#howtox-server

An node app that converts incoming HTTP requests to Docker command, run those command through docker run, and returns a webpage with a cloud-IDE and a cloud-terminal.

NOT secure due to docker needs ROOT access. Read more from Docker

Running containers (and applications) with Docker implies running the Docker daemon. This daemon currently requires root privileges, and you should therefore be aware of some important details.

• Create a DigitalOcean droplet with ref code
• Choose 'Docker on Ubuntu' under 'Select Image'->'Applications'. see
• Set up the droplet as usual
• Clone down this repo
• Set up this repo

• Assuming your droplet can be accessed by azat.howtox.com
• Assuming the docker image howtox/express already exist on your droplet
• The user clicks azat.howtox.com:3000/launch/howtox/express
• Express.js run this command

docker run -d -p 63814:3131 -p 63815:3132 -p 63816:3133 howtox/azat-express /usr/local/bin/supervisord

• Express.js then redirect the user to azat.howtox.com:3000/box/63814, and present the user with the following HTML

#first iframe is the editor
<iframe src="//azat.howtox.com:63814">
#second iframe is the terminal
<iframe src="//azat.howtox.com:63815">

• Make sure you picked the correct image 'Docker on Ubuntu'

apt-get update
apt-get upgrade -y
apt-get install nodejs -y
apt-get install npm -y
ln -s `which nodejs` /usr/local/bin/node
cd /home
git clone https://github.com/howtox/howtox-server
cd /home/howtox-server && npm install
# run the app by node app.js
#
#add env
#
vi ~/.bashrc
#optional
#export p_analytics_secret='secret_write_key_from_segment.io'
export EDITOR=vi

• Basically, you want to set up node.js and some environment variables. The other way to set up node/npm is using nvm.
• Finally, edit app.js to change the following global variables

global.APP_CONFIG = {
  domain: 'azat.howtox.com',
  containerLifespan: 600, //in seconds
  whitelistedImages: ["howtox/yc_base", "howtox/azat-express", "howtox/express"]
};

docker pull howtox/yc_base

TBD

• Get the url for the repo of interest. In this case, https://github.com/howtox/express.
• In the droplet

cd /home/howtox-server/controllers
node docker_build_image_cmd.js howtox/express

• Wait for a very long time...
• Verify the image has been built by

docker images | grep 'howtox/express'

• Update the app.js to add that image to the whitelist

global.APP_CONFIG = {
  domain: 'azat.howtox.com',
  containerLifespan: 60, //in seconds
  whitelistedImages: ["howtox/yc_base", "howtox/azat-express", "howtox/express"]
};

• Start the node app by node app.js and you should be able to visit the new image at: http://azat.howtox.com:3000/launch/howtox/express

npm install howtox-tty.js

• might need xcode command line tool
