SERVER_VERSION=$(docker version -f "{{.Server.Version}}")
SERVER_VERSION_MAJOR=$(echo "$SERVER_VERSION"| cut -d'.' -f 1)
SERVER_VERSION_MINOR=$(echo "$SERVER_VERSION"| cut -d'.' -f 2)
SERVER_VERSION_BUILD=$(echo "$SERVER_VERSION"| cut -d'.' -f 3)

if [ "${SERVER_VERSION_MAJOR}" -ge 19 ] && \
   [ "${SERVER_VERSION_MINOR}" -ge 0 ]  && \
   [ "${SERVER_VERSION_BUILD}" -ge 3 ]; then
    echo "Docker version >= 19.0.3 it's ok"
else
    echo "Docker version less than 19.0.3 can't continue"
    exit 1
fi

When the script is starting, warn the user if they do not have the minimum docker version (as specified: https://docs.docker.com/compose/compose-file/compose-versioning/ ) of 18.02.0+
