func ReadDockerIgnore ¶

func ReadDockerIgnore(contextDir string) ([]string, error)

ReadDockerIgnore reads a .dockerignore file in `contextDir` and returns the list of file patterns to ignore. Note this will trim whitespace from each line as well as use GO's "clean" func to get the shortest/cleanest path for each.
