fiware / tutorials.getting-started Goto Github PK

I started following this series of tutorials to learn more about NGSI-LD but the link to import the postman collection at the begining has expired.

In the second request (barn creation) of the "Creating Data Entities" section, the option --d has a dash left over. In NGSI-LD branch

According to the tutorial the services script can be used to validate data models:

./services validate [file]

However, services contained in this repo does not know this command:

tutorials.NGSI-LD/tutorials.Getting-Started$ ./services validate
Command not Found.
usage: services [create|orion|scorpio|stellio|stellio|stop]

for instance

docker rmi $(docker images -a -q)

In the architecture section, it speaks that it consists of three elements but four elements are being presented and in the 'tutorial application' element (which would be the fourth), no content appears, unlike the same tutorial in https://ngsi-ld-tutorials.readthedocs.io/en/latest/working-with-%40context.html#ngsi-ld-rules that does have content. In NGSI-LD branch

Hi,
I tried to replace the ngsi-cintext.jsonld file with my own context file. To do this, I replaced the file in the data-models folder. After starting the service, I tried to query this file at http://localhost:3000/data-models/ngsi-context.jsonld. But here I get the file from the FIWARE tutorial and not my own. It is not clear to me where this file comes from or how to include my own file.
Maybe someone can help me to solve this problem.

we want to encourage developers to use GeoJSON. Furthermore, the NGSI-LD standard only allows GeoJSON.

The url https://uri.fiware.org/ns/data-models that is the base for the fiware is not accessible
So the linked data does not work ie.

"fiware": "https://uri.fiware.org/ns/data-models#",
"Building": "fiware:Building",

-> https://uri.fiware.org/ns/data-models#Building

The stoppingContainers function in the services script does not filter based on labels and therefore removes all containers and volumes on the machine.

• https://fiware.github.io/tutorials.Getting-Started/img/fiware.png

In the request of the section "filter context data by querying metadata" the header 'rel="http://www.w3.org/ns/json-ld#context";' is repeated twice, missing even the double closing quotation mark in the first repetition. In NGSI-LD branch

As I've been going through the tutorial (great postman samples btw), I got stuck on how to register an IoT Agent, meaning how do I get/generate tokens etc?

Hi,

I am trying to use the Getting Started guide on the NGSI-LD branch and I have the following error when trying to launch the services:

tutorials.Getting-Started on  NGSI-LD [$]
➜  ./services orion
Stopping containers
Unable to parse logging level: compose

I have the same error when running ./services stop or ./services create.

Any idea?

Yo Jason, here are some initial comments:

• There should be an installation section:

1. had to install virtualbox & docker-machine, in addition to docker itself
2. had to create a default docker machine and connect my shell to the new machine
3. only then was able to pull mongo and orion

• I was not able to connect to orion ("curl: (7) Failed to connect to localhost port 1026: Connection refused"), had to change the command to "curl -X GET http://$(docker-machine ip default):1026/version"

• had to change all the following commands because the localhost or 0.0.0.0 didn't work

• the outputs of GET commands should be in a json format, but shown in the console as plain text. To get the output shown in the tutorial I had to use the following command:
  "curl -X GET http://$(docker-machine ip default):1026/v2/entities/urn:ngsi-ld:Store:001?options=keyValues | python -m json.tool" (this also doesn't work for all GET commands, no idea why)

• my output was not UTF-8, but something like "Bornholmer Stra\u00dfe 65". I didn't bother to change it, but probably this should be mentioned.

• perhaps the parameter/flag -X should be discussed

• for this command: "curl -X GET http://$(docker-machine ip default):1026/v2/entities?type=Store&georel=near;maxDistance:1500&geometry=point&coords=52.5162,13.3777" I get a confusing output:

[1] 3876
[2] 3877
[3] 3878
-bash: maxDistance:1500: command not found
[4] 3880
[2] Done georel=near
[3] Exit 127 maxDistance:1500
[4]+ Done geometry=point
