It's a split decision.
Choose Docker for container development, local workflows and agent isolation that can move to cloud sandboxes. Its Personal plan is free, with paid per-user plans for more features and usage. Choose Red Hat OpenShift to build and run applications on a managed cloud service or infrastructure you operate. OpenShift subscriptions and cloud billing vary by edition and provider. These tools solve different problems: Docker is a container and agent toolset; OpenShift is an application platform.
01Side by side
| Docker | Red Hat OpenShift | |
|---|---|---|
| Pricing model | Free tier, then per-user plans and per-repo image pricing | Subscriptions or provider-billed managed cloud services |
| Free tier | Personal and DHI Community are free | No free plan; 8-hour ROSA hands-on experience |
| Self-hosting | Local Docker Desktop; cloud sandboxes for agents | Self-managed on infrastructure, cloud, computers or datacenters |
| Integrations | Existing images, registries, CI, Claude, MCP and OCI | AWS, Azure, Google Cloud and IBM Cloud |
| Deployment model | Local containers and local or cloud agent sandboxes | Managed cloud services or self-managed platform |
| Platforms | Mac, Windows and Linux | Web; hybrid-cloud deployment options |
| Limits and scaling | Plan-specific pulls, repos and runtime-minute allowances | Managed-service SLAs; capacity pricing varies |
| CLI and developer tools | Homepage shows `docker agent run` and `sbx run` | Developer console, Pipelines and GitOps |

02Pricing at real usage
Docker has two free starting points: Personal includes one user, one private Docker Hub repo and 100 pulls per hour; DHI Community provides its open-source hardened-image catalog under Apache 2.0. Pro costs $11 per user monthly or $9 billed annually; Team is $16 or $15, and Business is $24 under either option. Those plans include different Docker Scout repo and Testcontainers Cloud minute allowances. Extra Testcontainers minutes cost $3 per 100 minutes, or $4 per 100 on demand. DHI Select starts at $5,000 per repo; Enterprise pricing is custom.
OpenShift has no free plan, but ROSA offers an 8-hour hands-on experience. Managed services are billed through AWS, Azure, Google Cloud or IBM Cloud. The pricing page lists reserved cloud instances from $0.076 per hour on a three-year contract; self-managed subscription pricing varies by sizing and subscription.
03API, SDKs and integration
Docker fits into an existing container workflow: its homepage says teams can keep their images, registries and CI, and describes the platform as OCI-compliant and platform-independent. It also names Claude and MCP in its agent and governance workflows. The homepage shows docker agent run and sbx run commands, and says agents can start locally and move to Cloud Sandboxes.
OpenShift is a broader application platform. Its Container Platform includes a developer console, Serverless, Service Mesh, Pipelines and GitOps. Red Hat lists managed options for AWS, Microsoft Azure, Google Cloud and IBM Cloud, alongside self-managed editions. The vendor pages do not specify API endpoints, SDKs, supported SDK languages or a documentation set for either product; confirm those requirements with the vendors before choosing an integration path. OpenShift's listed cloud integrations make provider choice part of the deployment design.
04Open source, self-hosting and lock-in
Docker's DHI Community catalog includes open-source images under Apache 2.0. That licence statement applies to the catalog; it does not establish that Docker's full platform is open source. Docker describes local development and cloud sandboxes, but not a self-managed Docker service for running its agent governance stack.
OpenShift offers self-managed editions for an organization's infrastructure, cloud, computer or datacenter, as well as managed cloud services. The vendor sells subscriptions, but does not state an OpenShift source licence in its product overview. Docker's OCI-compliance claim and existing-image workflow may help preserve container portability, but they are not a data-export guarantee. Neither vendor describes export procedures or migration effort on these pages. Ask about image, policy, audit-log and workload export before committing to a long-lived deployment.
Questions people ask
What is the difference between OpenShift and Kubernetes?
Kubernetes is the engine named in OpenShift Kubernetes Engine. OpenShift is the broader application platform: its Container Platform edition also lists a developer console, Serverless, Service Mesh, Pipelines and GitOps. Docker is a separate container and agent toolset, not a competing Kubernetes distribution in this comparison.
Is Docker still relevant in 2026?
Yes, for container development and the workflows Docker describes: building, shipping and running applications, using existing images, registries and CI, and developing with Docker Desktop. Its current product scope also includes agent sandboxes, governance and hardened images. It does not replace an application platform such as OpenShift.
What is the Red Hat equivalent of Docker?
OpenShift is not a direct equivalent to Docker. Docker provides container development tools and agent security features. OpenShift is Red Hat's application platform for building, modernizing and deploying applications, with managed cloud services and self-managed editions. Red Hat Quay is included in OpenShift Platform Plus, but the product pages do not frame it as a Docker replacement.
Is Kubernetes replacing Docker?
They address different layers in this comparison. Docker provides container-development workflows and agent sandboxes; OpenShift includes Kubernetes Engine as part of an application platform. The listed products do not establish that Kubernetes replaces Docker, and teams can assess them for different parts of a stack.
