# Setup Consul
|
|
|
|
## Locally
|
|
|
|
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`.
|
|
|
|
## Kubernetes
|
|
|
|
The easiest way to install Consul on Kubernetes is by using the [Helm chart](https://github.com/helm/charts/tree/master/stable/consul):
|
|
|
|
```
|
|
helm install consul stable/consul
|
|
```
|
|
|
|
This will install 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`
|
|
|
|
## Create a Dapr component
|
|
|
|
The next step is to create a Dapr component for Consul.
|
|
|
|
Create the following YAML file named `consul.yaml`:
|
|
|
|
```yaml
|
|
apiVersion: dapr.io/v1alpha1
|
|
kind: Component
|
|
metadata:
|
|
name: <NAME>
|
|
namespace: <NAMESPACE>
|
|
spec:
|
|
type: state.consul
|
|
metadata:
|
|
- name: datacenter
|
|
value: <REPLACE-WITH-DATA-CENTER> # Required. Example: dc1
|
|
- name: httpAddr
|
|
value: <REPLACE-WITH-CONSUL-HTTP-ADDRESS> # Required. Example: "consul.default.svc.cluster.local:8500"
|
|
- name: aclToken
|
|
value: <REPLACE-WITH-ACL-TOKEN> # Optional. default: ""
|
|
- name: scheme
|
|
value: <REPLACE-WITH-SCHEME> # Optional. default: "http"
|
|
- name: keyPrefixPath
|
|
value: <REPLACE-WITH-TABLE> # Optional. default: ""
|
|
```
|
|
|
|
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here](../../concepts/secrets/README.md)
|
|
|
|
The following example uses the Kubernetes secret store to retrieve the acl token:
|
|
|
|
```yaml
|
|
apiVersion: dapr.io/v1alpha1
|
|
kind: Component
|
|
metadata:
|
|
name: <NAME>
|
|
namespace: <NAMESPACE>
|
|
spec:
|
|
type: state.consul
|
|
metadata:
|
|
- name: datacenter
|
|
value: <REPLACE-WITH-DATACENTER>
|
|
- name: httpAddr
|
|
value: <REPLACE-WITH-HTTP-ADDRESS>
|
|
- name: aclToken
|
|
secretKeyRef:
|
|
name: <KUBERNETES-SECRET-NAME>
|
|
key: <KUBERNETES-SECRET-KEY>
|
|
...
|
|
```
|
|
|
|
## Apply the configuration
|
|
|
|
### In Kubernetes
|
|
|
|
To apply the Consul state store to Kubernetes, use the `kubectl` CLI:
|
|
|
|
```
|
|
kubectl apply -f consul.yaml
|
|
```
|
|
|
|
### Running locally
|
|
|
|
To run locally, create a `components` dir containing the YAML file and provide the path to the `dapr run` command with the flag `--components-path`.
