Tyk distributes all components as OCI-compatible container images, which means they run unchanged on any OCI-compliant runtime: Docker Engine, containerd, CRI-O, or Podman. You do not need to rebuild images when moving between runtimes or cloud providers.
Since Kubernetes v1.24 removed the dockershim compatibility layer, managed Kubernetes services (EKS, GKE, AKS, OpenShift) use containerd or CRI-O directly. Docker is no longer required or present by default on Kubernetes nodes. Tyk’s Helm-based installations work on all of these out of the box.
Supported runtimes
The table below shows the default container runtime for each major provider.
To check the container runtime on your cluster nodes:
Running Tyk locally
Docker
Docker is the fastest way to try Tyk on a laptop or VM. Tyk’s quick starts and demo repositories use Docker Compose by default. See the Docker installation guide for step-by-step instructions.Podman (RHEL 8+)
RHEL 8 ships Podman instead of Docker. Podman is daemonless, rootless-friendly, and uses the same CLI syntax as Docker. Tyk images run on Podman without modification. Running Tyk Gateway with Podman (rootless)::Z suffix is required on SELinux-enabled systems (RHEL, Fedora) to relabel the bind-mounted volume so the container can access it.
Alias Podman as Docker (optional):
If your scripts call docker, you can alias Podman:
Docker Compose and Podman Compose
Tyk’s demo repositories use standardcompose.yaml files that work with both Docker Compose and Podman Compose.
Running Tyk in Kubernetes
Use Tyk’s Helm charts for production Kubernetes deployments. The charts work across EKS, GKE, AKS, OpenShift (CRI-O), Rancher, and VMware Tanzu without modification.Building images
Bothdocker build and podman build produce OCI-compliant images that run on containerd, CRI-O, or Docker Engine without modification.
FAQ
Do I need to rebuild Tyk images when moving from Docker to containerd or CRI-O?
Do I need to rebuild Tyk images when moving from Docker to containerd or CRI-O?
No. Docker-built images are OCI images and run unchanged on containerd and CRI-O.
Does Podman change how Tyk runs?
Does Podman change how Tyk runs?
Functionally, no. Images are identical. On RHEL, apply SELinux volume labels (
:Z / :z) to bind mounts and be aware of rootless defaults.Can I use Docker Compose files with Podman?
Can I use Docker Compose files with Podman?
Yes. Use
podman compose or point Docker Compose at Podman’s Docker-compatible socket. See the Podman documentation for details.How do I check which runtime my cluster uses?
