Volcano Engine ESCloud (Elasticsearch + OpenSearch)

Manage ESCloud instances on Volcano Engine — cluster lifecycle (control plane) and index/doc operations (data plane).

Choose the right plane

• Provision / scale / delete instances? → use scripts/control.py and read CONTROL_PLANE.md
• Create indices / write docs / search / bulk ingest? → use scripts/data.py and read DATA_PLANE.md

Setup (once per environment)

Create a Python venv on first use (not bundled in the repo):

cd {baseDir}
python3 -m venv {baseDir}/venv
{baseDir}/venv/bin/pip install -r {baseDir}/requirements.txt

Then run scripts with the venv Python:

cd {baseDir}
{baseDir}/venv/bin/python {baseDir}/scripts/control.py <command>
{baseDir}/venv/bin/python {baseDir}/scripts/data.py <command>

If you see a "Missing Dependency" error at runtime, (re)install dependencies:

cd {baseDir}
{baseDir}/venv/bin/python -m pip install -r {baseDir}/requirements.txt

Quick start (common tasks)

# List instances
{baseDir}/venv/bin/python {baseDir}/scripts/control.py list

# Inspect an instance
{baseDir}/venv/bin/python {baseDir}/scripts/control.py detail --id <instance-id>

# Show supported versions (best-effort)
{baseDir}/venv/bin/python {baseDir}/scripts/control.py versions

# Check connectivity (data plane)
{baseDir}/venv/bin/python {baseDir}/scripts/data.py --endpoint <https://domain:9200> info

Available operations

Control Plane (instance management): Create, list, inspect, scale, and delete ESCloud instances. Query VPCs, subnets, zones, and node specs. Manage IP allowlist and reset admin password. → See CONTROL_PLANE.md for commands and workflows.

Data Plane (index & documents): Create/delete/list indices, write/read/delete documents, search, and bulk ingest via opensearch-py. Works with OpenSearch and (limited) Elasticsearch. → See DATA_PLANE.md for commands and workflows.

Out of scope

• Running or managing ES/OpenSearch outside Volcano Engine.
• Embedding generation (you must provide vectors if you want vector search).
• Advanced admin features (ILM/snapshots/security) unless added explicitly later.

Rules

• Execution environment: Always use {baseDir}/venv/bin/python to run scripts.
• Authentication: VOLCENGINE_AK and VOLCENGINE_SK are required for all control-plane operations. VOLCENGINE_REGION is optional (default: cn-beijing).
• Destructive actions: Always require explicit user confirmation before running delete operations (instance delete, index delete, delete-by-query, etc.). The CLIs also require --confirm for delete commands.
• Missing parameters: Never fail silently. If IDs/specs are missing, fetch available options (VPCs, subnets, node specs) and present them to the user.
• Connectivity: Before data-plane operations, validate the endpoint is reachable (run data.py info). If unreachable, fail fast and advise checking IP allowlist / public endpoint / credentials.
• Language: Reply in the user's preferred language.
