Description

Hi,
I restored a Docker ioBroker container from backupfile of my RaspPi - works perfect.
After that I switched db to redis and created an additional ioBroker-slave-container.

After restart of the slave container the iob-docker-script tried to rename the ioBroker-slave and crashed.
If I set the env IOB_MULTIHOST=slave, the srcipt try to renew the db-connection and delete all my states.

How can I start the slave-container with my existing instance? ...without any changes from the script.

Image version

buanet/iobroker:latest-v8

Something went wrong. Looks like at least one parameter defining the custom db connection was not set properly or is missing.
Please check your configuration and try again.
For more information see ioBroker Docker Image Docs (https://docs.buanet.de/iobroker-docker-image/docs/).
 
This Script will exit now.

if I set IOB_OBJECTSDB_TYPE, ..._HOST, ..._PORT, ... the script overwrite my object db

How do you start your container?

I have stack with three container ...

  • host
  • slave
  • redis
    ...and start the stack with portainer.

redis and host works fine. slave restart again and again.

I've tested this and found an issue which may cause the described behaviour. So since v8 setting up a new slave (empty directory) causes an "iobroker setup first" call as the script is thinking it is a fresh iobroker instance.
I build a hotfix which makes sure this will not be called mehr IOB_MULTIHOST=slave.
I`ll test this and, if successful, release v8.0.1 Hotfix Release.

André
