I have used jib and both multistage docker build and out of the box jib is not even close being as efficient as multistage docker build,maybe i did something wrong
Ive got 401 unauthorized while I try to start jibDockerBuild. What kind of password it needs. I don't understand. I tried to use my docker account with Auth but it doesn't work
Hi Ruslan. It sounds like it can't pull the base image. Presumably it can't authenticate with Docker Hub. I have 2 suggestions: 1) run "docker login" command first docs.docker.com/engine/reference/commandline/login/ 2) add "to.auth" configuration based on github.com/GoogleContainerTools/jib/tree/master/jib-gradle-plugin#to-closure
Hi Alexander. You can place a gradle.properties file in your user home directory ~/.gradle/gradle.properties with the key/value pair. Or use one of the other techniques highlighted in this video ruclips.net/video/BvXjlxJg2II/видео.html
Is it somehow possible to build images without having docker installed? I'd like to build docker image using jenkins pipeline without docker installed or any other plugins. Is it possible to build with maven or maven plugin without installing it.
Hi. Yes, you can use Jib to build Java applications into a Docker image, without Docker installed. It has a Maven plugin too. Check it out and let me know how you get on github.com/GoogleContainerTools/jib/tree/master/jib-maven-plugin
How can I find out what are the other options which I have in bootBuildImage apart from `--publishImage`? Apology for asking as I do not know how to find details for a particular task in Gradle
Check out the docs under "Image customisations". There is a column called "Command-line option" there docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/htmlsingle/#build-image
Hi. Apply and configure the chosen plugin within each subproject's build script. Remove duplication by extracting common logic into a convention plugin.
Hey Tom, as always thanks for a great vid! Im wondering what the benefit woul be with regards to using jib over a ‘normal’ dockerfile? And if it worth it in the long run?
Hi Willem. Thank you. One advantage of jib is that you can use it in environments where the Docker daemon is not available. That could be very helpful for some CI environments. Check out the full feature list in the accompanying article tomgregory.com/jib-vs-spring-boot-for-building-docker-images

Hi Tom, this is my very first YT comment in my life. Your content is absolutely fantastic! I really like to listen to your voice. Everything is clearly spoken, focused and to the point. Your topics are truly interesting even for me as an experienced java land resident. I am also a big fan of gradle and I still learn new things with your contributions. Keep up the good work! You really add value to the developer world.
Thank you very much, Tom, I am wondering is it possible to tag the images also? as pushing to the docker hub repository requires particular tagging for the image
Hi Mehdi. Good question! With the Jib Gradle plugin in build.gradle set "jib.to.tags". For the Spring Boot Gradle plugin it's "bootBuildImage.tags". Both of these take a list of tags.
OK, I'm using Spring Boot plugin 2.6.1. You might need to update then. Here are the docs docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/htmlsingle/#build-image
