安装docker
比较简单，可以参考菜鸟教程
修改配置文件
vi /lib/systemd/system/docker.service
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
BindsTo=containerd.service
After=network-online.target firewalld.service containerd.service
Wants=network-online.target
Requires=docker.socket
[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
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always
# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3
# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
[Install]
WantedBy=multi-user.target
vim /etc/docker/daemon.json
{
"hosts": ["unix:///var/run/docker.sock", "tcp://0.0.0.0:2375"]
}
重启docker
systemctl daemon-reload
service docker restart
访问http://ip:2375/version，看到版本信息即成功
编写Dockerfile
跟pom.xml文件同级处创建Dockerfile
FROM openjdk:8-jre
ARG JAR_FILE
ADD target/$JAR_FILE /app.jar
ENTRYPOINT ["java", "-jar", "-Duser.timezone=GMT+08", "/app.jar"]
在IDEA新建Docker服务
按照下图所示创建DockerServer

配置系统环境变量DOCKER_HOST
