systemd's service unit should set LimitNOFILE to 1048576 like docker does #3201
Description
Description
I've just checked the limit on the max number of opened files for the containerd process on recent version of Container Optimized OS and saw that the process has the limit set to 65536.
I believe it should be set to 1048576 like docker does right now: moby/moby@428d733
Steps to reproduce the issue:
$ cat /usr/lib/systemd/system/containerd.service | grep LimitNOFILE
LimitNOFILE=infinity
$ systemctl show containerd | grep LimitNOFILE
LimitNOFILE=18446744073709551615
$ cat /proc/$(pgrep containerd | head -1)/limits | grep files
Max open files 65536 65536 filesDescribe the results you expected:
$ cat /proc/$(pgrep containerd | head -1)/limits | grep files
Max open files 1048576 1048576 filesOutput of containerd --version:
