etcd Cluster Playground
A multi-node etcd cluster for exploring clustering and coordination features.
This environment is set up for learning how to work with etcd in a cluster configuration.
💡 This is a multi-node playground for etcd. For a simpler setup, try the single-node playground.
🔧 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(",")')
⚙️ Configuration
Check out the single-node playground to learn about configuring etcd.
