I am following this blog to deploy MongoDB in GKE and I came to a point where I need to connect my Loopback-API image in different pod but the same cluster to talk to the database.
Since the local development works as aspected with this datasource.json as following:
{
"db": {
"host": "database",
"port": 27017,
"url": "",
"database": "test",
"password": "",
"name": "mongoDS",
"user": "",
"connector": "mongodb"
}
}
In the tutorial, it is written that, the connection string URI would be:
“mongodb://mongo-0.mongo,mongo-1.mongo,mongo-2.mongo:27017/dbname_?”I am not sure how to implement it to the above datasource.json. Any help will be appreciated.
First, in Loopback's datasource, the name attribute is the same as the key of datasource. Second, the host attribute ought to be the name of pod that contains mongo DB.
The tutorial creates a headless service with the name "mongo" in the default ns.
Replace your "host": "database" with "host": "mongo" in your pod's datasource.json.
