Update linux command in pushing.md to use docker daemon inside minikube

[amigueldiez]

Description of change

This update corrects a command in the documentation related to using the Docker daemon with Minikube. The previous command was invalid, and it has been replaced with the correct one that properly connects to Minikube's Docker daemon.

Details

By running the following command in the terminal:

$ minikube docker-env

The output is:

export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.67.2:2376"
export DOCKER_CERT_PATH="/home/XXX/.minikube/certs"
export MINIKUBE_ACTIVE_DOCKERD="minikube"

# To point your shell to minikube's docker-daemon, run:
# eval $(minikube -p minikube docker-env)

The command shown at the end (eval $(minikube -p minikube docker-env)) is the one that works and should be used, whereas the one previously found in the documentation is incorrect. This update replaces the invalid command with the correct one.

Hi @amigueldiez. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

The previous command was invalid

minikube docker-env is a completely fine command, the command you replaced it with is just explicitly setting the profile flag, but if you don't supply the -p command it does -p minikube automatically (assuming you don't have a different profile set with minikube profile <profile>.
