# `Hyper.Cfg.Jails`
[🔗](https://github.com/harmont-dev/hyper/blob/main/lib/hyper/cfg/jails.ex#L1)

VM confinement settings from the `[jails]` table — `config.toml`-only because
the setuid helper enforces the same `uid_gid_range` it reads from this file.

# `cgroup`

```elixir
@spec cgroup() :: String.t()
```

Parent cgroup for every VM cgroup. `[jails] cgroup`, default `"hyper"`.

# `uid_gid_range`

```elixir
@spec uid_gid_range() :: {integer(), integer()}
```

UID/GID allocation band each VM jail draws from (`[jails] uid_gid_range`, a
required `[min, max]` integer array). Raises `Hyper.Cfg.MissingError` when it
is unset, and `ArgumentError` when it is not a pair of integers — a bogus band
must never silently confine a VM.
