我使用Linux Mint Sylvia开发公司代理（Docker是通过Ubuntu 16.04.3 Xenial源安装的。）
$ docker -v
Docker version 17.12.1-ce, build 7390fc6
我已按照这些步骤通过docker pull实际下载了一些图像。
我的http-proxy.conf：
$ cat /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=http://my_user:my_pass@company_proxy:3128/"
Environment="HTTPS_PROXY=https://my_user:my_pass@company_proxy:3128/"
Environment="NO_PROXY=localhost,127.0.0.0/8"
我的/etc/default/docker：
# If you need Docker to use an HTTP proxy, it can also be specified here.
#export http_proxy="http://127.0.0.1:3128/"
export http_proxy="http://my_user:my_pass@company_proxy:3128"
export https_proxy="https://my_user:my_pass@company_proxy:3128"
export HTTP_PROXY="http://my_user:my_pass@company_proxy:3128"
export HTTPS_PROXY="https://my_user:my_pass@company_proxy:3128"
我需要在多级Alpine容器中运行curl，为了简单起见，我构建了这个类似于我想要完成的并且具有相同错误的简单图像。 / p>
FROM alpine:3.7
ENV HTTP_PROXY http://my_user:my_pass@company_proxy:3128
ENV HTTPS_PROXY https://my_user:my_pass@company_proxy:3128
RUN apk add --no-cache curl
CMD ["curl","-v","--tlsv1","https://www.docker.io/"]
用
构建$ docker build --network host --rm -t test/alpine:curl .
在没有--network host的情况下运行。
$ docker run --rm test/alpine:curl
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0* Could not resolve proxy: company_proxy

使用--network host。
$ docker run --network host --rm test/alpine:curl
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

我是Docker的初学者并且已经在2个wifi网络中测试了这个图像（两个都没有代理），容器运行得很好。可能导致此SSL错误的任何提示？
// main.go
package main
import (
"os/exec"
"os"
"log"
)
func main() {
c := exec.Command("curl","--tlsv1","-kv","-X","PATCH","-d",`{"something" : "something"}`, `https://<firebase-link>`);
c.Stdout = os.Stdout
c.Stderr = os.Stderr
err := c.Run()
checkerr(err)
}
func checkerr(err error) {
if err != nil{
log.Fatal(err.Error())
panic(err)
}
}
最初的Dockerfile：
# This image only builds the go binaries
FROM golang:1.10-alpine as goalpine-image
ENV HTTP_PROXY http://my_user:my_pass@company_proxy:3128
ENV HTTPS_PROXY https://my_user:my_pass@company_proxy:3128
ENV FULL_PATH /go/src/<project-name>
WORKDIR $FULL_PATH
# Add the source code:
ADD . $FULL_PATH
# Build it:
RUN cd $FULL_PATH \
&& CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o bin/<project-name>
# This image holds the binaries from the previous
FROM alpine
RUN apk add --no-cache bash curl\
&& mkdir build
ENV WORD_DIR=/build
WORKDIR WORK_DIR
COPY --from=goalpine-image /go/src/<project-name>/bin ./
CMD ["./<project-name>"]
答案 0 :(得分：2)
我已经编辑了我的问题以包含有关我原始问题的更多信息，奇怪的是问题仍然存在于玩具图像中。所以，如果有人再遇到这个问题，这就是我解决的问题。
多阶段Dockerfile。似乎两个阶段都需要访问代理环境。
# This image only builds the go binaries
FROM golang:1.10-alpine as goalpine-image
ARG http_proxy
ARG https_proxy
ENV HTTP_PROXY $http_proxy
ENV HTTPS_PROXY $https_proxy
# Build envs
ENV FULL_PATH /go/src/<project-name>
WORKDIR $FULL_PATH
# Add the source code:
ADD . $FULL_PATH
# Build it:
RUN cd $FULL_PATH \
&& apk update \
&& apk add --no-cache curl \
&& CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o bin/<project-name>
# This image holds the binaries from the previous
FROM alpine:3.7
ENV HTTP_PROXY $http_proxy
ENV HTTPS_PROXY $https_proxy
RUN apk update \
&& apk add --no-cache bash curl\
&& mkdir build
ENV WORD_DIR=/build
WORKDIR WORK_DIR
COPY --from=goalpine-image /go/src/<project-name>/bin ./
CMD ["./<project-name>"]
确保将
http_proxy和https_proxy设置为环境 我的变量是/etc/profile。
docker build --rm --build-arg http_proxy=$http_proxy --build-arg https_proxy=$https_proxy --network host -t <project-name>:multi-stage .
docker container run --rm --network host <project-name>:multi-stage
