etcd: Start a single-node etcd cluster with a custom name.

etcd

$ etcd --name ${my_etcd_cluster}

try on your machine

The command "etcd --name ${my_etcd_cluster}" is invoking the "etcd" binary with the "--name" flag followed by the value of the "my_etcd_cluster" environment variable.

Here is a breakdown of the command:

"etcd": It is the name of the binary/executable being executed. "etcd" is a distributed key-value store that provides a reliable way to store data across a cluster of machines.
"--name": It is a flag/option for specifying the name of the etcd member/node in the cluster. The value immediately following this flag is the name of the etcd cluster member/node.
"${my_etcd_cluster}": It is a variable reference that retrieves the value stored in the "my_etcd_cluster" environment variable. The actual value will be substituted at runtime before execution.

In summary, this command starts the etcd member/node and sets its name to the value stored in the "my_etcd_cluster" environment variable. The name is important for identifying the member within the etcd cluster.
