Question

使用docker-compose在现有的dockerfile上进行一些细微更改会生成失败，

似乎不使用代理？

docker-compose.yml

version: "3.7"
services:
  samba:
    #image: pwntr/samba-alpine
    build:
      context: .
      dockerfile: Dockerfile
    container_name: samba
    volumes:
      - /some/path:/shared:ro
    restart: unless-stopped

我尝试使用代理详细信息设置args和environment部分，但是没有区别。

version: "3.7"
services:
  samba:
    #image: pwntr/samba-alpine
    build:
      context: .
      dockerfile: Dockerfile
#      args: # Environment variables available at build-time
#        - http_proxy=http://127.0.0.1:3128
#        - https_proxy=http://127.0.0.1:3128
#        - HTTP_PROXY=http://127.0.0.1:3128
#        - HTTPS_PROXY=http://127.0.0.1:3128
#    environment: # Environment variables available at container run-time
#      - http_proxy=http://127.0.0.1:3128
#      - https_proxy=http://127.0.0.1:3128
#      - HTTP_PROXY=http://127.0.0.1:3128
#      - HTTPS_PROXY=http://127.0.0.1:3128
    container_name: samba
    volumes:
      - /some/path:/shared:ro
    restart: unless-stopped

如果我使用docker run或通过图像，一切正常。

version: "3.7"
services:
  samba:
    image: pwntr/samba-alpine
    container_name: samba
    volumes:
      - /some/path:/shared:ro
    restart: unless-stopped

服务器/主机正在运行Alpine Linux，并且连接正常。

docker info | grep -i proxy
HTTP Proxy: http://127.0.0.1:3128/
HTTPS Proxy: http://127.0.0.1:3128/

Answer 1

尝试一下 docker build -t localhost/smb:v1 .

最好将RUN apk --no-cache upgrade && apk --no-cache add samba samba-common-tools supervisor更改为RUN apk --no-cache --upgrade add samba samba-common-tools supervisor，以避免出现多个网络请求。

Answer 2

以防其他人遇到问题。

运行ifconfig并找到docker0的IP地址

编辑cntlm.conf并添加以下内容

Listen 172.17.0.1:3128＃docker0的IP地址

重新启动cntlm

在/root/.docker/config.json创建配置文件并添加以下内容

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://172.17.0.1:3128",
     "httpsProxy": "http://172.17.0.1:3128",
     "ftpProxy": "http://172.17.0.1:3128"
   }
 }
}
