.dockerignore

# Syntax
#
# The .dockerignore file is a newline-separated list of patterns similar to the file globs of Unix shells.
# Leading and trailing slashes in ignore patterns are disregarded.
# The following patterns all exclude a file or directory named bar in the subdirectory foo under the root of the build context:
#
#     /foo/bar/
#     /foo/bar
#     foo/bar/
#     foo/bar
#

# ignore the files "Dockerfile" and ".dockerignore", so they cannot be copied to images via "COPY" OR "ADD".
