Realm Object Server Docker-Ready // M17

This is the very first version of our Realm Object Server test on Docker. We are open to receive any feedback to improve the codebase.

This aims to be a quick way to start using Realm Object Server with docker. ROS requires private and public key to startup, and a valid configuration file.

With this image we are providing a basic configuration file, which will be used in case you don't provide anything. We also generate on the fly the required private and public keys, and we convert them to the PEM format so Realm can use them properly.

Volumes

This image requires you to mount essentially two volumes:

1. /path/to/your/keys/folder:/realm-keys
2. /path/to/your/config/folder:/etc/realm

Examples

To start docker image, use the command below
replacing path with your properly values.

docker run -d -v /path/to/your/config/folder:/etc/realm -v /path/to/your/keys/folder:/realm-keys -p 9080:9080 molo17srl/realm-object-server:latest

Private and public keys are always re-generated and they're stored to mounted volumes to be compliant with security standard rules.

TODO:

• Add environment variable to force delete of keys and configuration
• Insert envsubst or rb script to replace variables inside yml file
• Add environment variables to replace content of realm-configuration.yml

RancherOS Configurations

Tested with RancherOS, works succesfully behind Load Balancer which expose port 9080 to the world (or just access the 9080 via container address).
