Setup HashiCorp Consul


You can run Consul locally using Docker:

docker run -d --name=dev-consul -e CONSUL_BIND_INTERFACE=eth0 consul

You can then interact with the server using localhost:8500.


The easiest way to install Consul on Kubernetes is by using the Helm chart:

helm install consul stable/consul

This installs Consul into the default namespace. To interact with Consul, find the service with: kubectl get svc consul.

For example, if installing using the example above, the Consul host address would be:

consul.default.svc.cluster.local:8500
