Single and app and data images
===================
How to build and use images yourself
Normally docker uses a single image for one applications.
But GitLab stores repositories and uploads in the filesystem.
This means that upgrades of a single image are hard.
That is why we recommend using separate app and data images.
We'll first describe how to use a single image.
After that we'll describe how to use the app and data images.
Single image
=================
Run the below commands from the GitLab repo root directory.
People using boot2docker should run the commands without sudo.
Build the image with:
```
sudo docker build --tag gitlab-ce docker/single/
```
Run the image with:
```
sudo docker run --detach --name gitlab-ce --publish 8080:80 --publish 2222:22 gitlab-ce
```
You can then go to [http://localhost:8080/](http://localhost:8080/) or [http://192.168.59.103:8080/](http://192.168.59.103:8080/) if you use boot2docker.
You can login with username `root` and password `5iveL!fe`.
Next time, you can just use `sudo docker start gitlab-ce` and `sudo docker stop gitlab-ce`.
Publish the image with:
```bash
sudo docker commit -m "Initial commit" -a "Sytse Sijbrandij" gitlab-ce sytse/gitlab-ce:7.10.1
sudo docker push sytse/gitlab-ce:7.10.1
```
Use the published image with:
```bash
sudo docker pull sytse/gitlab-ce:7.10.1
sudo docker run --detach --name gitlab-ce --publish 8080:80 --publish 2222:22 sytse/gitlab-ce:7.10.1
```
Troubleshoot with:
```
sudo docker run -ti -e TERM=linux --name gitlab-ce --publish 8080:80 --publish 2222:22 sytse/gitlab-ce:7.10.1 bash
/opt/gitlab/embedded/bin/runsvdir-start & gitlab-ctl reconfigure
gitlab-ctl start
```
Build and use app and data images
======================
At this moment GitLab doesn't have official Docker images.
There are unofficial images at the bottom of this document.
But in this section we'll build our own.
For convinience we will use suffix _xy where xy is current version of GitLab.
Build your own based on the Omnibus packages with the following commands.
Run these from the GitLab repo root directory.
People using boot2docker should run it without sudo.

Troubleshooting
=========================
Please see the [troubleshooting](troubleshooting.md) file in this directory.
Publish the images to Dockerhub
Publish app and data images to Dockerhub
=========================
Login to Dockerhub with `sudo docker login` and run the following (replace '7.9.2' with the version you're using and 'Sytse Sijbrandij' with your name):
```bash
sudo docker commit -m "Initial commit" -a "Sytse Sijbrandij" gitlab_app_xy sytse/gitlab-ce:7.9.2
sudo docker push sytse/gitlab-ce:7.9.2
sudo docker commit -m "Initial commit" -a "Sytse Sijbrandij" gitlab-app:7.10.1 sytse/gitlab-app:7.10.1
sudo docker push sytse/gitlab-app:7.10.1
sudo docker commit -m "Initial commit" -a "Sytse Sijbrandij" gitlab_data sytse/gitlab_data
sudo docker push sytse/gitlab_data
```
Use images published to Dockerhub
Use app and data images published to Dockerhub

sudo docker run --name gitlab_data_volume sytse/gitlab_data /bin/true
sudo docker run --detach --name gitlab_app_7_9_2 --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data_volume sytse/gitlab-ce:7.9.2
