Docker之nginx部署

#glibc安装包如果从网络下载速度实在是太慢了,先提前下载复制到镜像中

COPY glibc-2.29-r0.apk /usr/local/java/

COPY glibc-bin-2.29-r0.apk /usr/local/java/

COPY glibc-i18n-2.29-r0.apk /usr/local/java/

COPY msg.jar /usr/local/java/

#更新Alpine的软件源为阿里云,因为从默认官源拉取实在太慢了

RUN echo http://mirrors.aliyun.com/alpine/v3.10/main/ > /etc/apk/repositories && \

echo http://mirrors.aliyun.com/alpine/v3.10/community/ >> /etc/apk/repositories

RUN apk update && apk upgrade

#运行指定的命令

#Alpine linux为了精简本身并没有安装太多的常用软件,apk类似于ubuntu的apt-get,

#用来安装一些常用软V件,其语法如下：apk add bash wget curl git make vim docker

#wget是linux下的ftp/http传输工具,没安装会报错“/bin/sh: wget: not found”,网上例子少安装wget

#ca-certificates证书服务,是安装glibc前置依赖

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 \

&& apk add glibc-2.29-r0.apk glibc-bin-2.29-r0.apk glibc-i18n-2.29-r0.apk \

&& rm -rf /var/cache/apk/* glibc-2.29-r0.apk glibc-bin-2.29-r0.apk glibc-i18n-2.29-r0.apk
