use Math.sqrt(memory) to set container occupied memory according to system memory size, instead of setting fixed size, more reasonable.

• memory = `awk '($1 == "MemTotal:"){print $2/1048576}' /proc/meminfo`.to_i

if possible, avoid use linux/unix command. you can use File.readlines(file).find to get the line, and then handle the line

Thanks, Luan Shengde

• # set container available memory size, minimum size is 1g, maximum size is 30g, take the middle value according to the system memory size.
• [1, 30, Math.sqrt(memory)].sort[1].to_i
