Problems with OctoDeploy in TeamCity

(Alvaro) #1

I have installed multiple instances of TeamCity (latest build 2018.2.2 (build 61245)) on different Debian 9 instances, and used the OctoDeploy plugin on it to push NuGet packages to my cloud instance of Octopus Deploy.

Roughly every other build I try to push to Octopus I get the following error in the log of the build project:

[16:36:56][Octopus Deploy] Running command:   dotnet Octo.dll push --server https://xxxxxxx.octopus.app --apikey SECRET --package /opt/teamcity-agent-2/work/xxxxxxxxx/xxxxxxxxxxxxx.nupkg

if I re-run the build straight after, most of the time the build finishes successfully and the NuGet packages gets pushed through.

I don’t understand what the issue here is?

Hi Alvaro,

Thanks for getting in touch.
The error message you are receiving seems to be network related. The frequency that you are receiving errors is concerning though.

How long does the connection take to fail? Is it immediate or is it taking some time before it fails?
Are you able to connect to the Octopus server using Octo.exe from a different machine that isn’t one of your build servers?
Are there any proxies between your build server and the public internet, or any firewalls that may be blocking or throttling traffic?
Can you also try running a trace route from your build server to the Octopus server and let me know the results.

Regards
Ben

Hi Ben,

The connection takes 30 seconds to fail, which is the default Socket timeout length it seems.

The servers in question are all Linux, so rather than using Octo.exe, it’s using the dotnet core Octo.dll file. As mentioned before, every other attempt works, but obviously for every 1 or 2 attempts, 1 of them will fail.

I’ve tried running the execution directly from bash, but I get the same random problems:

debian@build:/opt/teamcity-agent-1/temp/buildTmp/octo-temp/3.0/Core$ dotnet Octo.dll push --server https://xxxxxxx.octopus.app --apikey SECRET --package /opt/teamcity-agent-1/work/d1df6864f98d2599/xxxxxxx.nupkg --package /opt/teamcity-agent-1/work/d1df6864f98d2599/xxxxxxxxxxx.nupkg --package /opt/teamcity-agent-1/work/d1df6864f98d2599/xxxxxxxxx.nupkg

The build server is on a dedicated server with no proxies or firewalls in the way.

As I’ve been trying to get a traceroute done for you, I’ve spotted some DNS resolving issues, which may related to the openstack DNS itself, this may be the cause of the issue so I’ll go and change some nameservers first to see if this fixes the issue.
