etcd Cluster Playground

This environment is set up for learning how to work with etcd in a cluster configuration.

🔧 System Components

• etcd: The distributed key-value store daemon running on multiple nodes.

🛠️ Tools

• etcdctl: The official command-line client for etcd.
• etcdutl: Utility for etcd database operations and maintenance.

🎯 Getting Started

Basic Cluster Operations

# Check etcd version and cluster health
etcdctl version
etcdctl endpoint health

# View cluster members
etcdctl member list

# Check cluster-wide health and status
etcdctl endpoint health --cluster
etcdctl endpoint status --cluster

Client Load Balancing

Set endpoints to all cluster nodes for client-side load balancing:

export ETCDCTL_ENDPOINTS=$(etcdctl member list -w json | jq -r '[.members[].clientURLs[]] | join(",")')
