zookeepercli: lightweight, powerful, controlled command line client for ZooKeeper

I’m happy to announce the availability of zookeepercli: a lightweight, simple, fast and controlled command line client for ZooKeeper.

zookeepercli allows for:

• Basic CRUD-like operations: create,  set,  delete,  exists,  get,  ls (aka children).
• Extended operations: lsr (ls recursive),  creater (create recursively)
• Well formatted and controlled output: supporting either txt or json format
• Single, no-dependencies binary file, based on a native Go ZooKeeper library by github.com/samuel/go-zookeeper (LICENSE)

I was dissatisfied with existing command line access to ZooKeeper. Uncontrolled and noisy output as well as large footprint were among the reasons. zookeepercli overcomes the above and provides with often required powers.

Usage samples:

$ zookeepercli --servers srv-1,srv-2,srv-3 -c create /demo_only "path placeholder"
$ zookeepercli --servers srv-1,srv-2,srv-3 -c create /demo_only/key1 "value1"
$ zookeepercli --servers srv-1,srv-2,srv-3 -c create /demo_only/key2 "value2"
$ zookeepercli --servers srv-1,srv-2,srv-3 -c create /demo_only/key3 "value3"

$ zookeepercli --servers srv-1,srv-2,srv-3 -c ls /demo_only
key3
key2
key1

# Same as above, JSON format output:
$ zookeepercli --servers srv-1,srv-2,srv-3 --format=json -c ls /demo_only
["key3","key2","key1"]

$ zookeepercli --servers srv-1,srv-2,srv-3 -c delete /demo_only/key1
$ zookeepercli --servers srv-1,srv-2,srv-3 -c delete /demo_only/key2
$ zookeepercli --servers srv-1,srv-2,srv-3 -c delete /demo_only/key3
$ zookeepercli --servers srv-1,srv-2,srv-3 -c delete /demo_only

# Create a path recursively (auto-generate parent directories if not exist):
$ zookeepercli --servers=srv-1,srv-2,srv-3 -c creater "/demo_only/child/key1" "val1"
$ zookeepercli --servers=srv-1,srv-2,srv-3 -c creater "/demo_only/child/key2" "val2"

$ zookeepercli --servers=srv-1,srv-2,srv-3 -c get "/demo_only/child/key1"
val1

# This path was auto generated due to recursive create:
$ zookeepercli --servers=srv-1,srv-2,srv-3 -c get "/demo_only" 
zookeepercli auto-generated

# ls recursively a path and all sub children:
$ zookeepercli --servers=srv-1,srv-2,srv-3 -c lsr "/demo_only" 
child
child/key1
child/key2
