Docker实用篇
Docker是一个快速交付应用、运行应用的技术，具备下列优势：
- 可以将程序及其依赖、运行环境包括系统函数库，一起打包为一个镜像，仅依赖系统的Linux内核，可以迁移到任意Linux操作系统
- 运行时利用沙箱机制形成隔离容器，各个应用互不干扰
- 启动、移除都可以通过一行命令完成，方便快捷
安装Docker
[root@test ~]# yum remove docker docker-client docker-client-latest docker-common \
docker-latest docker-latest-logrotate docker-logrotate docker-selinux \
docker-engine-selinux docker-engine docker-ce
[root@test ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 --skip-broken

[root@test ~]# docker -v
Docker version 20.10.14, build a224086
docker官方镜像仓库网速较差，我们需要设置国内镜像服务：
参考阿里云的镜像加速文档：https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://n0dwemtq.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

数据卷（容器数据管理）
数据卷操作的基本语法如下：
[root@docker ~]# docker volume --help
Usage: docker volume COMMAND
Commands:
create Create a volume
inspect Display detailed information on one or more volumes
ls List volumes
prune Remove all unused local volumes
rm Remove one or more volumes
① 创建数据卷
[root@docker ~]# docker volume create test-vo
[root@docker ~]# docker volume ls
DRIVER VOLUME NAME
local test-vo
[root@docker ~]# docker volume inspect test-vo
[
{
"CreatedAt": "2022-03-31T12:00:25+08:00",
"Driver": "local",
"Labels": {},
"Mountpoint": "/var/lib/docker/volumes/test-vo/_data",
"Name": "test-vo",
"Options": {},
"Scope": "local"
}
]
挂载数据卷到容器内的HTML目录
docker run --name nginx -v test-vo:/usr/share/nginx/html -p 80:80 -d nginx
#如果volmue： test-vo不存在，则自动创建
去DockerHub查阅资料，创建并运行MySQL容器
docker run --name myslq-test -e MYSQL_PASSWOED=123 -p3306:3306 \
-v /tmp/mysql/conf/my1.cnf:/etc/mysql/conf.d/my1.cnf \
-v /tmp/myslq/data:/var/lib/mysql -d myslq:5.7.25
Dockerfile语法
镜像是将应用程序及其需要的系统函数库、环境、配置、依赖、启动脚本打包在一起形成的文件。
1）Dockerfile语法
FROM 基础镜像
RUN 制作镜像时执行的命令，可以有多个
ADD 复制文件到镜像，自动解压
COPY 复制文件到镜像，不解压
EXPOSE 声明开放的端口
ENV 设置容器启动后的环境变量
WORKDIR 定义容器默认工作目录（指定目录等于cd，会自动创建)
CMD 容器启动时执行的命令，仅可以有一条CMD
ENTERPOINT 器启动时执行的命令,会覆盖CMD
2）使用Dockerfile创建镜像制作镜像
docker build -t image:tag Dockerfile所在目录
需求：基于Ubuntu镜像构建一个新镜像，运行一个java项目
# 指定基础镜像
FROM ubuntu:16.04
# 配置环境变量，JDK的安装目录
ENV JAVA_DIR=/usr/local
# 拷贝jdk和java项目的包
COPY ./jdk8.tar.gz $JAVA_DIR/
COPY ./docker-demo.jar /tmp/app.jar
# 安装JDK
RUN cd $JAVA_DIR \
&& tar -xf ./jdk8.tar.gz \
&& mv ./jdk1.8.0_144 ./java8
# 配置环境变量
ENV JAVA_HOME=$JAVA_DIR/java8
ENV PATH=$PATH:$JAVA_HOME/bin
# 暴露端口
EXPOSE 8090
# 入口，java项目的启动命令
ENTRYPOINT java -jar /tmp/app.jar
DockerCompose
Docker Compose可以基于Compose文件帮我们快速的部署分布式应用，实现容器编排。
Compose文件是一个文本文件，通过指令定义集群中的每个容器如何运行。
DockerCompose的详细语法参考官网：https://docs.docker.com/compose/compose-file/
格式如下：
version: "3.8"
services:
//运行mysql设置了环境变量，挂载了目录
mysql:
image: mysql:5.7.25
environment:
MYSQL_ROOT_PASSWORD: 123
volumes:
- "/tmp/mysql/data:/var/lib/mysql"
- "/tmp/mysql/conf/hmy.cnf:/etc/mysql/conf.d/hmy.cnf"
//等于构建镜像后docker run --name web -p 8090:8090 -d build的镜像
web:
build: .
ports:
- "8090:8090"
安装DockerCompose
Linux下需要通过命令下载：
[root@docker ~]# curl -L https://github.com/docker/compose/releases/download/1.23.1/docker-compose-`uname -s`-`uname -m` \
> /usr/local/bin/docker-compose
[root@docker ~]# chmod +x /usr/local/bin/docker-compose
[root@docker ~]# echo "199.232.68.133 raw.githubusercontent.com" >> /etc/hosts
[root@docker ~]# curl -L https://raw.githubusercontent.com/docker/compose/1.29.1/contrib/completion/bash/docker-compose \
> /etc/bash_completion.d/docker-compose
[root@docker ~]# docker-compose -v
docker-compose version 1.29.1, build c34c88b2
[root@docker ~]# docker-compose --help
Define and run multi-container applications with Docker.

部署微服务集群
需求：将cloud-demo微服务集群利用DockerCompose部署
[root@docker cloud-demo]# ls
docker-compose.yml gateway mysql order-service user-service
[root@docker cloud-demo]# tree gateway/
gateway/
├── app.jar
└── Dockerfile
order-service/
├── app.jar
└── Dockerfile
user-service/
├── app.jar
└── Dockerfile
[root@docker cloud-demo]# ls mysql/data/
cloud_user cloud_order
[root@docker cloud-demo]# cat /user-service/Dockerfile
FROM java:8-alpine
COPY ./app.jar /tmp/app.jar
ENTRYPOINT java -jar /tmp/app.jar
[root@docker cloud-demo]# cat docker-compose.yml
version: "3.2"
services:
nacos:
image: nacos/nacos-server
environment:
MODE: standalone
ports:
- "8848:8848"
mysql:
image: mysql:5.7.25
environment:
MYSQL_ROOT_PASSWORD: 123
volumes:
- "$PWD/mysql/data:/var/lib/mysql"
- "$PWD/mysql/conf:/etc/mysql/conf.d/"
userservice:
build: ./user-service
orderservice:
build: ./order-service
gateway:
build: ./gateway
ports:
- "10010:10010"
可以看到，其中包含5个service服务：
nacos：作为注册中心和配置中心image: nacos/nacos-server： 基于nacos/nacos-server镜像构建environment：环境变量MODE: standalone：单点模式启动
ports：端口映射，这里暴露了8848端口
mysql：数据库image: mysql:5.7.25：镜像版本是mysql:5.7.25environment：环境变量MYSQL_ROOT_PASSWORD: 123：设置数据库root账户的密码为123
volumes：数据卷挂载，这里挂载了mysql的data、conf目录，其中有我提前准备好的数据
userservice、orderservice、gateway：都是基于Dockerfile临时构建的
修改微服务配置
因为微服务将来要部署为docker容器，而容器之间互联不是通过IP地址，而是通过容器名。这里我们将order-service、user-service、gateway服务的mysql、nacos地址都修改为基于容器名的访问。
spring:
datasource:
url: jdbc:mysql://mysql:3306/cloud_order?useSSL=false
username: root
password: 123
driver-class-name: com.mysql.jdbc.Driver
application:
name: orderservice
cloud:
nacos:
server-addr: nacos:8848 # nacos服务地址
微服务的打包
Dockerfile中的jar包名称都是app.jar，因此我们的每个微服务都需要用这个名称。
可以通过修改pom.xml中的打包名称来实现，每个微服务都需要修改：
<build>
<!-- 服务打包的最终名称 -->
<finalName>app</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
进入cloud-demo目录，然后运行下面的命令：
docker-compose up -d
搭建私有镜像仓库
搭建镜像仓库可以基于Docker官方提供的DockerRegistry来实现
简单版
docker run -d --restart=always --name registry -p 5000:5000 \
-v registry-data:/var/lib/registry registry
带有图形化界面版本
使用DockerCompose部署带有图象界面的DockerRegistry
[root@docker ~]# mv registry.yaml compose.yml
version: '3.0'
services:
registry:
image: registry
volumes:
- ./registry-data:/var/lib/registry
ui:
image: joxit/docker-registry-ui:static
ports:
- 8080:80
environment:
- REGISTRY_TITLE=私有仓库
- REGISTRY_URL=http://registry:5000
depends_on:
- registry
私服采用的是http协议，默认不被Docker信任，所以需要做一个配置：
[root@docker cloud-demo]# vi /etc/docker/daemon.json
"insecure-registries":["http://192.168.1.17:8080"],
[root@docker cloud-demo]# systemctl daemon-reload
[root@docker cloud-demo]# systemctl restart docker
[root@docker ~]# docker-compose up -d
Creating root_registry_1 ... done
Creating root_ui_1 ... done
浏览器访问192.168.1.17:8080/，可以看到仓库信息
推送、拉取镜像
重新tag本地镜像，名称前缀为私有仓库的地址：192.168.150.101:8080/
[root@docker ~]# docker tag nginx:latest 192.168.1.17:8080/nginx:1.0
[root@docker ~]# docker push 192.168.1.17:8080/nginx:1.0
[root@docker ~]# docker pull 192.168.1.17:8080/nginx:1.0
浏览器访问192.168.1.17:8080/ 可以看到镜像信息，大小，历史
部署企业私有镜像仓库Habor
1）开启路由转发
[root@harbor ~]# echo 'net.ipv4.ip_forward = 1' >> /etc/sysctl.conf
[root@harbor ~]# sysctl -p
[root@harbor ~]# yum -y install docker-ce
[root@harbor ~]# systemctl start docker
[root@harbor ~]# systemctl enable docker
2）部署harbor
[root@harbor ~]# mv /root/docker-compose /usr/local/bin/
[root@harbor ~]# chmod +x /usr/local/bin/docker-compose
[root@harbor ~]# tar -xf harbor-offline-installer-v1.2.0.tgz -C /usr/local/
[root@harbor ~]# cd /usr/local/harbor
[rootharbor harbor]# ls
common docker-compose.notary.yml harbor_1_1_0_template harbor.v1.2.0.tar.gz
LICENSE prepare docker-compose.clair.yml docker-compose.yml harbor.cfg
install.sh NOTICE upgrade
3）修改配置文件
#访问harbor管理界面的地址，改为本机的IP地址
[root@harbor harbor]# sed -i '/^hostname/s/reg.mydomain.com/192.168.1.17/' harbor.cfg
[root@harbor harbor]# sed -i '121 s/80:80/8099:80/' docker-compose.yml
#默认是访问80端口，但因为80端口与Nginx集群冲突，故改变访问端口为8099
[root@harbor harbor]#sed -i '24 s/$ui_url/$ui_url:8099/' common/templates/registry/config.yml
[root@harbor harbor]# ./install.sh
.......
