Support for Docker and Podman build on mac silicon (ARM)

[zubcevic]

This makes it possible to run the container builds on MacOS with silicon chips as well as other platforms that have either podman or docker installed.

To use:
unchanged: ./mvnw clean install -PbuildDocker

or if you prefer podman:
./mvnw clean install -PbuildDocker -Dcontainer.executable=podman

Hi @zubcevic

I recovered these changes. Building docker image on my Intel Macbook and Docker Machine is working.
But I've got the follwing error while starting the discovery-server

arey:~$docker-compose up                 
grafana-server is up-to-date
prometheus-server is up-to-date
config-server is up-to-date
tracing-server is up-to-date
Starting discovery-server ... error

ERROR: for discovery-server  Cannot start service discovery-server: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "./dockerize": stat ./dockerize: no such file or directory: unknown

Do you have any idea?

Image build is successful with the exec-maven-plugin:

mvn clean install -P buildDocker -X

With the docker images command line I detect my local Docker image has not been build.

If I return to the docker-maven-plugin build I can see the image hash and the image tag:

$docker --version

Maybe adding a --load flag

arey:~$docker build -f ../docker/Dockerfile --load --build-arg ARTIFACT_NAME=spring-petclinic-discovery-server-3.0.9 --build-arg EXPOSED_PORT=8761 --build-arg DOCKERIZE_VERSION=v0.6.1 -t springcommunity/spring-petclinic-discovery-server /Users/arey/Dev/GitHub/spring-petclinic/spring-petclinic-microservices/spring-petclinic-discovery-server/target
