3Jenkins Build Images

whats issue we facing please give any idea to solve this issue

docker build -t stregi01.stratos.xfusioncorp.com:5000/nginx:latest.
“docker build” requires exactly 1 argument.

docker build expects directory containing Dockerfile as argument
I. e. docker build -t stregi01.stratos.xfusioncorp.com:5000/nginx:latest .
you are missing a space before the last dot on the command line

thanks solve issue now
