The Docker online test evaluates a candidate’s ability to work with the platform virtualization tool Docker, including the knowledge of how to configure containers and images, run services within those containers, and manage the lifecycle of those containers.
It’s an ideal test for pre-employment screening of candidates applying for any developer role. A good candidate for any job requiring the use of virtualization will be able to display competency with using Docker, one of the most popular containerization and virtualization platforms. This Docker test can be used to screen large groups of candidates to select only those with the required Docker knowledge to bring in for an interview.

# of candidates
Docker is one of the most popular virtualization platforms as it allows for isolated software packages called containers to be bundled in a customizable and configurable manner.
Command Line Arguments
Command Line Arguments
Many programs can be passed parameters via a command line interface and developers will often use common commands, arguments, and options that can modify the operation of their programs and tools.
Compose allows developers to configure and run multiple containers in a single Docker application.
Public questions (free account) are common interview questions. They are great for practicing, or if you want to filter candidates using the classic problems.
The automation team is testing their background Docker web server containers. They need to cleanly remove the existing containers without leaving any artifacts behind, then start new containers.
Complete the following docker commands to achieve these objectives:
# Gracefully end all processes in the containers
host> docker-compose stop
# Remove the containers and their anonymous volumes
host> docker-compose ____ -v
# Start containers in background
host> docker-compose up ____ apache php mysql
Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.
We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.
Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.
Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
