Description

should we patch docker-1.9? Patch for Docker 1.9: https://github.com/projectatomic/docker/pull/156 However, Dan, I think the patches for logging daemon API call don't seem to be working well (anymore), output from latest docker (and probably 1.10.x version): May 12 18:20:41 localhost.localdomain docker[10929]: time="2016-05-12T18:20:41.964145762+02:00" level=warning msg="tcpconn is not a struct" May 12 18:20:41 localhost.localdomain docker[10929]: time="2016-05-12T18:20:41.964217101+02:00" level=error msg="Unable to read peer creds and server socket address: bad file descriptor" I think they may be re-worked definitely fixed in docker-1.10 (if you could try it out, that would be awesome) Fixed in docker-1.10. @runc0m - I'll try to reproduce this with 1.10 What's more troubling about this problem is that the last time it was reported in BZ1275399, it was reported as fixed + verified with 1.9.1-23: https://bugzilla.redhat.com/show_bug.cgi?id=1275399#c28 So did the patch get lost somewhere along the way to 1.9.1-40? Looks like it got accidently dropped. I lied. I can't (easily) test my kube configuration with 1.10, because the our version of kube 1.2 in RHELAH 7.2.4 requires docker 1.9 I might be able to try in Fedora, but I've not crossed that bridge yet. Seeing this too in an OSE 3.2 installation on rhel-ah If we are still seeing this on docker-1.10.3-25 then the bug is not fixed. Seeing the logspam that Antonio mentioned in Comment 3[1] in the OpenShift CI AMIs: May 26 05:48:36 ip-172-18-1-46.ec2.internal forward-journal[2108]: time="2016-05-26T05:48:36.316938115-04:00" level=warning msg="ResponseWriter does not contain a field named conn" May 26 05:48:36 ip-172-18-1-46.ec2.internal forward-journal[2108]: time="2016-05-26T05:48:36.316987952-04:00" level=error msg="Unable to read peer creds and server socket address: bad file descriptor" The OpenShift AMIs are built with: $ docker version Client: Version: 1.10.3 API version: 1.22 Package version: docker-common-1.10.3-25.el7.x86_64 Go version: go1.4.2 Git commit: 86bbf84/1.10.3 Built: OS/Arch: linux/amd64 Server: Version: 1.10.3 API version: 1.22 Package version: docker-common-1.10.3-25.el7.x86_64 Go version: go1.4.2 Git commit: 86bbf84/1.10.3 Built: OS/Arch: linux/amd64 [1] https://bugzilla.redhat.com/show_bug.cgi?id=1335635#c3 I'm taking care of the other bogus warnings though - I'll fix these in both RHEL and Fedora 1.10 but we should have another BZ tracking those other bogus warnings. I'll try to fixup rhel 1.9 but no promise. Fedora fix for 1.10.3: https://github.com/projectatomic/docker/commit/5e3f07110aeab2fc7674cf87c0a4669ae0215ee4 RHEL fix for 1.10.3: https://github.com/projectatomic/docker/commit/6246c4a567cfd6be390439f66965c80fec1b493a now we can correctly see the correct log line: May 30 18:52:46 localhost.localdomain docker[27852]: time="2016-05-30T18:52:46.113496163+02:00" level=debug msg="GET /v1.22/version" May 30 18:52:46 localhost.localdomain docker[27852]: time="2016-05-30T18:52:46.118623888+02:00" level=debug msg="{Action=version, Username=amurdaca, LoginUID=27212, PID=27923}" To summarize:
$SUBJECT ("Failed to get pwuid struct: user: unknown userid " log spam) has been fixed in rhel7-1.9 and it's fixed in rhel7-1.10.3 (if you don't see the fix, we need to rebuild it probably)
The other, annoying, log spam like the ones in https://bugzilla.redhat.com/show_bug.cgi?id=1335635#c3 have been fixed with the above patches (see previous comment)
