Confused between Dockerfile and docker-compose because they look and sound similar? But they are not. Read this to clear your doubts. A Dockerfile is a simple text file that contains the commands a user could call to assemble an image whereas Docker Compose is a tool for defining and running multi-container Docker applications. Docker Compose define the services that make up your app in docker-compose.

I've seen many people get confused between a Dockerfile and a Compose file. This is primarily because both are used to modify a Docker image in a way, though it's not technically correct.

Let me go in a bit of detail so that you properly understand the difference between Docker Compose and Dockerfile.
Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub.
Welcome to this on Docker Tutorial for Beginners. In this video provides an Introduction on C++ development with Docker containers. So we will see How to ship C++ Programs in Docker.
“Docker: Understanding Docker Architecture and Components”, The First thing we are going to do is to run the “docker run hello-world” command. This command tries to find the “hello-world” image locally and if not found, it then downloads an image from the docker hub and runs the container out of this image.
This entry-level guide will tell you why and how to Dockerize your WordPress projects.
Manage Data in Docker -Understanding “Docker Volumes” and “Bind Mounts”. Volumes are stored in a part of the host filesystem which is managed by Docker (/var/lib/docker/volumes/ on Linux). Non-Docker processes should not modify this part of the filesystem. Volumes are the best way to persist data in Docker.
