1.下载一个tomcat8,解压好改名为tomcat并配置端口为80,删除webapps下的默认的应用,修改tomcat/bin目录下脚本的权限,chmod +x *.sh
2.路径一般放在/usr/local目录下
2.编写Dockerfile如下:
FROM mcr.microsoft.com/java/jre:8u192-zulu-alpine
LABEL container="XX"
COPY tomcat /usr/local/tomcat
ENV TZ=Asia/Shanghai
ENV CATALINA_HOME=/usr/local/tomcat
ENV CATALINA_BASE=/usr/local/tomcat
ENV PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/tomcat/lib:/usr/local/tomcat/bin
EXPOSE 80
CMD ["catalina.sh", "run"]
执行命令
docker build -t tomcat:8-jre8-alpine .
创建镜像
执行命令docker images|grep tomcat
查看镜像
过程中遇到的问题:
解决办法:
代理服务器使用proxy
mkdir -p ~/proxy
cd ~/proxy
cat <<EOF >>startup.sh
#!/bin/sh
docker rm -f tinyproxy
docker run -d --name tinyproxy -p 8888:8888 dannydirect/tinyproxy:latest ANY
EOF
chmod +x startup.sh
./startup.sh
docker通过代理
这一步可以使服务器的docker命令通过代理(docker search、push、pull、login等)
mkdir -p /etc/systemd/system/docker.service.d/
cat <<EOF > /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=http://172.19.20.100:8888" "NO_PROXY=registry-hz.fpi-inc.site"
EOF systemctl daemon-reload systemctl restart docker
