Heat can't connect to docker server on VM
I installed docker plugin for heat. Then I try create a HOT script to test:
getdocker.sh is simply a downloaded version of #include https://get.docker.io
The script is modified from this example, since the example is incorrect. Strangely, I got this error when heat creating container:
Resource Create Failed: Connectionerror: Httpconnectionpool(Host='22.214.171.124', Port=80): Max Retries Exceeded With Url: /V1.9/Containers/Create (Caused By <Class 'Socket.Error'>: [Errno 113] Ehostunreach)
I checked on the VM, docker is successfully installed, but it run on local socket:
Heat can't connect to that socket. Did I misconfigured docker plugin?
