To configure the necessary infrastructure in order to carry out the complete cycle or only a part of it, it will be done by using Docker containers. We will explore two methods for configuring such containers, using Docker Compose or Kubernetes.

Docker-compose​

Docker-compose is a tool that allows you to define and run multi-container applications with Docker. It uses a YAML file to configure the services, networks and volumes required for each application container.

Advantages of Docker-compose​

  1. Simplicity: Docker-compose simplifies the management of multi-container applications by defining all services in a single YAML file.
  2. Isolated development environment: Allows the creation of isolated development environments with all the necessary dependencies to run an application.
  3. Rapid deployment: Facilitates rapid deployment of applications in any Docker-compatible environment.
  4. Flexibility: It is easy to configure and allows the customization of each container according to the needs of the project.

Disadvantages of Docker-compose​

  1. **It is designed to deploy applications on a single host, which limits its capacity for more complex implementations.
  2. No automatic scalability: No built-in tools to automatically scale containers in response to demand.
  3. Manual management: Requires manual management for advanced operations, such as load balancing or high availability.
  4. Docker-dependent: Its functionality is tied to Docker, which may limit the options in environments where Docker is not the best choice.

Kubernetes (K8s)​

Kubernetes is an open source platform designed to automate the deployment, scaling and management of containerized applications. Provides a highly scalable and flexible container orchestration environment.

Advantages of Kubernetes​

  1. Automatic scalability: Kubernetes offers automatic scalability, which allows you to increase or decrease the number of replicas of a container depending on the workload.
  2. **Provides features to ensure high availability of applications, including workload distribution and fault tolerance.
  3. Full orchestration: Provides full container orchestration, including network management, storage, monitoring and load balancing.
  4. Multi-cloud and multi-environment: It supports multi-cloud and multi-environment environments, enabling application portability between different cloud providers and on-premises environments.

Disadvantages of Kubernetes​

  1. Learning curve: Requires time and effort to become familiar with Kubernetes concepts and architecture.
  2. Complexity: Can be complex to configure and maintain, especially for simpler applications that do not require all the features of Kubernetes.
  3. Infrastructure required: Requires adequate infrastructure for implementation, including servers and network resources.
  4. **Can consume a significant amount of hardware resources, especially in large-scale deployments.

Comparison between Docker-compose and Kubernetes​

Scalability​

  • **Docker-compose is designed to deploy applications on a single host, which limits its ability to automatically scale containers.
  • **Kubernetes offers automatic scalability, allowing to increase or decrease the number of replicas of a container according to the workload, which makes it ideal for highly scalable applications.

Complexity and Learning Curve​

  • Docker-compose: It is easy to learn and use, as it simplifies the management of multi-container applications with a YAML file.
  • **Kubernetes has a steeper learning curve due to its architecture and the number of concepts involved, which requires more time and effort to fully master.

Orchestration and Container Management​

  • Docker-compose: Provides basic container and service management, suitable for simple or development applications.
  • **Kubernetes offers full container orchestration, including network management, storage, monitoring and load balancing, making it more suitable for complex and production applications.

Portability and Multi-environment​

  • Docker-compose: It is more portable and can run in any Docker-compatible environment, but is limited to a single host.
  • **Kubernetes supports multi-cloud and multi-environment environments, allowing portability of applications between different cloud providers and on-premises environments, providing greater flexibility.

Use of Resources​

  • Docker-compose: It is lighter in terms of resources, as it is designed to deploy applications on a single host.
  • **Kubernetes can consume a significant amount of hardware resources, especially in large-scale deployments, due to its distributed architecture and advanced container management features.

In summary, Docker-compose is better suited for development and test environments or simple applications, while Kubernetes is better suited for production environments and complex applications that require scalability, high availability and advanced container management features. The choice between the two depends on the specific requirements of the project and the desired level of complexity of the container infrastructure.
