dbt-core Docker & Self-Hosted Deployment

# Self-hosted dbt docs server.
#
# Point DBT_TARGET_PATH at a project's `target/` dir containing
# target/index/*.parquet (from `dbt --write-index <run|build|compile>`), then
# open http://localhost:8580. Use an absolute path — relative resolves against
# this file's dir.
#
#   DBT_TARGET_PATH=/abs/path/to/project/target docker compose up --build
#
# The image tracks the newest dbt release carrying a Linux binary. Pin one with
# DBT_VERSION=2.0.0-beta.2 (and see the note in the Dockerfile about build
# caching: `--build-arg`/`--no-cache` is what re-resolves `latest`).
