s6-overlay-suexec: fatal: can only run as pid 1

[TechnoDezi]

Summary

When attempting to run tiredofit/clamav:latest on Azure Container Instance I get the error "s6-overlay-suexec: fatal: can only run as pid 1" as the container is starting and then it never starts successfully.
The Version from 2021/04 seems to start fine, but clamAV is too out datated and can't download files.

Steps to reproduce

Add a container instance on Azure and set it up to use tiredofit/clamav:latest.

What is the expected correct behavior?

The container should start, load clam AV and update virus database.

I believe this is related to the upgrade of S6 Overlay from 2.x to 3.x in the base images.

Are you trying to launch this container as a scoped user?

Hi

Sorry for the delay. I think it must be yes. I'm not sure how Azure container instances start the container, but it's very likely scoped user.

Hi,
Any suggestion with this?
We are experiencing the same problem. Last version successfully run on Azure is 2.3.1.

Same problem here - pulling the 2.3.1 image from Docker into an Azure Container Instance works but any later image fails with the "s6-overlay-suexec: fatal: can only run as pid 1" error. Going back to the Alpine base, the 3.5-7.2.19 image works and 3.5-7.3.0 fails with the same error - the version where S6 was changed from 2 to 3.
