Each of our IDs consists of:

41 bits for time in milliseconds (gives us 41 years of IDs with a custom epoch) 13 bits that represent the logical shard ID 10 bits that represent an auto-incrementing sequence, modulus 1024. This means we can generate 1024 IDs, per shard, per millisecond Let’s walk through an example: let’s say it’s September 9th, 2011, at 5:00pm and our ‘epoch’ begins on January 1st, 2011. There have been 1387263000 milliseconds since the beginning of our epoch, so to start our ID, we fill the left-most 41 bits with this value with a left-shift:

id = 1387263000 << (64-41)

Next, we take the shard ID for this particular piece of data we’re trying to insert. Let’s say we’re sharding by user ID, and there are 2000 logical shards; if our user ID is 31341, then the shard ID is 31341 % 2000 -> 1341. We fill the next 13 bits with this value:

	先删除运行的image
	sudo docker ps -a \| grep Exit \| awk '{print $1}' \| sudo xargs docker rm
	然后删除docker images下不用的
