OpenSearch Playground
OpenSearch is an open-source, enterprise-grade search and observability suite that brings order to unstructured data at scale.
🔧 System Components
opensearch: The core search and analytics engine.opensearch-dashboards: Web-based visualization and exploration interface (similar to Kibana).
🛠️ Tools
curl: Primary tool for interacting with OpenSearch REST API.jq: JSON processor for formatting and filtering API responses.
🎯 Getting Started
Authentication
OpenSearch requires authentication for all operations.
The administrator credentials are:
- 👤 Username:
admin - 🔒 Password:
Iximiuz123!
You can authenticate using:
# Using credentials directly
curl -u admin:Iximiuz123! -k "https://localhost:9200/_cluster/health" | jq
# Using .netrc file (recommended)
curl -n -k "https://localhost:9200/_cluster/health" | jq
OpenSearch uses a self-signed TLS certificate. Use the -k flag with curl to skip certificate verification.
Check Cluster Health
# Check cluster status
curl -nk "https://localhost:9200/_cluster/health" | jq
# Get basic cluster info
curl -nk "https://localhost:9200/" | jq
# List all nodes
curl -nk "https://localhost:9200/_cat/nodes?v"
Working with Indices
# List all indices
curl -nk "https://localhost:9200/_cat/indices?v"
# Get index details
curl -nk "https://localhost:9200/.opendistro_security" | jq

A real VM, not a container
Get root on a VM with its own kernel, so Docker, Kubernetes, and systemd just work.

Drive it with AI
Let Claude, Codex, or any MCP client start this playground and run commands in it.
Read the docs →
Expose HTTP(S) ports
Give any web app running inside the VM a public URL - for yourself or to share with others.

Share terminals
Invite others into your terminal session, or open it yourself from another device.

Customize with init scripts
Add shell scripts that run at boot to install packages, clone repos, or seed test data.

Private networking
VMs reach the internet via NAT with no public IP; several VMs share bridge networks.

Ephemeral or persistent
By default, VMs are destroyed when the session ends; enable persistence to keep the disks for next time.

Built-in container registry
A private registry.iximiuz.com for every playground to share images across services and VMs.
