docker-cross-compiler-novnc's Introduction

docker-cross-compiler-novnc

Docker-based build environment based on dorowu/ubuntu-desktop-lxde-vnc with pre-built and configured toolchains for cross compiling.

Usage

Installation

git clone https://github.com/friendlyarm/docker-ubuntu-lxde-novnc
cd docker-ubuntu-lxde-novnc
docker build --no-cache -t docker-ubuntu-lxde-novnc .

or setup the proxy for Dockerfile building:

vim Dockerfile

Uncomment the following two lines, change the proxy address and rebuild:

# ENV http_proxy http://192.168.1.1:1082
# ENV https_proxy http://192.168.1.1:1082

Note: do not use 127.0.0.1 for the proxy address, use the IP address of the LAN instead

Test Cases

Successfully compiled the following projects:

Environment Variables

`FASTBOOT`

true
Faster container initialization by skipping chown-ing every files and directories under $HOME on container startup. This may be useful when volume is linked on $HOME or its subdirectory, and contains lots of files and directories. Enabling this option might cause files under $HOME inaccessible by container.
false
chown every file under $HOME on container startup.
DEFAULT false

`RESOLUTION`

Set screen resolution in NNNNxNNNN form, like 1366x768.
DEFAULT Follows the size of the browser window when first connected.

`USERNAME`

Name of default user.
DEFAULT root

`PASSWORD`

Password of the user inside the container. This may required if you want to use SSH with password authentication, or normal user rather than root.

`HTTP_PASSWORD`

Password for authentication before loading noVNC screen. USERNAME is used as username. Password may be sent without any protection - use other authentication method when possible if this container is planned to be run as worldwide-public.
