Setting up mabl Link with Docker removes the need of installing Java and setting up the Java-based Link Agent distribution on the host machine. Instead, you can run the Link Agent inside a Docker container. You can get the Link Agent Docker image from the Dockerhub.
To run the Link Agent inside a Docker container, use the following command.
$ docker run mablhq/link-agent --api-key <your-api-key> --name <agent-name>
Alternatively you can run the container as a background daemon process in the following way:
$ docker run -d --name mabl-link-agent mablhq/link-agent \ --api-key <your-api-key> --name <agent-name>
Once you run the Docker container, go to Using mabl Link - Step 4 to proceed with the rest of the Link service setup.
By default the Docker container will resolve
localhost to the guest (i.e. the container itself) rather than the host (i.e. the machine running Docker). If your test needs to access services running on the docker host, such as
localhost URLs, you will need to take additional steps that are specific to your host operating system. Find the instructions below for your OS.
If Docker is running on a Linux system, add the following argument after
--net="host". For example:
$ docker run --net="host" mablhq/link-agent --api-key <your-api-key> --name <agent-name>
The next step involves creating an alias for
localhost because most browsers will not allow proxying requests to
localhost. Edit your
/etc/hosts file, and look for a line like the following:
Choose an alias for
localhost, such as
link-host (or choose your own name), and add it to the end of the line. The new line should look like this:
127.0.0.1 localhost link-host
Finally, update your environment URLs in mabl to use
link-host instead of
localhost. For example, if your URL is
http://localhost:3000 the new URL should be
To test against
localhost on OSX, the only change that needs to occur is to update the URL in your mabl environment. Instead of
host.docker.internal. For example, if your URL was
