Docker issue while connecting with containerD on live server

Hello docker team,

Specs:
Server - Ubuntu 24.04.1 LTS
Docker installed using official documentation
Docker version - Docker version 27.4.1
containerd version - 1.7.24

Server - This is my company’s server (bare-metal) which we purchased (a long time ago). On top of which we run multiple production applications, gitlab, and other self hosted tools using docker.

Issue Explanation:
On April 10, around 3:30 AM we noticed that all sites running on that server were down. When I inspected the server I noticed that there were no running containers “docker ps” but also there were no stopped containers as well which was weird (docker ps -a). Before this I had more than 20 containers running.

The logs said this → “Failed to retrieve containerd version”

  • When I tried to start my containers using “docker compose up -d” I got this error
    “failed to create network gitlab-docker_default: Error response from daemon: Failed to program FILTER chain: iptables failed: iptables --wait -I FORWARD -o br-bf92dde6e60e -j DOCKER: iptables v1.8.10 (nf_tables): Chain ‘DOCKER’ does not exist
    Try iptables -h’ or ‘iptables --help’ for more information.
    (exit status 2)”

Logs also showed some issues related to DNS like this
“No non-localhost DNS nameservers are left in resolv.conf. Using default external servers”

“failed to query external DNS server” client-addr=“udp:127.0.0.1:55812” dns-server=“udp:127.0.0.53:53” error=“read udp 127.0.0.1:55812->127.0.0.53:53: i/o timeout” question=“;example.domain.com.\tIN\t AAAA”"

To resolve the DNS issue I added the DNS entry in my /etc/docker/daemon.json file

{
  "data-root": "/docker_drive/docker",
  "default-address-pools": [
    {
      "base": "172.17.0.0/16",
      "size": 24
    },
    {
      "base": "192.168.0.0/20",
      "size": 24
    }
  ],
  "dns": ["8.8.8.8", "8.8.4.4"]
}

I only added the dns option - the rest of the options were added from before.

After adding this, I restarted docker and it fixed the DNS issue as well as container not getting started issue.

But I want to know the root cause of this issue and how can I prevent this from happening again as I cant afford for this issue to happen again on my live server.

I checked the logs deeply and I believe the main cause of issue is this → “Failed to retrieve containerd version”

But I want to know why it happened.

Also, when I first checked my server after the sites went down - the RAM and storage of the servers were enough - so doesn’t look like it is caused because of resources.

I am not sharing the complete log file of docker but bits of it serial wise.

Log of docker April 10
1- Issue first started with this
"Apr 10 03:06:15 is-88336 dockerd[3019417]: time=“2025-04-10T03:06:15.321188323Z” level=warning msg=“Failed to retrieve containerd version” error=“Canceled: context canceled” "

2- Then I think docker was stopped automatically
“Apr 10 03:39:35 is-88336 systemd[1]: Stopping docker.service - Docker Application Container Engine…”

3- After the docker service started automatically after being stopped we got these logs

Also, when I do this
sudo containerd

WARN[0000] containerd config version `1` has been deprecated and will be converted on each startup in containerd v2.0, use `containerd config migrate` after upgrading to containerd 2.0 to avoid conversion on startup

What does this mean?

Please respond soon and thanks in advance.

Warm regards,

I wrote about that prt here:

It could indicate something similar to this:

Make sure there is nothing else managing iptables rules

I don’t have a link for that, but the following is just a warning

You can probably ignore that. I wrote about that here:

If the containerd version could not be retrieved, I guess containerd is failing so you could not even run

containerd --version

Or did you do that before you shared the version at the beginning of your message?
I’m not sure it is related, but your quoted error messge looks like single line. Was it reall a single line?
