Docker Architecture Job Interview Questions

Docker architecture is built around a client-server model that facilitates the creation, deployment, and management of containers. At the heart of Docker’s architecture is the Docker Engine, which consists of three key components: the Docker Daemon, the Docker CLI (Command Line Interface), and the Docker Registry. The Docker Daemon is responsible for managing containers, images, networks, and volumes on the host system, while the Docker CLI provides the interface for users to interact with the Docker Daemon through commands. The Docker Registry stores Docker images, with Docker Hub being the default public registry. Docker uses containers to run applications in isolated environments, while images act as the blueprints for these containers. This architecture allows for consistent, portable, and efficient management of applications across different environments, from development to production.

11. What are the main components of Docker?

Docker Client: The command-line interface (CLI) used to send commands to Docker.
Docker Daemon: A background service (dockerd) that manages containers and images.
Docker Registry: Stores Docker images. Examples include Docker Hub and private registries.

Docker Networking Job Interview Questions

Docker networking enables communication between containers, as well as between containers and the outside world. It provides various network drivers, including bridge (default for standalone containers), host (shares the host’s network stack), overlay (for multi-host communication in Swarm mode), and macvlan (assigns MAC addresses to containers). These drivers allow you to customize how containers interact with each other and external systems. Docker also supports creating custom networks to isolate containers or connect them securely. Understanding Docker networking is crucial for managing containerized applications effectively in both standalone and distributed environments.

41. What are Docker networks?

Docker networks allow containers to communicate with each other and with external systems. They manage how containers connect and isolate their traffic when needed.

42. What are the types of Docker networks?

Bridge Network: Default network for standalone containers on a single host.

None Network: Completely disables networking for a container.

43. What is a bridge network, and when should you use it?

A bridge network is the default network for standalone containers on a single host. It’s best for containers that need to communicate with each other on the same Docker host.

44. How does a host network work in Docker?

The container shares the host’s network namespace. This is useful when the container needs high-performance network access or port sharing.

45. What is the purpose of an overlay network?

An overlay network allows communication between containers on different Docker hosts, typically in a Docker Swarm or Kubernetes cluster.

46. What is a Macvlan network?

A Macvlan network assigns a unique MAC address to containers, allowing them to appear as separate physical devices on the network.

Docker Storage Job Interview Questions

Docker storage provides mechanisms to manage and persist data generated by containers. It offers two primary storage options: volumes and bind mounts. Volumes are managed by Docker and stored outside the container’s filesystem, making them ideal for data persistence and sharing across containers. Bind mounts map a directory or file from the host system into the container, providing flexibility for local development. Docker also supports tmpfs mounts for ephemeral data stored in memory. Effective use of Docker storage ensures data durability, portability, and efficient management of containerized applications, especially in production environments.

Volumes: Managed by Docker, portable, and better suited for production.
Bind Mounts: Use specific host directories and require manual setup.

57. How do you create a Docker volume?

Use the command: docker volume create <volume-name>

58. How do you attach a volume to a container?

Use the -v option with docker run: docker run -v <volume-name>:/path/in/container <image-name>

Docker security focuses on securing the containerized applications and the host environment by implementing best practices and utilizing various security features. Key aspects of Docker security include image security, ensuring that images are built from trusted sources and regularly scanned for vulnerabilities. Container isolation is another crucial element, where Docker uses namespaces and cgroups to separate containers and limit their access to host resources. Docker Content Trust (DCT) ensures image authenticity by verifying digital signatures. Role-Based Access Control (RBAC) and secrets management help restrict access and securely store sensitive data. Additionally, using Docker security scanning tools, managing network policies, and applying the principle of least privilege are all critical for protecting containerized environments from potential security risks.
