelerate installations on Docker Compose are not supported for production environments. The Docker Compose installation includes security and performance issues. The Docker Compose installation cannot control container runtimes and complex calculations, which impacts multiple UI components. For example, the random import of plug-ins impacts the performance of product features, like the value stream, releases, and API response time.
Kubernetes installations using Helm provides good security and permissions. Kubernetes supports controlling the container runtime and manages complex calculations.
Considering the security and performance practices, use the Kubernetes and Red Hat OpenShift platform installations for best results in production environments. For the supported version of Kubernetes and Red Hat OpenShift platform, see System Requirements.
The following table explains about the basic differences between Docker Compose, Kubernetes, and Red Hat OpenShift:
| Docker Compose | Kubernetes | Red Hat OpenShift | |
|---|---|---|---|
| Function | An open-source platform for building, deploying and managing application containers | An open-source container orchestration system to manage your application services and deployment | An enterprise grade open-source Platform-as-a-Service (PaaS) by Red Hat to accelerate development and deploy your applications |
| Application | Supports single-host environments, making it suitable for local development and testing but less suitable for production deployments | Supports the creation of multi-node clusters, allowing you to distribute your containerized workloads across multiple machines | Supports the creation of multi-node clusters, allowing you to distribute your containerized workloads across multiple machines |
| Security | Limited support for basic security features like defining environment variables and secrets | Robust security features like network policies, Role-Based Access Control (RBAC), and pod security policies | Advanced security features like integrated Identity and Access Management (IAM) and container security scanning |
| Deployment type | Services | Pods, services, and deployment | Pods, services, and deployment |
