Usage no npm install needed!

Express Git Manage

CAUTION: Under active development, not suitable for production use for people outside the development team yet.


You configure the container by setting environment variables:

  • DIR - The directory containing the git repositories
  • KEYS_DIR - The directory containing the authorized_keys file
  • GIT_DOMAIN - The SSH domain (optionally including port) to be displayed to users for cloning the repo over SSH e.g.
  • GIT_HTTP_URL - The HTTP/HTTPS base URL (optionally including port) to be displayed to users for cloning the repo over HTTP/HTTPS e.g. Should not end with a /. If not set, this app will attempt to choose a sensible default.
  • MUSTACHE_DIRS - A : separated list of paths the system should look for mustache templates before using its default ones.
  • DISABLE_AUTH - Defaults to false but can be true to make file uploading and downloading work without requiring sign in. Only recommended for development.
  • SCRIPT_NAME - The base URL at which the app is hosted. Defaults to "" and must not end with /. Usually this is set to something like /upload
  • DEBUG - The loggers you want to see log output for. e.g. express-git-manage,express-mustache-jwt-signin.
  • PORT - The port you would like the app to run on. Defaults to 80.
  • SECRET - The secret string used to sign cookies. Make sure this is a long secret that no-one else knows, otherwise they could forge the user information in your cookies. Make sure you set the SECRET variable to the same value in the signin container too, otherwise they won't recognose each other's cookies.

Docker Example

Make sure you have installed Docker and Docker Compose for your platform, and that you can customise your networking so that www.example.localhost can point to

Also, make sure you have the source code:

git clone
cd express-git-manage

Tip: You can also use the published docker image at if you change the docker-compose.yml file to use image: thejimmyg/express-git-manage:0.1.0 instead of building from source

OK, let's begin.

For local testing, let's imagine you want to use the domain www.example.localhost.

You can create certificates as described here:

You'll need to put them in the directory domain/www.example.localhost/sni in this example. Here's some code that does this:

mkdir -p domain/www.example.localhost/sni
openssl req -x509 -out domain/www.example.localhost/sni/cert.pem -keyout domain/www.example.localhost/sni/key.pem \
  -newkey rsa:2048 -nodes -sha256 \
  -subj '/CN=www.example.localhost' -extensions EXT -config <( \
   printf "[dn]\nCN=www.example.localhost\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:www.example.localhost\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")

Now edit your /etc/hosts so that your domain really points to for local testing. You should have a line that looks like this:	localhost www.example.localhost example.localhost

There is already a user file in users/users.yaml which the signin container can use. Edit it to change the usernames and passwords as you see fit.

Tip: You can use a hased password too for the password field. Just visit /user/hash once the example is running to generarte the hash and then update the file.

Make a directory where you can override the default templates that are in views:

mkdir -p views-gitmanage

Make an repo directory where files will be uploaded to:

mkdir -p repo
# Allow other containers to write to it
chmod a+r repo
chmod a+w repo

Make a keys directory and an empty authorized_keys file:

mkdir -p keys
touch keys/authorized_keys

Create a hostkeys directory:

mkdir -p hostkeys

Create an empty git repo named test inside the repo directory for the server to find:

git init --bare repo/test.git

Make sure you change the SECRET variable everywhere, otherwise someone could forge your cookies and gain access to your system. You must use the same value for SECRET in each of the containers otherwise they won't recognose each other's cookies.

You can now run the containers with:

npm run docker:run:local

Visit https://www.example.localhost/. You'll probably need to get your browser to accept the certficate since it is a self-signed one, then you'll be asked to sign in using the credentials in users/users.yml.

As long as the user you sign in with has the admin: true claim in the users/users.yaml file, you should be able to manage git repos.

Make any tweaks to templates in views-gitmanage so that the defaults aren't affected. You can copy the defaults in the views directory as a starting point, but make sure you keep the same names.

You can also check the PUBLIC_FILES_DIRS overlay at https://www.example.localhost/user/public/hello.txt

When you are finished you can stop the containers with the command below, otherwise Docker will automatically restart them each time you reboot (which is what you want in production, but perhaps not when you are developing):

npm run docker:stop:local


You will need git installed locally. It is used by the post-update hook in the repos that this interface creates to allow git repos to be shared over HTTP(S).

npm install DISABLE_AUTH=true DISABLED_AUTH_USER='{"admin": true, "username": "disableduser"}' SIGN_IN_URL=/user/signin SCRIPT_NAME="" DEBUG=express-git-manage,express-mustache-overlays,express-mustache-jwt-signin DIR=repo KEYS_DIR=keys PORT=8000 SECRET='reallysecret' npm start

Visit http://localhost:8000.

You should be able to make requests to routes restricted with signedIn middleware as long as you have the cookie, or use the JWT in an `Authorization header like this:

Authorization: Bearer <JWT goes here>

A good way of organising this is to use gateway-lite as your gateway proxying both to express-mustache-jwt-signin and this module. Then you can use express-mustache-jwt-signin to set the cookie that this project can read as long as the SECRET environmrnt variables are the same.

If you just enable SECRET but don't set up the proxy, you'll just get redirected to the SIGN_IN_URL (set to /user/signin in the example) and see a 404 page.
