Docker
docker 的安装
#安装yum的工具
yum install -y yum-utils
#添加阿里云docker镜像地址
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#更新yum软件包索引
yum makecache
#安装docker
yum install --allowerasing docker-ce docker-ce-cli containerd.io #不要用yum install docker-ce docker-ce-cli containerd.io安装，centos8内置了podman容器会冲突（是一个跟docker差不多的容器，因为centos8放弃了对docker的支持，代替方案就是podman）--allowerasing命令用于将要安装的包替代冲突的包
#启动docker
systemctl start docker
#开机自启
systemctl enable docker
docker启动mysql
# --name指定容器名字 -v目录挂载 -p指定端口映射 -e设置mysql参数 -d后台运行
docker run --name mysql -v /usr/local/mysql/data:/var/lib/mysql -v /usr/local/mysql:/etc/mysql -v /usr/local/mysql/log:/var/log/mysql -e MYSQL_ROOT_PASSWORD=lhc010516 -p 3306:3306 -d mysql:8.0.27
#进入docker里面mysql的目录
docker exec -it mysql /bin/bash
docker 启动 redis服务运行容器
# 启动redis服务运行容器
docker run --name redis -v /usr/local/redis/data:/data -v /usr/local/redis/redis.conf:/usr/local/etc/redis/redis.conf -p 6379:6379 -d redis:latest redis-server /usr/local/etc/redis/redis.conf
docker启动nginx
docker run --privileged=true -d --name nginx -p 8080:80 -v /usr/local/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/nginx/logs:/var/log/nginx -v /usr/local/nginx/html:/usr/share/nginx/html nginx
删除镜像
docker rmi -f (image id)
批量删除镜像
docker rmi -f $(docker images
#docker ps 命令
#列出当前正在运行的容器
-a#列出当前正在运行的容器+带出历史运行的容器
-n=？#列出最近创建的容器
-q #只显示容器的编号
退出容器
exit 直接退出容器
Ctrl + P + Q 容器不停止退出
删除容器
docker rm 容器id #删除指定的容器，不能删除正在运行的容器，强制运行 rm -f
docker rm -f $(docker ps -aq) #删除所有容器
启动和停止容器的操作
docker start 容器id # 启动容器
docker restart 容器id # 重启容器
docker stop 容器id # 停止当前正在运行的容器
docker kill 容器id #强制停止当前的容器
常用的命令
后台启动容器
docker run -d 镜像名称 #问题docker ps 发现 后台镜像停止了
#常见的坑：docker容器使用后台运行，就必须要有一个前台进程，docker发现没有应用就会停止
#nginx 容器启动后，发现自己没有提供服务，就会立刻停止，就是没有程序了
查看日志
#显示日志
-tf #显示日志
-n/--tail number #显示日志的条数
-f #保持打印窗口持续打印
-t #日志加时间
docker logs -tf -n 10 容器id
查看容器中进程信息
docker top 容器id
查看镜像元数据
#命令 docker inspect 容器id
#测试
docker inspect a1bd0008d904

#方式一
docker exec -it容器id /bin/bash
#方式二
docker attach 容器id#进入容器正在执行的终端，不会启动新的进程
从容器内拷贝文件到主机上
docker cp 容器id:容器内路径 目的主机路径

docker 安装tomcat
docker run -it --rm tomcat:9.0
#我们之前启动的都是后台，停止了容器还是可以查到，docker run -it --rm 用来测试，用完就删除
docker 安装ES镜像
docker pull nshou/elasticsearch-kibana
#最后咱们把镜像启动为容器就可以了，端口映射保持不变，咱们给这个容器命名为eskibana，到这里ES和Kibana就安装配置完成了！容器启动后，它们也就启动了，一般不会出错，是不是非常方便？节省大把时间放到开发上来，这也是我一直推荐docker的原因。
docker run -d -p 9200:9200 -p 9300:9300 -p 5601:5601 -e ES_JAVA_OPTS="-Xms64m -Xmx512m" --name eskibana nshou/elasticsearch-kibana
#咱们还需要安装ElasticSearch Head，它相当于是ES的图形化界面，这个更简单，它是一个浏览器的扩展程序，直接在chrome浏览器扩展程序里下载安装即可：
#打开chrome浏览器，在扩展程序chrome应用商店那里，搜索elasticsearch：

DockerFile
Dockerfile就是用来构建docker镜像的构建文件 --命令脚本
通过这个脚本可以生成镜像，镜像是一层层的，脚本一个个的命令，每个命令都是一层
docker build -f 脚本路径 -t 镜像id .
#test
[root@VM-0-4-centos ~]# docker build -f /root/dockerfile1 -t cong/docker:1.0 .

两个容器实现数据同步
docker run ..... -- volums -from 容器名称 镜像名称
容器间的信息传递 数据卷容器的生命周期一直持续到没有容器使用为止。
DockerFile构建过程
基础知识：
1 每个保留关键字（指令）都是必须是大写字母
2 执行从上到下顺序执行
3 #表示注释
4 每个指令都会创建提交一个新的
镜像层
dockerfile是面向开发的，我们以后要发布项目，做镜像，就需要编写dockerfile文件
FROM #基础镜像，一切从这里开始构建
MAINTAINER #镜像是谁写的，名字+邮箱
RUN #镜像构建的时候需要运行的命令
ADD #步骤：tomcat镜像, 这个tomcat的压缩包！添加内容
WORKDIR #镜像的工作目录
VOLUME #挂载的目录
EXPOSE #暴露端口配置
CMD #指定容器启动的时候要运行的命令，只有最后一个会生效，可被替代
ENTRYPOINT #指定这个容器启动的时候要运行的命令，可以直接追加命令
ONBUILD #当构建一个被继承 DockerFile这个时候就会运行 ONBUILD 的指令。触发指令
COPY #类似ADD，将我们文件拷贝到镜像中
ENV #构建的时候设置环境变量
实战测试
Docker Hub 中99%镜像都是从这个基础镜像过来的FROM scratch，然后配置需要的软件和配置
#1 编写dockerfile文件
[root@VM-0-4-centos dockerfile]# vim mydockerfile
[root@VM-0-4-centos dockerfile]# cat mydockerfile
FROM centos
MAINTAINER cong<771901874@qq.com>
EVA MYPATH /usr/local
WORKDIR $MYPATH
RUN yum -y install vim
RUN yum -y install net-tools
EXPOSE 80
CMD echo $MYPATH
CMD echo "---end---"
CMD /bin/bash
#2 通过文件构建对象
docker build -f mydockerfile -t mycentos:0.1 .
cmd 和 entrypointd的区别
CMD #指定容器启动的时候要运行的命令，只有最后一个会生效，可被替代
ENTRYPOINT #指定这个容器启动的时候要运行的命令，可以直接追加命令
实战：Tomcat
1 准备镜像文件 tomcat压缩包，jdk的压缩包
2 编写dockerfile文件，官方命名DockerFile
发布自己的镜像
DockerHub
1地址：https://hub.docker.com/注册自己的账号
2 确定这个账号可以启动
3 在我们的服务器上提交镜像
4登录完毕后就可以提交镜像，就是一步 docker push
[root@VM-0-4-centos dockerfile]# docker login

#易错点：docker push 后面必须加的是用户id/文件名字:tag 不然会报错
要用docker tag 命令来修改
阿里云镜像服务
1登录阿里云
2找到容器镜像服务
3创建命名空间
4创建容器镜像
1docker login --username=congdoraemon registry.cn-beijing.aliyuncs.com
2docker tag [ImageId] registry.cn-beijing.aliyuncs.com/lhcong-docker/cong-test:[镜像版本号]
3 docker push registry.cn-beijing.aliyuncs.com/lhcong-docker/cong-test:[镜像版本号]
Docker网络
理解Docker
#查看容器的内部网络地址 ip addr
docker exec -it 125227f233a9 ip addr
#若有报错在容器内执行下面的代码
apt update && apt install -y iproute2
#我们发现这个容器带来的网卡，都是一对对的
#ve th-pair 就是一对的虚拟设备接口，他们都是成对出现的，一段连着协议，一段彼此相连
docker使用的是linux的桥接
–link
自定义网络
查看所有的docker网络
[root@VM-0-4-centos ~]# docker network ls
NETWORK ID NAME DRIVER SCOPE
3fd008702217 bridge bridge local
2e08eb3e1445 host host local
f1063c44c7b8 none null local
网络模式
bridge :桥接 docker（默认，自己的创建也是用bridge模式）
none ：不配置网络
host ：和宿主机共享网络
container：容器网络连同！（用的少！局限很大）
#我们直接启动的命令 默认自带--net bridge ,而这个就是我的docker0
docker0特点：默认，域名不能访问， --link可以打通连接
docker network create --driver bridge
#test
[root@VM-0-4-centos ~]# docker network create --driver bridge --subnet 192.168.0.0/16 --gateway 192.168.0.1 mynet
f16708ce675cc5b9e3836c0052fba7a78b68ca71ad2d9d67feb4a5a4646921c3

好处：
redis -不同集群使用不同的网络，保证集群是安全和健康的
mysql-不同集群使用不同的网络，保证集群是安全和健康的
网络连通
#一个容器两个ip，打通。阿里云服务器： 公网ip 私网ip
redis集群部署
