一 工作目录

root@k8s-harbor-01:/data/dockerfile/system/alpine-glibc# pwd
/data/dockerfile/system/alpine-glibc

二 下载glibc

root@k8s-harbor-01:/data/dockerfile/system/alpine-glibc# wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.34-r0/glibc-2.34-r0.apk

三 编写Dockerfile

root@k8s-harbor-01:/data/dockerfile/system/alpine-glibc# cat Dockerfile 
FROM alpine:3.15

COPY glibc-2.34-r0.apk /tmp
RUN echo \
        "-----BEGIN PUBLIC KEY-----\
        MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEApZ2u1KJKUu/fW4A25y9m\
        y70AGEa/J3Wi5ibNVGNn1gT1r0VfgeWd0pUybS4UmcHdiNzxJPgoWQhV2SSW1JYu\
        tOqKZF5QSN6X937PTUpNBjUvLtTQ1ve1fp39uf/lEXPpFpOPL88LKnDBgbh7wkCp\
        m2KzLVGChf83MS0ShL6G9EQIAUxLm99VpgRjwqTQ/KfzGtpke1wqws4au0Ab4qPY\
        KXvMLSPLUp7cfulWvhmZSegr5AdhNw5KNizPqCJT8ZrGvgHypXyiFvvAH5YRtSsc\
        Zvo9GI2e2MaZyo9/lvb+LbLEJZKEQckqRj4P26gmASrZEPStwc+yqy1ShHLA0j6m\
        1QIDAQAB\
        -----END PUBLIC KEY-----" | sed 's/   */\n/g' > "/etc/apk/keys/sgerrand.rsa.pub" \
    && apk add /tmp/glibc-2.34-r0.apk \
    && rm -rf /tmp/glibc-2.34-r0.apk

四 编写构建镜像脚本

root@k8s-harbor-01:/data/dockerfile/system/alpine-glibc# cat build-command.sh 
#!/bin/bash
docker build -t  192.168.174.120/baseimages/alpine_glibc-base:3.15 .

#docker push 192.168.174.120/baseimages/alpine_glibc-base:3.15

五 构建镜像

root@k8s-harbor-01:/data/dockerfile/system/alpine-glibc# ./build-command.sh

六 提交镜像到harbor

root@k8s-harbor-01:/data/dockerfile/system/alpine-glibc# docker push 192.168.174.120/baseimages/alpine_glibc-base:3.15
