Flynn: go app cannot find package and fails deployment

Created on 4 May 2016 · 19Comments · Source: flynn/flynn

Same project deploys to Heroku, but fails for flynn.
Any ideas what may be wrong here?

Have you run godep save? Make sure you have the latest version of godep with go get -u github.com/tools/godep. This might have to do with the change in how vendoring works over the past few Go releases.

@thomasmodeneis are you using an explicit buildpack? Flynn uses github.com/heroku/heroku-buildpack-go but from your output it seems you are using github.com/kr/heroku-buildpack-go?

lmars on 4 May 2016

I'm not using any explicit buildpack, is just the same code with a godeps dir and a goproc. Weird is that it works on heroku but fails on flynn for some odd reason.

thomasmodeneis on 4 May 2016

So I had another cluster that was up and running with an old version of this same software, but flynn there is about 2 months old. So I've deployed my code to this one, and well it worked just fine, what makes me believe this is a new defect on flynn, what do you think?

I think that github.com/dancannon/gorethink is probably cached. It looks like you have godep configured, have you vendored the package properly?

titanous on 5 May 2016

this is a complete new cluster i've created, is just no way it was cached as it could not be cached (its new).
Its all properly configured, if you read the report it says that it works for heroku and for a old version of flynn, but it fails for v20160504.0. :|

I'm not sure what to do here mate, is pretty strange.

thomasmodeneis on 5 May 2016

Yeah, I mean cached in heroku/the old cluster. Have you checked the vendoring configuration?

titanous on 5 May 2016

I will double check and update all dependencies / retry the cluster creation and install just to be on the safe side.

thomasmodeneis on 5 May 2016

hi @titanous I've upgraded dependencies and tested to install in other envs and they all work, including heroku, so I'm confused how to inspect further. How can I get access to the server that executed this build? I have a cluster of 3, how can I identify and connect to it?
Thanks

thomasmodeneis on 9 May 2016

Have you tried deploying to an entirely new app on Heroku? Did that work? There is no easy way to get at the build environment as it is in an ephemeral container that is destroyed at exit.

titanous on 9 May 2016

So I did a test, I've installed an old app with go 1.4.2 and it worked, so then I upgraded this same app to 1.6 and pushed to flynn and failed. Same behavior.

So it seems to be something related to Go 1.6. I've deployed the same app on heroku with no errors:

I can see that the command that flynn is running is go install -v -tags heroku . and it fails with errors, but heorku is using godep go install -v -tags heroku . and works fine.

thomasmodeneis on 9 May 2016

I tried with Go 1.6.2 and it was the same behavior, however I can see that its reporting go 1.6.2 as Deprecated, that must be wrong as heroku buildpack supports it go1.6 (installs go1.6.2)

Then I said ok lets me try 1.5 and see how that goes ? and 1.5 works fine.

Try running this and deploying again:

flynn env set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-go

titanous on 9 May 2016

That works, it will be very nice if you could include this step into the flynn docs as this seems to be required in order to have things running :)
Thanks @titanous

thomasmodeneis on 10 May 2016

I've updated the buildpack in #2806 which should fix this.

titanous on 10 May 2016

Thanks @titanous

thomasmodeneis on 11 May 2016

Hi @titanous

I'm running into the same problem now after updating it to 1.7. ('Ive executed cmd flynn env set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-go with no effect).

After reducing the Godeps.json to go1.6.2 the deployment works fine.

I see the same difference I had last time, after downgrade to 1.6.2 the log says: -----> Running: godep go install -v -tags heroku .

$ flynn version v20160819.0

Any ideas ?

Thanks

@titanous you where right, I had to update vendoring to use the vendor folder and kind of "migrate" from godeps to new vendor.
Thanks for the tip :)
