docker: “build” requires 1 argument

When you  are trying to build a docker image from the docker website, you might encounter following error.

docker build -t dockerTest/redis

docker: "build" requires 1 argument. See 'docker build --help'

This error occurs when you use the Dockerfile in the local directory This error can be avoided by adding a dot in the end as displayed below.

docker build -t dockerTest/redis .

Note that if you using docker 1.5 you can specify a Dockerfile in another place.

docker build -f, --file=""
