## Bollard: an asynchronous rust client library for the docker API

Bollard leverages the latest [Hyper](https://github.com/hyperium/hyper) and
[Tokio](https://github.com/tokio-rs/tokio) improvements for an asynchronous API containing
futures, streams and the async/await paradigm.

The library also features Windows support through Named Pipes and HTTPS support through
optional SSL bindings or a native TLS implementation.

## Install

Add the following to your `Cargo.toml` file

```nocompile
[dependencies]
bollard = "0.8"
```

## API
### Documentation

[API docs](https://docs.rs/bollard/).

As of version 0.6, this project now generates API stubs from the upstream Docker-maintained
[Swagger OpenAPI specification](https://docs.docker.com/engine/api/v1.40.yaml). The generated
models are committed to this repository, but packaged in a separate crate
[bollard-stubs](https://crates.io/crates/bollard-stubs).

### Version

The [Docker API](https://docs.docker.com/engine/api/v1.40/) is pegged at version `1.40`. The
library also supports [version
negotiation](https://docs.rs/bollard/latest/bollard/struct.Docker.html#method.negotiate_version),
to allow downgrading to an older API version.

## Usage

### Connecting with the docker daemon

Connect to the docker server according to your architecture and security remit.

#### Unix socket

The client will connect to the standard unix socket location `/var/run/docker.sock`. Use the
`Docker::connect_with_unix` method API to parameterise the interface.

```rust
use bollard::Docker;
#[cfg(unix)]
Docker::connect_with_unix_defaults();
```

#### Windows named pipe

The client will connect to the standard windows pipe location `\\.\pipe\docker_engine`. Use the
`Docker::connect_with_name_pipe` method API
to parameterise the interface.

```rust
use bollard::Docker;
#[cfg(windows)]
Docker::connect_with_named_pipe_defaults();
```

#### Local

The client will connect to the OS specific handler it is compiled for.
This is a convenience for localhost environment that should run on multiple
operating systems.
Use the `Docker::connect_with_local` method API to parameterise the interface.
```rust
use bollard::Docker;
Docker::connect_with_local_defaults();
```

#### HTTP

The client will connect to the location pointed to by `DOCKER_HOST` environment variable, or
`localhost:2375` if missing. Use the
`Docker::connect_with_http` method API to
parameterise the interface.

```rust
use bollard::Docker;
Docker::connect_with_http_defaults();
```

#### SSL via Rustls

The client will connect to the location pointed to by `DOCKER_HOST` environment variable, or
`localhost:2375` if missing.

The location pointed to by the `DOCKER_CERT_PATH` environment variable is searched for
certificates - `key.pem` for the private key, `cert.pem` for the server certificate and
`ca.pem` for the certificate authority chain.

Use the `Docker::connect_with_ssl` method API
to parameterise the interface.

```rust
use bollard::Docker;
#[cfg(feature = "ssl")]
Docker::connect_with_ssl_defaults();
```

### Examples

Note: all these examples need a [Tokio
Runtime](https://tokio.rs/).

#### Version

First, check that the API is working with your server:

```rust
use bollard::Docker;

use futures_util::future::FutureExt;

// Use a connection function described above
// let docker = Docker::connect_...;

async move {
    let version = docker.version().await.unwrap();
    println!("{:?}", version);
};
```

#### Listing images

To list docker images available on the Docker server:

```rust
use bollard::Docker;
use bollard::image::ListImagesOptions;

use futures_util::future::FutureExt;

use std::default::Default;

// Use a connection function described above
// let docker = Docker::connect_...;

async move {
    let images = &docker.list_images(Some(ListImagesOptions::<String> {
        all: true,
        ..Default::default()
    })).await.unwrap();

    for image in images {
        println!("-> {:?}", image);
    }
};
```

### Streaming Stats

To receive a stream of stats for a running container.

```rust
use bollard::Docker;
use bollard::container::StatsOptions;

use futures_util::stream::TryStreamExt;

use std::default::Default;

// Use a connection function described above
// let docker = Docker::connect_...;

async move {
    let stats = &docker.stats("postgres", Some(StatsOptions {
       stream: true,
       ..Default::default()
    })).try_collect::<Vec<_>>().await.unwrap();

    for stat in stats {
        println!("{} - mem total: {:?} | mem usage: {:?}",
            stat.name,
            stat.memory_stats.max_usage,
            stat.memory_stats.usage);
    }
};
```

## Examples

Further examples are available in the [examples
folder](https://github.com/fussybeaver/bollard/tree/master/examples), or the [integration/unit
tests](https://github.com/fussybeaver/bollard/tree/master/tests).

## Development

Contributions are welcome, please observe the following advice.

## Building the stubs

Serialization stubs are generated through the [Swagger
library](https://github.com/swagger-api/swagger-codegen/). To generate these files, use the
following in the `codegen` folder:

```bash
mvn -D org.slf4j.simpleLogger.defaultLogLevel=debug clean compiler:compile generate-resources
```

## History

This library was originally forked from the [boondock rust
library](https://github.com/faradayio/boondock).  Many thanks to the original authors for the
initial code and inspiration.

## Integration tests

Running the integration tests by default requires a running docker registry, with images tagged
and pushed there. To disable this behaviour, set the `DISABLE_REGISTRY` environment variable.

```bash
docker run -d --restart always --name registry -p 5000:5000 registry:2
docker pull hello-world:linux
docker pull fussybeaver/uhttpd
docker pull alpine
docker tag hello-world:linux localhost:5000/hello-world:linux
docker tag fussybeaver/uhttpd localhost:5000/fussybeaver/uhttpd
docker tag alpine localhost:5000/alpine
docker push localhost:5000/hello-world:linux
docker push localhost:5000/fussybeaver/uhttpd
docker push localhost:5000/alpine
docker swarm init
REGISTRY_HTTP_ADDR=localhost:5000 cargo test -- --test-threads 1
```
