Subject: docker-ce: Expand nofile from 1024(soft) 4096(hard) as large as possible when using... 
X-Git-Url: http://git.99rst.org/?a=commitdiff_plain;h=72c8ba7ee56fd7818e480991e37db0ed8ac7e97a;p=openwrt-packages.git

docker-ce: Expand nofile from 1024(soft) 4096(hard) as large as possible when using procd.
When we run docker image and export too many ports, dockerd will output some errors like "too many open files", it is caused by max-file limitation.
Now, we start dockerd using procd, just add a statement to fix this problem.
