Fixed via #921

[diptanu]

@mohitarora There will be support for un-archiving artifacts in Nomad 0.3.1, which will go out later tonight. The syntax for specifying artifacts has changed, so please refer the docs once we release.

[mohitarora]

Thanks @diptanu, waiting for new version.

[dadgar]

@mohitarora Just released 👍

Its exactly the same error I was getting before upgrade

Before upgrade i was able to see the error in client logs but not after upgrade.

[dadgar]

What is the exact artifact source? Obviously you can remove the host name but really want to see the extension. Also what is the contents of the artifact.

[mohitarora]

@dadgar

Artifact Source: https://ARTIFACT_LOCATION/build.zip
Whats in the zip file: an .exe file and all its dependencies (In other words, zip file has around 35 files, all at first level itself)

[dadgar]

Hmm it worked for me on a linux box. I will have to spin up a windows VM and try to reproduce

[mohitarora]

Thanks I will try on a linux box in the mean time. Can you share your zip file?

Just want to compare.

[dadgar]

I just did this to test:

$ zip artifact.zip main.go main_test.go
$ python -m SimpleHTTPServer

artifact {
     source = "http://127.0.0.1:8000/artifact.zip
}

[mohitarora]

Some Success, zip file is getting extractor to task directory now. Apparently there was an issue with zip file (Still need to figure the exact problem), but exe is still giving problems, need to figure out.

Thanks

[dadgar]

@mohitarora should we close this issue then? We can open up one related to the new problem

[mohitarora]

Yes, we can close this one. Thanks.
