#EXAMPLE docker commands build and tag
#docker build .
#docker build ---- use buildDocker.sh shell ----
#docker tag k8svisual/vpk:latest  k8svisual/vpk:6.1.0
#docker push k8svisual/vpk:6.1.0

#EXAMPLE docker command to run VpK and map volume and port
#docker run -v /Users/bob/snaptest/:/vpk/cluster -p 4500:4200 k8svisual/vpk

#EXAMPLE docker command to open shell via exec
# docker ps
# copy k8svisual/vpk CONTAINER ID to clip board
#docker exec -it (paste Containe ID) sh

#EXAMPLE docker command to run command in vpk container
#docker run -it k8svisual/vpk sh

#======================= Multi-platform docker images =========================
#
# List existing builds

#
# Create a New Builder Instance:
# Docker buildx operates with the concept of "builders", which are essentially 
# environments where the build process runs. Create a new builder instance 
# which has support for multi-architecture builds:
#
#    docker buildx create --name mybuilder --use
#
# Start up the Builder: 
# After creating a builder, you need to start it:
#
#    docker buildx inspect --bootstrap
#
# Build the image:
# Now, use the docker buildx build command to build the image for multiple 
# architectures. You need to specify each architecture with the --platform 
# flag. For example, to build for arm64 and amd64:
#
#    docker buildx build --platform linux/amd64,linux/arm64 -t k8svisual/vpk:latest . --push
#
# Verify the Image:
#
#    docker manifest inspect k8svisual/vpk:latest
#
