# Container artifact for the PostgreSQL module

# This should probably rather be something like...:
# FROM registry.fedoraproject.org/module-base-runtime:26
# ...and probably would:
# - contain microdnf rather than dnf
# - not have any repositories configured
# - need a shared-userspace module repo enabled
FROM registry.fedoraproject.org/fedora:26

# PostgreSQL container image
# Exposed ports:
#  * 5432/tcp - postgres
# Volumes:
#  * /var/lib/psql/data - Database cluster for PostgreSQL
