• 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.

Suppose you want to inject a credential into a Pipeline script. The cloudbees note does not include Pipeline script examples. https://support.cloudbees.com/hc/en-us/articles/203802500-Injecting-Secrets-into-Jenkins-Build-Jobs

The Jenkins Pipeline Docs' description of the git pushmethod doesn't have an example using injected credentials. (https://jenkins.io/doc/pipeline/examples/#push-git-repo)

The Snippet generator is helpful, but not not if you try to follow the instructions at: https://wiki.jenkins-ci.org/display/JENKINS/Credentials+Binding+Plugin
