I’ve just tried the new Alpaquita Containers. The result in my case was that
the image size went down from 370MB to 162MB.
That is about 56% less, which is pretty good !
How I tested it ?
I’ve used the example code from one of my previous articles How to Build a Spring Boot Monolith with JBang
if you want to try it yourself, you can clone the https://github.com/dmakariev/examples repository.
git clone https://github.com/dmakariev/examples.git
cd examples/jbang/spring-boot-jpa-vue
this will build the image based on amazoncorretto:21-alpine
docker compose build
then to build the image based on bellsoft/liberica-runtime-container:jdk-21-slim-musl
you have to execute the following
docker compose -f bellsoft-compose.yaml build
As I’ve written above - the result is 56% smaller image
you could see for yourself by executing
docker images
here is the output I received
REPOSITORY TAG IMAGE ID CREATED SIZE
spring-boot-jpa-vue_backend bellsoft 810e09bf2907 12 seconds ago 162MB
spring-boot-jpa-vue_backend aws-alpine d9e33d5a9219 About a minute ago 370MB
Give them a try, you can browse the images here https://hub.docker.com/r/bellsoft/alpaquita-linux-base
Thanks and..
Happy coding!
