Imagem de Tempo de Execução de Base do Quarkus
To ease the containerization of native executables, Quarkus provides a base image providing the requirements to run these executables.
The ubi9-quarkus-micro-image:2.0 image is:
-
small (based on
ubi9-micro) -
concebida para contêineres
-
contém o conjunto correto de dependências (glibc, libstdc++, zlib)
-
suporta executáveis comprimidos por upx (mais detalhes na documentação de ativação da compressão)
Usando a imagem de base
No seu Dockerfile, basta usar:
FROM quay.io/quarkus/ubi9-quarkus-micro-image:2.0
WORKDIR /work/
COPY --chmod=0755 target/*-runner /work/application
EXPOSE 8080
CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]Estendendo a imagem
Your application may have additional requirements.
For example, if you have an application that manipulates graphics, images, or PDFs, you likely have Quarkus AWT extension included in the project and your native executable will require some additional libraries to run.
In this case, you need to use a multi-stage dockerfile to copy the required libraries.
|
Copying handpicked libraries makes up for a small container image, yet it is somewhat britte, differs for different base image versions, and it is a subject to change as transitive dependencies of these libraries might change. |
|
Headless graphics, PDF documents, QR code images etc. manipulation is natively supported on amd64/aarch64 Linux only. Neither Windows nor MacOS are supported and require running the application in a Linux container. |
# First stage - install the dependencies in an intermediate container
FROM registry.access.redhat.com/ubi9/ubi-minimal:9.6 as nativelibs
RUN microdnf install -y freetype fontconfig expat
# Second stage - copy the dependencies

If the micro image does not suit your requirements, you can use ubi9-minimal.
It’s a bigger image, but contains more utilities and is closer to a full Linux distribution.
Typically, it contains a package manager (microdnf), so you can install packages more easily.
Para usar esta imagem de base, use o seguinte Dockerfile:
FROM registry.access.redhat.com/ubi9/ubi-minimal:9.6
WORKDIR /work/
RUN chown 1001 /work \
&& chmod "g+rwX" /work \
&& chown 1001:root /work
COPY --chown=1001:root --chmod=0755 target/*-runner /work/application
EXPOSE 8080
USER 1001
CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]To make documents processing, graphics, PDFs, etc. available for the application, you can install the required libraries using microdnf without manually copying anything:
FROM registry.access.redhat.com/ubi9/ubi-minimal:9.6
RUN microdnf install -y freetype fontconfig \
&& microdnf clean all
WORKDIR /work/
RUN chown 1001 /work \
&& chmod "g+rwX" /work \
&& chown 1001:root /work
# Shared objects to be dynamically loaded at runtime as needed
COPY --chown=1001:root target/*.so /work/
COPY --chown=1001:root --chmod=0755 target/*-runner /work/application
EXPOSE 8080
USER 1001
ENTRYPOINT ["./application", "-Dquarkus.http.host=0.0.0.0"]
