Docker s a tool used to streamline work with multiple containers. Thanks to Docker Compose the user is able to run an environment with multiple containers with a single command. To use Docker Compose you will need to create a file with the extension .yml. The default filename that Docker Compose expects is d example file might look like this. version services web build . ports " " volumes . code linksimage redis The above configuration contains a declaration of running two containers. One of them is some local application whose source code is in the code. The application is available externally on port.
Please remember that the application must haveThe second container however uses a ready made image in this case a Redis image. Once you have such a file all you need Phone Number List to do is run the command docker compose up. This will launch the containers. Of course Docker Compose offers much more than the example shown. Thanks to this tool you can for example pass environment variables to containers define and configure a network for communication between containers or force them to run in a specific order.
For a full list of Docker Compose capabilities see the Docker documentation. What is Docker volume used for It is worth noting that in the previous example the first application uses Docker volume. By using volumes we create a link between the specified location in the container and the specified location on the local machine. This procedure allows you to constantly observe how changes in the source code affect the operation of the application without the need to rebuild the image after each change.
