gitdeploy

gitdeploy is an app for continuous deployment of static websites.

Features

gitdeploy is intended for use with static websites that are generated after changes are pushed to a Git repository. This works with sites that are being edited in code and tracked in Git. Sites that have their content managed with a headless CMS that pushes to Git are also very well-suited.

gitdeploy supports verified webhooks from Github, Bitbucket, and Gitea.

gitdeploy is written in Go. This means that it's a standalone binary available on all major operating systems and architectures. It provides an API with endpoints that handle webhooks, allow for initiation of builds, and getting the status of builds and build jobs.

gitdeploy comes with a simple interface. The interface be disabled if you don't want to use it.

Usage

gitdeploy run --listen :3000 --serve-path ./public_overrides --exec ./scripts/

Install

You can download gitdeploy from the Github Releases API and place it in your PATH, or install it with Webi:

Mac, Linux:

curl -sS https://webinstall.dev/gitdeploy | bash

Windows 10:

curl -A MS https://webinstall.dev/gitdeploy | powershell

Setup with Deploy Scripts

Start by copying from examples/ to scripts/.

rsync -av examples/ scripts/

scripts/
├── deploy.sh
├── git.example.com/org/go-project/deploy.sh
├── git.example.com/org/node-project/deploy.sh
├── git.example.com/org/mirror-project/deploy.sh
└── promote.sh

The default deploy.sh is sensible - if another deploy.sh exists in a directory with the same repo name as an incoming webhook, it runs it.

The example deploy scripts are a good start, but you'll probably need to update them to suit your build process for your project.

Git Info

These ENVs are set before each script is run:

GIT_DEPLOY_JOB_ID=xxxxxx
GIT_REF_NAME=master
GIT_REF_TYPE=branch
GIT_REPO_OWNER=example
GIT_REPO_NAME=example
GIT_CLONE_URL=https://github.com/example/example

API

GET  /api/admin/jobs

    {
      "success": true,
      "jobs": [
        {
          "job_id":     "xxxx",
          "created_at": "2020-01-01T00:00:00Z",
          "ref":        "0000000",
        }
      ]
    }

POST /api/admin/jobs
  { "job_id": "xxxx", "kill": true }

  { "success": true }

# note: see --help for how to use --promotions
POST /api/admin/promote
  { "clone_url": "https://...", "ref_name": "development" }

  { "success": true, "promote_to": "staging" }

# note: each webhook is different, but the result is to run a deploy.sh
POST /api/admin/webhooks/{github,gitea,bitbucket}

Build

Frontend:

pushd html/
  npm ci
  scripts/build
popd

API:

With GoReleaser:

goreleaser --snapshot --skip-publish --rm-dist

With Golang:

export GOFLAGS="-mod=vendor"

go run -mod=vendor git.rootprojects.org/root/go-gitver/v2
go generate -mod=vendor ./...
go build -mod=vendor .

You can use build tags to remove providers from the build:

go build -mod=vendor -tags nobitbucket,nogithub .

Supported tags are:

nogithub
nobitbucket

Run as a System Service

sudo env PATH="$PATH" \
  serviceman add --name gitdeploy --system \
    --username app -path "$PATH" -- \
    gitdeploy run --exec ./scripts/

Add Webhooks

To add a webhook you'll first need a secret

with node.js:

crypto.randomBytes(16).toString("hex");

Then you'll need to set up the webhook in your platform of choice.

Github

New Webhook: https://github.com/YOUR_ORG/YOUR_REPO/settings/hooks/new

Payload URL: https://YOUR_DOMAIN/api/webhooks/github
Content-Type: application/json
Secret: YOUR_SECRET
Which events would you like to trigger this webhook?
Just the `push` event.
Active: ✅

Bitbucket

Sometimes Bitbucket does not give you the option to specify the (X-Hub-Signature) secret, so you'll have to append an access_token instead. Example:

Title: gitdeploy
URL: https://YOUR_DOMAIN/api/webhooks/bitbucket?access_token=YOUR_SECRET
Triggers: Repository push

How to Generate a Base64 Secret

in your browser:

(async function () {
  var rnd = new Uint8Array(16);
  await crypto.getRandomValues(rnd);
  var b64 = [].slice
    .apply(rnd)
    .map(function (ch) {
      return String.fromCharCode(ch);
    })
    .join("");
  var secret = btoa(b64)
    .replace(/\//g, "_")
    .replace(/\+/g, "-")
    .replace(/=/g, "");
  console.info(secret);
})();
