Let's discover: docker init command

#docker #video #beginners

Welcome in this new (serie of?) article titled: "Let's discover".

This time, no sketchnotes, but we will discover a new tool, a new technology or this time, a new command that I wait for a loooonnggg time: docker init command.

Docker init

In short: docker init allows you to dockerize your application. That's it! :-)

When you execute docker init command in your project, in your repository for example, it generates for you:

a Dockerfile
a .dockerignore
and a ~~docker-compose.yaml~~ compose.yaml file

So after executing docker init command you just have to build and run your container or run it through docker compose and test your application :-).

Test it!

Stop the blahblah, let's discover and test this new docker init command, in video! :-)

As you can see, the docker init command is in Beta and you need to update Docker Desktop to version 4.18.
~~At the moment it only supports the Go language and the teams are working to support Python, Rust, Node.js, Java and even .Net languages.~~

Edit: At the moments it supports Go, Python, Rust & Node.js and the teams are working to support Java and even .Net languages.
If you want a support for a specific language or a framework, you can ask to Docker.

Conclusion

As I said before, I have been waiting for this command for a long time.

I love to fine-tune my DockerFile in order to have small Docker images but I like when things are easy and frictionless and I know it's not easy to create a simple DockerFile when you start (and even when you know Docker technology ^^) so I'm happy with this new feature and I hope it can help a lot of people to start their Docker and Containers journey! :-)

So I'm telling everyone at work that the compose spec says it should be compose.yaml and no longer docker-compose.yaml, and Docker adds a new command that creates a… docker-compose.yaml 😭
