Description

Hi All,

Using below given docker-compose.yml, I am able to create devices/services.

Note that mongo container is started before Orion, as Orion needs it
as dependency and reserve the order has been found problematic in some
low resource hosts

Hi Juanjo,

I am stuck and need your help. I have following Docker containers.

ubuntu@ubuntu16:~$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0d342bf05ee8 fiware/iotagent-ul "/bin/sh ~~c 'bin/iot..." 42 minutes ago Up 42 minutes 0.0.0.0:4041~~>4041/tcp, 0.0.0.0:7896->7896/tcp festive_torvalds

0edcd40bfc66 mongo:3.4 "docker-entrypoint.s..." About an hour ago Up 45 minutes 27017/tcp fiware_mongo_1
ubuntu@ubuntu16:~$

I am unable to create/get devices. In logs I found following errors.

I followed below given steps.

1. First I created Orion, Mongo and mosquitto containers using below given docker-compose.yml script.

Note that mongo container is started before Orion, as Orion needs it
as dependency and reserve the order has been found problematic in some
low resource hosts
mongo:
image: mongo:3.4
command: --nojournal

orion:
image: fiware/orion
links:

mongo
ports:
"1026:1026"
command: -dbhost mongo
mosquitto:
image: ansi/mosquitto
ports:
"1883:1883"
expose:
"1883"

2. Then I used below command to install Ultra Light IoT Agent.
docker run -d --link fiware_orion_1 --link fiware_mosquitto_1 --link fiware_mongo_1 -p 7896:7896 -p 4041:4041 fiware/iotagent-ul

Kindly guide what am I doing wrong? It seems that IoTAgent could not connect to Mongo DB but I am not sure what to change, where to change and how? Just FYI, I have Docker Containers on single Ubuntu 16.

Dear Krishan,

Thank you for your interest in FIWARE.

I hope some of my colleagues will come with a detailed answer regarding the issue with FIWARE Lab credentials you raised. I just pretend here to respond some of the other questions.

You don't need to deploy all the GEs you list in order to setup a complete operational "Powered by FIWARE" IoT-enabled platform architecture.

It should be enough to have:

Orion Context Broker (this is the core component you are required to have in a platform to actually claim it is "Powered by FIWARE")
Backend Device Management IDAS - here you have two options:
either some of the already existing IDAS IoT Agents works for your scenarios
or you have to develop a new IoT Agent using the IDAS Framework for development of IDAS IoT Agents

With this approach, it should be enough.

Of course, there are other components of FIWARE you may want to use to configure a more complete "Powered by FIWARE" Smart City platform. As an example, I mention here some examples:

CKAN extensions to support right-time open data: these are a number of plug-ins for CKAN (most widely open data publication platform adopted by many cities worldwide and particularly in Europe) enabling the publication of query resources on the Orion Context Broker as right-time open data resources.
Cygnus, in order to transfer history of Context Data managed by Orion into multiple data sinks (e.g., a Hadoop BigData system to perform bigdata analysis on Context history).
Perseo, in order to perform Complex Event Processing on top of Context data
etc

If you wish, we can setup a confcall so that we can explain to you the reference architecture for "Powered by FIWARE" Smart City platforms and opportunities for collaboration.

Hope it helps,

Cheers,

Juanjo

Hi All,

I am working with FiWare to setup a Smart City project.
As per my understanding so far, we need following GEs (considering minimum requirement)

Orion Context Broker
IoT Broker
Backend Device Management - IDAS
IoT Agent - having python script (At my local machine)

I have following queries so far.

Do let me know what other GEs I need to install?
Can we install all required GEs on same instance (On Fiware cloud)?
Do let me know if I need to follow any particular steps and sequence?
How GEs interconnect with each other? Is there any configuration? E.g. How IoT Broker and Orinon Context Broker communicate?
I am following with https://fiware-orion.readthedocs.io/en/develop/quick_start_guide/index.html. Here what would be the credentials and URL to get the oAUTH token? I am using following with my Fiware LAB account credentials and these are not working.
RESP=`curl -s -d " {\"username\": \"$USER\", \"password\":\"$PASSWORD\"}
" -H "Content-type: application/json" https://orion.lab.fiware.org/token`

After installation of all GEs, I will do following steps. Please correct if I am wrong.
Using IoT Agent python scripts, create required Entities/Models.
Update attributes of the entity
Fetch the entities
Subscriptions

Thanks & Regards,
Krishan Babbar

Dear Krishan,

Thank you for your interest in FIWARE.

I hope some of my colleagues will come with a detailed answer regarding the issue with FIWARE Lab credentials you raised. I just pretend here to respond some of the other questions.

First I created Orion, Mongo and mosquitto containers using below given docker-compose.yml script. Note that mongo container is started before Orion, as Orion needs it as dependency and reserve the order has been found problematic in some low resource hosts mongo: image: mongo:3.4 command: --nojournal orion: image: fiware/orion links: mongo ports: "1026:1026" command: -dbhost mongo mosquitto: image: ansi/mosquitto ports: "1883:1883" expose: "1883" 2. Then I used below command to install Ultra Light IoT Agent. docker run -d --link fiware_orion_1 --link fiware_mosquitto_1 --link fiware_mongo_1 -p 7896:7896 -p 4041:4041 fiware/iotagent-ul Kindly guide what am I doing wrong? It seems that IoTAgent could not connect to Mongo DB but I am not sure what to change, where to change and how? Just FYI, I have Docker Containers on single Ubuntu 16.

I hope some of my colleagues will come with a detailed answer regarding the issue with FIWARE Lab credentials you raised. I just pretend here to respond some of the other questions. You don't need to deploy all the GEs you list in order to setup a complete operational "Powered by FIWARE" IoT-enabled platform architecture. It should be enough to have: Orion Context Broker (this is the core component you are required to have in a platform to actually claim it is "Powered by FIWARE") Backend Device Management IDAS - here you have two options: either some of the already existing IDAS IoT Agents works for your scenarios or you have to develop a new IoT Agent using the IDAS Framework for development of IDAS IoT Agents With this approach, it should be enough. Of course, there are other components of FIWARE you may want to use to configure a more complete "Powered by FIWARE" Smart City platform. As an example, I mention here some examples: CKAN extensions to support right-time open data: these are a number of plug-ins for CKAN (most widely open data publication platform adopted by many cities worldwide and particularly in Europe) enabling the publication of query resources on the Orion Context Broker as right-time open data resources. Cygnus, in order to transfer history of Context Data managed by Orion into multiple data sinks (e.g., a Hadoop BigData system to perform bigdata analysis on Context history). Perseo, in order to perform Complex Event Processing on top of Context data etc If you wish, we can setup a confcall so that we can explain to you the reference architecture for "Powered by FIWARE" Smart City platforms and opportunities for collaboration. Hope it helps, Cheers, Juanjo On 18/01/2018 10:33, Krishan Babbar wrote: Hi All, I am working with FiWare to setup a Smart City project. As per my understanding so far, we need following GEs (considering minimum requirement) Orion Context Broker IoT Broker Backend Device Management - IDAS IoT Agent - having python script (At my local machine) I have following queries so far. Do let me know what other GEs I need to install? Can we install all required GEs on same instance (On Fiware cloud)? Do let me know if I need to follow any particular steps and sequence? How GEs interconnect with each other? Is there any configuration? E.g. How IoT Broker and Orinon Context Broker communicate? I am following with https://fiware-orion.readthedocs.io/en/develop/quick_start_guide/index.html . Here what would be the credentials and URL to get the oAUTH token? I am using following with my Fiware LAB account credentials and these are not working. RESP=`curl -s -d " {\"username\": \"$USER\", \"password\":\"$PASSWORD\"} " -H "Content-type: application/json" https://orion.lab.fiware.org/token ` After installation of all GEs, I will do following steps. Please correct if I am wrong. Using IoT Agent python scripts, create required Entities/Models. Update attributes of the entity Fetch the entities Subscriptions Thanks & Regards, Krishan Babbar ============================================================================================================================ Disclaimer: This message and the information contained herein is proprietary and confidential and subject to the Tech Mahindra policy statement, you may review the policy at http://www.techmahindra.com/Disclaimer.html externally http://tim.techmahindra.com/tim/disclaimer.html internally within TechMahindra. ============================================================================================================================
