I'm running Docker from minikube (and also tried a remote docker machine).

The docker daemon endpoint and cert are configured via env vars:

DOCKER_BUILDKIT=1
DOCKER_CERT_PATH=/Users/rayt/.minikube/certs
DOCKER_HOST=tcp://192.168.64.2:2376
DOCKER_TLS_VERIFY=1

When I run ./mvnw spring-boot:build-image, the container build failed:

...

The plugin assumes the docker daemon is running on localhost:2376, when it the env var DOCKER_HOST is pointing else where tcp://192.168.64.2:2376
