Infra Clickhouse

clickhouse/infra-clickhouse

Sets up and manages ClickHouse using the clickhousectl CLI — installs and runs a local ClickHouse server for development, and creates managed ClickHouse Cloud services for production (authentication, service creation, schema migration, application connection). Use when the user wants to build an application with ClickHouse, set up a local ClickHouse dev environment, create tables and start querying, deploy ClickHouse to production or ClickHouse Cloud, or migrate from a local setup to the cloud.

ClickHouse with clickhousectl

clickhousectl manages ClickHouse in two environments:

Local — ClickHouse installed and running on the user's machine, for development.
Cloud — managed ClickHouse Cloud services, for production: fully managed, automatic scaling, backups, and upgrades.

This file routes to the right reference. The step-by-step workflows live in ref/local.md and ref/cloud.md — read the one that matches the user's situation before running commands.

Which reference to use

| The user wants to... | Read |

|----------------------|------|

| Build an app with ClickHouse, develop or prototype locally, no cloud account needed | ref/local.md |

| Go to production, host a managed ClickHouse, or use ClickHouse Cloud explicitly | ref/cloud.md |

| Operate an existing cloud service (schemas, users, queries against it) | ref/cloud.md |

| Develop locally now, ship to production later | Start with ref/local.md; it points to ref/cloud.md when it's time to go to prod |

If it's genuinely ambiguous (e.g. "set up ClickHouse for my app"), default to local for development tasks and ask before creating anything in the cloud — cloud services cost money.

Prerequisites (both workflows)

Check that clickhousectl is installed:

which clickhousectl

If not found, install it:

curl -fsSL https://clickhouse.com/cli | sh

This installs to ~/.local/bin/clickhousectl (with a chctl alias). If the command is still not found, suggest export PATH="$HOME/.local/bin:$PATH" or a new terminal.

All commands accept --json for machine-readable output. Exit codes follow gh conventions: 0 success, 1 error, 2 cancelled, 4 auth required.

When designing schemas, consult the clickhouse-best-practices skill for ORDER BY selection, data types, and partitioning.
For Postgres (local development or managed ClickHouse Cloud Postgres), use the infra-postgres skill.

How to use it

Copy the folder

Take clickhouse/infra-clickhouse from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
