Learn about the technical architecture of the Coder platform.

Coder is deployed on Kubernetes and includes the following components:

  • Manager: the central authority; provides authentication and supports the Dashboard and an API which you can use to create and interact with Environments
  • Envproxy: the WebSocket proxy to an environment's editor and terminal
  • PostgreSQL: data storage for session tokens, environment information, etc.

Each component runs in its own Kubernetes pod.


Kubernetes NGINX Ingress

Coder deploys an NGINX Kubernetes ingress controller to allocate and route requests to the appropriate service. You can disable this controller in the helm chart if you use your ingress or gateway.

Deployment Options

There are two ways to deploy Coder:

  1. The default installation, which is a non-air-gapped option, using the Kubernetes provider of your choice; you should be able to access Coder resources from this environment freely
  2. A secured, air-gapped option; you can choose to limit access and deploy Coder by first pulling in all of the required resources, or you can choose to whitelist the URLs/IP addresses needed to access Coder resources

Coder cannot be deployed in an air-gapped environment when using the free license tier. If you need to deploy an air-gapped Coder instance please contact our sales department to see about purchasing licenses.
