# This action is used for building websoft9 docker images to DockerHub at one time
# This action is also release Media and Libarary with build apphub image

# It need LABEL version="" at your dockerfile. And it can divide version. e.g version v3.4.0.3 will divide to latest,v3,v3.4,v3.4.0,v3.4.0.3
# When version include "-", it not divide version and build ony one test image
# It have enable multiPlatform, you add more platform at platform: linux/amd64...
# If you add more paths for trigger, please update app_list= at set-matrix for it also
# MEDIA_FROM environment: source | artifact, when use source get from contentful and oss, use artifact download media-latest from Websoft9 artifact
