docker里面设置GO环境变量的问题 #1169

Closed zhanghanke closed 3 years ago

zhanghanke commented 3 years ago

在实践一下部署流程，在docker的时候报错:

go mod download: github.com/globalsign/mgo@v0.0.0-20181015135952-eeefdecb41b8: Get "https://proxy.golang.org/github.com/globalsign/mgo/@v/v0.0.0-20181015135952-eeefdecb41b8.info": dial tcp 142.251.42.241:443: i/o timeout go mod download: github.com/golang-jwt/jwt@v3.2.1+incompatible: Get "https://proxy.golang.org/github.com/golang-jwt/jwt/@v/v3.2.1+incompatible.info": dial tcp 142.251.43.17:443: i/o timeout go mod download: github.com/tal-tech/go-zero@v1.2.2: Get "https://proxy.golang.org/github.com/tal-tech/go-zero/@v/v1.2.2.info": dial tcp 142.251.42.241:443: i/o timeout

即时我自己打开/var/lib/jenkins/workspace/book/Dockerfile，添加一下RUN go env，发现打印的结果有点奇怪。 GO111MODULE没开on，提示下载不到。

如果我在/var/lib/jenkins/workspace/book/Dockerfile里面设置GO111MODULE=on，反倒会报不在GOPATH的错误。 有点不解啊。 ---> Running in d24b59b77efe GO111MODULE="on" GOARCH="amd64" GOBIN="" GOCACHE="/root/.cache/go-build" GOENV="/root/.config/go/env" GOEXE="" GOEXPERIMENT="" GOFLAGS="" GOHOSTARCH="amd64" GOHOSTOS="linux" GOINSECURE="" GOMODCACHE="/go/pkg/mod" GONOPROXY="" GONOSUMDB="" GOOS="linux" GOPATH="/go" GOPRIVATE="" GOPROXY="https://goproxy.cn,direct" GOROOT="/usr/local/go" GOSUMDB="sum.golang.org" GOTMPDIR="" GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64" GOVCS="" GOVERSION="go1.17.2" GCCGO="gccgo" AR="ar" CC="gcc" CXX="g++" CGO_ENABLED="0" GOMOD="/dev/null" CGO_CFLAGS="-g -O2" CGO_CPPFLAGS="" CGO_CXXFLAGS="-g -O2" CGO_FFLAGS="-g -O2" CGO_LDFLAGS="-g -O2" PKG_CONFIG="pkg-config" GOGCCFLAGS="-fPIC -m64 -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build3884164958=/tmp/go-build -gno-record-gcc-switches" Removing intermediate container d24b59b77efe ---> 0f9d207cc600 Step 9/19 : ADD go.mod . ---> 2028a80fb854 Step 10/19 : ADD go.sum . ---> d1cd0d58a36d Step 11/19 : RUN go mod download ---> Running in 6acbbb73482f Removing intermediate container 6acbbb73482f ---> 61fac67630c7 Step 12/19 : COPY . . ---> a3a82c730220 Step 13/19 : RUN go build -ldflags="-s -w" -o /app/user user/cmd/api/service/user/cmd/api/user.go ---> Running in e0e6ecf0a91d package user/cmd/api/service/user/cmd/api/user.go is not in GOROOT (/usr/local/go/src/user/cmd/api/service/user/cmd/api/user.go) The command '/bin/sh -c go build -ldflags="-s -w" -o /app/user user/cmd/api/service/user/cmd/api/user.go' returned a non-zero code: 1

跟踪到源码，发现在docker template里面已经有判断是不是中国的生成选项了。。后面应该完善一下文档。。

package docker

import ( "github.com/tal-tech/go-zero/tools/goctl/util" "github.com/urfave/cli" )

const ( category = "docker" dockerTemplateFile = "docker.tpl" dockerTemplate = `FROM golang:alpine AS builder

FROM alpine

RUN apk update --no-cache && apk add --no-cache ca-certificates tzdata ENV TZ Asia/Shanghai

你的意思是这个已经没有问题了，对吧？

你的意思是这个已经没有问题了，对吧？ 我修改了系统的时区后，生成的DOCKERFILE正常了。但Docker build仍然提示不在GOROOT里面

刚接触docker不久，了解比较少，待我研究一下，感谢回复。

问题解决了，阅读了goctl里面的代码 tools/docker/里面，原因是生成的Dockerfile的生成错误： 输入： /root/go/bin/goctl docker -go service/user/cmd/api/user.go 生成的Dockerfile里面的go build的路径明显不对（黑体字）user/cmd/api/service/user/cmd/api/user.go

FROM golang:alpine AS builder

LABEL stage=gobuilder

ENV CGO_ENABLED 0 ENV GOOS linux ENV GO111MODULE on ENV GOPROXY https://goproxy.cn,direct

WORKDIR /build/zero

RUN go env ADD go.mod . ADD go.sum . RUN go mod download COPY . . RUN go build -ldflags="-s -w" -o /app/user user/cmd/api/service/user/cmd/api/user.go

FROM alpine

RUN apk update --no-cache && apk add --no-cache ca-certificates tzdata ENV TZ Asia/Shanghai

WORKDIR /app COPY --from=builder /app/user /app/user

CMD ["./user"]

看了一下大佬的源码，发现生成Dockerfile的时候，默认模板里面有把GoRelPath+GoFile拼起来的逻辑， 是我用得不对，还是默认模板情况下有错？

const ( category = "docker" dockerTemplateFile = "docker.tpl" dockerTemplate = `FROM golang:alpine AS builder

LABEL stage=gobuilder

ENV CGO_ENABLED 0 ENV GOOS linux {{if .Chinese}}ENV GOPROXY https://goproxy.cn,direct {{end}} WORKDIR /build/zero

ADD go.mod . ADD go.sum . RUN go mod download COPY . . {{if .Argument}}COPY {{.GoRelPath}}/etc /app/etc {{end}}RUN go build -ldflags="-s -w" -o /app/{{.ExeFile}} {{.GoRelPath}}/{{.GoFile}}

FROM alpine

RUN apk update --no-cache && apk add --no-cache ca-certificates tzdata ENV TZ Asia/Shanghai

WORKDIR /app COPY --from=builder /app/{{.ExeFile}} /app/{{.ExeFile}}{{if .Argument}} COPY --from=builder /app/etc /app/etc{{end}} {{if .HasPort}} EXPOSE {{.Port}} {{end}} CMD ["./{{.ExeFile}}"{{.Argument}}] ` )

解决方法是自己创建一个模板，即 ~/.goctrl/docker/docker.tpl，把{{.GoRelPath}}/{{.GoFile}}里面的{{.GoRelPath}}/去掉。

求大佬指点！
