# TFLM CI Docker Container
#
# This container includes all dependencies for TFLM CI checks and is
# recommended for local debugging to ensure a consistent environment.
#
# === Usage ===
#
# --- Pull a prebuilt image ---
# See all versions: https://github.com/users/TFLM-bot/packages/container/tflm-ci/versions
#   docker pull ghcr.io/tflm-bot/tflm-ci:<version>
#
# --- Build locally ---
# (Run from the root of the TFLM repository)
#   docker build -f ci/Dockerfile.micro -t tflm-ci .
#
# --- Build and upload to GHCR.IO ---
# (Run from the root of the TFLM repository)
#   export TFLM_CI_VERSION=0.6.7
#   docker build --no-cache -f ci/Dockerfile.micro -t ghcr.io/tflm-bot/tflm-ci:$TFLM_CI_VERSION .
#   docker push ghcr.io/tflm-bot/tflm-ci:$TFLM_CI_VERSION
#
# --- Run locally for debugging ---
# (Mounts local repo and opens a shell)
# (Run from the root of the TFLM repository)
#   docker run -it --rm -v $(pwd):/opt/tflm -w /opt/tflm tflm-ci /bin/bash
