# This is the migration makefile.
#
# WHAT IS NEEDED FOR THE MIGRATION:
#
# - $(SQLDB): a dump of the SQL database (format: login password domain)
# - $(OLDBINDDIR): directory with old Bind9 zone files
#
# HOW MIGRATION WORKS, STEP BY STEP (`migration` rule):
#
# 1. build-client -> build bin/dnsmanager-client
# 2. migration-file -> generate $(MIGRATION_FILE_TARGET)
# 3. run-migration-client -> create users and attribute domains
# 4. run-client-genzones -> generate Bind9 zone files with dnsmanagerd
# those files will (mostly) be replaced by the old migrated Bind9 zone files
# 5. copy-old-zones -> copies the old Bind9 zone files where dnsmanagerd just produced its Bind9 zone files
#
# AFTER THE `migration` RULE: `powerdns-add-zones` as root
# This will run `pdns_control bind-add-zone domain zonefile` for every zone file in $(POWERDNS_ZONEDIR).
# Then the different zones should be served by powerdns.
# Migration input file, format: login password domain
SQLDB ?= /tmp/usrdb
# Migration final file format: nb-domains <TAB> login <TAB> domain1 <TAB> domain2 <TAB> domain3
MIGRATION_FILE_TARGET ?= /tmp/dnsmanagerd-migration
# Old Bind9 migrated files.
OLDBINDDIR ?= /tmp/rndczones
# Directory where Bind9 zone files are generated by dnsmanagerd.
BINDDIR ?= /tmp/DATA-dnsmanagerd/bind9-zones
# Where powerdns reads Bind9 zone files.
POWERDNS_ZONEDIR ?= /var/powerdns
