Config error on boot

General questions

Hello, after upgrade to vyos 1.4.0 RC1 → RC3, I get this error. I’m not sure how to get rid of it. Have rebooted the router, but nothing seems to help?

$ configure
WARNING: There was a config error on boot: saving the configuration now could overwrite data. 
You may want to check and reload the boot config

/var/log/messages
vyos-router[964]: Starting VyOS router: migrate configure failed!

best way to figure this out is to get a copy of the current config and save it, then reboot to the previous version and compare

I’ve been seeing you can see what failed with compare 0 after a reboot
Example:

vyos@vyos# compare commands 0
delete protocols mpls interface 'eth10'
delete protocols pim interface eth10
delete protocols pim rp address 10.0.0.1 group '224.0.0.0/4'

Those appear to have been deleted during the failed migration.

Hello,

# compare commands 0
delete container ....

All set of “container *” is removed after reboot. I think it’s a bug?

Tested on 1.4.0-epa2

Execute those commands
conf
load
commit

And check the output

Hi, here is the output. Ty!

$ conf
WARNING: There was a config error on boot: saving the configuration now could overwrite data.

t# load
Loading configuration from 'config.boot'
Load complete. Use 'commit' to make changes effective.

It looks to me that this config (container) breaks firewall and also does not start correctly vyos.

set container name node-exporter allow-host-networks
set container name node-exporter description 'Prometheus Node Exporter'
set container name node-exporter image 'quay.io/prometheus/node-exporter:latest'
set container name node-exporter port node-exporter destination '9100'
set container name node-exporter port node-exporter protocol 'tcp'
set container name node-exporter port node-exporter source '9100'
set container name node-exporter volume hostroot destination '/host'
set container name node-exporter volume hostroot source '/'
set container registry quay.io

Thanks for help.
