dockerfile构建javaweb镜像等系列操作

# 先构建 tomcat + jdk 的环境镜像， 后续再将war文件放入，在生成新镜像

[root@k8s-master dockerfile]# ls
apache-tomcat-9.0.30  apache-tomcat-9.0.30.tar.gz  dockerfile  jdk1.8.0_241  jdk-8u241-linux-x64.tar.gz

# dockerfile文件内容
[root@k8s-master dockerfile]# cat dockerfile

# 构建镜像
[root@k8s-master dockerfile]# docker build -t="wzllzw/tomcat" .

# 环境镜像构建到此完成

# 将war文件放入容器
[root@k8s-master dockerfile]# docker cp myapp_1.war tomcat_wzl:/usr/local/apache-tomcat-9.0.30/webapps
# 将容器生成新的镜像
[root@k8s-master dockerfile]# docker commit -a "[email protected]" 56c4f6fb99cb wzllzw/myapp:0.0.1

# 登录阿里云
