| + | Problem is located in RO /sys filesystem, not in values itself. Host already has huge values set, enough to run Gitlab: | ||
| + | <code bah> | ||
| + | # sysctl kernel.shmmax | ||
| + | kernel.shmmax = 18446744073692774399 | ||
| + | </code> | ||
| + | |||
| + | Solution is to configure gitlab again and again, to skip installator part. Gitlab reconfigure will detect that LXC host has correct variable: | ||
| + | <code bash> | ||
| + | dpkg --configure -a | ||
| + | gitlab-ctl reconfigure | ||
| + | </code> | ||
| + | |||
| + | Some LXC configuration trick (can work with privileged containers) | ||
| + | |||
| + | <file /etc/pve/nodes/pve3/lxc/201.conf> | ||
| + | lxc.apparmor.profile: unconfined | ||
| + | lxc.mount.auto: sys:rw | ||
| + | </file> | ||
