Increase ulimit -l

[jakajancar]

Moby's /etc/init.d/docker currently sets

    # set ulimits as high as possible
    ulimit -n 1048576
    ulimit -p unlimited

Can you also please set ulimit -l higher? We need it for Varnish.

What sort of value do you need?

[justincormack]

Ok, 82000 seems to be recommended. https://www.varnish-cache.org/lists/pipermail/varnish-misc/2011-August/020949.html

@jakajancar you can increase the limits to the recommended value with docker run --ulimit memlock=85983232:85983232 varnish but I will increase the default as it is pretty low.

[justincormack]

The default will be increased in the next beta.

[jakajancar]

@justincormack Can you explain how you got to 85983232?

[justincormack]

82 Megabytes. The ulimit specification in the docker run command is in bytes, while for the shell it is in k it seems.

(82000k may in fact be sufficient)

[jakajancar]

Ah, ok.

Although if varnish there has 82000 KB (not 82 MB), then that's 83968000 B, no? Not that it matters, probably.

[justincormack]

No, it doesnt make much difference, as it is a maximum
