Concourse CI Windows Worker

Question

I'm trying to setup a Concourse CI environment with a Windows 7 worker.

I have one machine under Ubuntu Server (16.04) hosting my TSA server and one worker (for the support of git resources), and a second one under Windows 7 hosting a worker.

Everything seems to work fine as:

• I can login into the web ui

• the fly -t my_concourseci workers command returns :

   name containers platform tags team state version ubuntu 1 linux none none running 1.1 windows7 0 windows none none running 1.1 

• the fly -t my_concourseci execute -c test.yml command returns:

   executing build 146 initializing running echo Hello World! Hello World! 

  with the following content in test.yml file:

   platform: windows run: path: echo args: [ "Hello World!" ] 

Nevertheless when I add an input to my task:

    platform: windows

    > inputs:
    >  - name: concourse

    run:
      path: echo
      args: [ "Hello World!" ]

I get the following error:

executing build 148
% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                             Dload  Upload   Total   Spent    Left  Speed

initializing
failed to stream in to volume
errored

If I look at the windows worker log I got this error that comes up:

{"timestamp":"1500642862.643555164",
"source":"baggageclaim",
"message":"baggageclaim.api.volume-server.stream-in.bad-stream-payload",
"log_level":1,
"data":{"error":"tar extract failed (exit status 2). output: \"\\ngzip: stdin: not in gzip format\\n/usr/bin/tar: Child returned status 1\\n/usr/bin/tar: Error is not recoverable: exiting now\\n\"",
"session":"2.1.8730",
 "volume":"15bf1fc6-0727-4962-6c84-18446e54ab96"}
}

Any ideas about what can cause a not in gzip format error ? Knowing that if I run the exact same task on a linux platform every works fine.

platform: linux

Answer 1

Launch powershell as Administrator, and run the concourse_worker.exe from there. That worked for me.

I am running a Windows Server 2016 Base on AWS based on this AMI ami-e1876a98

Answer 2

Thanks for your answers, it helps me solve my problem.

I were starting my concourse worker within a MSYS 1.0 environment. The thing is that MSYS contains tar and gunzip binaries within the $PATH . When I started concourse worker inside a Power Shell or cmd.exe without any MSYS unix-like binaries in the $PATH it worked like a charm !

Note: Be sure to have no MSYS binaries in the $PATH Windows environment variable for this to work, especially check that Git-Bash environment tools are not added to your windows $PATH environment variable.

Thanks again.
