编写Dockerfile
FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD xxpay4spring-boot.war app.jar
RUN sh -c 'touch /app.jar'
RUN /sbin/ip route|awk '/default/ { print  $3,"\tdockerhost" }' >> /etc/hosts
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
编译docker镜像
sudo docker build -t  xxpay4spring-boot:v1.0.0 .
打标签
sudo docker tag xxpay4spring-boot:v1.0.0 registry.cn-shanghai.aliyuncs.com/mengfanxiao/xxpay4spring-boot:v1.0.0
上传到阿里云docker镜像库
sudo docker push registry.cn-shanghai.aliyuncs.com/mengfanxiao/xxpay4spring-boot:v1.0.0
下载该镜像
sudo docker pull registry.cn-shanghai.aliyuncs.com/mengfanxiao/xxpay4spring-boot:v1.0.0
启动该镜像
docker run -d -p 8085:3020 registry.cn-shanghai.aliyuncs.com/mengfanxiao/xxpay4spring-boot:v1.0.0

docker search tomcat 
docker pull tomcat 
docker run -d -p 8088:8080 —name tomcat —restart=always tomcat
## 将war包复制进去docker tomcat中
docker cp /usr/local/testJavaProject/test01.war 9fccf0236619:/usr/local/tomcat/webapps
docker run  -p 8088:8080  -v /opt/project:/usr/local/tomcat/webapps  -d  tomcat

yum install wget
安装好了 wget 但没有生效
bash: wget: command not found
先yum remove wget 
再yum install wget
