Build HO Image

Build HO Image is a skill for Claude Code, Codex from openshift/hypershift. It costs 29 tokens per session (829 once invoked), scanned A, original, Apache-2.0.

A procedure for building and uploading a custom HyperShift Operator container image. A container image packages an application and its runtime so it can be deployed to a cluster.

In plain words
What is it for?
Use it after changing the HyperShift Operator, especially when running end-to-end tests against a live cluster.
Why use it?
It lets developers test operator code changes in a live HyperShift environment before broader deployment.

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 A, and why

Build HO Image scanned grade A with 0 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 5d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Build HyperShift-Operator Image

This skill enables building and pushing custom hypershift-operator (HO) images for testing changes in a live HyperShift environment.

When to Use This Skill

This skill automatically applies when:

  • You've made changes to code in hypershift-operator/
  • You need to test HO changes against a live cluster
  • The user asks to build/push a HO image
  • You need to iterate on HO fixes with e2e tests

Prerequisites

Source the environment file before using this skill:

source dev/claude-env.sh

Image Registry Configuration

Environment variables from dev/claude-env.sh:

Variable Description
HO_IMAGE_REPO Container registry for HO images
RUNTIME Container runtime (podman/docker)

Building the HO Image

Step 1: Generate a Unique Tag

Use a tag that identifies the change (branch name, feature, or timestamp):

# Option 1: Use branch name
TAG=$(git rev-parse --abbrev-ref HEAD | tr '/' '-')

# Option 2: Use short commit hash
TAG=$(git rev-parse --short HEAD)

# Option 3: Use descriptive name + number for iterations
TAG="feature-name-1"

Step 2: Build the Image

The HO image uses the main Dockerfile:

$RUNTIME build -f Dockerfile --platform linux/amd64 -t $HO_IMAGE_REPO:$TAG .

Note: The build runs make hypershift, make hypershift-operator, make karpenter-operator, and make product-cli inside the container.

Step 3: Push the Image

$RUNTIME push $HO_IMAGE_REPO:$TAG

Quick One-Liner

Build and push in one command:

TAG="my-fix-1" && $RUNTIME build -f Dockerfile --platform linux/amd64 -t $HO_IMAGE_REPO:$TAG . && $RUNTIME push $HO_IMAGE_REPO:$TAG

Iteration Workflow

When iterating on HO fixes:

  1. Make code changes in hypershift-operator/
  2. Build and push image with incremented tag (e.g., fix-1, fix-2, fix-3)
  3. Reinstall HyperShift with new image
  4. Run e2e test or manual validation
  5. Analyze results
  6. Repeat until test passes

What this file has done since we first saw it

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.

Build HO Image is a skill published in the GitHub repository openshift/hypershift (540 stars, last pushed today), licensed Apache-2.0. It adds 29 tokens to every session and 829 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
