# Bascule Shell Images

Curated container images for right-sized operator environments.

| Image | Contents | Approx. Size |
|-------|----------|-------------|
| `bascule-shell:minimal` | bash, coreutils, curl, jq, ssh | ~50MB |
| `bascule-shell:k8s-ops` | + kubectl, helm | ~120MB |
| `bascule-shell:net-ops` | + nmap, dig, traceroute, tcpdump, nft | ~90MB |
| `bascule-shell:dev` | + git, make, gcc, python3, vim | ~250MB |

## Building

```bash
docker build -t bascule-shell:minimal images/minimal/
docker build -t bascule-shell:k8s-ops images/k8s-ops/
docker build -t bascule-shell:net-ops images/net-ops/
docker build -t bascule-shell:dev images/dev/
```

## Right-Sizing

Choose the smallest image that contains the tools your operators need. If it's not in the image, the operator can't use it — the container IS the access boundary.

## Custom Images

Build your own image from any base:

```dockerfile
FROM bascule-shell:k8s-ops
USER root
RUN microdnf install -y your-custom-tool
USER operator
```
