#FROM python:3.7.3-alpine
FROM python:3.7.3-slim-stretch
# The tool to run both "gunicorn" and "Celery" would be "supervisor". An example in:
# https://github.com/pm990320/docker-flask-celery
#
# 1) Build:
# docker build -t magicnexush2020/magic-nis-backend .
#
# 1.bis) REFRESH image into Docker Hub:
# ("docker login" first)
# docker push magicnexush2020/magic-nis-backend:<TAGNAME>
#
# Usage example:
# 2) Create (using a configuration file)
# docker create --name nis-local -p 8080:80 -e MAGIC_NIS_SERVICE_CONFIG_FILE="nis_docker_naples.conf" magicnexush2020/magic-nis-backend:latest
# 2) Create (using autogenerated configuration). NO NEED FOR STEP 3.
# docker create --name nis-local -p 8080:80 magicnexush2020/magic-nis-backend:latest
# 2) Create, run and remove on exit, using autogenerated configuration (NO NEED FOR STEPS 3, 4)
# docker run --rm -p 8085:80 magicnexush2020/magic-nis-backend:latest
#
# 3) docker cp nis_docker_naples.conf /app/nexinfosys/restful_service/nis_docker_naples.conf
#
# 4) docker start nis-local && docker logs nis-local -f
#
#
# LOCAL SERVER: (the configuration uses REDISLITE, so no need to have a REDIS instance) the image would be:
#
# docker create --name nis-local -p 8080:80
# -v /home/rnebot/DATOS/docker/nis-local:/srv
# -e MAGIC_NIS_SERVICE_CONFIG_FILE="nis_docker_local_sqlite.conf" magic-nis:latest
# docker cp nis_docker_local_sqlite.conf /app/backend/restful_service/nis_docker_local_sqlite.conf
#
#
# NOTE: in the example, the host directory (/home/rnebot/DATOS/docker/nis-local) must have RWX permissions
# for all users: chmod rwx+o ...
# If not, it may not be possible to create
#
# PRODUCTION SERVER (MAGIC server provided by UniNa -Naples-):
#
# docker create --name nis-local --network=magic-net -l magic-postgis -l magic-redis -v /srv/docker/magic/data/nis:/srv
# -e VIRTUAL_HOST=one.nis.magic-nexus.eu -e VIRTUAL_PORT=80 -e LETSENCRYPT_HOST=one.nis.magic-nexus.eu
# -e LETSENCRYPT_EMAIL=<email address> -e MAGIC_NIS_SERVICE_CONFIG_FILE="nis_docker_naples.conf"
# -e MOD_WSGI_REQUEST_TIMEOUT=1500 -e MOD_WSGI_SOCKET_TIMEOUT=1500
# magic-nis:latest
#
# docker cp nis_docker_naples.conf /app/backend/restful_service/nis_docker_naples.conf
