Changing the MongoDB Connection Used by Fiware/Orion

The reference manual is here. I wonder why the official Fiware manual is hard to find on Google.

• Docker - FIWARE-Orion https://fiware-orion.letsfiware.jp/user/docker/

2A. When MongoDB is on localhost

To do this, run this command.

 sudo docker run -d --name orion1 -p 1026:1026 fiware/orion

Verify everything is working.

 curl localhost:1026/version

2B. When MongoDB is running in another Docker container

If you want to run MongoDB in another container, you can start it as follows:

 sudo docker run --name mongodb -d mongo:4.4

Then run Orion with this command:

 sudo docker run -d --name orion1 --link mongodb:mongodb -p 1026:1026 fiware/orion -dbhost mongodb

Verify everything is working.

 curl localhost:1026/version

This method is functionally equivalent to what was described in section 1, but manually performs the steps rather than using a docker-compose file. Data will be lost as soon as the MongoDB container is disabled.

2C. When MongoDB is running on a different host

To connect to a different MongoDB instance, run the following command instead of the previous command:

 sudo docker run -d --name orion1 -p 1026:1026 fiware/orion -dbhost <MongoDB Host>

Verify everything is working.

 curl localhost:1026/version
