I have situation where I want to create large number of entities on orion. I am using docker version of Orion and mongo with this docker-compose.
version: "3"
services:
mongo:
image: mongo:3.4
volumes:
- /data/docker-mongo/db:/data/db
- /data/docker-mongo/log/mongodb.log:/var/log/mongodb/mongod.log
command: --nojournal
orion:
image: fiware/orion
volumes:
- /data/docker-mongo/log/contextBroker.log:/tmp/contextBroker.log
links:
- mongo
ports:
- "1026:1026"
command: -dbhost mongo
Now problems happens when I want to upload 2000 entities (opening new connection for each, I know it can be done different but for now this is request), I successfully create no more than 600 (or less never exact number) of them rest fail to create with error:
"error": {
"errno": "ECONNRESET",
"code": "ECONNRESET",
"syscall": "read"
},
So I assume this issue has something to do with maxConnections, reqPoolSize etc settings in Orion. But in docker I failed to locate Orion config file, I have no way of knowing when I type commands like contextBroker -maxConnections 123456 that setting is being accepted by Orion and docker container.
Also log of Orion is empty, and i cannot determined what is causing this issue when Orion is running on docker.
So main questions:
- Can Orion running on docker be used in same manner as Orion running on VM (are there some fallbacks)
- And how do I check this problem when Orion is running in docker, because I read a lot of docs/issues but no luck (or I missed something).
If you have some advice/soultion it would really help. Thanks

I am using request promise library for making calls, i try others they had same issue. Now since i cannot send u all 2000 responses i will try to describe. So it when i start to send this it behave. It create like 30 entities then next few or more return response saying ECONNRESET then it start creating again and so on.
What confuse me is that it is not failing totally meaning it works but not as intended. Also it seem that Orion close socket or hang it up some period then he is open again and create as normal and so on. If u need any more info ask, and thanks for quick answer.
