跟乐乐学Docker容器!
一.认识Docker
什么是Docker‘容器’？
Docker是一种容器,准确来说是一个应用容器引擎，比如一个centos服务器系统，当前的生产环境是jdk8,mysql5.1,nginx5，那么我们可以通过Docker把当前系统‘拷贝’，然后‘粘贴’在centos服务器上通过简单的操作就能部署完全相同的环境。
而这之间的’拷贝‘和’粘贴‘，就需要Dokcer这种容器来实现。
Docker用来做什么？
比如说，程序员A和程序员B分别要在不同的服务器上部署同一个项目。
但是程序员A的服务器是jdk8,mysql5.1，程序员B的服务器是jdk9，mysql5.5
那么当程序员A把项目文件发给程序员B，程序员B部署时却出现了错误，原因就是服务器环境差异所造成的一种bug等等，比如数据库版本不匹配啊，jdk版本不匹配啊等等。
同样的案例数不胜数，相信大家也都遇到过，一个项目在朋友的电脑上能跑起来，在自己的电脑上却跑不起来，原因又找不到的问题。
所以这个时候呢，就需要docker这个东西来把程序员A的服务器环境在docker容器里头实现，然后再把它拿到程序员b所在的服务器进行部署，使两个程序员的服务器环境完全一致，就可以解决这个问题了。
二.安装Docker
服务器环境
Docker可以运行在Windows,Mac,CentOS,Ubuntu操作系统上，这里我的演示是基于CentOS系统的VPS服务器来演示。
服务器性质：vps 新加坡节点 OpenVZ架构
服务器运营商：https://my.webhorizon.in/
服务器版本：CentOS-7-x86_64-minimal
Docker版本：17.03 CE社区版

5、 查看docker版本，验证是否验证成功
docker -v
[root@abc906093117 ~]# docker -v
Docker version 20.10.7, build f0df350
三.配置Docker
配置Docker镜像加速器
Docker默认会从官方的’Docker hub’仓库来下载Docker镜像,仓库的地址为https://hub.docker.com/。
但很显然，在国内下载官方仓库中的Dokcer镜像是非常慢的，因此需要配置Docker镜像加速器，有如下几种：
- USTC 中科大镜像加速器：https://docker.mirrors.ustc.edu.cn
- 阿里云镜像加速：需要到阿里云控制台配置
如果你用USTC，那么过程会比较简单。我使用的是阿里云镜像加速，但需要自己到阿里云控制台进行配置。
首先登陆阿里云，进入控制台，搜索’镜像’，选择‘容器镜像服务’
选择左侧工具栏中的‘镜像加速器’。
在这里我们可以看到，阿里云为我们提供的个人镜像加速地址。
同时，页面中有对应各个不同操作系统的配置方法，这里我选择CentOS系统，直接将红框内的命令复制到ssh控制台执行即可。
[root@abc906093117 ~]# sudo mkdir -p /etc/docker
[root@abc906093117 ~]# sudo tee /etc/docker/daemon.json <<-'EOF'
> {
> "registry-mirrors": ["https://tj3iost4.mirror.aliyuncs.com"]
> }
> EOF
{
"registry-mirrors": ["https://tj3iost4.mirror.aliyuncs.com"]
}
[root@abc906093117 ~]# sudo systemctl daemon-reload
[root@abc906093117 ~]# sudo systemctl restart docker
看一看Docker加速镜像中的配置文件是否已经成功更改为阿里云提供的个人镜像加速地址。
cat /etc/docker/daemon.json
[root@abc906093117 ~]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://tj3iost4.mirror.aliyuncs.com"]
}
[root@abc906093117 ~]#
这里呢，可以看到配置文件中已经写入了之前阿里云为我们提供的个人镜像加速地址。
四.使用Docker
一.【命令】Docker服务的启动与停止和状态
启动：systemctl start docker
停止：systemctl stop docker
重启：systemctl restart docker
查看状态：systemctl status docker
开启开机自动启动：systemctl enable docker
查看帮助文档：docker --help
查看概要信息：docker info 该命令可以查看docker的官方镜像仓库和私人镜像仓库的地址，以及版本等信息。
二.【命令】镜像操作
1.查看本地（已存在的）镜像
docker images
[root@abc906093117 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
REPOSITORY 是镜像名称
TAG 是标签，多用来镜像版本区分
IMAGE ID 是镜像id，它是唯一的。
CREATED 是该镜像创建至今的时间。
SIZE 是镜像大小，单位为mb。
2.搜索镜像
注意，这是从仓库中搜索镜像，而不是本地。
同时这是一个模糊搜索，将列出所有包括该字符串的镜像。
docker search 镜像名称
[root@abc906093117 ~]# docker search nginx

5.删除所有镜像
docker rmi ‘docker images -q’
三.【命令】容器操作
容器是基于镜像去运行的，一个镜像可以创建多个容器。关系类似就类似于java中的类与对象。
一.创建容器
docker run -参数名1 -参数名2 -参数名n --name=自定义容器名 镜像名称:镜像标签
[root@abc906093117 ~]# docker images （先查看已经拉取的镜像有哪些）
REPOSITORY TAG IMAGE ID CREATED SIZE
linuxserver/nginx latest befde9691ea1 6 days ago 166MB
[root@abc906093117 ~]# docker run -id --name=myNginxDocker linuxserver/nginx:latest （-i表示创建容器。-d代表后台守护式运行，不进入到这个容器的终端。镜像标签名为latest的话可以省略，此处我没省略)
4c7c6eeef68d352725bc8c6133284c550b1122b5e8b268eaa732dd40c277d0c9
[root@abc906093117 ~]# docker ps (查看当前正在运行的镜像)
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4c7c6eeef68d linuxserver/nginx:latest "/init" 5 seconds ago Up 4 seconds 80/tcp, 443/tcp myNginxDocker
Docker的创建容器命令是’docker run‘配合一些参数来实现的，下面来介绍一下参数。
1 关于参数i和t的解释：
参数 -i :表示创建容器
参数 -t:表示容器启动后就进入该容器的命令行操作处，即分配一个伪终端，在这个伪终端里可以和容器外的宿主机一样进行命令操作。
当参数为’-it’时，则表示创建容器后立马进入该容器所分配的伪终端命令行。
2 容器命名参数：–name
为所创建的容器命名，如 --name=myNginxDocker
3 目录映射参数：-v
将容器的某个目录和宿主机的某个目录进行映射，形成一个映射关系。这类似于为VM虚拟机和宿主机之间所设置的共享文件夹。
4 守护式创建容器:-d
如果加上-d参数的话，则会创建一个守护式容器从而在后台运行。但这样创建后就不会自动进入容器的伪终端。
也就是说，如果不仅有-i，-t这两个参数，还有-d的话，并不会在创建容器后自动登录进入到伪终端。
5 端口映射：-p
用于容器和宿主机之间的端口映射，前者是宿主机端口，后者是容器内端口。可以使用多个-p来做多个端口的映射。
二.查看当前在运行状态的容器
docker ps
[root@abc906093117 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4c7c6eeef68d linuxserver/nginx:latest "/init" 5 seconds ago Up 4 seconds 80/tcp, 443/tcp myNginxDocker
三.查看当前包括非运行状态在内的容器
docker ps -a
[root@abc906093117 ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4c7c6eeef68d linuxserver/nginx:latest "/init" 13 minutes ago Up 13 minutes 80/tcp, 443/tcp myNginxDocker
四.进入或退出运行状态容器的伪终端
进入：docker exec -it 运行中的容器名 bash
退出（在伪终端内）：exit
[root@abc906093117 ~]# docker exec -it myNginxDocker bash (如果镜像本身不支持伪终端，需要末尾加上bash才能显示伪终端）
root@4f45c0429061:/# exit (此时已经进入到了伪终端，输入exit退出）
exit
[root@abc906093117 ~]#
关于进入：
我们创建容器后，容器也的的确确在运行。但是，你也可以进入容器的伪终端来进行操作。需要注意的是，个别镜像本身是不支持伪终端的，如nginx镜像，因为它本身就是个应用，进入容器之后只能看到日志的输出，需要末尾加上bash才能显示伪终端。
但如果你的镜像是centos这类的话，那么进入该容器后是能够直接以终端形式来操作的。
关于退出：
如果你的容器不是以后台守护创建运行的话，那么执行exit退出伪终端将会直接停止运行该容器。
五.停止容器运行
docker stop 容器名/容器id
[root@abc906093117 ~]# docker stop myNginxDocker
myNginxDocker
六.启动容器
docker start 容器名/容器id
[root@abc906093117 ~]# docker start myNginxDocker
myNginxDocker
七.删除容器
docker rm 容器名/容器id
[root@abc906093117 ~]# docker rm myNginxDocker
myNginxDocker
八.文件拷贝
OR.从宿主机拷贝文件到容器中
docker cp 需要拷贝的文件或文件夹 容器名称/容器id:容器目录
[root@abc906093117 ~]# cat > test.txt (现在宿主机当前的目录下创建一个'test.txt'文件)
textFileForDockerFileCopyTest
[root@abc906093117 ~]# dir (搜索下当前目录是否存在创建的文件)
test.txt
[root@abc906093117 ~]# docker cp test.txt myNginxDocker:/ (这里拷贝文件到容器中，‘/'是我所指定的、该容器的目录。当前宿主机命令行是在'root'目录，而'text.txt'文件也是在root目录下，所以不需要指定绝对路径)
[root@abc906093117 ~]# docker exec -it myNginxDocker bash (进入到容器终端)
root@83e0c8d4cc31:/# dir (查看当前目录下的文件有哪些)
app config dev etc init libexec mnt proc run srv test.txt usr
bin defaults docker-mods home lib media opt root sbin sys tmp var
root@83e0c8d4cc31:/# cat test.txt (打开看一下)
textFileForDockerFileCopyTest
OR.从容器拷贝文件到宿主机中
*docker cp 容器名称/容器id:文件或目录的绝对路径 拷贝到宿主机后的文件名
root@83e0c8d4cc31:/# cat > testFile.txt (在容器中创建文件'testFile.txt')
testDockerCopyForLocalServer
root@83e0c8d4cc31:/# dir (看下当前目录存不存在它)
app config dev etc init libexec mnt proc run srv testFile.txt usr
bin defaults docker-mods home lib media opt root sbin sys tmp var
root@83e0c8d4cc31:/# exit (退出容器的伪终端，返回到宿主机)
exit
[root@abc906093117 ~]# docker cp myNginxDocker:/testFile.txt test.txt (从容器’myNginxDocker'拷贝文件，绝对路径为'/testFile.txt' ，文件拷贝到宿主机后命名为'test.txt'
[root@abc906093117 ~]# dir
test.txt
[root@abc906093117 ~]# cat test.txt (查看一下文件内容，拷贝成功)
testDockerCopyForLocalServer
九.目录映射挂载
关于目录映射挂载，前面已经说过了，就是指定一个容器的目录和一个宿主机的目录进行映射，类似共享文件夹。
需要注意的是，目录挂载映射只能在创建容器时指定，对于已经创建后的容器无法指定。
如果你的要映射的目录是多级的，可能会提示你权限不足。这是因为centos系统中安全模块‘selinux’把权限禁掉了。需要添加参数–privileged=true
docker run -参数名1 -参数名2 -参数名n -v 宿主机目录绝对路径:容器目录绝对路径 --name=自定义容器名 镜像名称:镜像标签
[root@abc906093117 ~]# docker rm myNginxDocker （先删除此前创建的容器）
myNginxDocker
[root@abc906093117 ~]# mkdir myDirectory (在当前文件夹创建myDirectory文件夹，这个文件夹将被用到后面的目录映射中。）
[root@abc906093117 ~]# cd myDirectory （进入该目录）
[root@abc906093117 myDirectory]# cat > directoryMappingFile.txt （在该目录下再创建一个文本用于测试）
directoryMappingFileTextForTest
[root@abc906093117 myDirectory]# cd ../ （返回到上级目录）
[root@abc906093117 ~]# pwd （查看当前所在目录的路径）
/root
[root@abc906093117 ~]# docker images （查看所有本地的镜像，用于创建容器）
REPOSITORY TAG IMAGE ID CREATED SIZE
linuxserver/nginx latest befde9691ea1 8 days ago 166MB
[root@abc906093117 ~]# docker run -i -d -v /root/myDirectory:/directoryMappingTest --name=myNginxDocker linuxserver/nginx:latest （以后台守护方式创建容器‘myNginxDocker’，镜像为‘linuxserver/nginx’，指定宿主机目录‘/root/myDirectory’同容器目录‘/directoryMappingTest’进行映射，如果容器不存在这个目录会自动创建）
1f9649eaf496d40cc36ab0c41562bac848ee228a2b3d91fde3b9f004107c3d39
[root@abc906093117 ~]# docker exec -it myNginxDocker bash （进入容器伪终端)
root@1f9649eaf496:/# cd directoryMappingTest (进入尝试进入映射目录）
root@1f9649eaf496:/directoryMappingTest# cat directoryMappingFile.txt （进入成功，尝试查看该映射目录下的文本文件）
directoryMappingFileTextForTest
## 接下来，我们试试添加 --privileged=true 来创建容器。
root@1f9649eaf496:/directoryMappingTest# exit
exit
[root@abc906093117 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1f9649eaf496 linuxserver/nginx:latest "/init" 20 minutes ago Up 20 minutes 80/tcp, 443/tcp myNginxDocker
[root@abc906093117 ~]# docker run -i -d --privileged=true -v /root/myDirectory:/directoryMappingTest --name=myNginxDockerTwo linuxserver/nginx:latest （通过--privileged=true参数来创建容器，可以解决多级目录映射时权限不足的问题）
775b6dbf16a566a06b8c423d45d2c9c609647f554933c15583fda3d8848f5d20
[root@abc906093117 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
775b6dbf16a5 linuxserver/nginx:latest "/init" 7 seconds ago Up 5 seconds 80/tcp, 443/tcp myNginxDockerTwo
1f9649eaf496 linuxserver/nginx:latest "/init" 21 minutes ago Up 21 minutes 80/tcp, 443/tcp myNginxDocker
[root@abc906093117 ~]#
十.查看容器详细信息（包括IP）
查看容器信息，会列出包括容器ip在内的所以详细信息：
docker inspect 容器名称或容器id
仅仅查看容器ip:
docker inspect --format=’{{.NetworkSettings.IPAddress}}’ 容器名称或容器id
[root@abc906093117 ~]# docker inspect myNginxDocker （查看容器’myNginxDocker‘的全部信息）

718c6b9ad5fdf03dfbd497fd507e89104345c63b4baf0500daa186e7b9b6dd05
参数解释：
-i创建容器-d以后台守护式创建-p将容器端口和宿主机端口进行映射，左边为宿主机端口,右边为容器中mysql的端口-e表示添加环境变量，MYSQL_ROOT_PASSWORD这个变量用于设定mysql的root权限密码。--name用于给容器起个名。
第四步，查看状态
可以看到在’PORTS‘这一栏，有显示端口映射信息。
[root@abc906093117 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

第五步，尝试进入伪终端
[root@abc906093117 ~]# docker exec -it myMysqlDocker bash
bash-4.2$
第六步，尝试在本机连接在VPS的Docker容器中建立的Mysql数据库。
可以看到，连接成功了！

Status: Downloaded newer image for tomcat:latest
docker.io/library/tomcat:latest
三，创建Tomcat容器
docker run -id -v /root/tomcatDockerFile:/usr/locat/tomcat/webapps -p 8081:8080 --name=myTomcatDocker tomcat:latest
[root@abc906093117 ~]# docker images

[root@abc906093117 ~]# docker run -id -v /root/tomcatDockerFile:/usr/locat/tomcat/webapps -p 8081:8080 --name=myTomcatDocker tomcat:latest
859c39421a3b92dbab1bcd7fce8a1d757d4c705106e8c967bfb82cb79c81ffce
参数解释：
-i创建容器-d以后台守护式创建-p将容器端口和宿主机端口进行映射，左边为宿主机端口,右边为容器中tomcat的端口-v目录映射，左边为宿主机目录，右边为tomcat容器目录。需要注意的是，/usr/locat/tomcat/webapps目录本身在tomcat容器里是已经存在的，因此将来我们部署项目时，就可以直接在宿主机来把项目war包放在tomcat的webapps目录下。--name用于给容器起个名。
四. 使用自己电脑访问tomcat
Nginx部署
一.搜索Nginx镜像
[root@abc906093117 ~]# docker search nginx

Status: Downloaded newer image for nginx:latest
docker.io/library/nginx:latest
三.创建Nginx容器
docker run -i -d -p 81:80 --name=myNginxDocker nginx:latest
[root@abc906093117 ~]# docker run -i -d -p 81:80 --name=myNginxDocker nginx:latest
bc5517dcdad940d885808cda468c93c5e234a7649562aa3a94ca15f9aadc8f52
参数解释：
-i创建容器-d以后台守护式创建-p将容器端口和宿主机端口进行映射，左边为宿主机端口,右边为容器中nginx的端口--name用于给容器起个名。
四.关于nginx配置相关。
我们部署项目，肯定是需要将资源和ngxin.conf配置文件放到容器里头的。
那么这就需要我们进入容器里头，来查看一下这个nginx容器的目录结构了。
通过docker exec 命令进入到nginx容器后，我们访问/etc目录，然后通过dir命令，就能列出etc当前的目录有哪些，其中有nginx目录
[root@abc906093117 ~]# docker exec -i -t myNginxDocker bash
root@bc5517dcdad9:/# cd /etc
root@bc5517dcdad9:/etc# dir
adduser.conf debconf.conf gai.conf hosts ld.so.conf.d motd passwd rc4.d selinux systemd
alternatives debian_version group init.d ldap mtab passwd- rc5.d shadow terminfo
apt default group- inputrc libaudit.conf nginx profile rc6.d shadow- timezone
bash.bashrc deluser.conf gshadow issue localtime nsswitch.conf profile.d rcS.d shells ucf.conf
bindresvport.blacklist dpkg gshadow- issue.net login.defs opt rc0.d resolv.conf skel update-motd.d
ca-certificates environment gss kernel logrotate.d os-release rc1.d rmt ssl xattr.conf
ca-certificates.conf fonts host.conf ld.so.cache machine-id pam.conf rc2.d securetty subgid
cron.daily fstab hostname ld.so.conf mke2fs.conf pam.d rc3.d security subuid
我们再进入这个nginx目录，再通过dir命令查看，就发现了一个让我们熟悉的文件，没错，就是nginx的配置文件‘nginx.conf’。
root@bc5517dcdad9:/etc# cd nginx
root@bc5517dcdad9:/etc/nginx# dir
conf.d fastcgi_params mime.types modules nginx.conf scgi_params uwsgi_params
打开nginx.conf看一下
root@bc5517dcdad9:/etc/nginx# cat nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
但是，如果一个个在容器里头配，不是很麻烦吗？所以这里建议大家在创建容器时指定好映射目录。或者是通过docker cp命令来拷贝.
这里顺便补充一下，nginx的配置路径大致是下面三个：
- /etc/nginx/nginx.conf 这个是文件路径
- /var/log/nginx 这个是log目录路径
- /usr/share/nginx/html 这个是静态资源文件路径
五.使用自己电脑访问Nginx
Redis部署
一.搜索Redis镜像
[root@abc906093117 ~]# docker search redis

二.拉取镜像’redis’
[root@abc906093117 ~]# docker pull redis
Using default tag: latest
latest: Pulling from library/redis
b4d181a07f80: Already exists
86e428f79bcb: Pull complete

Status: Downloaded newer image for redis:latest
docker.io/library/redis:latest
三.创建容器
docker run -i -d -p 6380:6379 --name=myRedisDocker redis:latest
[root@abc906093117 ~]# docker run -i -d -p 6380:6379 --name=myRedisDocker redis:latest
074e6d3c2e46ab4a266fd4c1bdff3581e1816d6ec955ab4264aad0f243268749
参数解释：
-i创建容器-d以后台守护式创建-p将容器端口和宿主机端口进行映射，左边为宿主机端口,右边为容器中redis的端口--name用于给容器起个名。
四.用自己电脑的Redis客户端进行访问
访问成功！
六.容器备份与迁移
一.将容器保存为镜像
注意：镜像名称必须为小写。
docker commit 已存在的容器名 自定义镜像名
[root@abc906093117 ~]# docker ps -a （查看已经创建了的容器）
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1388723764b0 nginx:latest "/docker-entrypoint.…" 20 seconds ago Up 13 seconds 0.0.0.0:81->80/tcp, :::81->80/tcp myNginxDocker
[root@abc906093117 ~]# docker commit myNginxDocker nginximage （将名为'myNginxDocker'的容器保存为镜像，镜像命名为‘nginximage‘）
sha256:2373291d219fe01c1efd943876c7418865256b3ceb3cafe4115c7aca413282ad
[root@abc906093117 ~]# docker images （再查看本地镜像，发现之前保存的镜像’nginximage‘是已经在本地了的）
REPOSITORY TAG IMAGE ID CREATED SIZE
nginximage latest 2373291d219f 2 minutes ago 133MB
nginx latest 4f380adfc10f 11 days ago 133MB
二.镜像备份（打包为tar文件）
我们可以将镜像进行备份，也就是打包为tar压缩文件。这样方便我们将该镜像部署在其它服务器。
这里我就以之前的’nginximage‘镜像为例子。
docker save -o 自定义tar文件名.tar 要被备份的镜像名
[root@abc906093117 ~]# docker save -o nginxImageBackup.tar nginximage （将镜像’nginximage‘备份打包为tar压缩文件，命名为’nginxImageBackup.tar‘）
[root@abc906093117 ~]# ll （查看是否备份成功，可以看到已经存在）
total 134184
-rw------- 1 root root 137402880 Jul 4 16:59 nginxImageBackup.tar
三.镜像还原
当你把已经备份好了、打包为tar压缩文件的镜像迁移到另一个服务器后，你需要将该tar压缩文件还原为镜像才能使用，这个步骤叫做镜像还原。
*docker load -i 要被还原的镜像tar压缩包文件名 *
[root@abc906093117 ~]# docker ps （查看运行中的容器）
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1388723764b0 nginx:latest "/docker-entrypoint.…" 15 minutes ago Up 15 minutes 0.0.0.0:81->80/tcp, :::81->80/tcp myNginxDocker

七.Dockerfile
DockerFile是什么?(重要)
首先我们需要知道什么是基础镜像和最终镜像。
所谓基础镜像，比如我拉取一个ElasticSearch镜像，
但是ElasticSearch是基于Jdk来运行的，所以这个ES镜像必定是基于Jdk镜像的基础上来实现的。
因此，此处jdk镜像相对于ES镜像就是基础镜像；es镜像相对于jdk镜像则是最终镜像。
又比如，我们后期需要在这个ElasticSearch镜像上装上了一个微服务项目去跑，并构建成为了一个新的镜像
那么这个镜像相对于ES镜像就是最终镜像，es镜像则成为了基础镜像。
Dockerfile是由一系列命令和参数所构成的脚本，这些命令和参数将应用于一个基础镜像，并最终创建为一个新的镜像。
常用命令
常用命令如下：
| 命令 | 详解 |
|---|---|
| FROM 镜像名称:镜像标签 | 表示定义通过哪个基础镜像来进行构建，如果本地不存在该镜像，则进行拉取 |
| MAINTAINER 姓名 | 用来声明镜像的创建者，可省略。 |
| ENV 环境变量键名 环境变量数值 | 声明环境的变量，可声明多个 。单次定义单个变量时，格式为ENV KEY VALUE/例如：ENV JAVA_HOME /usr/local/java/jdk1.8.0_291 单次定义多个变量时，格式为env key1=value1 key2=value2 例如：ENV JAVA_HOME=/usr/local/jdk/jdk1.8.0_291 JRE_HOME=/usr/local/jdk/jdk1.8.0_291/jre |
| Run linux命令 | 用于执行系统命令，同样可以执行多个，使用‘&&’表示命令分割。注意：每使用一次RUN命令，都会在叠加一层镜像，造成体积过大。因此尽量使用单个RUN命令，来执行多个linux命令避免镜像叠加。例如:RUN yum install wget && wget -O redis.tar.gz “http://download.redis.io/releases/redis-5.0.3.tar.gz” && tar -xvf redis.tar.gz |
| ADD 宿主机文件或目录路径 容器路径 | 将宿主机的文件或目录拷贝到容器内，如果有压缩文件将会自动解压 |
| COPY 宿主机文件或目录路径 容器路径 | 和ADD类似， 将宿主机的文件拷贝到容器内，但即使是存在压缩包文件也不会对其解压。 |
| WORKDIR 目录路径 | 一:设置Dockerfile的工作目录，表示当前DockerFile执行的所有命令，都是在当前目录下所执行的，比如我使用’RUN wget www.ssol.cn/tools.sh’命令拉取一个文件，那么这个文件默认是保存在该目录下的。二:登陆容器伪终端后的所在目录，也将是这个目录。 |
尝试：基于CentOS7基础镜像构建Springboot项目镜像
该项目准确来说是一个爬虫小demo。
所使用的数据库为mysql.
所以我们大致明白，在基于这个centos7镜像的基础上，我们需要分别构建jdk1.8,mysql,nginx这三个。至于为什么不需要tomcat，是因为该项目是基于springboot的jar包方式打包，内部已经集成了tomcat。
（你也可以指定打包方式为war包来配合外部tomcat来部署，但我觉得麻烦，就直接用jar打包了。）
一：上传jdk,mysql,nginx
jdk使用的是：jdk-8u291-linux-x64.tar.gz
mysql使用的是：MySQL-5.6.22-1.el6.i686.rpm-bundle.tar
nginx使用的是：nginx-1.8.0.tar.gz
先使用rz，将jdk和mysql以及nginx上传到宿主机
（rz的使用：https://www.cnblogs.com/nbf-156cwl/p/8641165.html）
[root@ljy ~]# rz -y
[root@abc906093117 ~]# ll (查看是否上传到宿主机)

-rw-r--r-- 1 root root 10494431 May 18 15:40 rabbitmq-server-3.7.18-1.el7.noarch.rpm
[root@abc906093117 ~]# mkdir -p /usr/local/dockerSpringBootProject (创建一个目录，该目录用于jdk相关的存放)
[root@abc906093117 ~]# mv jdk-8u291-linux-x64.tar.gz /usr/local/dockerSpringBootProject && mv MySQL-5.6.22-1.el6.i686.rpm-bundle.tar.gz /usr/local/dockerSpringBootProject && mv nginx-1.8.0.tar.gz /usr/local/dockerSpringBootProject (将上传了的jdk，nginx，mysql文件移动到该目录)
[root@abc906093117 ~]# cd /usr/local/dockerSpringBootProject (进入该目录)
[root@abc906093117 dockerjdk]# vi Dockerfile (创建dockerfile脚本文件，名称必须起名为‘Dockerfile'，不然无法使用Dockerfile，注意首字母大写。)
二：编写dockerfile脚本
Dockerfile脚本内容如下：
FROM centos:7
MAINTAINER lele
WORKDIR /usr
# 创建环境目录，并分别安装jdk，mysql和nginx得相关依赖库。
RUN mkdir /usr/local/jdk && mkdir /usr/local/mysql && mkdir /usr/local/nginx \
&& yum update -y && yum install -y gcc-c++ && yum install -y glibc.i686 \
&& yum install -y libaio.so.1 libgcc_s.so.1 libstdc++.so.6 && yum repolist -y && yum install -y libstdc++-4.8.5-44.el7.i686 \
&& yum update -y libstdc++-4.8.5-44.el7.i686 && yum install -y libncurses.so.5 libtinfo.so.5 \
&& yum install -y pcre pcre-devel && yum install -y zlib zlib-devel && yum install -y openssl openssl-devel
# 将脚本文件所在目录下的jdk,mysql,nginx压缩包拷贝到容器，并自动解压
ADD jdk-8u291-linux-x64.tar.gz /usr/local/jdk
ADD MySQL-5.6.22-1.el6.i686.rpm-bundle.tar.gz /usr/local/mysql
ADD nginx-1.8.0.tar.gz /usr/local/mysql
# 设置jdk环境变量
ENV JAVA_HOME=/usr/local/jdk/jdk1.8.0_291 JRE_HOME=$JAVA_HOME/jre CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib PATH=$JAVA_HOME/bin:$PATH
脚本编辑完毕后，按’:'后输入wq并按回车进行保存.
此步骤的Dockerfile语法可以参考：
https://www.runoob.com/docker/docker-dockerfile.html
https://blog.csdn.net/weixin_39393393/article/details/116298849

三：开始构建镜像（目前安装还会出错。。）
构建命令格式为：
docker build -t 全为小写的自定义镜像名 .
例如：
docker build -t springbootproject .
其中’.‘表示指定使用当前目录下的dockerfile脚本进行构建，当然，前提是当前目录下有一个名叫’Dockerfile’的脚本文件。
构建过程如下：
[root@abc906093117 dockerSpringBootProject]# docker build -t springbootproject .
Sending build context to Docker daemon 359.4MB

注意：
如果你用到了Dockerfile的Run命令语法来执行的多个或单个linux命令的话，需要保证每个linux命令在执行时都不会出错；否则Dockerfile构建镜像会失败，失败后触发事务，不存在这个镜像。
