docker_image/docker_container not working - The error was: SyntaxError: invalid syntax
Randeepak Sandhu
I am trying to build docker image passing in Dockerfile on the same host where Dockerfile and other related project files resides. Without using ansible, I am able to run my Dockerfile build an image out of it and start a container that is if i use docker itself. But when i try to put these steps into ansible playbook, it fails. On this host machine, docker, ansible, python-pip and docker sdk for python are installed
