Setup HashiCorp Consul
{{< tabs "Self-Hosted" "Kubernetes" >}}
{{% codetab %}} 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
.
{{% /codetab %}}
{{% codetab %}} 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
{{% /codetab %}}
