local.Dockerfile

# Builds images used by the bridge using locally built binaries.
#
# In particular, it can be used to build Substrate nodes and bridge relayers. The binary that gets
# built can be specified with the `PROJECT` build-arg. For example, to build the `substrate-relay`
# you would do the following:
#
# `docker build . -f local.Dockerfile -t local/substrate-relay --build-arg=PROJECT=substrate-relay`
#
# See the `deployments/README.md` for all the available `PROJECT` values.
#
# You may use `scripts/build-containers.sh` to build all binaries and images at once.

# This image needs to be binary compatible with the host machine (where images are built).
