Fails for version 1.16

[themathmagician]

If I bumb the FROM to version 1.16, the docker build fails with the following message:

 > [build 4/4] RUN go build -o /out/example .:
#8 0.337 go: cannot find main module

Can be fixed by changing the RUN in the dockerfile:

RUN go env -w GO111MODULE=auto && go build -o /out/example .

Thanks the report @themathmagician!

I'm not seeing that issue in the bump that I put up in a PR.

Do you have any local changes?

[themathmagician]

No changes, just a plain vanilla hello world project.
If you follow the example from bare minimum, you need the GO111MODULE auto, OR to have a mod file present.
But running go mod init is in the second part of the tutorial.

any status on this @chris-crone ?
thx

Sorry for the slow reply, I see what you mean @themathmagician: The first blog post's instructions do not work with Go 1.16+.

I recommend reading the blog posts to understand what the patterns do and then to use this git repo for code that works. The repo works as it has a go.mod file. I've also just bumped it to 1.17 in this PR.
