基於 Alpine Linux 的 Docker 基礎鏡像構建

基於 Alpine Linux 的 Docker 基礎鏡像構建

使用 MINI ROOT FILESYSTEM 版的Linux文件
此版本官方稱爲最小的文件系統(Minimal root filesystem. For use in containers and minimal chroots.).

1. 下載 alpine-minirootfs 文件

alpine-minirootfs-3.8.0-x86_64.tar.gz

2. 導入 tar 文件生成初始鏡像

docker import -m "use alpine-minirootfs-3.8.0-x86-64.tar.gz" alpine-minirootfs-3.8.0-x86-64.tar.gz alpine-3.8.0-base-image:1.0

3. 編寫 Dockerfile 文件

# 完整版 Dockerfile
FROM alpine-3.8.0-base-image:1.0
CMD ["/bin/sh"]
# 默認掛載的 jdk 目錄
VOLUME /opt/java/default-jdk
ENV LANG=C.UTF-8
ENV LANG=zh_CN.UTF-8
ENV LANGUAGE=zh_CN:zh
ENV LC_ALL=zh_CN.UTF-8
ENV LC_ALL=zh_CN.UTF-8
ENV TZ=Asia/Shanghai
# jdk 環境變量配置
ENV JAVA_HOME=/opt/java/default-jdk
ENV PATH=${PATH}:${JAVA_HOME}/bin
# 安裝 glibc; 配置鏡像源,安裝 tzdata bash curl

	echo -e "https://mirror.tuna.tsinghua.edu.cn/alpine/v3.8/main\nhttps://mirror.tuna.tsinghua.edu.cn/alpine/v3.8/community" > /etc/apk/repositories && \

    ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone && \
    \
    rm "/etc/apk/keys/sgerrand.rsa.pub" && \
    /usr/glibc-compat/bin/localedef --force --inputfile POSIX --charmap UTF-8 "$LANG" || true && \
    echo "export LANG=$LANG" > /etc/profile.d/locale.sh && \
    \
    apk del glibc-i18n && \
    \
    rm "/root/.wget-hsts" && \
    apk del .build-dependencies && \
    rm \
        "$ALPINE_GLIBC_BASE_PACKAGE_FILENAME" \
        "$ALPINE_GLIBC_BIN_PACKAGE_FILENAME" \
        "$ALPINE_GLIBC_I18N_PACKAGE_FILENAME"

4.使用Dockerfile構建基礎鏡像

docker build --force-rm --rm --no-cache -t alpine-3.8.0-docker-image:1.0 .
