IDEA部署springcloud到docker

一.修改docker端口

sudo vim /lib/systemd/system/docker.service

1、添加 ExecStart=/usr/bin/dockerd -H fd:// -H tcp://0.0.0.0:2375

2、注释掉(即在这行命令前加#) ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock ：

sudo vim /etc/default/docker

1、添加一行 DOCKER_OPTS="-H=unix:///var/run/docker.sock -H=0.0.0.0:2375"

重启服务

systemctl daemon-reload

service docker restart

验证：

curl http://localhost:2375/version

关闭防火墙

chkconfig iptables off

二：IDEA配置

1.配置连接到docker服务器

2.测试项目代码

DockerfileFROM java:8

VOLUME /tmp
COPY target/springboot-0.0.1-SNAPSHOT.jar demo.jar
RUN bash -c "touch /demo.jar"
EXPOSE 8099
ENTRYPOINT ["java","-jar","demo.jar"]
