You can build an image locally as:
cd /path/to/image/dir
docker build .
where /path/to/image/dir
is any image sub-directory in this directory that contains a
'Dockerfile'.
To build all images on container builder, run:
./build_on_container_builder.sh
Note that your checkout needs to be on the latest deployed commit.
You also need to have access to the clusterfuzz-images
project.
