etcd 3.7

Reading from etcd

Official etcd 3.7 guides for developers, operators, upgrades, APIs, and internals.

Prerequisites

Install etcdctl

Procedure

Use the get subcommand to read from etcd:

$ etcdctl --endpoints=$ENDPOINTS get foo
foo
Hello World!
$

where:

foo is the requested key
Hello World! is the retrieved value

Or, for formatted output:

$ etcdctl --endpoints=$ENDPOINTS --write-out="json" get foo
{"header":{"cluster_id":289318470931837780,"member_id":14947050114012957595,"revision":3,"raft_term":4,
"kvs":[{"key":"Zm9v","create_revision":2,"mod_revision":3,"version":2,"value":"SGVsbG8gV29ybGQh"}]}}
$

where write-out="json" causes the value to be output in JSON format (note that the key is not returned).
