Redash installation problem in debian or ubuntu lxc proxmox container

Support Self Hosted Redash Support

hello

I try to install redash in a Debian or Ubuntu virtual machine (which is a lxc proxmox container)
and I always get these errors below when starting redis and postgres services

I guess it might come from the container ? Is there a workaround to make redash works in a lxc container?

thanks for help

This error isn’t specific to Redash. Have you tried Googling it? There appears to be a solution here that involves modifying the Dockerfile. It would be helpful to know what other debugging steps you’ve tried.

yes you’re right the problem is specific to docker when running in a lxc container
the first solution which works is to create a KVM virtual machine in proxmox… so the VM is better isolated from the host an docker runs successfully
but I will let you know if I find the good docker configuration with a LXC container
bye thanks
