# Sample local override file
# Overrides values in `docker-compose.yml`
# Copy to `docker-compose.override.yaml` and customize to use.
# It's `.gitignore`d by default.
# See more at https://docs.docker.com/compose/multiple-compose-files/merge/
# YAML Anchors, Aliases, and Overrides are awesome!
# Anchors (&) are used to define a value.
# Aliases (*) are used to reference a value.
# Overrides (<<:) are used to merge values.
#
# We use them for `base_volumes` in the main compose file.
# Depending on the level of placement, you get different behaviors.
# If you ever want to see the resulting configuration, run:
# docker compose config
# It will spit out a large valid compose yaml to stdout.
# For custom keys outside the Compose schema, prepend an `x-` to the key.
# Override the default command to exit immediately
