etcdctl:tldr:e9100

This command etcdctl put ${my-key} ${my_value} is used to set a key-value pair in an etcd cluster.

Here's a breakdown of the command:

• etcdctl : This is the command-line tool used for interacting with etcd clusters.
• put : This is the command used to set a value for a specific key in the etcd cluster.
• ${my-key} : This is a placeholder for a variable that represents the key you want to set. You need to replace ${my-key} with the actual key you want to use.
• ${my_value} : This is a placeholder for a variable that represents the value you want to associate with the key. You need to replace ${my_value} with the actual value you want to use.

To use this command, you need to have etcdctl installed and configured to connect to your etcd cluster. The specific etcd cluster configuration should be set in the environment variables or provided as command-line flags.

Once you run this command with the appropriate key and value, it will set the key-value pair in the etcd cluster, which can be accessed later using the key.
