# Container artifact for the PostgreSQL module

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

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

# Install the postgresql server component.

# This image must forever use UID 26 for postgres user so our volumes are
# safe in the future. This should *never* change, the last test is there
# to make sure of that.

# Notes about the below:
# - first sed cmd: don't ask
# - rpm -e ... microdnf install systemd: workaround to missing
#   microdnf downgrade/distro-sync
# - Update packages so everything available is current
# - Need to have charset files, disable normal repo(s), enable module repo(s)
# ORCHESTRATION:
# - Newer versions of the shared-userspace module are supposed to have
#   findutils, not there yet
# - gettext: /usr/bin/envsubst
# - no working python module yet
