# Consul Service Mesh Demos

This repository contains various demonstrations to highlight features and configuration in Consul Service Mesh.

## Docker Compose

**NOTE**: All service registration and central config is automatically applied when running these examples.  

To apply configuration manually you can comment out the `CENTRAL_CONFIG` environment variable in the docker-compose.yml files:

```yaml

  web_envoy:

    image: nicholasjackson/consul-envoy:v1.6.0-v0.10.0

    environment:

      CONSUL_HTTP_ADDR: 10.5.0.2:8500

      CONSUL_GRPC_ADDR: 10.5.0.2:8502

      SERVICE_CONFIG: /config/web_v1.json

#     CENTRAL_CONFIG: "/central_config/web-defaults.hcl;/central_config/api-defaults.hcl;/central_config/api-v1-defaults.hcl;/central_config/api-v2-defaults.hcl;/central_config/api-router.hcl"

    volumes:

      - "./service_config:/config"

      - "./central_config:/central_config"

    command: ["consul", "connect", "envoy","-sidecar-for", "web-v1"]

    network_mode: "service:web"

```

Config can then be manually applied using the following command once you have started the example with `docker-compose up`:

```

$ consul config write config_file.hcl

```

All central config is stored in the `central_config` folder in each example.

### [Traffic Splitting](traffic_split/)

This demonstration shows how traffic can be split between two service instances. This feature could be used for a Canary or Dark deployment testing strategy.

### [Traffic Routing](traffic_routing/)

This demonstration shows how upstream traffic can be routed between two services using HTTP paths.

### [Metrics / Tracing](metrics_tracing/)

This demonstration shows how to configure Consul Service Mesh for Observability.

### [Service Failover](failover/)

This demonstration shows how to failover upstream services to a different datacenter. This feature could be used to main uptime during a partial or regional service outage.

### [Consul Gateways](gateways/)

This demonstration shows how to route traffic to a second Consul Datacenter using Consul Gateways. This feature could be used to route traffic between Virtual Machines and Kubernetes.

### [Exposing Health Checks](expose/)

Example showing how to bypass proxy security to expose Service health checks publicly.
