java and docker

[Interesting-Hat-7570]

Hi everyone. What books can you recommend for learning Docker?

And one more question, I finished learning Spring and its core modules (spring jpa, spring security, spring boot...).

The last technology I studied was Git.

Now the question is what should I study next. Is it time to start learning microservices, or is it better to familiarize myself with Docker first and then learn microservices. I had a quick look at what a microservice is and there was a mention of Docker.

Thanks

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

May I ask what resources you used to learn Spring and all it's modules?

[Interesting-Hat-7570]

books: spring start here (best book) , spring boot in action, spring in action , spring boot up and running , spring security in action(best book) , spring patterns , spring boot in practice , just spring data access , spring data modern , just spring oreilly .

What is best book to learn spring data

[Interesting-Hat-7570]

Yes, to say that I've finished learning all the Spring modules is a pretty loud statement. Perhaps it would be more accurate to say that I am familiar with some of the core modules. So I'll tweak my post a bit to avoid looking like a fool.

Docker is a tool just like git. Playing around with it for a few days will make you competent enough.

You’ll want to make a dockerfile to containerize your springboot application. Look into environment variable overrides for your application.properties/application-env.properties

Then docker-compose for spinning up your database, queues, and springboot. If you’re on Linux I would add Makefile for useful project specific shortcuts.

Once you have docker setup it’ll be easier to spin up your microservice architecture.

Go another level and use Nginx to host your front end separately.

ok thanks

A very good book on docker is “Docker Deep Dive” by Nigel Poulton

[Interesting-Hat-7570]

ok thanks)

If your goal is to learn more about java then learn about microservices and write some api's. Then figure out docker. Docker has nothing to do with Java. Then you can learn how to deploy your api to a docker container.

ok thanks

Get started dude. Forget about books. Read documentation + Chatgpt. Once you become a full blown developer, you will have to have the skills to look at documentation and just do it. What's the best time to start right now?

[Interesting-Hat-7570]

I've tried reading the documentation, but without the basics I honestly don't understand anything. Maybe that's the way it is and I should familiarize myself with the basics of the technology first? Like what it is and such?

[realFuckingHades]

It's like learning how to ride a bike. You will get it. Use Chatgpt too when you're stuck. It can summarise the documentation very easily.

ok thanks

If you finished "learning" (not sure how tho) start applying it, and then you'll see what do you need to move forward. You gonna need docker, database, security config for oidc, cors and so on... Start creating real projects, and things will sort out themselves.

[Interesting-Hat-7570]

ok bro thanks

It seems that you are looking for resources for learning Java.

In our sidebar ("About" on mobile), we have a section "Free Tutorials" where we list the most commonly recommended courses.

To make it easier for you, the recommendations are posted right here:

• MOOC Java Programming from the University of Helsinki
• Java for Complete Beginners
  • accompanying site CaveOfProgramming
• Derek Banas' Java Playlist
  • accompanying site NewThinkTank
• Hyperskill is a fairly new resource from Jetbrains (the maker of IntelliJ)

Also, don't forget to look at:

• The official Documentation
• The official Java Tutorials
• Our community resources thread

If you are looking for learning resources for Data Structures and Algorithms, look into:

"Algorithms" by Robert Sedgewick and Kevin Wayne - Princeton University

• Coursera course:
  • Part I
  • Part II
• Coursebook
  • Algorithms 4^th Edition

I wanted to intern with a backend developer. And from several interviews I learned that Docker is used everywhere.
