Migrate CI from Travis to GitHub Actions

[billyvg]

Travis sprung some surprise billing changes on us awhile, so we are now prioritizing removing usage of TravisCI completely. This issue will be used by @getsentry/productivity to track overall progress across the organization, but please let us know here if there's anything we should be aware of.

@kamilogorek Is this referring to the main branch on https://github.com/golang/go ? I don't see an official support by the setup-go action so it might take some effort to obtain that functionality.

sentry-go/.travis.yml

Line 7 in db5fae9

- master

@billyvg any suggestions on how to emulate Travis' webhook and notifications? (I see some unverified Webhook actions)

sentry-go/.travis.yml

Lines 51 to 59 in db5fae9

	notifications:
	webhooks:
	urls:
	- https://zeus.ci/hooks/befe9810-9285-11e9-b01a-0a580a281808/public/provider/travis/webhook
	on_success: always
	on_failure: always
	on_start: always
	on_cancel: always
	on_error: always

@kamilogorek What's happening for this error?

I would defer to Kamil re: how we want to handle zeus.

@kamilogorek Would I also be able to get write access? It will allow me to run the GH actions as part of the PR.

What's happening for this error?

I think it's trying to build with GO111MODULE=off code checked-out outside of GOPATH, that won't work.
I need to see what's the best practice here, one solution is to set GOPATH explicitly to $GITHUB_WORKSPACE.

I would defer to Kamil re: how we want to handle zeus.

We don't need a replacement for Zeus, we already use GH to check build status in Craft (and note we don't need any artifact provider for Go), so we can remove the webhook without affecting the release process.

@billyvg @rhcarvalho would you mind reviewing this? #314

[armenzg]

@rhcarvalho do you have some steps as to how to quickly get a go version from source checkout?

I'm looking at the Travis code and I can't figure out what steps are taken to get a development version installed.

[armenzg]

Merged: #314
Next: #319

@rhcarvalho r? for #319

FYI You will need to change the "Required checks" at the repository level.

[armenzg]

Hi @rhcarvalho how do you feel about dropping the Travis CI? No pressure. Just curious if there's anything left to validate.

[armenzg]

@rhcarvalho Would it be possible to land this? In February, sentry-go used more than 50% of our Travis credits.
