##################

# No S6_* tuning here : the upstream image is a plain python:slim image with no
# s6-overlay, so the vars the other addons set would be read by nobody

##################
# 3 Install apps #
##################

# Add rootfs
# Absolute paths on purpose : the upstream image sets WORKDIR /app, so the
# relative "find ." used by the other addons would miss /etc entirely

################
# 4 Entrypoint #
################

# The upstream image has no s6-overlay, so ha_entrypoint runs as pid 1 : it
# executes /etc/cont-init.d, then supervises /etc/services.d. This replaces the
# upstream ENTRYPOINT (/app/entrypoint.sh), which is called again from
# rootfs/etc/services.d/kapowarr/run so its PUID/PGID handling is kept
COPY ha_entrypoint.sh /ha_entrypoint.sh
RUN chmod 777 /ha_entrypoint.sh
ENTRYPOINT ["/ha_entrypoint.sh"]

# Install bashio
COPY bashio-standalone.sh /usr/local/lib/bashio-standalone.sh
