Consul has many integrations with Kubernetes. You can deploy Consul to Kubernetes using the Helm chart, sync services between Consul and Kubernetes, run Consul Connect Service Mesh, and more. This section documents the official integrations between Consul and Kubernetes.

» Use Cases

Running a Consul server cluster: The Consul server cluster can run directly on Kubernetes. This can be used by both nodes within Kubernetes as well as nodes external to Kubernetes, as long as they can communicate to the server nodes via the network.

Running Consul clients: Consul clients can run as pods on every node and expose the Consul API to running pods. This enables many Consul tools such as envconsul, consul-template, and more to work on Kubernetes since a local agent is available. This will also register each Kubernetes node with the Consul catalog for full visibility into your infrastructure.

Consul Connect Service Mesh: Consul can automatically inject the Consul Connect sidecar into pods so that they can accept and establish encrypted and authorized network connections via mutual TLS. And because Connect can run anywhere, pods can also communicate with external services (and vice versa) over a fully encrypted connection.

Service sync to enable Kubernetes and non-Kubernetes services to communicate: Consul can sync Kubernetes services with its own service registry. This allows Kubernetes services to use native Kubernetes service discovery to discover and connect to external services registered in Consul, and for external services to use Consul service discovery to discover and connect to Kubernetes services.

And more! Consul can run directly on Kubernetes, so in addition to the native integrations provided by Consul itself, any other tool built for Kubernetes can choose to leverage Consul.

» Getting Started With Consul and Kubernetes

There are several ways to try Consul with Kubernetes in different environments.
