1 安装docker

网上都有，这一点不必赘述

问题： 配置完成后，进行拉取软件，有时会遇到

Error response from daemon: Get “https://registry-1.docker.io/v2/“: net/http: request cancele

1. 1 修改镜像源

修改docker镜像源：

vim /etc/docker/daemon.json

{
"registry-mirrors": [
"https://2a6bf1988cb6428c877f723ec7530dbc.mirror.swr.myhuaweicloud.com",
"https://docker.m.daocloud.io",
"https://hub-mirror.c.163.com",
"https://mirror.baidubce.com",
"https://your_preferred_mirror",
"https://dockerhub.icu",
"https://docker.registry.cyou",
"https://docker-cf.registry.cyou",
"https://dockercf.jsdelivr.fyi",
"https://docker.jsdelivr.fyi",
"https://dockertest.jsdelivr.fyi",
"https://mirror.aliyuncs.com",
"https://dockerproxy.com",
"https://mirror.baidubce.com",
"https://docker.m.daocloud.io",
"https://docker.nju.edu.cn",
"https://docker.mirrors.sjtug.sjtu.edu.cn",
"https://docker.mirrors.ustc.edu.cn",
"https://mirror.iscas.ac.cn",
"https://docker.rainbond.cc"
]
}

systemctl daemon-reload

systemctl restart docker

1. 2 修改DNS配置

vim /etc/resolv.conf

增加

nameserver 114.114.114.114

此时，也许不能使用 docker search 软件 的版本，但是能够进行pull

2 dock-compose编排

version: "3.8"

services:

nginx:

image: nginx

container_name: web

ports:

• "80:80"

volumes:

• ./nginx/nginx.conf:/etc/nginx/nginx.conf

• ./nginx/conf.d:/etc/nginx/conf.d

networks:

• net1

serverjar:

image: serverjar

container_name: serverjar

ports:

• "8888:8888"

networks:

• net1

rabbitmq:

image: rabbitmq:management

container_name: rabbitmq

节点名 rabbit@rabbitserver，不然会去容器ID

hostname: rabbitserver

environment:

默认虚拟机名

RABBITMQ_DEFAULT_VHOST: admin_vhost

用户名

RABBITMQ_DEFAULT_USER: guest

密码

RABBITMQ_DEFAULT_PASS: guest

ports:

• "5672:5672"

• "15672:15672"

volumes:

• ./rabbitmq/data:/var/lib/rabbitmq

networks:

• net1

postgresql:

image: postgres

container_name: postgresql

environment:

  POSTGRES_DB: postgres

  POSTGRES_USER: "root"

  POSTGRES_PASSWORD: "root"

ports:

- 5432:5432

networks:

- net1

volumes:

- ./postgres/data:/var/lib/postgresql/data

redis:

image: redis

container_name: redis

ports:

- '6379:6379'

volumes:

- ./redis/data:/data

- ./redis/conf:/etc/redis/

- ./redis/logs:/logs

command: ["redis-server","/etc/redis/redis.conf"]

networks:

net1:

docker compose up 便依次启动

2.1 nginx

docker pull nginx //下载nginx

复制主要的文件

将自己的前端包放在html下

2.2 redis

拉取镜像 docker pull redis
创建redis专用目录 mkdir -p redis/{conf,data}
创建配置文件 vim redis/conf/redis.conf

#允许任何主机访问redis

bind 127.0.0.1

#禁用保护模式
protected-mode no
#端囗6379(默认)
port 6379
#不允许守护进程模式(设置允许与参数-d冲突，容器无法启动)
daemonize no
#访问密码
requirepass 123456

2.3 制作java镜像

提取码：xuxq

mdkir jdk

将网盘下载的资源包jdk-8u131-linux-x64.tar.gz 放在jdk文件夹下，

vim Dockerfile

FROM centos:centos7

RUN mkdir /usr/local/jdk （如果存在该目录不需执行此步）

WORKDIR /usr/local/jdk

ADD jdk-8u131-linux-x64.tar.gz /usr/local/jdk

ENV JAVA_HOME /usr/local/jdk/jdk1.8.0_131

ENV JRE_HOME /usr/local/jdk/jdk1.8.0_131/jre

ENV PATH $JAVA_HOME/bin:$PATH

构建镜像 docker build -t jdk:1.8 .

2.4 构建微服务镜像serverjar

vim Dockerfile

FROM jdk:1.8

COPY jar1 /jar/

EXPOSE 8888

COPY start.sh /jar/start.sh

RUN chmod +x /jar/start.sh

ENTRYPOINT ["sh","/jar/start.sh"]

start.sh 可以写

#!/bin/sh

java -jar jar1 & sleep 60 &

java -jar jar2

& sleep 60 & 是为了两个包之间间隔60s启动，也可以不需要

docker build -t serverjar .
