[![CI](https://github.com/testcontainers/Docker.DotNet/actions/workflows/ci.yml/badge.svg)](https://github.com/testcontainers/Docker.DotNet/actions/workflows/ci.yml)

## Usage

You can initialize the client like the following:
You can initialize the client as follows:

```csharp
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration(
new Uri("http://ubuntu-docker.cloudapp.net:4243"))
.CreateClient();
.CreateClient();
```

or to connect to your local [Docker Desktop on Windows](https://docs.docker.com/desktop/setup/install/windows-install/) daemon using named pipes or your local [Docker Desktop on Mac](https://docs.docker.com/desktop/setup/install/mac-install/) daemon using Unix sockets:
### Connection types and optional sub-packages

```csharp
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration()
.CreateClient();
Depending on the connection scheme and platform, additional sub-packages may be required:

- **Docker.DotNet.Enhanced.NPipe**: Support for named pipes on Windows (`npipe://`).
- **Docker.DotNet.Enhanced.Unix**: Support for Unix domain sockets on Linux/macOS (`unix://`).
- **Docker.DotNet.Enhanced.NativeHttp**: Native HTTP handler for specific platforms/scenarios.
- **Docker.DotNet.Enhanced.LegacyHttp**: Legacy HTTP handler for compatibility with older .NET versions.

These packages are optional and only needed if you want to use the respective protocol or handler. You can install them via NuGet, for example:

```console
PM> Install-Package Docker.DotNet.Enhanced.NPipe
PM> Install-Package Docker.DotNet.Enhanced.Unix
PM> Install-Package Docker.DotNet.Enhanced.NativeHttp
PM> Install-Package Docker.DotNet.Enhanced.LegacyHttp
```

For a custom endpoint, you can also pass a named pipe or a Unix socket to the `DockerClientConfiguration` constructor. For example:
**Examples:**

**Named Pipe (Windows):**

```csharp
// Default Docker Engine on Windows
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration(
new Uri("npipe://./pipe/docker_engine"))
.CreateClient();
.CreateClient();
```

**Unix Domain Socket (Linux/macOS):**

// Default Docker Engine on Linux
```csharp
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration(
new Uri("unix:///var/run/docker.sock"))
.CreateClient();
.CreateClient();
```

**Note:**
For HTTP(S) connections or special authentication types (e.g. X509, BasicAuth), see the corresponding sections below.

To connect to your local [Docker Desktop on Windows](https://docs.docker.com/desktop/setup/install/windows-install/) instance via named pipe or your local [Docker Desktop on Mac](https://docs.docker.com/desktop/setup/install/mac-install/) instance via Unix socket:

```csharp
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration()
.CreateClient();
```

For a custom endpoint, you can also explicitly pass a named pipe or Unix socket to the `DockerClientConfiguration` constructor (see examples above).

Here are typical exceptions thrown from the client library:

* **`DockerApiException`** is thrown when Docker Engine API responds with a non-success result. Subclasses:
* **``DockerContainerNotFoundException``**
* **``DockerImageNotFoundException``**
* **`TaskCanceledException`** is thrown from `System.Net.Http.HttpClient` library by design. It is not a friendly exception, but it indicates your request has timed out. (default request timeout is 100 seconds.)
* Long-running methods (e.g. `WaitContainerAsync`, `StopContainerAsync`) and methods that return Stream (e.g. `CreateImageAsync`, `GetContainerLogsAsync`) have timeout value overridden with infinite timespan by this library.
* **`ArgumentNullException`** is thrown when one of the required parameters are missing/empty.
* Consider reading the [Docker Remote API reference][docker-remote-api] and source code of the corresponding method you are going to use in from this library. This way you can easily find out which parameters are required and their format.
