upgrading-cluster-version

upgrading-cluster-version is a skill for Claude Code, Codex from cockroachlabs/cockroachdb-skills. It costs 79 tokens per session (2,733 once invoked), scanned B, original, Apache-2.0.

A guide to upgrading CockroachDB, a distributed SQL database, across different deployment types. It selects procedures for self-hosted clusters and CockroachDB Cloud tiers.

In plain words
What is it for?
Planning or performing a cluster version upgrade, configuring patch schedules or release channels, checking completion, and deciding whether to finalize or roll back a self-hosted upgrade.
Why use it?
Cluster upgrades differ depending on where CockroachDB runs and whether the change is major or a patch. This guide helps operators choose the relevant steps and check whether the upgrade finished safely.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

upgrading-cluster-version scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A mod that escalates privileges can change anything on the machine, not only the project.

Upgrading Cluster Version

Guides CockroachDB version upgrades end-to-end. Before providing procedures, this skill gathers deployment context to deliver only the steps relevant to the operator's tier.

When to Use This Skill

  • Planning or executing a version upgrade (Self-Hosted)
  • Initiating a major version upgrade via Cloud Console (Advanced, BYOC)
  • Configuring how patches are applied (Advanced, BYOC)
  • Verifying upgrade completion (all tiers)
  • Deciding whether to finalize or roll back (Self-Hosted)

For pre-upgrade health check: Use reviewing-cluster-health. For node drain during Self-Hosted upgrade: Use performing-cluster-maintenance. For maintenance window configuration: Use performing-cluster-maintenance.


Step 1: Gather Context

Required Context

Question Options Why It Matters
Deployment tier? Self-Hosted, Advanced, BYOC, Standard, Basic Completely different upgrade procedures per tier
Current version? e.g., v24.2.5 Validates upgrade path and compatibility

Additional Context (by tier)

If Self-Hosted:

Question Options Why It Matters
Upgrade type? Major (e.g., 24.2→24.3), Patch (e.g., 24.2.5→24.2.8) Major requires finalization; patches do not
Target version? e.g., v24.3.1 Confirms version is available and sequential
Deployment platform? Bare metal, VMs, Kubernetes (Operator/Helm/manual) Changes binary replacement and restart procedure
Process manager? systemd, manual, container orchestrator Changes stop/start commands
Node count? Number Affects upgrade sequencing

If Advanced or BYOC:

Question Options Why It Matters
Upgrade type? Major version, Patch Major requires Console initiation; patches use maintenance windows
Cloud provider? (BYOC only) AWS, GCP, Azure For infrastructure-level monitoring during upgrade
Release channel? Regular, Innovation Innovation gives latest features, shorter support window

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
