Error with containers switching between 1.4 and 1.3

mathias · February 15, 2023, 12:32pm

Hi,

I’ve started playing with the latest Sagitta image (1.4-rolling-202302110748) and deployed 2 containers successfully. Switching to a self-built 1.3 (build 20230214) image with container support I’m seeing the following error:

vyos@vyos:~$ show container
ERRO[0000] User-selected graph driver “overlay2” overwritten by graph driver “overlay” from database - delete libpod local files to resolve
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

23c79ffb3bb7 pihole 15 hours ago Up 15 hours ago pihole

This doesn’t seem to affect the containers themselves, all works fine.

However when creating a new container the commit fails:

Traceback (most recent call last):

Switching back to Sagitta resulted in 1 key error and multiple warnings:

time=“2023-02-15T12:24:11Z” level=warning msg=“Switching default driver from overlay2 to the equivalent overlay driver”

The error was a KeyError:

Traceback (most recent call last):
File “/usr/libexec/vyos/conf_mode/container.py”, line 401, in
generate(c)
File “/usr/libexec/vyos/conf_mode/container.py”, line 343, in generate

File “/usr/libexec/vyos/conf_mode/container.py”, line 233, in generate_run_arguments
memory = container_config[‘memory’]
KeyError: ‘memory’

After adding memory, similar error happened with shared_memory and restart. After adding all 3 keys the container was created successfully.
I’m 100% certain I didn’t have to add those keys when creating the 2 initial containers.

I’m not super-familiar with VyOS yet but I thought except /config everything else is in the image so those 2 images shouldn’t affect each other?
Is there a need to reset the container “cache” or something similar and if yes, how to do so without reinstalling the whole system?

At least with busybox don’t have such issues

set container name busybox allow-host-networks
set container name busybox image 'busybox'

show container:

vyos@r1# run show container

Did you downgrade 1.4 to 1.3 or 1.3 installs from scratch?
Could you share the container configuration?

mathias · February 15, 2023, 6:23pm

I added the 1.3 image and set default boot environment to it - I assume that’s what you mean with downgrade? If that’s not supported I apologize, I thought switching the image is basically replacing the whole system except /config.

Here is the container configuration:

set container name ntopng allow-host-networks
set container name ntopng cap-add ‘net-raw’
set container name ntopng cap-add ‘net-admin’
set container name ntopng image ‘ntop/ntopng:stable’
set container name pihole allow-host-networks
set container name pihole cap-add ‘net-admin’
set container name pihole cap-add ‘net-raw’
set container name pihole environment WEBPASSWORD value ‘vyos’
set container name pihole image ‘pihole’
set container name pihole memory ‘1024’
set container name pihole restart ‘always’
set container name pihole volume pihole_dnsmasq destination ‘/etc/dnsmasq.d/’
set container name pihole volume pihole_dnsmasq source ‘/config/docker/pihole/dnsmasq.d/’
set container name pihole volume pihole_etc destination ‘/etc/pihole/’
set container name pihole volume pihole_etc source ‘/config/docker/pihole/etc/’
set container name tailscale allow-host-networks
set container name tailscale cap-add ‘net-admin’
set container name tailscale cap-add ‘net-raw’
set container name tailscale image ‘tailscale/tailscale’
set container name tailscale memory ‘1024’
set container name tailscale restart ‘on-failure’
set container name tailscale shared-memory ‘128’
set container name tailscale volume devtun destination ‘/dev/net/tun’
set container name tailscale volume devtun source ‘/dev/net/tun’

I’ve had container issues with newer 1.4 rollings too. I ran containers fine for a long time with a 1.4 from late 2021 early 2022 without issue, but since trying more recent 1.4 rolling versions they would not start. I just upgraded one of my Vyos nodes to VyOS 1.4-rolling-202302120317, and I am trying to get my containers running again.

With this config:

set container name newrelic-vyos allow-host-networks
set container name newrelic-vyos environment NRIA_LICENSE_KEY value 'XXXXXXXXXXXXXXX'
set container name newrelic-vyos image 'newrelic/infrastructure:latest'
set container name newrelic-vyos volume logging.d destination '/etc/newrelic-infra/logging.d'
set container name newrelic-vyos volume logging.d source '/config/newrelic/logging.d'
set container name newrelic-vyos volume root destination '/host'
set container name newrelic-vyos volume root source '/'

The container repeatedly failed to start with errors like this:

I’ll try to spin up an older 1.4-rolling to see if I can reproduce a time when it did work

Does this help or is it different? I tried busybox as above and got more errors:

To answer my own question, I dug a bit.

Container storage is configured here:

/etc/containers/storage.conf

Which puts graphroot in

/usr/lib/live/mount/persistence/container/storage

That persists when switching images, so that’s possibly the explanation why I’m seeing issues. While overlay2 is the driver in both instances, 1.3 uses Podman 3.0.1 vs 4.3.1 in 1.4.

EDIT:
got it resolved by:

disabling all containers in 1.4
deleting the directoy content of /usr/lib/live/mount/persistence/container/storage
switching to 1.3
disabling all containers
adding the images of the containers with add container image
enabling all containers

No more error /warning in 1.3 after that. Doesn’t explain I suddenly got the KeyError messages and had to add keys that should have default values. Will report back if I can identify that one, too.

edan · February 15, 2023, 10:24pm

Thanks for replying! Maybe my problem has come from upgrading and then having a problem with the container storage.

I can report on a clean VyOS 1.4-rolling-202209300217 the same config as above started up the container without errors. I’ll try a clean install of the 1.4-rolling-202302120317 and see if that works too.

onedr0p · February 16, 2023, 4:03pm

The issue was reported here, with a workaround for now.
