Cloud Ubuntu

This project aims to build a basic docker image with Ubuntu + ssh/gateone/noVNC, it should be available easily from all over the world.

ssh, traditional ssh protocol, require ssh client, support graphic/console
noVNC, remote graphic desktop via web browser, platform independent
gateone, web ssh client, platform independent

It is based on:

It is functional, scalable, minimal but with necessary security enhancement:

fail2ban for ssh login failure limitation.
https for noVNC: noVNC/utils/self.pem from gen_pem.sh
https for Gateone
https/http switch with LAB_SECURITY

People can build their own cloud environment with:

# FROM tinylab/cloud-ubuntu

To customize the key/cert, please rerun gen_pem.sh.

Usage

$ ./build                 # build it from scratch
$ ./rm                    # remove the container before run a new one
$ ./run                   # run a new container

The ssh/noVNC/gateone login password can be set via the according environment variables in ./run: UNIX_PWD, VNC_PWD, the default users and passwords are ubuntu.

Services

Protocol	Internal port	Default External port
ssh	22	2222
gateone/webssh	443	4433
noVNC	6080	6080

VNC/ssh Web Proxy

To save the ports and processes resources, the original noVNC and Gateone support have been removed from cloud-ubuntu and a standalone noVNC and Gateone proxy image is created and named with cloud-ubuntu-web and it can be run with:

$ ./scripts/web-ubuntu.sh

It provides web proxy function for the vnc and ssh services of the other images.

Login

$ ./login/bash
$ ./login/ssh
$ ./login/webssh
$ ./login/vnc

Record and playback

Terminal record/playback

A showterm command is added in the cloud-ubuntu-dev and its derivers, it can be used to record the terminal operations.

$ showterm

VNC record/playback

noVNC can be used to record the VNC desktop operations and the record data can be played back, to record it:

$ VNC_RECORD=1 ./scripts/web-ubuntu.sh

The data is stored in noVNC/recordings/ and the files are named with vnc.record.data.[session number], play back it:

$ VNC_DATA=vnc.record.data.1 ./scripts/vnc-playback.sh

Building

To speedup your building, please focus on such files:

system/base/etc/resolv.conf: customize your own DNS server
system/base/etc/apt/sources.list: customize your own ubuntu mirror site
dockerfiles/Dockerfile.base: customize your own pip index mirror
dockerfiles/Dockerfile.dev: customize your own gem sources
