{color: red}Please, ANSWER this question AT{color} https://stackoverflow.com/questions/53654763/do-i-need-any-proxy-to-make-context-provider-visible-by-fiware-orion-context-bro
+Question:+
Do I need any proxy to make Context Provider visible by FIWARE Orion Context Broker?
+Description:+
I cannot get an attribute from registered Context Provider in Orion Context Broker installed from docker. Do I need something more (e.g. special context proxy?)
SETUP
I have whole Orion Context Broker all setup and running after following this commands:
docker pull mongo:3.6
docker pull fiware/orion
docker network create fiware_default
docker run -d --name=mongo-db --network=fiware_default \
--expose=27017 mongo:3.6 --bind_ip_all --smallfiles
docker run -d --name fiware-orion -h orion --network=fiware_default \
-p 1026:1026 fiware/orion -dbhost mongo-db
ENTITIES
I also added one Store entity (from https://github.com/Fiware/tutorials.Getting-Started tutorial) by running:
curl -iX POST \
'http://localhost:1026/v2/entities' \
-H 'Content-Type: application/json' \
-d '
{
"id": "urn:ngsi-ld:Store:001",
"type": "Store",
"address": {
"type": "PostalAddress",
"value": {
"streetAddress": "Bornholmer Straße 65",
"addressRegion": "Berlin",
"addressLocality": "Prenzlauer Berg",
"postalCode": "10439"
}
},
"location": {
"type": "geo:json",
"value": {
"type": "Point",
"coordinates": [13.3986, 52.5547]
}
},
"name": {
"type": "Text",
"value": "Bösebrücke Einkauf"
}
}'
Moreover I also successfully registered my Context Provider:
curl -iX POST 'http://localhost:1026/v2/registrations' -H 'Content-Type: application/json' -d '{
"description": "Temperature Provider",
"dataProvided": {
"entities": [
{
"id": "urn:ngsi-ld:Store:001",
"type": "Store"
}
],
"attrs": [
"temperature"
]
},
"provider": {
"http": {
"url": "http://192.168.xxx.xxx:8080/temperature"
},
"legacyForwarding": true
}
}'
CONTEXT PROVIDER
I exposed locally my Context Provider (exposed by my SpringBoot application written in Java 10) at http://192.168.xxx.xxx:8080/temperature. The JSON data (returned in html body) is in NSGI v1 format and looks like that:
{
"contextResponses": [
{
"contextElement": {
"attributes": [
{
"name": "temperature",
"type": "float",
"value": "16"
}
],
"id": "urn:ngsi-ld:Store:001",
"isPattern": "false",
"type": "Store"
},
"statusCode": {
"code": "200",
"reasonPhrase": "OK"
}
}
]
}
PROBLEM
When I try to get other entity's attributes (like name) it works fine, but when I try to get temperature attribute with this query:
curl -X GET 'http://192.168.xxx.xxx:1026/v2/entities/urn:ngsi-ld:Store:001/attrs/temperature/value'
I get the following error:
{"error":"NotFound","description":"The entity does not have such an attribute"}
Logs in the Context Broker docker:

Do I need something more in my setup to make this Context Provider work (e.g. special context proxy)?
