下載alpine系統映象
[root@docker~]# docker pull alpine:3.14準備alpine映象原始檔
[root@docker~]# mkdir alpine [root@docker alpine]# vim repositories http://mirrors.aliyun.com/alpine/v3.14/main http://mirrors.aliyun.com/alpine/v3.14/community
編寫Dockerfile檔案
FROM alpine:3.14 #指定基礎映象 LABEL maintainer="[email protected]" #作者資訊 COPY repositories /etc/apk/repositories #拷貝映象原始檔 RUN apk update && apk --no-cache add iotop gcc libgcc libc-dev libcurl libc-utils pcre-dev zlib-dev libnfs make pcre pcre2 zip unzip net-tools pstree wget libevent libevent-dev iproute2 openjdk8-jre-base #安裝JDK及相關軟體包
構建基於alpine的JDK映象
[root@docker alpine]# docker build -t alpine-jdk:v1.8 . [root@docker alpine]# docker images alp* REPOSITORY TAG IMAGE ID CREATED SIZE alpine-jdk 8u212 d8be19eb2843 About a minute ago 598MB alpine 3.14 021b3423115f 2 weeks ago 5.6MB
從JDK映象構建tomcat 8 Base映象
下載tomcat安裝包
[root@docker ~]# mkdir tomcat &&cd tomcat
[root@docker tomcat]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.70/bin/apache-tomcat-8.5.70.tar.gz
編寫Dockerfile檔案

RUN ln -s /apps/apache-tomcat-8.5.70 /apps/tomcat

ENTRYPOINT ["/apps/tomcat/bin/catalina.sh","run"]構建基於alpine-JDK的tomcat映象

建立tomcat容器
[root@docker tomcat]# docker run -d -p 8080:8080 tomcat-base:v8.5.70
