MiniCD

Package minicd exposes an http.HandlerFunc that you can include in your Go web server so it can continuously deliver itself whenever you push to Github.

This is meant for small personal projects and I wouldn't recommend it for large production apps. For larger scale CI/CD check out baghdad.

Usage

package main

import (
    "context"
    "fmt"
    "net/http"

    "github.com/marwan-at-work/minicd"
)

func main() {
    killSig := make(chan context.Context)

    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintln(w, "hello world")
    })

    http.HandleFunc("/github-hook", minicd.Handler(minicd.Config{
        WebhookSecret: "my_webhook_secret",
        GithubToken: "optional_if_public_repo",
        KillSig: killSig,
    }))

    srv := &http.Server{Addr: ":3000"}

    go func() {
        if err := srv.ListenAndServe(); err != nil && err != http.ErrServerClosed {
            log.Fatal(err)
        }
    }()

    err := srv.Shutdown(<-killSig)
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println("see ya on the other updated side")
}

Gotchas

This doesn't work with a local Docker container because spinning a new process inside the container doesn't keep the container alive if the original process was killed.

As a to-do, this could work with a swarm cluster.
