无法 docker-从代理后面撰写

Question

我正在尝试在公司代理后面使用 docker-compose build，但出于某种原因，none 您插入代理设置的区域似乎允许它完成这些步骤。

我使用的是 CentOS 8 服务器。

错误信息：

[root@centos8server docker]# docker-compose build
    postgres uses an image, skipping
    start_dependencies uses an image, skipping
    Building custom-docker

    Step 1/15 : FROM swift:5.2.3 as builder

我最初的想法是 CentOS 服务器使用的 apt 和 apt-get 并不存在，但我随后在家中构建了没有代理限制的服务器，它就可以正常工作。我可以 wget 地址并且没有问题。

我尝试在以下方面添加代理：

1. proxy for build and compose

除了我在任何用户帐户中都没有 .docker 文件夹，所以我创建了目录和文件

nano ~/.docker/config.json
{
    "proxies": {
        "default": {
            "httpProxy": "http://proxy.server:port",
            "httpsProxy": "http://proxy.server:port",
            "noProxy": "localhost,127.0.0.1"
        }
    }
}

2。 Proxy for environment

3。 Proxy for sysconfig

我唯一知道的是过去一直存在的问题是我们的代理是 Basic-Auth 但一直无法找到如何添加它或是否有必要添加。

您需要在 Dockerfile 本身中添加代理设置：

# above apt-get
ENV http_proxy http://user:password@proxy.domain.ltd:[PORT]
ENV https_proxy http://user:password@proxy.domain.ltd:[PORT]

# above git
# basic proxy auth if needed
RUN git config --global http.proxy http://user:password@proxy.domain.ltd:[PORT] && \
    git config --global https.proxy http://user:password@proxy.domain.ltd:[PORT] && \
    git config --global http.proxyAuthMethod 'basic' && \
    git config --global https.proxyAuthMethod 'basic'
