Just run hover build *** --docker

Do I need to write a Dockerfile？

qianniancn picture qianniancn on 28 Apr 2020

Nope. Automatically done for you.

jld3103 picture jld3103 on 28 Apr 2020

@qianniancn did it work?

jld3103 picture jld3103 on 28 Apr 2020

@jld3103 Sorry, failed to cross compile to Linux on Windows platform.

It's early morning Beijing time. I'm going to bed. I'll see what the problem is tomorrow.

qianniancn picture qianniancn on 28 Apr 2020

What Windows version do you have? Docker doesn't work on all Windows versions. They only let you use it on professional versions. Anyway you could still install a Linux toolchain on your Windows machine.

jld3103 picture jld3103 on 28 Apr 2020

@jld3103 My windows is professional. Docker can be built normally.

Ok then lets look at it later when you are awake again

@jld3103 It seems that it is caused by Chinese network problems. #406 #392

In China, Google's services, including golang.org, are inaccessible.

Is it possible to add GOPROXY to the dockerfile? https://goproxy.io/ or https://goproxy.cn/

qianniancn picture qianniancn on 29 Apr 2020

qianniancn picture qianniancn on 29 Apr 2020

hover should automatically pickup your GOPROXY in the docker container. Another problem you are running into is that you have no AndroidManifest.xml which hover needs to find the organization name. You can create a simple placeholder manifest with only your organization name.

@jld3103 The question is still this：

@jld3103 I'm not following the development of the hover toolkit.

hover should automatically pickup your GOPROXY in the docker container

Is this true?

@qianniancn what's the output of:

docker run --rm -it goflutter/hover:latest go env

Edit - Additional info.
@jld3103

$ GOPROXY=https://something.com go env GOPROXY

pchampio picture pchampio on 29 Apr 2020

@pchampio It seems that the local GOPROXYis not mapped in the docker.

It should be while running with docker. I'll look into that later this day

Can we close this in favor of #392 ?

jld3103 picture jld3103 on 5 May 2020

392 was about host compiling.

This issue is about docker compiling.

The host compiling issue was resolved by:

go env -w GOPROXY=https://goproxy.cn,direct

This issue isn't resolved!
It seems that the host GOPROXY is not mapped in the docker.

pchampio picture pchampio on 5 May 2020

GOPROXY seems to need to be mapped into docker

qianniancn picture qianniancn on 5 May 2020

That should already be happening https://github.com/go-flutter-desktop/hover/blob/7ba55114fc956a2d2ef52276538010b3d7a45142/cmd/docker.go#L63 I don't understand why it doesn't work

jld3103 picture jld3103 on 5 May 2020

The output of go env GOPROXY should be used instead of Getenv!

@qianniancn can you try https://github.com/go-flutter-desktop/hover/pull/114 ? You need to clone the branch and then do a go install in the cloned hover directory. To go back just install hover normally again.

@jld3103 Well, I'll have a look tomorrow. I have a headache today.

qianniancn picture qianniancn on 5 May 2020

This issue has been resolved in go-flutter-desktop/hover#114 , thank you all
