Simply put, Docker Compose makes complicated tasks easier by eliminating conflicts and organizational issues. Starting, halting, and creating intra-container linkages and volumes are all made easier with this tool. Say Hello to Docker Composeĭocker Compose is a container management tool that allows you to configure and orchestrate all your Docker containers into a single YAML file. Remember, if you choose to delete a container, you will also lose the Container Layer. Every container you create has a different read/write Container Layer, and any changes made in the Docker container are automatically reflected upon the Container Layer. The newly created layer contains the application and its dependencies. When you create a Docker container, a new layer known as Container Layer is created.
A single container is built using the Docker image through the run command. To check the number of images running in your system, use the command:ĭocker images and containers work hand-in-hand to unleash the potential of Docker. We use a Docker image to create one or more Docker containers as per our needs. Once you create Docker images, you cannot modify them, though it allows deletion. You can also take a look at our comprehensive guide that explains the fundamental Docker concepts.ĭocker images are a collection of read-only files. If you think you are familiar with these concepts, feel free to skip and move forward with the next section. In this section, we are going to define a few concepts that are essential for beginners. Understanding how Docker works can be tricky if you have no experience working with it. Docker Containers and ImagesĪs you dive in to further understand Docker, it is essential to brush up with the basics. Unbeatable functionalities such as orchestrating, defining, and running multi-container applications together make Docker a favorite pick for developers. Containerization technology does not just enable rapid application development and efficiency, but also saves time and strenuous efforts. Since its inception, the Docker team has continuously strived to make automated deployment seamless. Dockerisation has redefined the deployment and automation process in the software industry.
