# syntax=docker/dockerfile:1

# This Dockerfile is used to build Teleport on ARM (32-bit) only.
# The binaries produced need to be able to run on all the linux
# distributions we support. See https://goteleport.com/docs/installation/
# The binaries also run in the OCI containers we produce,
# both "heavy" and distroless.
