-A lightweight Git Server Docker image built with Alpine Linux. Available on [GitHub](https://github.com/jkarlosb/git-server-docker) and [Docker Hub](https://hub.docker.com/r/jkarlos/git-server-docker/)
+A lightweight Git Server Docker image built with Alpine Linux. Available on [GitHub](https://github.com/fr123k/git-server-docker) and [Docker Hub](https://hub.docker.com/r/fr123k/git-server-docker/)
 
-!["image git server docker" "git server docker"](https://raw.githubusercontent.com/jkarlosb/git-server-docker/master/git-server-docker.jpg)
+## Use Case
 
-### Basic Usage
+### Local Jenkins use Local Git Repository
 
-How to run the container in port 2222 with two volumes: keys volume for public keys and repos volume for git repositories:
+The major motivation for the local git server docker container is to provide a way for a local jenkins running in docker to use local git repositories instead of github for example.
 
-	$ docker run -d -p 2222:22 -v ~/git-server/keys:/git-server/keys -v ~/git-server/repos:/git-server/repos jkarlos/git-server-docker
+The following steps describe a way to use the local git server in jenkins without changing the github url of the jobs in jenkins. They can still point to the original github respositories.
 
-How to use a public key:
+#### Local DNS
 
-    Copy them to keys folder: 
-	- From host: $ cp ~/.ssh/id_rsa.pub ~/git-server/keys
-	- From remote: $ scp ~/.ssh/id_rsa.pub user@host:~/git-server/keys
-	You need restart the container when keys are updated:
-	$ docker restart <container-id>
-	
-How to check that container works (you must to have a key):
+Setup a domain like `local.github.com` that is then used by jenkins.
 
-	$ ssh git@<ip-docker-server> -p 2222
-	...
-	Welcome to git-server-docker!
-	You've successfully authenticated, but I do not
-	provide interactive shell access.
-	...
+```bash
+echo "192.168.65.2 local.github.com" >> /etc/hosts
+```
 
-How to create a new repo:
+The ip address `192.168.65.2` is specific to your operating system and only works from within a docker container.
+**This ip address work on MacOS.**
 
-	$ cd myrepo
-	$ git init --shared=true
-	$ git add .
-	$ git commit -m "my first commit"
-	$ cd ..
-	$ git clone --bare myrepo myrepo.git
+#### Git Config
 
-How to upload a repo:
+Add or change the `%{JENKINS_HOME}/.gitconfig` with the following setting.
+```
+[url "ssh://git@local.github.com"]
+	insteadOf = https://github.com/
 
-	From host:
-	$ mv myrepo.git ~/git-server/repos
-	From remote:
-	$ scp -r myrepo.git user@host:~/git-server/repos
+[url "ssh://git@local.github.com/"]
+	insteadOf = git@github.com:
+```
 
-How clone a repository:
+#### Local Github Server
+
+Run the docker git server container on the port 22 (sshd) and specify the github account like `fr123k`.
+
+`docker run -p 22:22 -it -v $(PWD)/../:/git-server `**`-e ACCOUNT=fr123k`**` --name github --rm fr123k/git-server-docker`
+
+If something is not as expected check the [Troubleshooting](#Troubleshooting) section.
 
-	$ git clone ssh://git@<ip-docker-server>:2222/git-server/repos/myrepo.git
+## Basic Usage
 
 ### Arguments
 
 * **Expose ports**: 22
 * **Volumes**:
- * */git-server/keys*: Volume to store the users public keys
- * */git-server/repos*: Volume to store the repositories
+	* **/git-server/**: Volume to store the repositories
+* **Environment Variables**:
+	* **ACCOUNT**: Name of the git account
+	* **DEBUG**: If exits enable debug logging of the sshd to the file `/var/log/auth.log`. Useful for troubleshooting
+
+### Git Repository Volume
+
+The volume has to be mounted to /git-server mount point.
+It has to contain the `.keys` folder with all the public keys
+for the ssh authentication.
+
+* -v (local_git_repository):/git-server/
+
+Example mount directory that is above the current one as a git repository.
+
+`docker run -p 2222:22 -it `**`-v $(PWD)/../:/git-server`**` --name github --rm fr123k/git-server-docker`
+
+### Git Account Name
+
+The name of the git repository.
+* -e ACCOUNT=(name of the git account) default: helmet
+
+For example
+`docker run -p 2222:22 -it -v $(PWD)/../:/git-server `**`-e ACCOUNT=fr123k`**` --name github --rm fr123k/git-server-docker`
+
+### Git Account Name
+
+The name of the git repository.
+* -e DEBUG=true
+
+For example
+`docker run -p 2222:22 -it -v $(PWD)/../:/git-server `**`-e DEBUG=true`**` --name github --rm fr123k/git-server-docker`
+
+### Local SSH Git Server
+
+How to run the container in port 22 (sshd).
+
+`docker run -d -p `**`22:22`**` -v ~/git-server/repos:/git-server/ fr123k/git-server-docker/`
+
+### Local Git Repositories
+
+**After adding git repository described below the docker container has to be always restarted.**
+How to create a new repo:
+
+```bash
+mkdir local-git-repo
+cd local-git-repo/
+git init --shared=true
+git add .
+git commit -m "my first commit"
+```
+
+How to upload a repo:
+
+From host:
+```bash
+mv local-git-repo ~/git-server/
+```
+From remote:
+```bash
+scp -r local-git-repo user@host:~/git-server/
+```
+
+How clone a repository:
+
+```bash
+git clone ssh://git@127.0.0.1:22/helmet/local-git-repo.git
+```
+
+## Troubleshooting
+
+### Validate Local SSH Git Server
+
+How to check that container and the authentication keys works.
+`ssh git@127.0.0.1 -p 22`
+The expected output looks like this.
+```
+Welcome to git-server-docker!
+
+Provided to you from
+
+https://hub.docker.com/r/fr123k/git-server-docker/
+https://github.com/fr123k/git-server-docker
+
+You've successfully authenticated, but I do not
+provide interactive shell access.
+Connection to 127.0.0.1 closed.
+```
 
 ### SSH Keys
 
 How generate a pair keys in client machine:
 
-	$ ssh-keygen -t rsa
+```bash
+ssh-keygen -t rsa
+```
 
 How upload quickly a public key to host volume:
 
-	$ scp ~/.ssh/id_rsa.pub user@host:~/git-server/keys
+```bash
+scp ~/.ssh/id_rsa.pub user@host:~/git-server/.keys
+```
+
+## Docker Image
+
+All `make` commands can only be from the folder where the Makefile is located.
+
+### Build
+
+How to build the docker image:
+
+```bash
+make build
+```
+or
+```bash
+docker build -t git-server-docker .
+```
 
-### Build Image
+### Run
 
-How to make the image:
+How to run the image:
 
-	$ docker build -t git-server-docker .
-	
-### Docker-Compose
+```bash
+make REPOSITORIES=$(PWD)/../ ACCOUNT=fr123k git-server
+```
+or
+```bash
+docker run -p 22:22 -it -v $(PWD)/../ :/git-server -e ACCOUNT=fr123k --name github --rm "fr123k/git-server-docker"
+```
