[yocto] [layerindex-web][PATCH 1/6] Add docker-compose file to create full layerindex stack of MariaDB, RabbitMQ and Nginx
Konrad Scherer

Tue Jun 26 10:41:30 PDT 2018
Lots of new features added:
- Layerindex runs as unprivileged user inside container
- Celery worker is started before gunicorn
- Entrypoint script supports changing RabbitMQ location
- Entrypoint script support initialization of database and superuser
- Reverse Proxy uses https with self signed certs by default and
supports Let's Encrypt certs (not enabled by default)
- Move docker image to debian stretch and python3
- Remove build tools after installation to reduce the image
to under 500MB in size

+# Layerindex Docker images
+
+The layerindex depends on several pieces of software:
+
+- A database such as mariadb
+- RabbitMQ as a task queue for Celery
+- A reverse proxy such as Nginx for performance
+
+The docker-compose.yaml file will start up a full stack of the 4
+containers necessary to simulate a full production system on a single
+machine using docker-compose.
+
+ > docker-compose up --abort-on-container-exit
+ > docker-compose rm --force -v

+# Building the layerindex image
+
+ > docker build -t yocto/layerindex-app .
+
+# Manual creation of the database
+
+Start a database server. We use MariaDB in production. See
+docker/mariadb_settings.py for an example settings required to connect
+to Mariadb and RabbitMQ
+
+If you have a copy of the the production data now is the time to insert it.
+If not you can skip the next step for a clean install.
