Hi all,
I've been trying the docker module and I'm facing permission issues.
My use case is the following:
- I installed ansible (ubuntu package 1.7.1), python pip (ubuntu package),
docker-py (pip package)
- I created a playbook with a simple task based on the docker module. I
want to create my container with ansible and provision it with ansible. I
don't want any ansible code to run inside my container.
I get this error:
msg: ConnectionError(MaxRetryError("UnixHTTPConnectionPool(host='localhost',
port=None): Max retries exceeded with url:
/run/docker.sock/v1.12/containers/json?all=1&limit=-1&trunc_cmd=1&size=0
(Caused by <class 'socket.error'>: [Errno 13] Permission denied)",),)
Intent : *create one container on localhost via ansible, (**maybe the
playbook does not understand it the same way)*
Pre-requisites: docker server is already up and running on localhost
I would be very grateful if anyone could explain me what I'm doing wrong
because I must be doing somthing wrong as my script is so trivial.
Thank you for your help.
Regards,
Louis
