Docker and Selenium Grid on Google Cloud

I will take you through the very rewarding steps to set-up Selenium Grid using Docker-Compose hosted in Google Cloud.

The Steps we will take.

• Install an Ubuntu instance on Google Cloud
• Open Port 4444 - This port is what our Selenium Grid will be on.
• Install Docker Compose on our new Ubuntu Cloud Instance.
• Install and Run a Selenium Grid via Docker Compose

1. Install an Ubuntu instance on Google Cloud. 

 There are a great cloud services.  I'm choosing Google Cloud because they currently have the best free offering.  $300 (USD) and 60 days.  If you follow my steps, you won't go over 50 cents.

1. Sign up using the free offering:  cloud.google.com

1. Create an Ubuntu 15 instance

1. Give your instance a name and Change Boot Disk

1. Select Ubuntu 15
2. Save your Change
3. Lets open port 4444 by configuring our network
4. Lets create a Rule
5. Now Save the rule for port 4444

1. Install Docker Compose - Click on SSH
2. After the shell opens enter
1. $ sudo su
3. Now install Docker Compose
1. https://docs.docker.com/engine/installation/linux/ubuntulinux/
2. NOTE: Make sure you install for Linux 15 
4. Now the pay off.  Lets get Selenium grid up and running.
1. Create a directory: $ mkdir compose
2. $ cd compose
3. $ nano docker-compose.yml
4. copy and paste
5. hub: image: selenium/hub ports: - "4444:4444"chrome: image: selenium/node-chrome links: - hubfirefox: image: selenium/node-firefox links: - hub
6. Save
7. Run: $ docker-compose up
8. You can see the selenium-grid at <instance ip>
1. http://104.197.200.6:4444/grid/console

1. Docker scales easily making this perfect Testing.
2. Run: $ docker-compose scale chrome=7
3. What we get is 7 additional agents!

Now - let's run a Selenium Test using our new toy.
