In a Dockerfile, you specify the build command and arguments as well as any other stuff you think is relevant. This can be a pretty useful resource for new contributors and new users. A typical example is the docker build command.
In this case, I wanted to build a Dockerfile to serve a custom image. For instance, I might want to build Dockerfiles for a project I’m working on, or create Dockerfiles for a new project. In general though, a Dockerfile is a really handy thing to have at hand.
I was recently trying to teach a class and I was asked if I knew a bit about Dockerfile. There were a few interesting questions, but I was able to answer most of them.
Dockerfile is a file that a container will use to build images. This is why images are named after the files that make up the container. Say, for instance, an image of a web application: A container would make a new image based on the web application’s web.config.
Dockerfiles are used to define how a container should be built, so a user could create an image that was not going to build with only web.config or that only used the web.config. It also works to customize the way a container can be built, but we’re not going to cover that in this article.
docker build does a number of things like setting up the Docker Compose file, and configuring the build to use a specific container image. But what makes it special is that the image name it specifies is the name of the file that is going to be used by the container (like, for example, web.config). This allows you to tell Docker how to use your development image.
For example, you might want a Docker container to use a specific web image that has a web.config file. In this case, you don’t need to specify that in your Dockerfile. Docker Compose can be used to do this, but it’s recommended that you do that after each container builds.
The difference between Docker Compose and Docker Container is that Docker Compose will run containers, but it will not run a container. By default, docker container can run containers for free and run from the Docker Compose container. But containers are NOT run as a command line command, they are run as an on-disk command file and written to disk.
The two main benefits of using Docker Container is that you can create containers for specific services or applications, or you can run multiple containers for different services or applications. To run multiple identical containers, you can run the same command file in the Docker Compose container. To run multiple identical images, you can use the same command file in the Docker Compose container.
So how do you create a Docker Compose command file? It’s a simple thing, you go to and download both the default and the recommended docker-compose-config file. You run the following command to create a new file.
