[英]Google App Engine Flex Container Deployment Issues
I am trying to deploy my Go 1.14 microservices application on to Google's Flexible environment.我正在尝试将我的 Go 1.14 微服务应用程序部署到 Google 的灵活环境中。 I read that there are issues with finding GOROOT, and how it is unable to obtain the correct dependencies.我读到查找 GOROOT 存在问题,以及它如何无法获得正确的依赖项。
I wanted to use the flexible environment because I needed to do port forwarding.我想使用灵活的环境,因为我需要做端口转发。 Since my domain name was used to run the actual application, I wanted port 8081 to run my microservices.由于我的域名用于运行实际应用程序,因此我希望端口 8081 来运行我的微服务。
I followed the instruction from this link:我按照此链接中的说明进行操作:

I tried option 3. This is my gitlab-ci.yaml configurations file.我尝试了选项 3。这是我的 gitlab-ci.yaml 配置文件。
# .gitlab-ci.yaml
stages:
- build
- deploy
build_server:
stage: build
image: golang:1.14
script:
- go mod vendor
- go install farmcycle.us/user/farmcycle
artifacts:
paths:
- vendor/
deploy_app_engine:
stage: deploy
image: google/cloud-sdk:270.0.0
script:
- echo $SERVICE_ACCOUNT > /tmp/$CI_PIPELINE_ID.json
- gcloud auth activate-service-account --key-file /tmp/$CI_PIPELINE_ID.json
- gcloud --quiet --project $PROJECT_ID app deploy app.yaml
after_script:
- rm /tmp/$CI_PIPELINE_ID.json
This my app.yaml configuration file这是我的 app.yaml 配置文件
runtime: go
env: flex
network:
forwarded_ports:
- 8081/tcp
When I deployed this using the Git CI pipeline.当我使用 Git CI 管道部署它时。 Build stage passes, but the Deploy stage failed.构建阶段通过,但部署阶段失败。

This was the error.这是错误。 Honestly I am not really sure what this error is and how to fix it.老实说,我不太确定这个错误是什么以及如何修复它。
Surprisingly, even using the latest Go runtime, runtime: go1.15
, go modules appear to not be used.令人惊讶的是,即使使用最新的 Go 运行时runtime: go1.15
,似乎也没有使用 go 模块。 See golang-docker .请参阅golang-docker 。
However, Flex builds your app into a container regardless of runtime
and so, in this case, it may be better to use a custom runtime and build your own Dockerfile?但是,Flex 将您的应用程序构建到容器中而不考虑runtime
,因此,在这种情况下,使用自定义运行时并构建您自己的 Dockerfile 可能更好?
runtime: custom
env: flex
Then you get to use eg Go 1.15
and go modules (without vendoring) and whatever else you'd like.然后你可以使用例如Go 1.15
和 go 模块(没有vendoring)以及任何你想要的。 For a simple main.go
that uses modules eg:对于使用模块的简单main.go
,例如:
FROM golang:1.15 as build
ARG PROJECT="flex"
WORKDIR /${PROJECT}
COPY go.mod .
RUN go mod download
COPY main.go .
RUN GOOS=linux \
go build -a -installsuffix cgo \
-o /bin/server \
.
FROM gcr.io/distroless/base-debian10
COPY --from=build /bin/server /
USER 999
ENV PORT=8080
EXPOSE ${PORT}
ENTRYPOINT ["/server"]
This ought to be possible with Google's recently announced support for buildpacks but I've not tried it. Google 最近宣布支持 buildpack,这应该是可能的,但我还没有尝试过。
