Hello,
Can you confirm the entries that you're using as input to the action? I'm asking this for two reasons:
1. based on configuring the service to start with 127.0.0.1, I've had to configure my action to either use 127.0.0.1 or localhost (since my hosts file on the agent/dockerHost resolves localhost to 127.0.0.1) for it to work successfully. If I try using the machines hostname then it will return this message.
2. After fixing the "Server" field to use 127.0.0.1 I began getting a different error: server error. If I looked in nolio_all.log I found that it was returning:
Caught exception during JsonPath matching com.jayway.jsonpath.PathNotFoundException: No results for path: $['Id']
To track down the $['Id'] error I had to tail -f /var/log/messages.
This showed me that docker was seemingly responding with:
level=error msg="Handler for POST /containers/create returned error: invalid environment variable: "
This wasn't resolved until I added an environment variable and value into the "Env" field of my action. For example: var1=test
Also, from what I can tell you can only set 1 environment variable via the Env field of that specific action.
Kind regards,
Gregg
