Go Grid Router (aka Ggr) is a lightweight active load balancer used to create scalable and highly-available Selenium clusters.

• Selenium testing: a new hope (part I)
• Selenium testing: a new hope (part II)

To use Go Grid Router do the following:

1. Install Docker to host
2. Create configuration directory:

$ mkdir -p /etc/grid-router/quota

3. Create users.htpasswd file:

$ htpasswd -bc /etc/grid-router/users.htpasswd test test-password

4. Start Selenium standalone server on port 4445:

$ java -jar selenium-server-standalone.jar -port 4445

You can also start Selenoid instead.

5. Create quota file (use correct browser name and version):

$ cat /etc/grid-router/quota/test.xml
<qa:browsers xmlns:qa="urn:config.gridrouter.qatools.ru">
<browser name="firefox" defaultVersion="59.0">
    <version number="59.0">
        <region name="1">
            <host name="localhost" port="4445" count="1"/>
        </region>
    </version>
</browser>
</qa:browsers>

Note: file name should correspond to username you added to htpasswd file. For user test we added on previous steps you should create test.xml.

6. Start Ggr container:

# docker run -d --name ggr -v /etc/grid-router/:/etc/grid-router:ro --net host aerokube/ggr:latest-release

7. Access Ggr on port 4444 in the same way you do for Selenium Hub but using the following url:

http://test:test-password@localhost:4444/wd/hub
