emc
The minimally declarative service catalog.
Pronounced "MC" as in the master of ceremonies.
Background
In the last three jobs I've worked at, it's always been a hassle to trying to locate the various dashboards, documentation, and support for a given project. I joined effx to try and help address just that. As I've been spinning up a new cluster, I found myself wanting a landing page for the systems that I use regularly.
Building your catalog
The emc service catalog is defined using a simple Golang script. This makes it easy for engineers to drop in their
own functionality for rendering links, link groups, or services. For an example, see the provided grafana package
which includes several of my personal dashboards for different systems.
// catalog.go
//go:build ignore
// +build ignore
package main
import (
"github.com/mjpitz/emc/catalog"
"github.com/mjpitz/emc/catalog/grafana"
"github.com/mjpitz/emc/catalog/linkgroup"
"github.com/mjpitz/emc/catalog/service"
)
func main() {
catalog.Serve(
catalog.Service(
"Drone",
service.LogoURL("https://path/to/drone-logo.png"),
service.URL("https://drone.example.com"),
service.Description("Drone is a self-service Continuous Integration platform for busy development teams."),
service.Metadata("Contact", "drone@example.com"),
service.LinkGroup(
"Dashboards",
linkgroup.Link("Drone", grafana.Drone("cicd", "drone")),
linkgroup.Link("Golang", grafana.Golang("cicd", "drone")),
linkgroup.Link("Litestream", grafana.Litestream("cicd", "drone")),
linkgroup.Link("Redis Queue", grafana.Redis("cicd", "drone-redis-queue")),
),
service.LinkGroup(
"Documentation",
linkgroup.Link("docs.drone.io", "https://docs.drone.io/"),
),
),
// ...
)
}
Hosting your catalog
Once you've built your catalog, you can easily run a landing page by executing the catalog file.
$ go run ./catalog.go
This starts a web server for you to interact with on localhost:8080. If :8080 is already in use, you can configure
the bind address be passing the -bind_address flag with the desired host and port.
