ACL v6RC1 default app profile

The purpose of this exercise is to define a "default" application ACL profile that can access the all the data without being able to cause too much harm.

Additive ("future-proof") profile

Required extra permissions:

  • All functional categories
  • CLIENT ID|GETNAME|REPLY|SETNAME|TRACKING|GETREDIR: must for modern clients
  • CLUSTER COUNTKEYSINSLOT|GETKEYSINSLOT|INFO|KEYSLOT|MYID|NODES|SLOTS: must for cluster-aware clients

Loading a binary value from a file with redis-cli

Create the file with the actual bytes, not the '\xnn\ representation. For example, in Python:

f = open('filename', 'w')
f.write('\x01\x02\x03')
f.close()

Load the file with redis-cli -x set keyname &lt; filename
