Failed to update executor docker+machine for 9fb5fe99 No free machines that can process builds

I get the above message whenever I run gitlab-runner. The runner is on an aws ubuntu 14.04 instance with docker-machine version 0.6.0 (also tried it with the previous version, same situation) This is my config:

concurrent = 10

[[runners]]
  name = "Coordinator"
  url = "my url"
  token = "my token"
  executor = "docker+machine"
  [runners.docker]
    image = "ubuntu:14.04"
    privileged = false
    volumes = ["/cache"]
    allowed_images = ["*", "*/*", "*/*/*"]
    allowed_services = ["*", "*/*"]
  [runners.machine]
    IdleCount = 1
    IdleTime = 1800
    MaxBuilds = 100
    MachineDriver = "amazonec2"
    MachineName = "auto-scale-%s"
    MachineOptions = [
      "amazonec2-vpc-id=my vpc id",
      "amazonec2-subnet-id=my subnet id",
      "amazonec2-zone=b",
      "amazonec2-access-key=my key",
      "amazonec2-secret-key=my secret",
      "amazonec2-region=us-west-2",
      "amazonec2-private-address-only",
      "engine-registry-mirror=http://172.31.27.193:6000"]
  [runners.cache]
    Insecure = false

Using gitlab-runner version 1.2.0~beta.99.ga2cf2c6 but I get the same error in the current stable 1.1.3 ( I believe)

Also, docker-machine ls comes back empty every time, but I do see an ec2 instance spin up.

Update: it turns out docker-machine was being run as the root user, and I needed to su to root to see what was going on. So far, it looks like it’s trying to provision an ami with docker, it just takes forever on a micro. Problem not solved quite yet, I need to see how this resolves itself first.

Hi,
if was running in the same problem. It seems everything is working, but syslog gets hammered with those messages.

Did you make any progress or found out where this issues is coming from?

Thanks

Tobias

I am now getting that as well. Any updates?

I’m back here and i’ve found that since I have to invoke gitlab-runner as root using sudo, it also seems to create images using docker-machine as root as well, which makes the machines “invisible” to docker-machine when run as another user. It’s notable that the recommendations from docker seem to be never to run docker-machine as root. Please advise.
