## Summary "Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" even though ``` root@absx-gce-gitlab-runner:~# docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS runner-8e48a51b-absx-scale-runner-1489746821-91eb6745 - google Running tcp://10.132.0.5:2376 v1.12.6 ``` ## Steps to reproduce Installed based on this project: https://github.com/jerryjj/gitlab-runner-gce/ (This is old and needs tweaks) Everything seems to run fine. gitlab-ci-multi-runner starts, fires up the first runner (IdleCount = 1) and immediately starts logging the error: "Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" ## Actual behavior When a build gets started the same machine is being used to build, while a second runner is started to keep IdleCount = 1. When the build is done, 2 machine stays and does not get removed, even though it should based on the IdleTime and IdleCount. ## Expected behavior Why the error? IdleCount should work and runners should be removed. ## Relevant logs and/or screenshots ``` Mar 17 11:46:43 absx-gce-gitlab-runner gitlab-runner[2977]: time="2017-03-17T11:46:43Z" level=info msg="Machine created" name=runner-8e48a51b-absx-scale-runner-1489751144-9f54b587 now=2017-03-17 11:46:43.845891434 +0000 UTC retries=0 time=58.948970057s #012<nil> Mar 17 11:46:43 absx-gce-gitlab-runner gitlab-ci-multi-runner[2977]: time="2017-03-17T11:46:43Z" level=info msg="Machine created" fields.time=58.948970057s name=runner-8e48a51b-absx-scale-runner-1489751144-9f54b587 now=2017-03-17 11:46:43.845891434 +0000 UTC retries=0 time=58.948970057s Mar 17 11:46:47 absx-gce-gitlab-runner gitlab-runner[2977]: time="2017-03-17T11:46:47Z" level=warning msg="Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" #012<nil> Mar 17 11:46:47 absx-gce-gitlab-runner gitlab-ci-multi-runner[2977]: time="2017-03-17T11:46:47Z" level=warning msg="Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" Mar 17 11:46:50 absx-gce-gitlab-runner gitlab-runner[2977]: time="2017-03-17T11:46:50Z" level=warning msg="Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" #012<nil> Mar 17 11:46:50 absx-gce-gitlab-runner gitlab-ci-multi-runner[2977]: time="2017-03-17T11:46:50Z" level=warning msg="Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" Mar 17 11:46:53 absx-gce-gitlab-runner gitlab-runner[2977]: time="2017-03-17T11:46:53Z" level=warning msg="Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" #012<nil> Mar 17 11:46:53 absx-gce-gitlab-runner gitlab-ci-multi-runner[2977]: time="2017-03-17T11:46:53Z" level=warning msg="Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" Mar 17 11:46:56 absx-gce-gitlab-runner gitlab-runner[2977]: time="2017-03-17T11:46:56Z" level=warning msg="Failed to update executor docker+machine for 8e48a51b No free machines that can process builds" #012<nil> ``` ## Environment description ``` concurrent = 5 check_interval = 0 [[runners]] url = "https://gitlab.com/ci" name = "absx-scale-runner" token = "8e48a[..]3cfde0" executor = "docker+machine" limit = 10 [runners.docker] image = "docker:latest" privileged = true disable_cache = false cache_dir = "/cache" volumes = ["/cache"] [runners.machine] OffPeakPeriods = [ "* * 0-8,20-23 * * mon-fri *", "* * * * * sat,sun *" ] OffPeakIdleCount = 0 OffPeakIdleTime = 360 OffPeakTimezone = "Europe/Berlin" IdleCount = 1 IdleTime = 60 MaxBuilds = 10 MachineDriver = "google" MachineName = "absx-scale-runner-%s" MachineOptions = [ "google-project=abusix-gitlab-ci-scaler", "google-zone=europe-west1-c", "google-machine-type=n1-standard-4", "google-machine-image=coreos-cloud/global/images/coreos-stable-1298-5-0-v20170228", "google-tags=gitlab-ci-runner-worker,project-noip", "google-preemptible=true", "google-use-internal-ip=true", "google-use-internal-ip-only=true" ] ``` ### Used GitLab Runner version Version: 1.11.1 Git revision: a67a225 Git branch: 1-11-stable GO version: go1.7.5 Built: Fri, 03 Mar 2017 12:35:58 +0000 OS/Arch: linux/amd64
