Using 'docker_* tasks' conflicts with minikube environment from chapter 2.

[gimballock]

ansible-for-kubernetes/ansible-containers/main.yml

Line 11 in 555e16d

docker_image:

If using the same shell env from chapter 2 where we ran:

$ minikube docker-env
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://127.0.0.1:55002"
export DOCKER_CERT_PATH="/Users/eprice/.minikube/certs"
export MINIKUBE_ACTIVE_DOCKERD="minikube"
# To point your shell to minikube's docker-daemon, run:
# eval $(minikube -p minikube docker-env)
$ eval $(minikube docker-env)

Then I get errors with 'docker_image' and 'docker_container' like this:

TASK [Ensure Docker registry image is present.] *************************************************
fatal: [127.0.0.1]: FAILED! => {"changed": false, "msg": "Error connecting: Error while fetching server API version: HTTPSConnectionPool(host='127.0.0.1', port=55002): Max retries exceeded with url: /version (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x10bf36970>: Failed to establish a new connection: [Errno 61] Connection refused'))"}

To get around this I have to either use a new shell or run the following:

$ minikube docker-env -u
unset DOCKER_TLS_VERIFY;
unset DOCKER_HOST;
unset DOCKER_CERT_PATH;
unset MINIKUBE_ACTIVE_DOCKERD;
$ eval $(minikube docker-env -u)

Here's what I've found

After downgrading kubernetes and openshift python packages and restarting minikube I still see the same issue.

$ pip3 list

Sorry, I should have read the error more. What version of python are you using?

[gimballock]

Sorry for the delay, Python 3.9.2

[typ-ex]

I think what's happening is that you have the incorrect python compatibility with docker, or at least that is a part of it

Given this ticket, which I'm surprised you didn't get this error

ansible/ansible#60748

Uninstall docker-py, and run pip3 install docker
