The markup language used to write Docker configuration files is:

Which of the following is not a container-based alternative to Docker?

Верно!

Не верно!

Kubernetes is an orchestration tool that manages Docker deployments, but it is not a Docker alternative. LXD, rkt and the Windows Server Containers are container implementation technologies that compete with Docker.

What happens if you attempt to perform a Docker build based on an image that has not been previously referenced on your machine?

Не верно!

Docker will look at the local image repository when a container image is referenced in a Dockerfile. If one is not found on the host, Docker will search for an image with the same name and version number on Docker Hub.

Information on how to build a Docker image is written in a file named:

The Docker naming convention recommends that users save information on how to build a container image in a file named Dockerfile.

Which of the following statements is most correct?

Не верно!

When a process based on a Docker image is started, it is referred to as a container. In contrast with containers, Docker images are built. And it is the container, which is based on the image, that is run.

The Docker logo is:

Не верно!

This may seem like a silly question, but when you find out that Kubernetes refers to a group of Docker containers as a “pod,” some of the cloud-native naming patterns start to make sense.

A butler is the Jenkins logo. The sailboat goes with Jakarta EE. And the Octocat is the GitHub logo.

Верно!

Which programming language was used to write Docker?

Не верно!

Go, also known as Golang, was the language used to code the implementation of the Docker container.

Go is a compiled programming language that was first released in 2009. As you may have guessed by the two letters in the name, it was created by a group of developers at Google.

Верно!

A Docker container is often described as an improvement over what other technology?

Не верно!

Docker containers are often compared to VMs, as both provide the ability to deploy and run multiple, independent applications on the same physical machine.

Docker containers are less resource intensive, as they provide process-level virtualization as opposed to full OS virtualization provided by a VM, which is one of the reasons the industry has shifted toward containers.

The history of application containerization is intimately tied to which OS?

Не верно!

Linux added two features to its kernel, namely control groups and namespaces, that made it possible to run software in isolated containers. These two changes made the container revolution possible.

At the OS level, the goal of independent application execution and failure isolation is achieved through the use of:

Верно!

Не верно!

Namespaces make the isolation of the process that runs a Docker container possible.

Control groups are what make it possible to limit the amount of CPU time and memory allocated to a given container.

Security groups are typically associated with AWS configurations, and Kubernetes is a container orchestration tool.
