二、基础容器篇

# 三、容器篇

## 1、基本容器命令

说明：有了镜像才可以创建容器。

实验前准备：下载一个最新的centos的镜像，当前最新的是centos8.x

```
[root@localhost ~]# docker pull centos
Using default tag: latest
latest: Pulling from library/centos
a1d0c7532777: Pull complete
Digest: sha256:a27fd8080b517143cbbbab9dfb7c8571c40d67d534bbdee55bd6c473f432b177
Status: Downloaded newer image for centos:latest
docker.io/library/centos:latest
```

### 1.1、docker run #启动镜像

#### （1）常用参数说明

```
--name    #为容器分配一个名称
--detach，-d    #在后台运行容器并打印容器ID
--interactive，-i    #即使未连接STDIN，也应使其保持打开状态，    #-it 使用交互方式运行，进入容器查看内容
--tty，-t    #分配伪TTY
--publish，-p    #将容器的端口发布到主机，指定容器端口（小p）
    -p    #ip：主机端口：容器端口
    -p    #主机端口：容器端口（常用）
    -p    #容器端口
--publish-all，-P    #将所有公开的端口发布到随机端口，随机指定端口（大P）
```

#### （2）使用交互方式进入容器，并退出

```
[root@localhost ~]# docker run -it centos /bin/bash    #使用bash命令
[root@0fdfd540855e /]# ls    #查看容器内的centos，基础版本，很多命令不完善
bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
[root@0fdfd540855e /]# pwd
/
[root@0fdfd540855e /]# exit    #停止运行并退出，使用快捷键ctrl+p+q，容器运行并退出
exit
```

### 1.2、docker ps #显示所有正在运行的容器

#### （1）常用参数

```
-a    #列出当前正在运行的容器+历史运行的容器
-n=？    #显示最近创建的容器，后面跟个数
-q     #只显示容器的编号
```

#### （2）操作示例

```
[root@localhost ~]# docker ps    
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
[root@localhost ~]# docker ps -a    #显示正在运行过的容器+历史运行的容器
CONTAINER ID   IMAGE          COMMAND       CREATED         STATUS                     PORTS     NAMES
0fdfd540855e   centos         "/bin/bash"   3 minutes ago   Exited (0) 2 minutes ago             compassionate_shirley
36ad1e1372aa   9c7a54a9a43c   "/hello"      24 hours ago    Exited (0) 24 hours ago              epic_franklin
[root@localhost ~]# docker ps -a -n=1    #显示当前正在运行的一个容器
CONTAINER ID   IMAGE     COMMAND       CREATED         STATUS                     PORTS     NAMES
0fdfd540855e   centos    "/bin/bash"   8 minutes ago   Exited (0) 6 minutes ago             compassionate_shirley
[root@localhost ~]# docker ps -aq    #显示所有运行的容器的编号
0fdfd540855e
36ad1e1372aa

#启动容器，并运行退出
[root@localhost ~]# docker run -it centos /bin/bash
[root@6fa211a6ad77 /]# [root@localhost ~]#    #使用快捷键ctrl+p+q，容器运行并退出
[root@localhost ~]# docker ps
CONTAINER ID   IMAGE     COMMAND       CREATED          STATUS          PORTS     NAMES
6fa211a6ad77   centos    "/bin/bash"   18 seconds ago   Up 18 seconds             practical_ganguly

```

### 1.3、dcoker rm #删除镜像

```
docker rm 容器ID    #删除指定容器，不能删除正在运行的容器，强制删除加-f参数
docker rm -f $(docker ps -qa)    #删除所有容器
docker ps -a -q|xargs docker rm    #删除所有容器
```

### 1.4、启动和停止容器

```
docker start 容器ID        #启动容器
docker restart 容器ID        #重启容器
docker stop 容器ID        #停止容器
docker kill 容器ID        #强制停止当前容器

[root@localhost ~]# docker ps    #查看正在运行的容器，当下有一个正在运行的容器
CONTAINER ID   IMAGE     COMMAND       CREATED         STATUS         PORTS     NAMES
6fa211a6ad77   centos    "/bin/bash"   9 minutes ago   Up 9 minutes             practical_ganguly
[root@localhost ~]# docker stop 6fa211a6ad77    #停止正在运行编号为6fa211a6ad77的容器
6fa211a6ad77
[root@localhost ~]# docker ps    #查看正在运行的容器，当下为空
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
[root@localhost ~]# docker start 6fa211a6ad77    #启动编号为6fa211a6ad77的容器
6fa211a6ad77
[root@localhost ~]# docker ps    #查看正在运行的容器
CONTAINER ID   IMAGE     COMMAND       CREATED          STATUS         PORTS     NAMES
6fa211a6ad77   centos    "/bin/bash"   10 minutes ago   Up 3 seconds             practical_ganguly

[root@localhost ~]# docker kill  6fa211a6ad77    #杀掉正在运行编号为6fa211a6ad77的容器
6fa211a6ad77
```

### 1.5、后台启动容器

```
# 命令 docker run -d 镜像名
[root@kuangshen /]# docker run -d centos
# 问题docker ps，发现 centos 停止了
# 常见的坑:docker 容器使用后台运行，就必须要有要一个前台进程，doker发现没有应用，就会自动停止
# 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
```

### 1.6、查看日志

```
docker logs -tf --tail {number} 容器ID或名称

# 编写一段脚本测试日志
[root@localhost ~]# docker run -d centos /bin/bash -c "while true;do echo 1111111;sleep 1;done"    #一直重复打印10
731862fc784fe25f293a005100d0a9aa5a83531a77dfbec637a6017b127a81be
[root@localhost ~]# docker ps
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS     NAMES
731862fc784f   centos    "/bin/bash -c 'while…"   5 seconds ago   Up 4 seconds             angry_clarke

#显示日志
 -tf    显示所以日志
 --tail {number}    显示日志条数
[root@localhost ~]# docker logs -tf --tail 10 731862fc784f    #查看容器日志

### 1.7、查看容器中的进程信息

```
# docker top 容器ID
[root@localhost ~]# docker top 731862fc784f
UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD
root                41246               41227               0                   15:14               ?                   00:00:00            /bin/bash -c while true;do echo 1111111;sleep 1;done
```

### 1.8、查看镜像的元素据（所有信息）

```

### 1.9、宿主机与容器之间的文件拷贝

```
#命令 docker cp 容器ID:容器内路径        目的主机路径            #反之一样
#测试，宿主机拷贝文件至容器
[root@localhost ~]# docker run -d -it centos /bin/bash
3c5874f6363fcb8aa8fcb7a973cd0c71c7568a7d6eba125b9af0df9db3509e88
[root@localhost ~]# docker ps
CONTAINER ID   IMAGE     COMMAND       CREATED         STATUS         PORTS     NAMES
3c5874f6363f   centos    "/bin/bash"   7 seconds ago   Up 5 seconds             cranky_swartz
[root@localhost ~]# echo ceshi > 1.txt
[root@localhost ~]# docker cp 1.txt 3c5874f6363f:/root/1.txt
Successfully copied 2.05kB to 3c5874f6363f:/root/1.txt
[root@localhost ~]# docker exec -it 3c5874f6363f bash
[root@3c5874f6363f /]# cat /root/1.txt
ceshi
[root@3c5874f6363f /]#
```

## 2、commit提交一个自己的镜像

```
docker commit 提交容器成为一个新的副本，类似虚拟机的快照
# 命令和git原理类似
docker commit -m "提交秒速信息" -a="作者" 容器ID  目标镜像名，[TAG]
```

### 2.1、提交一个自己修改过后的tomcat镜像

官方默认的版本是没有webapps的，自己添加文件进去

#### 2.1.1、查询tomcat镜像

```

#### 2.1.2、下载Tomcat最新镜像

```
[root@localhost ~]# docker pull tomcat
Using default tag: latest
latest: Pulling from library/tomcat

Status: Downloaded newer image for tomcat:latest
docker.io/library/tomcat:latest
```

#### 2.1.3、创建一个容器并启动

```
root@localhost ~]# docker run --name tomcat01 -d -p 80:8080 tomcat
0e031df6bcf990257475f0403eff57ca59fb6d175b5d1c229a5869e2f38197e2
[root@localhost ~]# docker ps
CONTAINER ID   IMAGE                 COMMAND             CREATED         STATUS         PORTS                                       NAMES
0e031df6bcf9   tomcat                "catalina.sh run"   6 seconds ago   Up 5 seconds   0.0.0.0:80->8080/tcp, :::80->8080/tcp       tomcat01

[root@localhost ~]#
```

#### 2.1.4、测试，测试机访问地址：http://ip:80

![](/media/202309/image-20230808155636964.png)

出现问题404，因为官方默认的Tomcat做了精简，webapps下没有文件，我们将webapps.dist下文件拷贝致webapps下

```
[root@localhost ~]# docker exec -it tomcat01 bash
root@0e031df6bcf9:/usr/local/tomcat# cp -r webapps.dist/* webapps
```

再次测试，测试结果正常，tomcat版本为10.0.14

#### 2.1.5、将修改后的容器通过commit提交，方便下次自己使用

```
[root@localhost ~]# docker commit -a="zxw" -m="add webapps app" 0e031df6bcf9 tomcat_01:1.0
sha256:452d84ab3a010a1b17f5f39c575aa5cabcd6e384d4d421524ac2be0dedd46e7b

```

------

### 2.2.提交一个安装好nginx+php的镜像

> 本次采用rpm二进制包安装，nginx版本为1.24.0，php版本为8.0

#### 2.2.1.启动一个基础的centos7镜像

```shell
[root@localhost ~]# docker run -itd --name nginx_php --privileged=true  centos:centos7.9.2009   /usr/sbin/init
```

#默认容器是普通用户权限，使用--privileged=true 将容器运行权限调整为特权，方便后续一些命令的执行

#### 2.2.2.将宿主机提前准保好的yum文件复制到容器中

```shell
[root@localhost ~]# docker cp Centos-7.repo nginx_php:/etc/yum.repos.d/.
Successfully copied 4.1kB to nginx_php:/etc/yum.repos.d/.
```

#### 2.2.3.进入容器安装相关工具，配置清华站点php的yum源，下载nginx二进制包

```shell
[root@cf4a8afce6a4 /]# rm -rf /etc/yum.repos.d/CentOS-*
[root@cf4a8afce6a4 /]# yum install wget vim -y
[root@cf4a8afce6a4 /]# yum -y install https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/remi-release-7.rpm
[root@cf4a8afce6a4 /]# yum -y install yum-utils
[root@cf4a8afce6a4 /]# wget https://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.24.0-1.el7.ngx.x86_64.rpm
```

#### 2.2.4.查看可使用的php版本yum信息

```shell
[root@cf4a8afce6a4 /]# ll /etc/yum.repos.d
total 60
-rw-r--r--. 1 root root 2523 Aug 23 02:30 Centos-7.repo

-rw-r--r--. 1 root root 2605 Jan  5  2023 remi.repo
```

#### 2.2.5.安装nginx和php

```shell
#安装nginx
[root@cf4a8afce6a4 /]# yum install nginx-1.24.0-1.el7.ngx.x86_64.rpm -y
#安装php及相关插件
[root@cf4a8afce6a4 /]# yum -y install php80-php-cli php80-php-common php80-php-devel php80-php-embedded php80-php-fpm php80-php-gd php80-php-mbstring php80-php-mysqlnd php80-php-pdo php80-php-opcache php80-php-xml php80-php-soap
```

#### 2.2.6.给php配置一个软连接，配置开机自启动

```shell
[root@f7118a887bfe /]# ln -sf /opt/remi/php80/root/usr/bin/php* /usr/local/bin
[root@f7118a887bfe /]# php -v

```

#### 2.2.7.配置nginx可解析php

```shell
#配置nginx可以解析php
[root@f7118a887bfe /]# vim /etc/nginx/conf.d/default.conf
server {
    listen       80;
    server_name  localhost;

#access_log  /var/log/nginx/host.access.log  main;

location / {
        root   /usr/share/nginx/html;
        index  index.php index.html index.htm;				#修改之一，添加php首页文件
    }

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html
    #

    location = /50x.html {
        root   /usr/share/nginx/html;
    }

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    # 修改之二，以下是php配置信息修改
    location ~ \.php$ {
        root           /usr/share/nginx/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

# deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}
#检查nginx语法错误
[root@f7118a887bfe /]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
