# Cloud Lab [Cloud Lab](http://tinylab.org/cloud-lab) 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 ### Install docker Cload Lab is docker based, please make sure docker environment is installed with [Docker CE](https://store.docker.com/search?type=edition&offering=community), 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](https://www.docker.com/docker-toolbox). ### 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 ### Choose a Lab $ tools/docker/choose Current Lab is: linux-lab Available Labs: 1 cs630-qemu-lab 2 linux-0.11-lab 3 linux-lab 4 markdown-lab 5 qing-lab 6 tinylab.org Choose the lab number: 2 2 linux-0.11-lab Download the lab... ### Run the Lab $ tools/docker/run ### Remove the Lab $ tools/docker/rm ### Stop the Lab $ tools/docker/stop ### Start the Lab $ tools/docker/start ### Update everything $ tools/docker/update ### Autostart everything $ tools/docker/autostart ### Run as root without password If get syntax error under `/etc/sudoers*`, please use `pkexec visudo` to fix up it. $ sudo -s $ echo "$SUDO_USER ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/$SUDO_USER
