问题描述
我尝试在{em> 私有公司 网络使用go中构建docker-multi-stage-build图像：
FROM golang:latest as builder
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN GO111MODULE="on" CGO_ENABLED=0 GOOS=linux go build -o main ${MAIN_PATH}
FROM alpine:latest
LABEL maintainer="Kozmo"
RUN apk add --no-cache bash
WORKDIR /app
COPY --from=builder /app/main .
EXPOSE 8080
CMD ["./main"]
并获得x509: certificate signed by unknown authority错误
Step 1/13 : FROM golang:latest as builder

Step 2/13 : WORKDIR /app
---> Using cache
---> 6555644dbd16
Step 3/13 : COPY go.mod go.sum ./
---> 55d45a30f492
Step 4/13 : RUN go mod download
---> Running in 88c21c6b4fab
go: github.com/dgrijalva/jwt-go/[email protected]: Get "https://proxy.golang.org/github.com/dgrijalva/jwt-go/v4/@v/v4.0.0-preview1.mod": x509: certificate signed by unknown authority
The command '/bin/sh -c go mod download' returned a non-zero code: 1
make: *** [docker] Error 1
我试图在其中找到答案
X509: Certificate Signed by Unknown Authority (Running a Go App Inside a Docker Container)
，docker build: cannot get the github public repository,x509: certificate signed by unknown authority
和x509 certificate signed by unknown authority - go-pingdom
，但结果相同。
❗️如果添加-insecure标志
...
RUN go env -w GOPROXY=direct GOFLAGS="-insecure"
COPY go.mod go.sum ./
...
至Dockerfile??unrecognized import path错误 包装 先前的x509错误和 unreachable 软件包更改为golang.org/x/crypto
go: golang.org/x/[email protected]: unrecognized import path "golang.org/x/crypto": https fetch: Get "https://golang.org/x/crypto?go-get=1": x509: certificate signed by unknown authority
出什么问题❓
（我知道当git获得依赖时，证书和身份验证存在问题，但是我尝试使构建映像的过程更加普遍）
