But real-world projects are not always as straightforward and simple as they appear. During development, we constantly require multiple dependencies or services to function, such as a database, cache, message broker, and so on. Rasel realized we needed something to solve this problem. Rasel was looking for a solution that was capable of handling multiple container bootstrapping. And guess what? Rasel discovered that Docker Compose is the solution. That’s why, Rasel decided to learn Docker Compose and Docker Swarm in detail. ...

Rasel wanted to go hands-on with Docker after understanding these concepts. So, as planned, Rasel begins with the Docker architecture and basic commands that needs for his day-to-day development. And gradually move to the advanced concepts of Docker. ...

Now he thought it was time to start learning DevOps tools. But where should he start? There are numerous tools that are commonly used in DevOps practice. Then he made the decision to start with Docker. Because as a software engineer he faced numerous challenges when installing, running, and building software and its dependencies. And the well-known issue “It works on my machine” always arises. As far as he knew, Docker, or container technology, solved this type of problem. That is why he decided to learn containerization first. ...
