minikube kompose can't push docker image

Question

I made a docker-compose service and it work correctly.

I install minikube and I can access it throw web interface http://127.0.0.1:35591/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/#/overview?namespace=default

But when i try to do a "kompose up" on my docker folder it failed, see under.

It seems that kompose try to push on docker.io instead of my local minikube ?!

How configure kompose to push on my local minikube ?

Try 1 : eval $(minikube docker-env) - Failed

I don't understood, are you trying to push image do minikube? Do you have a private registry installed on minikube? — Mr.KoopaKiller
No I don't, it's my first try, tutorial don't speak about this ? I found this : github.com/kubernetes/minikube/issues/321 it may help ? — WCdr
Please share the link of the tutorial you are following. You need a registry to push/pull the images, as I can see in your log, kompose is trying to push your image to docker.io (default). — Mr.KoopaKiller

I guess you are trying to execute compose command to up your services in minikube.If thats the case, execute this command

eval $(minikube docker-env)

This will set the docker to minikube environment.Then execute the required docker command.

Run eval $(minikube docker-env) on each terminal you want to use, as it only sets the environment variables for the current shell session. Hope this helps.
