QUESTION
I've created a doorbell system (server, client) for my home which works via MQTT publish/subscriptions to know when someone rang the doorbell. It works quite well, however in my client, the MQTT connection keeps closing, even after setting _client->setAutoKeepAlive(true).
Moreover, I want to know if anyone can give me a hint on how to set the app to keep running in the background. What I found out so far is that I can set the persistence attribute in my AndroidManifest.xml, but is that all I can do to have my application run in background all the time, even if it gets closed accidentally?
My questions:
- How can I prevent
QMqttClientfrom automatically disconnecting - or: how can I automatically reconnect if the connection gets lost? - How do I prevent Qt Android apps from being killed?
ANSWER
Answered 2021-Nov-10 at 10:37You can use the service to avoid program destruction as much as possible.
A Service is an application component that can perform long-running operations in the background. It does not provide a user interface. Once started, a service might continue running for some time, even after the user switches to another application. Additionally, a component can bind to a service to interact with it and even perform interprocess communication (IPC). For example, a service can handle network transactions, play music, perform file I/O, or interact with a content provider, all from the background.
The Android system stops a service only when memory is low and it must recover system resources for the activity that has user focus. If the service is bound to an activity that has user focus, it's less likely to be killed; if the service is declared to run in the foreground, it's rarely killed. If the service is started and is long-running, the system lowers its position in the list of background tasks over time, and the service becomes highly susceptible to killing—if your service is started, you must design it to gracefully handle restarts by the system.

QUESTION
I have a traefik environment running in docker. Originally I was running services in standard containers. I am not deploying containers to docker swarm and I have done this for traefik too, where the container is only deployed to my swarm manager.
For some reason, traefik successfully registers the host name I have given it, and can access that fine. However, when I deploy any other service to the swarm, traefik doesn't pick it up. There is one other service that has partially worked. I have deployed heimdall to docker swarm which can be access from gateway.docker.swarm:8091 but I don't want the port either.
My traefik compose file is as follows:
...ANSWER
Answered 2021-Jan-12 at 13:50I have figured out the problem.
In my compose file, I was using "traefik.http.services.heimdall.loadbalancer.entrypoints=http" as well as "traefik.http.routers.heimdall.entrypoints=http"
this was incorrect and needed to just be "traefik.http.routers.heimdall.entrypoints=http"
For heimdall, I was also targetting the external port of 8091, whereas I actually needed to target the internal port of 80
QUESTION
I have an environment running docker containers. This environment hosts Traefik, Nextcloud, MotionEye and Heimdall. I also have another environment running CoreDNS in a docker container. For some reason, I can get MotionEye to be accessible from motioneye.docker.swarm (changed the domain in here for privacy). However, for nextcloud and Heimdall, I have to explicitly access the ports and I'm struggling to tell why. e.g. Heimdall is gateway.docker.swarm:8091 when should be gateway.docker.swarm
When a user requests a webpage onto the local dns server X.X.X.117 it gets routed through to the traefik instance on X.X.X.106.
My traefik compose file is as follows:

Answered 2021-Jan-02 at 21:15When you access through gateway.docker.swarm:8091 it works because you are accessing the heimdall container directly. This is possible because you defined
QUESTION
I have traefik (v. 2.3.5) and other services running on my raspberrypi in my home network. Each service is running on a different port on the same machine. I want traefik to redirect a call from a subpath to a different url. Like so:
http://myServer/omv --> http://myServer:8000
http://myServer/heimdall --> http://myServer:8003
However I can not make it work. My router is not offering a domain/subdomains so I have to live with subpathes instead.
OMV is installed locally so I have created a file provider and that is the only one that is working. I cannot find out what I'm doing wrong with my docker-compose files for e.g. heimdall.
Here is the traefik docker-compose.yml:

...ANSWER
Answered 2020-Sep-04 at 19:00You just need a way to identify what goes in each section.
This particular way is quite inefficient because it runs through each item in the runesArray for each section but you can visualize what is going on and then work on your data.

Im using react like this
Firstly I load the store with mapStateToProps. And inside that function im actually able to read the store. The object that is read there is basically the same as the this.state.renderedEl , but with different values.
My goal is to delete that state, and use the store values instead.
Those values should be read in the render() where Im actually using the this.state.renderedEl values to evaluate some conditions. But I dont undestand how to read the store values instead

First of all, ive read this question React-redux connect() cannot wrap component defined as a class extending React.Component But im still unable to uderstand it since the connect is being done in some kind of upper level, but I dont understand that phase.

Answered 2020-Apr-23 at 11:26do only export class SideBar [...] for testing purposes, but export default connect(mapStateToProps)(SideBar) which connects your component to redux state and assigns reduced state to props.
