# `Docker.Config`
[🔗](https://github.com/joshrotenberg/docker_wrapper_ex/blob/v0.1.2/lib/docker/config.ex#L1)

Configuration for the Docker CLI wrapper.

Holds the path to the Docker binary, working directory, environment
variables, and timeout settings used when executing Docker commands.

# `t`

```elixir
@type t() :: %Docker.Config{
  binary: String.t(),
  env: [{String.t(), String.t()}],
  timeout: pos_integer(),
  working_dir: String.t() | nil
}
```

# `base_args`

```elixir
@spec base_args(t()) :: [String.t()]
```

Returns base arguments prepended to all Docker commands.

# `cmd_opts`

```elixir
@spec cmd_opts(t()) :: keyword()
```

Builds the options keyword list for `System.cmd/3`.

# `find_binary`

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

Finds the Docker-compatible binary on the system.

Checks the `DOCKER_PATH` environment variable first, then searches
for `docker`, `podman`, or `nerdctl` on the PATH.

Raises if no binary is found.

# `new`

```elixir
@spec new(keyword()) :: t()
```

Creates a new `Docker.Config` struct.

## Options

  * `:binary` - path to the Docker executable (default: auto-detected)
  * `:working_dir` - working directory for commands (default: `nil`, uses current directory)
  * `:env` - list of `{key, value}` tuples for environment variables (default: `[]`)
  * `:timeout` - command timeout in milliseconds (default: `30000`)

## Examples

    iex> config = Docker.Config.new()
    iex> config.binary != nil
    true

    iex> config = Docker.Config.new(timeout: 60_000)
    iex> config.timeout
    60_000
