In order to test certain setups for our metrics visualizations we need to be able to setup several different `ui_config` settings during development/testing. Generally in the UI, we use the Web Inspector to set various cookie values to configure the UI how we need to see it whilst developing, so this PR: 1. Routes `ui_config` through a dev time only `CONSUL_UI_CONFIG` env variable so we can change it via cookies vars. 2. Adds `CONSUL_METRICS_PROXY_ENABLE`, `CONSUL_METRICS_PROVIDER` and `CONSUL_SERVICE_DASHBOARD_URL` so it's easy to set/unset these only values during development. 3. Adds an acceptance testing step so we can setup `ui_config` to whatever we want during testing. 4. Adds an async 'repository-like' method to the `UiConfig` Service so it feels like a repository - incase we ever need to get this via an HTTP API+blocking query. 5. Vaguely unrelated: we allow cookie values to be set via the location.hash whilst in development only e.g. `/ui/services#CONSUL_METRICS_PROXY_ENABLE=1` so we can link to different setups if we ever need to. All values added here are empty/falsey by default, so in order to see how it was previously you'll need to set the appropriate cookies values, but you can now also easily preview/test the the metrics viz in different/disabled states (with differing `ui_config`)
Consul 
- Website: https://www.consul.io
- Tutorials: HashiCorp Learn
- Forum: Discuss
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Consul provides several key features:
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Mesh/Service Segmentation - Consul Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections without being aware of Connect at all.
-
Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
-
Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
-
Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.
Consul runs on Linux, Mac OS X, FreeBSD, Solaris, and Windows. A commercial version called Consul Enterprise is also available.
Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
