React Programmer recruitment questions – Git Programmer – recruitment questions – TypeScript Programmer – recruitment question databases You can also treat questions from this series as training and checking your skills before a job interview. What is Docker and what is it for To start working with Docker it is worth knowing what it is. Docker is a tool for running containers.
Thanks to containers you can easily run applications without physically installing them on the machine you are using. For example if you want to run a database you do not need to install it Phone Number List locally. All you need to do is launch a container based on the selected database image and define how to communicate with this container. In the same way you can containerize the application you are developing. An important aspect of containerization using Docker is that the containers do not know anything about each other until the user explicitly declares otherwise.
That is if you have a container with a database and a container with the application you are developing you must also define how these two containers should communicate with each other. What is the difference between an image and a container This question includes understanding what an image and what a container are what are the differences between them and what is the relationship between them. An image can be called a "snapshot" of the application you need to run. To use an analogy from object oriented programming an image can be likened to a class.
