一.Dock基本操作

1. 對已啟動容器進行檔案掛載

<1> 關閉容器

<2> 切換Root使用者跳轉到容器資訊目錄：cd /var/lib/docker/containers/容器id/

<3> vi hostconfig.json 修改如下，將容器目錄/import繫結到主機/data目錄

"Binds": ["data:/import"]

<4>vi config.v2.json,修改如下，新增MountPoints:

"/import": {
   "Source": "/data",
   "Destination": "/import",
   "RW
 
": true,
   "Name": "",
   "Driver": "",
   "Type": "bind",
   "Propagation": "rprivate",
   "Spec": {
       "Type": "bind",
       "Source": "/data",
       "Target": "/import"
  },
   "SkipMountpointCreation": false
}

<5>啟動容器

2. Docker啟動nginx容器並掛載配置檔案

命令：

docker run -v /usr/local/nginx/default.conf:/etc/nginx/conf.d/default.conf \
 
-p 80:9443 \
--name nginx \
--restart always \
-d nginx

如果想使用80埠轉發則配置檔案命名default.conf不可修改，需要此檔案覆蓋容器中的相同檔案

server {
  listen       80;
  listen [::]:80;
  server_name localhost;
​
   #charset koi8-r;
   #access_log /var/log/nginx/host.access.log main;
​
location /api/basic_management {
      proxy_pass： http:
 
//10.22.30.20:31734
  }

location /api/data_center {
      proxy_pass： http://10.25.1.184:9000
  }

location /api/digital-bank-web {
      proxy_pass： http://10.25.1.184:8800
  }
​
  location / {
      root   /usr/share/nginx/html;
      index index.html index.htm;
  }
​
   #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;
  }
​
   # 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
   #
   #location ~ \.php$ {
   #   root           html;
   #   fastcgi_pass   127.0.0.1:9000;
   #   fastcgi_index index.php;
   #   fastcgi_param SCRIPT_FILENAME /scripts$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;
   #}
}

3. 修改報錯容器中的配置檔案

# 檢視容器報錯原因
[root@pro nginx]# docker logs nginx
nginx: [emerg] unknown directive "gizp" in /etc/nginx/nginx.conf:29
# 在此目錄找到nginx容器的配置檔案
[root@pro nginx]# cd /var/lib/docker/overlay2/
[root@pro overlay2]# find ./ -name nginx.conf
./7baeb968df6b073708cce37a182cf54fd033023a5eda6bb6d1077438d950ce6e/diff/etc/nginx/nginx.conf
# 將檔案修改正確
[root@pro overlay2]# vim ./7baeb968df6b073708cce37a182cf54fd033023a5eda6bb6d1077438d950ce6e/diff/etc/nginx/nginx.conf
# 重啟容器
[root@pro overlay2]# docker restart nginx
nginx

二. 檔案拷貝

1. 從容器中拷貝檔案到宿主機

執行命令格式：docker cp 容器名/容器ID:容器裡面的檔案路徑 宿主機對應的路徑

2.從宿主機拷貝檔案到容器

執行命令格式：docker cp 宿主機檔案對應路徑 容器名/容器ID:容器裡面對應的路徑

三.Centos7安裝

1.更新本地YUM

執行命令：yum update -y

2.安裝wget(已安裝的可跳過)

安裝命令：yum install wget

替換阿里映象：wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

生成本地倉庫快取：yum makecache

3.安裝docker

命令：yum install docker -y

初始化命令：

systemctl start docker  #啟動docker
systemctl enable docker #開機啟動docker
systemctl status docker #檢視docker狀態
