docker配置运行远程访问

1、配置docker远程连接端口

 vi /usr/lib/systemd/system/docker.service

2、找到 ExecStart，在最后面添加 -H tcp://0.0.0.0:2375

[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375  ##这里添加
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always

3、重启docker

systemctl daemon-reload && systemctl start docker

4、开放端口和防火墙

firewall-cmd --zone=public --add-port=2375/tcp --permanent
iptables -I INPUT -p tcp --dport 2375 -j ACCEPT

5、验证

curl http://192.168.111.201:2375/version

IDEA远程访问

1、安装docker插件并重启

File->Settings->Plugins->Marketplace->搜索docker->Docker安装

2、配置连接远程docker

windows如果无法远程连接Docker(可略)

检查上一步配置远程连接是否成功，接着看下虚拟机是否有问题，下面各项需要全部打开

3、配置docker远程仓库

4、创建一个Dockerfile配置

5、打包镜像

这一步之前需要先将打个jar包，存放到dockerfile中指定的位置，可以在Run Maven Goal中执行先打jar包

clean package -U -DskipTests

Dockerfile示例

FROM openjdk:8-jdk
VOLUME /tmp
ARG JAR_FILE
COPY target/${JAR_FILE} app.jar
RUN apt-get install -y tzdata \
    && cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
    && dpkg-reconfigure -f noninteractive tzdata

ENTRYPOINT exec java $JAVA_OPTS $JASYPT_OPS -Djava.security.egd=file:/dev/./urandom -jar /app.jar
