# Cloud Lab
[Cloud Lab][003] is a Docker based online lab center, it integrates many popular computer
science courses and provides a Docker based experiment environment as-is.
Cloud Lab is open source with no warranty – use at your own risk.
## Quickstart
If really a Linux newbie or simply don't want to spend time on boring installation, buy the instant [Linux Lab Disk](https://shop155917374.taobao.com).
### Install docker
Cload Lab is docker based, please make sure docker environment is installed with [Docker CE][001], Docker CE support Mac, Windows, Ubuntu, Debian, Fedora, CentOS, Azure and AWS, we have tested Cloud Lab with Docker CE in Ubuntu and Mac.
The old install method for Windows and Mac OSX is [Docker Toolbox][002].
### Configure docker
In order to run docker without password, please make sure your user is added in the docker group:
$ sudo usermod -aG docker $USER
In order to speedup docker images downloading, please configure a local docker mirror in `/etc/default/docker`, for example:
$ grep registry-mirror /etc/default/docker
DOCKER_OPTS="$DOCKER_OPTS --registry-mirror=https://docker.mirrors.ustc.edu.cn"
$ service docker restart
In order to avoid network ip address conflict, please try following changes and restart docker:
$ grep bip /etc/default/docker
DOCKER_OPTS="$DOCKER_OPTS --bip=10.66.0.10/16"
$ service docker restart
If the above changes not work, try something as following:
$ grep dockerd /lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H fd:// --bip=10.66.0.10/16 --registry-mirror=https://docker.mirrors.ustc.edu.cn
$ service docker restart
If installed via Docker Toolbox, to access the Lab page, we must get and use the `eth1` ip address, just replace 'localhost' with this ip in the Lab page url:
$ ifconfig eth1 | grep 'inet addr' | tr -s ' ' | tr ':' ' ' | cut -d' ' -f4
192.168.99.100
If the Linux system is installed on Virtualbox by ourselves, to access the Lab page outside, we must add the eth1 network device at first via setting: 'Network -> Adapter2 -> Host-only Adapter'.
### Choose a working directory
If installed via Docker Toolbox, please enter into the `/mnt/sda1` directory of the `default` system on Virtualbox, otherwise, after poweroff, the data will be lost for the default `/root` directory is only mounted in DRAM.
$ cd /mnt/sda1
For Linux or Mac OSX, please simply choose one directory in `~/Downloads` or `~/Documents`.
$ cd ~/Documents
### Download cloud-lab
$ git clone https://github.com/tinyclub/cloud-lab.git
