# slim

Turning containers into bootable VMs

## Example

```sh
# Build the container
podman build ./example/alpine -t slim-alpine

# Make the container bootable. slim injects /slim/init and /slim/exec,
# then packs the rootfs as a qcow2 disk.
slim build qcow2 slim-alpine

# Boot the image using QEMU. The container's CMD runs automatically.
slim run slim-alpine

# Override the command at runtime (base64-encoded on the kernel cmdline):
slim run slim-alpine --cmd '/bin/sh'

# Override the command at build time (baked into /slim/exec):
slim build qcow2 slim-alpine --cmd '/bin/sh'

# Cleanup
slim image rm slim-alpine
podman image rm slim-alpine
```

## Kernel

slim boots VMs using a shared kernel at `$XDG_DATA_HOME/slim-rs/vmlinuz`.
Place a suitable x86 bzImage there before running `slim run`.
