## .dockerignore
If a file named `.dockerignore` exists in the source repository, then it
is interpreted as a newline-separated list of exclusion patterns.
Exclusion patterns match files or directories relative to the source repository
that will be excluded from the context. Globbing is done using Go's
[filepath.Match](http://golang.org/pkg/path/filepath#Match) rules.
The following example shows the use of the `.dockerignore` file to exclude the
`.git` directory from the context. Its effect can be seen in the changed size of
the uploaded context.
