MyController 2.0 is ready for testing

@j54n1n sorry for the delayed response.
Actually you are accessing the storage data directly. Those data will be loaded at startup. and overwritten from memory on an interval mentioned on the mycontorller.yaml file.

It is a Yaml list, you can configure any number of gateways on that file, file name should be as gateway__1.yaml

You can omit state, modifiedon, lasttransaction fields.

Please note: as this is storage schema (not exposed to end user directly), can be change in the future release. It may be an extra work for you, in case if there is a change in the future.

@jkandasa ok, thanks for your info on that topic.

So maybe could there be in the future a more official way to script this? You mentioned for example in the Github issue from MyController v2 some form of scripting.

Or maybe going back to the v1 approach of a backup file or something like that?

Kind regards

So maybe could there be in the future a more official way to script this?

Possible options,

keep a backup and restore from that backup.
In the future I will show an example to add/modify a resource via API

You mentioned for example in the Github issue from MyController v2 some form of scripting.

I mentioned the script to convert the received values with specified math. script result supplied to the MyController.

Or maybe going back to the v1 approach of a backup file or something like that?

We have backup/restore option, in V2 it is possible to backup/restore to different databases (except metrics)

Hello @jkandasa
Today in the morning at startup of my Raspberry Pi I got a crash about concurrent map read/write in one of the goroutines. See also the file dump from my systemd service.

Is it something serious to post it as an issue on Github?

jkandasa

Hi @j54n1n, yes, please report in GitHub. Thanks for your time on this!

@j54n1n Are you seeing this issue on startup of the MyController server?

j54n1n

@jkandasa yes it was at startup, but only once so far and after a restart of the service I did not see that again. Maybe some type of race condition? Could it be that it depends if either influxdb or mosquitto are ready or not at boot?

This is the service unit file that I am using:

[Unit]
Description=MyController.org v2 daemon
Requires=network.target
After=influxdb.service

[Service]
User=mycontroller
Group=mycontroller
WorkingDirectory=/opt/apps/mycontroller
ExecStart=/opt/apps/mycontroller/mycontroller-server -config /opt/apps/mycontroller/mycontroller.yaml

[Install]
WantedBy=multi-user.target

jkandasa

@j54n1n Yes, it should be race condition. I will look into the code carefully.

Hi, I'm interested. Can I contact you in PM?

I'm trying to install the docker image, but can't get it to start up... Dosn't seem to pick up the yaml file as using defaults... {"error": "Get \"https://ipinfo.io/json\": dial tcp 0.0.0.0:443: connect: connection refused"} ```

I've install everything on the quick install page... and use the following docker command

docker run --detach --name mycontroller2b   --publish 8081:8080   --publish 8443:8443   --publish 9443:9443   --volume /root/mycontroller/mc_home:/mc_home   --volume /root/mycontroller/mycontroller.yaml:/app/mycontroller.yaml   --env TZ="Europe/Prague"   --restart unless-stopped   docker.io/mycontroller/server:master

is the

:/app/mycontroller.yaml

correct ?
Thanks

@rmf69 said in MyController 2.0 is ready for testing:

{"error": "Get "https://ipinfo.io/json\": dial tcp 0.0.0.0:443: connect: connection refused"}

This error may be due to you do not have internet access of your firewall blocks https://ipinfo.io/json
To avoid this error disable auto location detection feature and enter your location details manually.

I do not see any error in the docker run. Can you please double check the availability of the mycontroller.yaml on your host machine?

enter into the docker container and verify the file

# docker exec -it mycontroller2b /bin/sh
/app # cat /app/mycontroller.yaml
