# Automatically build multi-architectural tagged container images and push them to DockerHub

# - targeted platforms: x86_64, PowerPC64, ARM64
# - master is built as fnndsc/pl-covidnet-pdfgeneration:latest
# - tagged commits are built as fnndsc/pl-covidnet-pdfgeneration:<tag>
# - tagged commits are also uploaded to chrisstore.co
