-# Docker-Gitserver
-[Docker-Gitserver](https://hub.docker.com/r/uleenucks/gitserver) is a containerized [GIT](https://git-scm.com/) server.
-
-## Requirements
-- [Docker](https://www.docker.com/)
-- [docker-compose](https://www.docker.com/products/docker-compose)
-
-## Usage
-### Starting server
-For the initial start, just run the following:
-
-`docker-compose up -d`
-
-Remember the container id (refered to as `$container`),
-it's printed as `Creating $container`.
-
-### Starting without docker-compose
-If you can't or don't want to use docker-compose, run
-
-```
-docker run -d --name git \
-  -p 22124:22 \
-  -v "${GIT_DATA}:/home/git/repositories" \
-  -e "PUBKEY=$(cat ~/.ssh/id_ed25519.pub)" \
-  uleenucks/gitserver:latest
-```
-
-### Stopping server
-`docker-compose stop`
-
-### Creating a repo on server
-To create a new repo named `$open`, use the following:
-
-#### Open a shell on the server
-`docker exec -it $container sh`
-
-The container name `$container` is printed on startup.
-
-#### Create new repository on server
-```
-create_repo /home/git/repositories/open.git
-```
-
-This will create  ``open.git`` as a new repository on your server
-
-#### Connecting to your git repository
-
-From any client do the following:
-```
-git remote add origin ssh://git@<fqdn>:22124/home/git/repositories/open.git
-```

-- Built using hardening gcc flags.
-- Dynamic TLS records patch (cloudflare).
-- TTP/2 (+NPN) support.
-- Brotli compression support (and configured).
-- AIO Threads support.
-- No unnessary modules (except fastcgi).
-- PCRE-jit enabled.
-- Strong configurations included.
-- Anonymous webserver signature (headers-more).
-
-#### Notes
-- It is required to change the `listen` directive to 8000/4430 instead of 80/443.
-- Linux 3.17+, and the latest Docker stable are recommended.
-
-#### Volumes
-- **/sites-enabled** : vhosts files (*.conf)
-- **/conf.d** : additional configuration files
-- **/certs** : SSL/TLS certificates
-- **/var/log/nginx** : nginx logs
-- **/passwds** : authentication files
-- **/www** : put your websites there
-
-#### Build-time variables
-- **NGINX_VERSION** : version of nginx
-- **GPG_NGINX** : fingerprint of signing key package
-- **BUILD_CORES** : number of cores used during compilation
-
-#### How to use it?
-https://github.com/hardware/mailserver/wiki/Reverse-proxy-configuration
-
-Some configuration files located in `/etc/nginx/conf` are already provided, you can use them with the `include` directive.
-
-- `ssl_params` : Provides a nice balance between compatibility and security.
-- `headers_params` : HSTS (+ preload), XSS protection, etc.
-- `proxy_params` : use with `proxy_pass`.
