Are you using Nixpacks or a custom Dockerfile?

ٴٴٴ•6mo ago

Custom dockerfile:

FROM openjdk:19
ADD ./docker-spring-boot.jar docker-spring-boot.jar
ENTRYPOINT ["java", "-jar", "docker-spring-boot.jar"]

FROM openjdk:19
ADD ./docker-spring-boot.jar docker-spring-boot.jar
ENTRYPOINT ["java", "-jar", "docker-spring-boot.jar"]

Are you building your app in the Dockerfile or manually?

ٴٴٴ•6mo ago

manually

root•6mo ago

Why?

ٴٴٴ•6mo ago

I am new in docker and deployment it's my first time, so idk how to do it correctly, just what i see in youtube and documentation ( Can we get a call? if it's possible?

Please don't do that. Here's a Dockerfile that should work out of the box:

FROM eclipse-temurin:19-jdk AS build
COPY . /app
WORKDIR /app
RUN ./gradlew bootJar
RUN mv -f build/libs/*.jar app.jar

FROM eclipse-temurin:19-jre
ARG PORT
ENV PORT=${PORT}
COPY --from=build /app/app.jar .
RUN useradd runtime
USER runtime
ENTRYPOINT [ "java", "-Dserver.port=${PORT}", "-jar", "app.jar" ]

FROM eclipse-temurin:19-jdk AS build
COPY . /app
WORKDIR /app
RUN ./gradlew bootJar
RUN mv -f build/libs/*.jar app.jar

FROM eclipse-temurin:19-jre
ARG PORT
ENV PORT=${PORT}
COPY --from=build /app/app.jar .
RUN useradd runtime
USER runtime
ENTRYPOINT [ "java", "-Dserver.port=${PORT}", "-jar", "app.jar" ]

Also, you shouldn't be getting unsupported version errors with Java 20 - it's perfectly well supported.

Oh, you're using Maven

ٴٴٴ•6mo ago

yep

root•6mo ago

that's a whole 'nother can of bean-shaped worms Would it be possible for you to use gradle?

ٴٴٴ•6mo ago

i should refactor whole project 😭

root•6mo ago

I'm afraid I can't really help you if you're using maven, I don't know much about it and I don't really want to touch it

ٴٴٴ•6mo ago

that is the problem with maven?

root•6mo ago

It's very slow and kind of outdated You should be able to start a new Spring Boot project with either https://railway.app/template/Wm9zSM or Spring Initializr and then copy your source files in, and it should basically work Using Gradle shouldn't really require code changes

ٴٴٴ•6mo ago

Oh, nice thanks, i will still try to do it with maven, but next projects i will use gradle, thank you a lot
