Error on worker node

[JonathanMabiala]

I am running concurse in a ubuntu 24 lts ec2 instance (aws). My worker node can't seem to work i keep getting the following error:
run check: find or create container on worker ip-172-31-6-62: runc run: exit status 1: runc run failed: unable to start container process: error during container init: error mounting "cgroup" to rootfs at "/sys/fs/cgroup": mount /sys/fs/cgroup:/sys/fs/cgroup (via /proc/self/fd/10), flags: 0x100f: invalid argument

Please a little help will do.

Sounds similar to #9063, maybe switch to containerd or wait for a fix.

I did try using containerd like so:
CONCOURSE_WORKER_RUNTIME=containerd

it does not seem to work either.

i'm i doing it right?

Which version of Concourse are you using?
How are you running Concourse on the ec2? Systemd?

[JonathanMabiala]

It's the 7.12.1

[taylorsilva]

How are running Concourse? Systemd? A bash script you're running from your command line?

Either way, you should make sure the worker is running as root. Your error doesn't sound like a permissions issue, but maybe it is?
