Cannot reuse volume if container is run by a different user

$ VOLUME_DIR=`mktemp -d --tmpdir pg-data.XXXXX | tee >(xargs chmod a+rwx)`
$ echo $VOLUME_DIR 
/tmp/pg-data.26hxm

$ docker run --rm -u 12345 -v ${VOLUME_DIR}:/var/lib/pgsql/data -e POSTGRESQL_USER=u -e POSTGRESQL_PASSWORD=p -e POSTGRESQL_DATABASE=db openshift/postgresql-92-centos7

How do file and dir permissions look like depending on how we layout our Dockerfile?

RUN yum install first, COPY contrib next (#57):

$ ls -la /var/lib/pgsql/
total 48
drwxrwxrwx.  4 postgres postgres 4096 Aug 27 12:35 .
drwxr-xr-x. 12 root     root     4096 Aug 26 14:43 ..
drwxrwxrwx.  3 root     root     4096 Aug 26 14:43 .pki

Usage

1. Run collectwords.py with file paths as arguments to build a database of words.
2. Run spellcheck.py to mark misspells.
3. Use sqlite3 shell or anything else to output misspelled words to a file.
4. Go through the file eliminating false positives.
5. Search through the codebase and fix typo by typo :-)
