Converting Docker Commands to a Docker Compose File

Have you ever found yourself managing multiple Docker containers using docker run commands and wished for a more organized way to handle them? Using docker run can quickly become cumbersome and hard to maintain, especially if you need to regularly modify container configurations. Fortunately, there's a better solution: docker-compose.yml. In this post, we will walk you through how to convert your docker run commands into an efficient docker-compose.yml format.

The Problem

You may have a set of docker run commands like these:

Each command initializes a different container but managing them individually can be tricky. Wouldn't it be great to have them all in one single configuration file?

The Solution

Below are two versions of the conversion into docker-compose.yml format. You can choose between the exact conversion or a slightly more refined approach, where we use shorter service names and adhere to best practices.

Exact Conversion

This version directly reflects the original commands:

Recommended Conversion

In this version, we adopt better service naming practices and simplify the environment variables:

Important Notes

Container Linking: In the newer versions of Docker, using the --link option is deprecated. When you use docker-compose, all services are automatically placed in a common network, allowing them to communicate with each other through their service names.

Scalability: With docker-compose.yml, you can easily scale services by simply adding more instances or changing configurations without needing to run additional commands.

Conclusion

Transitioning from docker run commands to a docker-compose.yml file not only simplifies the management of multiple containers but also enhances the overall clarity of your infrastructure configuration. Whether you opt for an exact conversion or a more recommended approach, your container management will become much more efficient. Embrace docker-compose today for better orchestration of your Docker containers!
