docker安装和使用

1.安装

sudo yum install -y yum-utils \

  device-mapper-persistent-data \

  lvm2

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

sudo yum install docker-ce docker-ce-cli containerd.io

sudo systemctl start docker

systemctl enable docker.service

sudo docker run hello-world

1.1 换国内镜像

vim /etc/docker/daemon.json

{

    "registry-mirrors": ["https://bv8f9l6o.mirror.aliyuncs.com"]

}

systemctl restart docker.service

2.制作linux centos7v2镜像

docker pull centos:centos7

docker run -itd -p 10022:22 --name master --privileged=true -v /sys/fs/cgroup:/sys/fs/cgroup:ro centos:centos7 /usr/sbin/init

docker exec -it master bash

yum install -y net-tools.x86_64

yum install -y vim*

yum install -y openssh-server

vim/etc/ssh/sshd_config

PermitRootLogin  yes

yum install initscripts -y

service sshd restart

passwd

docker commit -a "luyu" -m "v2" master centos:centos7v2

3.制作centos7-jre8镜像

下载server-jre-8u201-linux-x64.tar.gz

编辑Dockerfile

FROM centos:centos7v2

COPY server-jre-8u201-linux-x64.tar.gz /usr/java/server-jre-8u201-linux-x64.tar.gz

RUN tar -zxvf /usr/java/server-jre-8u201-linux-x64.tar.gz -C /usr/java

RUN rm /usr/java/server-jre-8u201-linux-x64.tar.gz

ENV JAVA_HOME=/usr/java/jdk1.8.0_201

ENV PATH=$JAVA_HOME/bin:$PATH

ENV CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar

docker build -t centos:centos7-jre8 .

4.部署java服务

下载源码到编译路径

编译

编辑Dockerfile

FROM centos:centos7-jre8

RUN mkdir /kool

RUN mkdir /kool/soft

RUN mkdir /kool/soft/eops

RUN mkdir /kool/soft/eops/config

RUN mkdir /kool/soft/eops/proglog

COPY config/application.properties /kool/soft/eops/config/application.properties

COPY eops_init.sql /kool/soft/eops/eops_init.sql

COPY eops-0.0.1-SNAPSHOT.jar /kool/soft/eops/eops-0.0.1-SNAPSHOT.jar

COPY config/log4j2-spring.xml /kool/soft/eops/config/log4j2-spring.xml

COPY restart.sh /kool/soft/eops/restart.sh

RUN chmod +x /kool/soft/eops/restart.sh

COPY init_start.sh /etc/profile.d/init_start.sh

COPY init_start.sh /etc/init.d/init_start.sh

RUN chmod +x /etc/init.d/init_start.sh

RUN chkconfig --add init_start.sh

RUN chkconfig init_start.sh on

docker build -t eops:v1 .

导出镜像，导入到宿主机

docker run -itd -p 10022:22 -p 10101:10101 --name master --privileged=true -v /sys/fs/cgroup:/sys/fs/cgroup:ro eops:v1 /usr/sbin/init

docker exec -it master bash
