Beware of the plural in ...-registries! This is because this key takes an array as a value:

cat > /etc/docker/daemon.json <<EOF { "storage-driver": "overlay", "insecure-registries": ["hub.sudhaker.com:5000"] } EOF systemctl daemon-reload systemctl restart docker docker info | grep -B1 hub.sudhaker.com Insecure Registries: hub.sudhaker.com:5000
