# One-time migration overlay for installations that used Hollo's former MinIO
# Compose setup.  New installations and normal operation do not need this file.
#
# Run it from the directory and with the Compose project name used by the old
# installation:
#
# docker compose -f compose.yaml -f compose.migrate-minio.yaml \
#   --profile migrate-minio run --rm migrate-minio
# docker compose -f compose.yaml -f compose.migrate-minio.yaml \
#   --profile migrate-minio run --rm verify-minio-migration
#
# After verification, stop the temporary services without deleting volumes:
#
# docker compose -f compose.yaml -f compose.migrate-minio.yaml \
#   --profile migrate-minio down
#
# Never add `-v` to the `down` command.  It would delete the old MinIO media
# volume and the new RustFS volume.  See the Docker installation guide for the
# complete procedure: https://docs.hollo.social/install/docker/#migrating-from-minio
