# Karapace Manifest v0.1 Specification
|
|
|
|
## Overview
|
|
|
|
The Karapace manifest is a TOML file (typically `karapace.toml`) that declaratively defines an environment. It is the single source of truth for environment identity.
|
|
|
|
## Schema
|
|
|
|
### Required Fields
|
|
|
|
| Field | Type | Description |
|
|
|---|---|---|
|
|
| `manifest_version` | `u32` | Must be `1`. |
|
|
| `base.image` | `string` | Base image identifier. Must not be empty. |
|
|
|
|
### Optional Sections
|
|
|
|
#### `[system]`
|
|
|
|
| Field | Type | Default | Description |
|
|
|---|---|---|---|
|
|
| `packages` | `string[]` | `[]` | System packages to install. Duplicates are deduplicated during normalization. |
|
|
|
|
#### `[gui]`
|
|
|
|
| Field | Type | Default | Description |
|
|
|---|---|---|---|
|
|
| `apps` | `string[]` | `[]` | GUI applications to install. |
|
|
|
|
#### `[hardware]`
|
|
|
|
| Field | Type | Default | Description |
|
|
|---|---|---|---|
|
|
| `gpu` | `bool` | `false` | Request GPU passthrough (`/dev/dri`). |
|
|
| `audio` | `bool` | `false` | Request audio device passthrough (`/dev/snd`). |
|
|
|
|
#### `[mounts]`
|
|
|
|
Flat key-value pairs. Each key is a label; each value is `<host_path>:<container_path>`.
|
|
|
|
- Labels must not be empty.
|
|
- The `:` separator is required.
|
|
- Absolute host paths are validated against the mount whitelist.
|
|
- Relative host paths (e.g. `./`) are always permitted.
|
|
|
|
#### `[runtime]`
|
|
|
|
| Field | Type | Default | Description |
|
|
|---|---|---|---|
|
|
| `backend` | `string` | `"namespace"` | Runtime backend: `namespace`, `oci`, or `mock`. |
|
|
| `network_isolation` | `bool` | `false` | Isolate network from host. |
|
|
|
|
#### `[runtime.resource_limits]`
|
|
|
|
| Field | Type | Default | Description |
|
|
|---|---|---|---|
|
|
| `cpu_shares` | `u64?` | `null` | CPU shares limit. |
|
|
| `memory_limit_mb` | `u64?` | `null` | Memory limit in MB. |
|
|
|
|
## Validation Rules
|
|
|
|
1. `manifest_version` must equal `1`.
|
|
2. Unknown fields at any level cause a parse error (`deny_unknown_fields`).
|
|
3. `base.image` must not be empty or whitespace-only.
|
|
4. Mount specs must contain exactly one `:` with non-empty sides.
|
|
|
|
## Normalization
|
|
|
|
During normalization:
|
|
|
|
- All string values are trimmed.
|
|
- `system.packages` and `gui.apps` are sorted, deduplicated.
|
|
- Mounts are sorted by label.
|
|
- `runtime.backend` is lowercased.
|
|
|
|
The normalized form is serialized to canonical JSON for hashing.
|
|
|
|
## Example
|
|
|
|
```toml
|
|
manifest_version = 1
|
|
|
|
[base]
|
|
image = "rolling"
|
|
|
|
[system]
|
|
packages = ["clang", "cmake", "git"]
|
|
|
|
[gui]
|
|
apps = ["ide", "debugger"]
|
|
|
|
[hardware]
|
|
gpu = true
|
|
audio = true
|
|
|
|
[mounts]
|
|
workspace = "./:/workspace"
|
|
|
|
[runtime]
|
|
backend = "namespace"
|
|
network_isolation = false
|
|
|
|
[runtime.resource_limits]
|
|
cpu_shares = 1024
|
|
memory_limit_mb = 4096
|
|
```
|
|
|
|
## Versioning
|
|
|
|
- The manifest format is versioned via `manifest_version`.
|
|
- Only version `1` is supported in Karapace 0.1.
|
|
- Future versions will increment this field.
|
|
- Backward-incompatible changes require a version bump.
