I'm trying to remember if we had to bump any of the sysctls to actually reach 1024 containers, I don't think any of the usual suspects would be in play until you reach 2000+ Alpine containers though.

If you do run out of some kernel resources, you can try applying the following sysctls to get you past that:
net.ipv6.neigh.default.gc_thresh3 = 8192
net.ipv6.neigh.default.gc_thresh2 = 4096
net.ipv6.neigh.default.gc_thresh1 = 1024
net.ipv6.route.gc_thresh = 8192
kernel.pty.max = 65536
kernel.pid_max = 2097152
fs.inotify.max_queued_events = 1048576
fs.inotify.max_user_instances = 8192
fs.inotify.max_user_watches = 524288
