Task #6068
closedMove redash (lorawan.ungleich.ch) to a new IPv6 only VM in place6
40%
Description
Hey Dongwoo,
this is a great task for practising. It's a lot of small and easy steps to ensure everything works.
When migrating to a new IPv6 only VM, we might need to change our setup from "TTN sends data via http post" to "We poll data from TTN via ? (where ? might be MQTT)"
- Create a new VM
- 10GB SSD, 100 GB HDD
- Setup DNS for the VM: lorawan-dev.ungleich.ch
- Setup redash (can be OS or docker, latter might be easier)
- Setup postgresql
- Setup a new user
- Clone https://code.ungleich.ch/ungleich-public/lorawan/
- Login to https://www.thethingsnetwork.org/ (= TTN)
- Let Nico know which username you have at TTN
- Create a new integration so that you can get the data
- Create a new script similar to ttnv2receiver.py (from https://code.ungleich.ch/ungleich-public/lorawan/) that polls the data and writes it into the database
- Install monit and configure monit to ensure that the script is always working
- Configure redash to use LDAP based login
At this point we should have a full replacement of lorawan.ungleich.ch. Now we make things pretty:
- Put all steps into cdist
- Create a new VM
- Setup DNS lorawan-new.ungleich.ch
- Only run cdist against it
- The new VM should be in the same state as the previous VM
- Delete the previous VM lorawan-dev.ungleich.ch
Now we do the migration:
- Delete database on lorawan-new.ungleich.ch (i.e. make it clean)
- Export old data from lorawan.ungleich.ch to lorawan-new.ungleich.ch
- Ensure that new data is still added on lorawan-new.ungleich.ch
- If everything is good:
- Delete old VM
- Rename new VM in DNS to lorawan.ungleich.ch

Once Redash is installed, the service will be available on your server IP or DNS name assigned. Point your browser to the server address to access it.

Just for clarifcation: is it already up and running?
->Dear, @Nico Schottelius.
No, Not Yet. "docker ps" is showing that it is working, but it's not true.
I'm searching debugging method. I need more understanding about docker.

Hey Dongwoo,
you should not need to force IPv6, as we have outgoing NAT64.
Double check that your IPv6 address is in the NAT64 range, then
everything should work

Thanks @Nico Schottelius,
I checked my VM IP in opennebula.

:= I found that there should be a problem (IPv6 network is not working),
but I can not debug it because I do not know the structure of the Docker.
현재, Nginx Docker Container (ipv4 IP) 에서 외부 lorawan.lab.ungleich.ch 로 연결이 되지 않는다.
VM 이 IPv6 Only 라서 그런 것 같다. docker 내에서 IPv6 사용이 가능하도록 설정이 필요할것 같은데, 방법이을 모르겠다.
또한 도커에서 DNS 설정이 누락되어, apt-get update 시 접속이 되지 않는다.
:= Currently, there is no connection from the Nginx Docker Container (ipv4 IP) to the external lorawan.lab.ungleich.ch. It seems that my VM is IPv6 Only. I think I need to enable IPv6 in the docker, but I do not know how. Also, the DNS configuration is missing from the docker, so it will not be able to connect to HTTP servers for "apt-get update".

Very cool, Dong Woo!
I mentioned to Jason yesterday: the next step is probably to get the data on an IPv6 only VM from https://www.thethingsnetwork.org/ (TTN). For this you will need to create an account there. Afterwards I can grant you access.
As TTN does not support IPv6 for pushing (HTTP POST) messages to us, we will need to pull messages, which will use NAT64. For this I recommened using an MQTT client. You find examples of it in https://code.ungleich.ch/ungleich-public/lorawan.
Updated by Dong Woo Koh about 6 years ago
@Nico Schottelius, I joined TTN.org. with my email, dongwoo.koh@ungleich.ch
Thanks.

I just granted you access - can you check https://console.thethingsnetwork.org/applications/datacenterlight/integrations ?
I think you will need to add a new integration so that you can connect using MQTT

2 hints Dong-Woo:
- Usually data base servers should only listen on ::1 or 127.0.0.1, or even better only on a unix socket. This way you do not need to worry about security
- If opening up the database port, I strongly suggest to use the IPv6 address and not the IPv4 address
To continue, I strongly suggest to try to get the data from TTN in the next step
Updated by Dong Woo Koh about 6 years ago
That's why I use public IP with v4, I could not solve the attached problem with "localhost 127.0.0.1" in redash.
Can you give some advice?
After solving this problem, I'll try to get data from TTN.
Thanks.

It seems that "localhost" is regarded as "localhost" of redash container.

#. Reference
https://github.com/mqtt/mqtt.github.io/wiki
Websocket은 TCP socket과 많이 닮았지만, 차이점도 있다.
그 차이점은 브라우저에서 서버로 양방향 커뮤니케이션 연결을 시도 한다는 점이다.
웹소켓이 위치하면서 웹브라우저에서 웹 어플리케이션을 위한 first class MQTT 지원이 가능해졌습니다.
IBM과 Eurotech(Arcom)에 의해 1999년 최초 개발
센서/장치 + 모바일 기기들의 연결을 위한 프로토콜
MQTT 프로토콜 오픈소스로 공개 (http://www.mqtt.org)
단순하고 미니멀한 Pub/Sub 메시징 체제
– 기업 경계 박의 Edge 네트워크 장치와 기업 내의 백엔드 애플리케이션 간 메시지 교환에 접합
– 간편한 메시징을 위한 직관적 verb set(connect/disconnect publish/subscribe) 제공
오버헤드를 최소화
– 가장 작은 메시지 사이즈는 2byte: 가변길이 MQTT헤더 + 애플리케이션 Payload
– Payload 데이터에 중립적: 별도의 다른 애플리케이션 헤더 불필요
– 클라이언트 라이브러리: C버전은 30KB, Java 버전은 100KB 내외
Pub/Sub에 있어서 메시징 신뢰성을 위한 세가지 QoS(Quality of Service) 레벨 제공
– 반드시 전달되어야하는 중요 메시지에 대한 전달 보장
– QoS 0 : 한 번만 전달하고 전달 여부는 확인하지 않음.
– QoS 1 : 적어도 한 번 이상 전달하고 전달 여부 확인.
– QoS 2 : 4단계의 핸드셰이킹(handshaking)을 통해 정확히 한 번만 전달.

Cool, you ARE receiving data already!
The error you have is because there is no role root in your postgres
database.
I highly suggest to create a new user, "app", create a role for it and
then use this user instead of root.

Marc, this task is interesting for you to watch. Dong Woo has gotten the MQTT part up and running.
Dong Woo, Marc, I suggest that you ping each other in the infrastructure channel and exchange your experiences!

Note: the location is always the location of the gateway, not of the device.

I'll follow your suggestion.

It took a long time because I could not solve the minor problem in controlling the DBMS (I forgot much memories related DBMS. I did work again in 20 years.^^).
After rearranging my results in PPT, I'll share all procedure in brandnewchat with a few pictures.
