proxy_test fails when docker is installed in travis environment #187

Closed mrichmon closed 8 years ago

mrichmon commented 8 years ago

proxy_test is failing with a runtime error due to an invalid/nil pointer dereference. This was triggered by adding docker to the travis test environment. (Docker is being added as part of automatic testing against a live kubernetes system.)

No further debugging yet.

Travis config file is:

sudo: required

services:
  - docker

language: go
go:
  - 1.5
  - 1.6

before_install:
  - docker pull gcr.io/google_containers/hyperkube-amd64:v1.2.4
  - docker ps -a

before_script:
  - curl -L  https://github.com/coreos/etcd/releases/download/v2.3.1/etcd-v2.3.1-linux-amd64.tar.gz -o etcd-v2.3.1-linux-amd64.tar.gz
