docker从安装到项目部署，超详细。

安装

1.安装命令如下：
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
也可以使用国内 daocloud 一键安装命令：
curl -sSL https://get.daocloud.io/docker | sh

2.查看docker相关信息

3.配置docker镜像加速

vi /etc/docker/daemon.json
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
} 

启动

4.启动 Docker。
$ sudo systemctl start docker
通过运行 hello-world 映像来验证是否正确安装了 Docker Engine-Community 。
$ docker run hello-world

5.启动一个容器

#启动nginx
docker run -d -p 80:80 nginx
#查看当前运行的容器
docker ps

镜像管理

1.根据镜像名称拉取镜像
docker pull

[root@VM-0-12-centos ~]# docker pull centos
Using default tag: latest
latest: Pulling from library/centos
7a0437f04f83: Pull complete 
Digest: sha256:5528e8b1b1719d34604c87e11dcd1c0a20bedf46e83b5632cdeac91b8c04efc1
Status: Downloaded newer image for centos:latest
docker.io/library/centos:latest

2.查看当前主机镜像列表

[root@VM-0-12-centos ~]# docker image list
REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
nginx         latest    f6d0b4767a6c   12 days ago     133MB
centos        latest    300e315adb2f   6 weeks ago     209MB
hello-world   latest    bf756fb1ae65   12 months ago   13.3kB

各个选项说明:
REPOSITORY：表示镜像的仓库源
TAG：镜像的标签
IMAGE ID：镜像ID
CREATED：镜像创建时间
SIZE：镜像大小

3.导出镜像

#查看

容器的日常管理

容器的起/停
启动：docker run 容器ID、名称
停止：docker stop 容器ID、名称

#启动容器
[root@VM-0-12-centos ~]# docker run -d -p 80:80 nginx

我们也可以使用 -p 标识来指定容器端口绑定到主机端口。
两种方式的区别是:
-P :是容器内部端口随机映射到主机的高端口。
-p : 是容器内部端口绑定到指定的主机端口。

查看正在运行容器*

[root@VM-0-12-centos ~]# docker ps

Docker 数据卷的管理

挂载时创建卷
挂载卷
docker run -it -v 宿主机路径:容器路径

#启动一个容器并挂载
docker run -it -v /app:/app --name vmount_cos centos /bin/bash

查看卷挂载路径

#查看正在运行容器
[root@VM-0-10-centos /]# docker ps
CONTAINER ID   IMAGE     COMMAND       CREATED          STATUS          PORTS     NAMES
a592f9c45485   centos    "/bin/bash"   14 minutes ago   Up 14 minutes             vmount_cos
#查看容器卷挂载路径
[root@VM-0-10-centos /]# docker inspect vmount_cos

匿名卷、具名卷
匿名：docker run -v 容器内路径 --name niming_centos centos /bin/bash

#匿名挂载
[root@VM-0-10-centos /]# docker run -d -v /r_ni --name niming_centos centos /bin/bash 

具名：[root@VM-0-10-centos /]# docker run -d -v 挂载名称:容器内路径

[root@VM-0-10-centos /]# docker run -d -v juming:/r_ju --name juming_centos centos /bin/bash

创建镜像

手动将容器保存为镜像
制作容器

将容器提交为镜像
docker commit 我们制作好的容器名称 制作好镜像名称

#容器制作成镜像
[root@VM-0-10-centos /]# docker commit vmount_cos vim_cos

Dockerfile自动构建docker镜像
指令
dockerfile主要组成部分：
基础镜像信息 FROM centos:6.8
制作镜像操作指令RUN yum insatll openssh-server -y
容器启动时执行指令 CMD ["/bin/bash"]
dockerfile常用指令：
FROM 这个镜像的妈妈是谁？（指定基础镜像）
MAINTAINER 告诉别人，谁负责养它？（指定维护者信息，可以没有）
RUN 你想让它干啥（在命令前面加上RUN即可）
ADD 给它点创业资金（COPY文件，会自动解压）
WORKDIR 我是cd,今天刚化了妆（设置当前工作目录）
VOLUME 给它一个存放行李的地方（设置卷，挂载主机目录）
EXPOSE 它要打开的门是啥（指定对外的端口）
CMD 奔跑吧，兄弟！（指定容器启动后的要干的事情）
dockerfile其他指令：
COPY 复制文件
ENV 环境变量
ENTRYPOINT 容器启动后执行的命令*
容器分层：

Dockerfile结构：

使用Dockerfile构建一个tomcat镜像，用来发布项目
编写Dcokerfile
vi Dockerfile

#基于sentos7系统构建镜像
FROM centos:7
#作者信息
MAINTAINER wjf<252717286@qq.com>
#将本地 jdk上传至容器 COPY 本地路径 >>容器路径
COPY ./jdk /usr/java/jdk
COPY ./tomcat_web /usr/local/tomcat_web
#配置环境
ENV JAVA_HOME /usr/java/jdk
ENV JRE_HOME $JAVA_HOME/jre
ENV CLASSPATH .:$JAVA_HOME/lib:$JRE_HOME/lib
ENV PATH $PATH:$JAVA_HOME/bin
#分配jvm运行大小
ENV CATALINA_OPTS -Xms128m -Xmx1024m -XX:PermSize=64M -XX:MaxPermSize=512M
#指定对外暴露的端口
EXPOSE 8091
#创建
RUN cd /usr/local/tomcat_web/logs && echo "1" >>count.txt
#启动容器后打印日志，每个人的日志地址不一样，根据自己路径来
ENTRYPOINT /usr/local/tomcat_web/bin/startup.sh && tail -F /usr/local/tomcat_web/logs/catalina.out

使用Dockerfile构建镜像
sudo docker build -t wjf_tomcat:v1 --rm=true .
#如果改变了Dockerfile名字，则需要指定 -f 文件名称

运行我们自己镜像

sudo docker run -p 8091:8091 --name --name wjf_tomcat01 wjf_tomcat:v1

如果想后台运行 可以在run后加 -d 参数即：sudo docker run -d -p 8091:8091 --name wjf_tomcat01 wjf_tomcat:v1 其余参数不解释，因为我们改过tomcat端口为8091，所以这里用8091

Docker网络

docker默认采用桥接方式进行网络通信，宿主机能够直接访问容器，容器也能直接访问宿主机，他们处于同一网关。
Docker网络类型关系

网络类型说明

同一个宿主机（服务器），多个容器互连
docker run --link 要连接容器名称

[root@VM-0-10-centos ~]# docker run --name d3 --link d1  -it centos
#查看映射关系
[root@9b8a70c798c2 /]# cat /etc/hosts
127.0.0.1       localhost
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.18.0.2      d1 ed9ceb35153e
172.18.0.4      9b8a70c798c2

自定义网络，实现不同宿主机（服务器），容器间互连

部署项目

至此，，我们就可以用docker容器发布自己的项目了，构建成自己的镜像，下面就准备开始实战
前端部署
利用Dockerfile构建ngnix镜像来部署vue包
1.先下载一个nginx镜像，运行。

#下载一个nginx镜像
[root@VM-0-10-centos ~]# docker pull nginx
#运行镜像并设置端口
[root@VM-0-10-centos ~]# docker run -d -p 80:80 nginx

创建nginx配置文件：
default.conf

# nginx配置
server {
    listen       80;
    server_name  localhost;
 
    #charset koi8-r;
    access_log  /var/log/nginx/host.access.log  main;
    error_log  /var/log/nginx/error.log  error;
 
    location / {
        # root 根目录，默认nginx镜像的html文件夹，可以指定其他
        root   /usr/share/nginx/html;
        index  index.html index.htm;
        # 如果vue-router使用的是history模式，需要设置这个 
        try_files $uri $uri/ /index.html;
    }
 
    #error_page  404              /404.html;
 
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

把配置文件上传到容器

#上传配置文件
docker cp defaut.conf c0682e96a4df:/etc/nginx/conf.d/default.conf
#上传打包好的vue代码到容器，也可以使用卷挂载
[root@VM-0-10-centos data]# docker cp webapp c0682e96a4df:/usr/share/nginx/html/
#到容器/usr/share/nginx/html移动文件
root@c0682e96a4df:/usr/share/nginx/html# mv -f ./webapp/* ./

配置完我们的nginx之后重启容器

#重启容器
[root@VM-0-10-centos data]# docker restart c0682e96a4df

测试连接，成功打开我们的前端项目

Dockerfile制作镜像部署我们的项目
首先创建一个Dockerfile文件
Dockerfile

#构建基础镜像
FROM nginx
#作者
MAINTAINER wjf
#拷贝本地vue包到nginx发布目录
COPY webapp/ /usr/share/nginx/html/
#拷贝我们创建配置文件覆盖nginx配置
COPY defaut.conf /etc/nginx/conf.d/default.conf

使用dockerfile创建镜像

 docker build -t website_web:1 .

运行我们自己构建的镜像，以后我们就可以把我们的镜像交给别人部署了

docker run -d  --name image_web -p 8080:80 website_web:1

测试连接8080,成功。

后端部署
利用jdk基础镜像构建部署我们的jar包
Dockerfile:

#基础镜像，jdk8
FROM openjdk:8u212-jre
#作者
MAINTAINER wjf
#将我们后端打包好的jar复制进容器当中
COPY febs-server-website.jar /febs/febs-server-website.jar
#容器启动运行我们的jar包
ENTRYPOINT ["java", "-Xmx256m", "-jar", "/febs/febs-server-website.jar"]

构建镜像

[root@VM-0-10-centos java]# docker build -t website_java:v1 .

运行后端镜像

 docker run --name website_java -d registry.cn-hangzhou.aliyuncs.com/wujiafu/wu_roup/website_java:v1

验证，成功。

至此，我们docker服务搭建发布已经完成。
