我尝试建立go图像在私人公司网络使用docker-多阶段构建:
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"]
and get x509: certificate signed by unknown authority error
Step 1/13 : FROM golang:latest as builder
---> 2421885b04da
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：未知机构签署的证书（运行 Go 应用程序）
在 Docker 容器内）
and
docker build：无法获取github公共存储库，x509：
未知权威机构签署的证书
and
由未知权威机构签署的 x509 证书 - go-pingdom
，但结果是一样的。
❗️如果添加-insecure flag
...
RUN go env -w GOPROXY=direct GOFLAGS="-insecure"
COPY go.mod go.sum ./
...
to Dockerfile
