  • [6.12.2] Can no longer set memory limits

    • Urgent


    It seems with the changes made when moving to cgroups-v2, docker is no longer able to set memory limits for containers, or control swap.


    Whenever I edit, update, or add a container with memory limits applied, the following warnings appear:


    WARNING: Your kernel does not support swap limit capabilities or the cgroup is not mounted. Memory limited without swap.
    WARNING: Your kernel does not support memory swappiness capabilities or the cgroup is not mounted. Memory swappiness discarded.


    I understand swap has never been 'officially' supported, but it appears that its now completely broken for docker in 6.12.x (working prior in 6.11.5) as well as the memory control.
