podman

podman is a skill for Claude Code, Codex from BagelHole/DevOps-Security-Agent-Skills. It costs 45 tokens per session (2,006 once invoked), scanned B, original, MIT.

A tool for running and managing containers without requiring a background daemon. Podman offers Docker-compatible commands, rootless operation, container groups called pods, and systemd integration.

In plain words
What is it for?
Use it to run, stop, inspect, and log containers; manage images; create pods; and manage container services with systemd.
Why use it?
It allows containers to run without root privileges or a Docker daemon, which can suit systems with stricter security requirements.

SkillSpector: 12 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.

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

podman 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.

Podman

Run and manage containers without a daemon using Podman's rootless container engine.

When to Use This Skill

Use this skill when:

  • Running containers without root privileges
  • Managing containers on systems without Docker
  • Creating pod-based container groups
  • Using systemd for container management
  • Working in security-conscious environments

Prerequisites

  • Podman installed (4.x+)
  • For rootless: user namespaces enabled
  • Basic container concepts understanding

Key Differences from Docker

Feature Docker Podman
Architecture Client-daemon Daemonless
Root required Default Optional (rootless)
Pod support No Yes (Kubernetes-style)
Systemd integration Limited Native
Socket docker.sock podman.sock (optional)

Basic Commands

Container Operations

# Run container (identical to Docker)
podman run -d --name webserver -p 8080:80 nginx

# List containers
podman ps -a

# Stop and remove
podman stop webserver
podman rm webserver

# Execute command
podman exec -it webserver /bin/sh

# View logs
podman logs -f webserver

Image Management

# Pull image
podman pull docker.io/library/nginx:latest

# List images
podman images

# Build image
podman build -t myapp:latest .

# Push to registry
podman push myapp:latest registry.example.com/myapp:latest

# Remove image
podman rmi nginx:latest

Rootless Containers

Setup

# Check user namespace support
cat /proc/sys/user/max_user_namespaces

# Enable if needed (as root)
echo "user.max_user_namespaces=28633" | sudo tee /etc/sysctl.d/userns.conf
sudo sysctl -p /etc/sysctl.d/userns.conf

# Configure subuid/subgid for user
sudo usermod --add-subuids 100000-165535 --add-subgids 100000-165535 $USER

# Verify
podman unshare cat /proc/self/uid_map

Running Rootless

# Run as regular user (no sudo)
podman run -d --name myapp -p 8080:80 nginx

# Check user namespace mapping
podman unshare id

# Verify non-root
podman top myapp user

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.

podman is a skill published in the GitHub repository BagelHole/DevOps-Security-Agent-Skills (1,058 stars, last pushed 3mo ago), licensed MIT. It adds 45 tokens to every session and 2,006 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
