Install Digital Lab with Docker

This section describes how to install Digital Lab on a Linux platform using Docker. With Docker, you develop, ship, and run applications via a container. This section is relevant only for UFT Digital Lab.

Install Docker

Docker uses a standard container format that lets developers prepare applications inside containers. System administrators and other teams, such as Quality Assurance engineers, run the container to deploy the application. For details, see the Docker documentation.

Follow the steps below to install Docker:

  1. Install Docker on the target machine, along with its dependencies. Currently, only the 64-bit version is supported. For installation details, see the Docker Installation guide.
  2. Set up the target machine environment as required.

Obtain the Digital Lab server image

Obtain the latest Digital Lab Docker image from the Docker hub.

Type the following in your Linux environment:

Copy code 
docker pull mobilelifecycle/uft-digitallab:23.4

 

The image contains the Dockerfile of the Digital Lab server that connects to a remote Postgres database. (The database installation is not included in the package.)

Note that SSL is not supported when installing Digital Lab with a Docker image.

Run PostgreSQL

The PostgreSQL database used by Digital Lab is not included in the Digital Lab server image. Make sure that you have the PostgreSQL database up and running on a machine that can be accessed by the server.

We recommend PostgreSQL version 11. If you don't have PostgreSQL, obtain it from the Docker hub by typing docker pull postgres:11.

To run the PostgreSQL container in the background:

Enter the following command when using the default PostgreSQL port (5432):

Copy code 
docker run --name postgres -p 5432:5432 -e POSTGRES_PASSWORD=[postgres_password] -d postgres:[PostgreSQL version number]

If you need to use a custom port, run the following:

Copy code 
docker run --name postgres -p [custom_port]:5432 -e POSTGRES_PASSWORD=[postgres_password] -d postgres:[PostgreSQL version number]

Make sure to use this custom port for POSTGRES_PORT= in the command for running the Digital Lab  server in Start a container and launch the Digital Lab server.

Note: PostgreSQL adds a default user postgres.

Start a container and launch the Digital Lab server

After you have the PostgreSQL database up and running, start the Digital Lab server container.

To start the Digital Lab container:

  1. Check that the default port, 8080, is available and not being used by another process.

  2. Run the following command to run the Digital Lab server in the background in detached mode. The default PostgreSQL user is postgres:

    Copy code 
    docker run -d --name dl -p 8080:8080 -e POSTGRES_HOST=[postgres_ip] -e POSTGRES_PORT=5432 -e POSTGRES_USER=[postgres_user] -e POSTGRES_PASSWORD=[postgres_password] -e FQDN=[host_ip] mobilelifecycle/uft-digitallab

    If you need to use a custom port, specify the custom port as follows:

    Copy code 
    docker run -d --name uftm -p [custom_port]:8080 -e POSTGRES_HOST=[postgres_ip] -e POSTGRES_PORT=5432 -e POSTGRES_USER=[postgres_user] -e POSTGRES_PASSWORD=[postgres_password] -e FQDN=127.0.0.1 mobilelifecycle/uft-digitallab

    Note:

    • When using a custom port, set FQDN to 127.0.0.1

    • If you specify non-default ports, you also need to modify the ports on the connector and tools.

Starting with UFT Mobile(Digital Lab) 3.20, applications are no longer stored in the Postgres DB, but on the physical disk. This means you need to use a volume to maintain the persistence of the applications after the container is exited:

Copy code 
docker volume create dl_data
docker run -d --name dl [options] -v dl_data:/opt/UFTDigitalLab/mcStorage mobilelifecycle/uft-digitallab

Begin your Digital Lab test

To use Digital Lab for testing your mobile app:

  1. Open the Digital Lab home page http://<host>:<port> and log in with the default credentials:
    Email: admin@default.com
    Password: password
    It may take a minute for the server to start up, and for the page to open.
  2. Install the appropriate Digital Lab connector on the machine/s to which you are connecting devices with a USB cable. You can connect multiple devices to the Docker host machine. The connector can be installed on the same machine on which Docker is installed. For details, see Install the connector on a Windows machine, Install the connector on a Linux machine or Install the connector on a Mac machine.

  3. Prepare your Digital Lab test with the relevant testing tool, such as UFT, Sprinter, or TruClient.

Tips and guidelines

The following table includes a list of useful Docker commands:

Command Action
docker ps Lists the containers that are running
docker stop dl Stops the Digital Lab service
docker start dl Starts the Digital Lab service
docker images Lists the images
docker inspect dl|grep '"Source": "/var/lib/docker/volumes' Check the logs of the running Digital Lab container.

The output has the following form:

"Source": "/var/lib/docker/volumes/07ec0041ecf5f86934d2957648a24248fefeffdbb0da3a5b353d1d1fe480b656/_data"

Append server/log to the above path shown in the output. This folder contains the log files.
