Quarkus运行时基础镜像
To ease the containerization of native executables, Quarkus provides a base image providing the requirements to run these executables. The quarkus-micro-image:2.0 image is:
-
小的 (基于
ubi8-micro) -
专为容器而设计的
-
包含正确的依赖项（glibc、libstdc++、zlib）
-
支持upx压缩的可执行文件（更多相关细节在 启用压缩文档 中）
使用此基础镜像
在你的 Dockerfile 中，只需使用:
FROM quay.io/quarkus/quarkus-micro-image:2.0
WORKDIR /work/
COPY target/*-runner /work/application
RUN chmod 775 /work
EXPOSE 8080
CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]扩展该镜像
你的应用程序可能有其他的额外要求。例如，如果你有一个依赖于 libfreetype.so 的应用程序，你需要将本地库拷贝到容器当中。在这种情况下，你需要使用一个多阶段的 dockerfile 来拷贝所需要的依赖库:
# First stage - install the dependencies in an intermediate container
FROM registry.access.redhat.com/ubi8/ubi-minimal:8.6 as BUILD
RUN microdnf install freetype
# Second stage - copy the dependencies
FROM quay.io/quarkus/quarkus-micro-image:2.0
COPY --from=BUILD \
/lib64/libfreetype.so.6 \
/lib64/libbz2.so.1 \
/lib64/libpng16.so.16 \
/lib64/
WORKDIR /work/
COPY target/*-runner /work/application
RUN chmod 775 /work
EXPOSE 8080
CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]如果你需要获得对AWT的完整支持，你需要的不仅仅是 libfreetype.so ，同时还需要字体和字体配置:
# First stage - install the dependencies in an intermediate container
FROM registry.access.redhat.com/ubi8/ubi-minimal:8.6 as BUILD
RUN microdnf install freetype fontconfig
# Second stage - copy the dependencies
FROM quay.io/quarkus/quarkus-micro-image:2.0
COPY --from=BUILD \
/lib64/libfreetype.so.6 \
/lib64/libgcc_s.so.1 \
/lib64/libbz2.so.1 \
/lib64/libpng16.so.16 \
/lib64/libm.so.6 \
/lib64/libbz2.so.1 \
/lib64/libexpat.so.1 \
/lib64/libuuid.so.1 \
/lib64/
COPY --from=BUILD \
/usr/lib64/libfontconfig.so.1 \
/usr/lib64/
COPY --from=BUILD \
/usr/share/fonts /usr/share/fonts
COPY --from=BUILD \
/usr/share/fontconfig /usr/share/fontconfig
COPY --from=BUILD \
/usr/lib/fontconfig /usr/lib/fontconfig
COPY --from=BUILD \
/etc/fonts /etc/fonts
WORKDIR /work/
COPY target/*-runner /work/application
RUN chmod 775 /work
EXPOSE 8080
CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]替代方案 - 使用 ubi-minimal
If the micro image does not suit your requirements, you can use ubi8/ubi-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.
要使用该基础镜像，使用以下 Dockerfile:
FROM registry.access.redhat.com/ubi8/ubi-minimal:8.6
WORKDIR /work/
RUN chown 1001 /work \
&& chmod "g+rwX" /work \
&& chown 1001:root /work
COPY --chown=1001:root target/*-runner /work/application
EXPOSE 8080
USER 1001
CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]
