使用alpine镜像时,在dockerfile中修改语言环境

• dockerfile如下:

  FROM alpine:3.6
  
  # Install language pack
  RUN apk --no-cache add ca-certificates wget && \
      wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub && \
      wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.25-r0/glibc-2.25-r0.apk && \
      wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.25-r0/glibc-bin-2.25-r0.apk && \
      wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.25-r0/glibc-i18n-2.25-r0.apk && \
      apk add glibc-bin-2.25-r0.apk glibc-i18n-2.25-r0.apk glibc-2.25-r0.apk
  
  COPY ./locale.md /locale.md
  RUN cat locale.md | xargs -i /usr/glibc-compat/bin/localedef -i {} -f UTF-8 {}.UTF-8
  
  ENV LANG=en_US.UTF-8 \
      LANGUAGE=en_US.UTF-8
  

• 同级目录下创建 locale.md 文件，将以下内容拷贝入 locale.md：
