tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

What do Etcd, Consul, and Zookeeper do?

• Service Registration:
  • Host, port number, and sometimes authentication credentials, protocols, versions numbers, and/or environment details.
• Service Discovery:
  • Ability for client application to query the central registry to learn of service location.
• Consistent and durable general-purpose K/V store across distributed system.
  • Some solutions support this better than others.
  • Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
• Centralized locking can be based on this K/V store.
