The Etcd plugin provides access to an etcd key-value data store.
API
Implements API described in the skeleton: The plugin is documented in more detail in the doc.go file.
Configuration
- Location of the Etcd configuration file can be defined either by the
command line flag
etcdv3-configor set via theETCDV3_CONFIGenvironment variable.
Status Check
- If injected, Etcd plugin will use StatusCheck plugin to periodically issue a minimalistic GET request to check for the status of the connection. The etcd connection state affects the global status of the agent. If agent cannot establish connection with etcd, both the readiness and the liveness probe from the probe plugin will return a negative result (accessible only via REST API in such case).
