Creating Docker Images With Spring Boot

[@infitium7246]

Previously, I had to write scipts for each application then start the pipeline bla bla... you get the point. I am thankful to you guys. Great Job!!!

[@ViktorGamov]

What kind of sorcerery is it😜? Great work, guys!

[@shivamrajput7916]

This is so much awesome we can test our application in test and production similiar to our laptop so we have atleast same of consistency during dev Great works guys 😊👍🏻

[@jef-]

Had no idea about dev tools. That's awesome. Thanks for the video! I'd be interested to see the differences on creating a Dockerfile vs using this new Spring Docker Build.

i guess im asking the wrong place but does any of you know of a tool to get back into an instagram account..? I was dumb forgot my password. I would appreciate any assistance you can offer me!

@Jerry Sam instablaster ;)

[@jerrysam2001]

@King Atlas i really appreciate your reply. I got to the site thru google and Im waiting for the hacking stuff atm. Seems to take a while so I will get back to you later with my results.

[@jerrysam2001]

@King Atlas it worked and I actually got access to my account again. I am so happy:D Thank you so much, you saved my ass !

[@kingatlas2891]

@Jerry Sam Happy to help :)

How to create an image when we have some extra dependencies like JPA, Messaging etc... Is there any utility to create something like docker-compose using this plugin.

[@jawin5915]

What could be the default configuration of docker and how can we customize that

[@jawin5915]

I think docker should be running on the devlopers machine to get this feature. Correct me if I'm wrong

[@michaelrusso558]

@@jawin5915 Yes, Docker is a required dependency See: * docs.spring.io/spring-boot/docs/2.3.0.RELEASE/maven-plugin/reference/html/#build-image-docker-daemon * docs.spring.io/spring-boot/docs/2.3.0.RELEASE/gradle-plugin/reference/html/#build-image-docker-daemon

Hi, I have a question is Why the docker image so big ? I just build a small app with some dependencies (spring security, cloud, jpa, liquibase, log4j2, ..), and the docker image is 300MB @@! beside that, jar file just 60MB Did I make something wrong ? Do we have any way to build a docker image with a smaller size ?

[@huckthatdish]

just speculation as I havent played around with 2.3.0, but if it works like building an image from a dockerfile, I think by default the image contains every file in the working directory. Try using a docker.ignore file to prevent adding cruft to your image.

[@MrVitalirapalis]

Use alpine as base image

[@51aw0m1r]

mate, it needs jre to run, checkout docker image layers.

[@tuoan5533]

ah, I got it, docker image includes a lot of things to run independently, so that why its size is big. Thank you all :D However, when "docker images", the CREATED column show my image is created "40 years ago", it make me quite confuse

[@huckthatdish]

Chung Tú Đoàn haha, yeah it does need a jvm and everything. Though if you can use open-jdk as your base image, I’ve found it has a smaller memory footprint than other widely used java base docker images

[@philsmart11]

Benefits over a runnable jar with mutable, externalised config?

[@RajeshSamson]

How to set the exclude devtools option with Gradle??

[@azulamazigh2789]

what does the secret do and the argument for remote spring app (file watcher)?!!

[@BrunoDrugowick]

I was also wondering, but I guess maybe Dev Tools on the remote app validates what the Spring Remote sends through this key. Let's see if someone who is sure appears on this thread.

[@deepak2all]

The link gives details all new features of 2.3 version of spring boot incl docker image support

[@BrunoDrugowick]

@@deepak2all It doesn't answer the question. This video is more specific than the one you linked and doesn't answer the question.

[@prasannakumar-kx8uw]

do we need to have docker installed in our pc to build a docker

[@b0roovka]

Is there any docker compose integration to restart the service after build? Or it will just work by default?

[@prashantchaturvedi9919]

Giving it a try right away

[@4everchristi]

i get this error Step 2/4 : ARG JAR_FILE=target/*.jar ---> Running in d282ba096f92 Removing intermediate container d282ba096f92 ---> 7cb43248a488 Step 3/4 : COPY ${JAR_FILE} app.jar COPY failed: no source files were specified any idea how to solve it?

[@igortroy]

which dockerfile does it use?

[@Yena_394]

doesn't work on windows 10, running build-image returns error : [INFO] I/O exception (java.io.FileNotFoundException) caught when processing request to {}->docker://localhost:2376: \\.\pipe\docker_engine (The system cannot find the file specified)

[@andreaschrist4093]

You have to start Docker host first.

[@clivescott4645]

Amazing stuff!

[@alpercezibarak651]

But, is it possible to debug your code with IntelliJ when using docker container in local?

[@michaelrusso558]

You'd have to configure the JVM in the container for remote debugging and point IntelliJ at the remote debugging port, same as if you were to debug any Java application on another server

[@ray5843]

Great work!

[@Milandor]

Awesome feature!

[@kpmonaghan]

This is awesome!

[@Anbu_Sampath]

Great work...

[@kamalhm-dev]

What keyboard shortcut u use to rebuild the app?

[@jef-]

I think on Mac is cmd+f9. You can also remap any keys. JetBrains has a good write up on these.

[@dominikseljan3043]

On windows, it’s ctrl+F9

Goodbye immutable code for specific version. Think twice if you want to use it for non-dev environment
