Docker and Kubernetes are leading containerization technologies and key tools in modern software development. Containerization is a development method in which code, necessary frameworks, and libraries run in an isolated container. This independent environment ensures the reliability and portability of applications, allowing them to function independently of the operating system. The benefits of containerization include fault tolerance: a problem in one part of the application does not affect the rest, significantly improving stability and performance. Using containers also simplifies application deployment and scaling, making them ideal for cloud-native solutions and microservices architectures.
Docker and Kubernetes are important tools for working with containers, but their purposes differ. Docker is primarily designed for developing, building, and running containers, providing developers with a convenient means of packaging applications and their dependencies. Kubernetes, on the other hand, focuses on managing containers in production, providing capabilities for automating the deployment, scaling, and management of containerized applications. Thus, Docker and Kubernetes complement each other, enabling the creation of efficient and scalable solutions for application development and operations.
Docker has its own equivalent to Kubernetes: Docker Swarm. Comparing Kubernetes to Docker Swarm is apt, and the number of stars on GitHub shows that Kubernetes is significantly ahead of its competitor. Therefore, using Kubernetes in combination with Docker is an optimal solution, as both products complement each other perfectly, rather than being direct competitors.

Working with source code requires caution to avoid leaking confidential information. However, there are other aspects that require attention, especially when it comes to Docker images. The recent Codecov incident vividly illustrates this risk: one of the Docker images contained credentials for a Git account, which hackers used to access a private repository, leading to serious consequences. It's important to remember that the security of Docker images is no less critical. It's recommended to thoroughly inspect the contents of images and ensure they don't contain personal data or confidential information to prevent similar incidents in the future. Image security presents several significant challenges. First, they contain source code, and due to the nature of their structure, this can go undetected during inspections. Second, images can hide authorization data and API keys, as evidenced by incidents like the Codecov incident. Third, images are composed of layers, which creates additional risks: one layer may contain information from previous layers, increasing the likelihood of data leakage. It's important to note that image checks are often not as thorough as source code checks, making them vulnerable to attack. Ensuring image security requires careful monitoring and regular auditing to minimize risks.
The authors of this article conducted a study on the Docker Hub platform to determine how much sensitive information is contained in container images and source code. The results showed that source code in most cases contains more vulnerabilities. However, container images were not without flaws either: 7% of them were found to have various flaws. These data highlight the importance of carefully analyzing both source code and images when working with Docker.
