.NET Client for Docker Remote API
This library allows you to interact with Docker Remote API endpoints in your .NET applications.
It is fully asynchronous, designed to be non-blocking and object-oriented way to interact with your Docker daemon programmatically.
Versioning
Version of this package uses SemVer format: MAJOR.MINOR.PATCH
. MINOR
segment indicates
the Docker Remote API version support. For instance v2.124.0
of this library supports
Docker Remote API v1.24
. This does not guarantee backwards compatibility as Docker Remote API does not guarantee that either.
MAJOR
is reserved for major breaking changes we make to the library itself such as how
the calls are made or how authentication is made. PATCH
is just for incremental bug fixes
or non-breaking feature additions.
Installation
You can add this library to your project using NuGet.
Package Manager Console Run the following command in the “Package Manager Console”:
PM> Install-Package Docker.DotNet
Visual Studio Right click to your project in Visual Studio, choose “Manage NuGet Packages” and search for ‘Docker.DotNet’ and click ‘Install’. (see NuGet Gallery.)
.NET Core Command Line Interface Run the following command from your favorite shell or terminal:
dotnet add package Docker.DotNet
Development Builds
If you intend to use development builds of Docker.DotNet and don't want to compile the code yourself you can add the package source below to Visual Studio or your Nuget.Config.
Usage
You can initialize the client like the following:
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration(
new Uri("http://ubuntu-docker.cloudapp.net:4243"))
.CreateClient();
or to connect to your local Docker for Windows daemon using named pipes or your local Docker for Mac daemon using Unix sockets:
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration()
.CreateClient();
For a custom endpoint, you can also pass a named pipe or a Unix socket to the DockerClientConfiguration
constructor. For example:
// Default Docker Engine on Windows
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration(
new Uri("npipe://./pipe/docker_engine"))
.CreateClient();
// Default Docker Engine on Linux
using Docker.DotNet;
DockerClient client = new DockerClientConfiguration(
new Uri("unix:///var/run/docker.sock"))
.CreateClient();
Example: List containers
IList<ContainerListResponse> containers = await client.Containers.ListContainersAsync(
new ContainersListParameters(){
Limit = 10,
});
Example: Create an image by pulling from Docker Registry
The code below pulls fedora/memcached
image to your Docker instance using your Docker Hub account. You can
anonymously download the image as well by passing null
instead of AuthConfig object:
await client.Images.CreateImageAsync(
new ImagesCreateParameters
{
FromImage = "fedora/memcached",
Tag = "alpha",
},
new AuthConfig
{
Email = "test@example.com",
Username = "test",
Password = "pa$$w0rd"
},
new Progress<JSONMessage>());
Example: Create a container
The following code will create a new container of the previously fetched image.
await client.Containers.CreateContainerAsync(new CreateContainerParameters()
{
Image = "fedora/memcached",
HostConfig = new HostConfig()
{
DNS = new[] { "8.8.8.8", "8.8.4.4" }
}
});
Example: Start a container
The following code will start the created container.
await client.Containers.StartContainerAsync(
"39e3317fd258",
new ContainerStartParameters()
);
Example: Stop a container
The following code will stop a running container.
Note: WaitBeforeKillSeconds
field is of type uint?
which means optional. This code will wait 30 seconds before
killing it. If you like to cancel the waiting, you can use the CancellationToken parameter.
var stopped = await client.Containers.StopContainerAsync(
"39e3317fd258",
new ContainerStopParameters
{
WaitBeforeKillSeconds = 30
},
CancellationToken.None);
Example: Dealing with Stream responses
Some Docker API endpoints are designed to return stream responses. For example Monitoring Docker events continuously streams the status in a format like :
{"status":"create","id":"dfdf82bd3881","from":"base:latest","time":1374067924}
{"status":"start","id":"dfdf82bd3881","from":"base:latest","time":1374067924}
{"status":"stop","id":"dfdf82bd3881","from":"base:latest","time":1374067966}
{"status":"destroy","id":"dfdf82bd3881","from":"base:latest","time":1374067970}
...
To obtain this stream you can use:
CancellationTokenSource cancellation = new CancellationTokenSource();
Stream stream = await client.System.MonitorEventsAsync(new ContainerEventsParameters(), new Progress<JSONMessage>(), cancellation.Token);
// Initialize a StreamReader...
You can cancel streaming using the CancellationToken. On the other hand, if you wish to continuously stream, you can simply pass CancellationToken.None
.
Example: HTTPS Authentication to Docker
If you are running Docker with TLS (HTTPS), you can authenticate to the Docker instance using the Docker.DotNet.X509
package. You can get this package from NuGet or by running the following command in the “Package Manager Console”:
PM> Install-Package Docker.DotNet.X509
Once you add Docker.DotNet.X509
to your project, use CertificateCredentials
type:
var credentials = new CertificateCredentials (new X509Certificate2 ("CertFile", "Password"));
var config = new DockerClientConfiguration("http://ubuntu-docker.cloudapp.net:4243", credentials);
DockerClient client = config.CreateClient();
If you don't want to authenticate you can omit the credentials
parameter, which defaults to an AnonymousCredentials
instance.
The CertFile
in the example above should be a .pfx file (PKCS12 format), if you have .pem formatted certificates which Docker normally uses you can either convert it programmatically or use openssl
tool to generate a .pfx:
openssl pkcs12 -export -inkey key.pem -in cert.pem -out key.pfx
(Here, your private key is key.pem, public key is cert.pem and output file is named key.pfx.) This will prompt a password for PFX file and then you can use this PFX file on Windows. If the certificate is self-signed, your application may reject the server certificate, in this case you might want to disable server certificate validation:
//
// There are two options to do this.
//
// You can do this globally for all certificates:
// (Note: This is not available on netstandard1.6)
ServicePointManager.ServerCertificateValidationCallback += (o, c, ch, er) => true;
// Or you can do this on a credential by credential basis:
var creds = new CertificateCredentials(...);
creds.ServerCertificateValidationCallback += (o, c, ch, er) => true;
Example: Basic HTTP Authentication to Docker
If the Docker instance is secured with Basic HTTP Authentication, you can use the Docker.DotNet.BasicAuth
package. Get this package from NuGet or by running the following command in the “Package Manager Console”:
PM> Install-Package Docker.DotNet.BasicAuth
Once you added Docker.DotNet.BasicAuth
to your project, use BasicAuthCredentials
type:
var credentials = new BasicAuthCredentials ("YOUR_USERNAME", "YOUR_PASSWORD");
var config = new DockerClientConfiguration("tcp://ubuntu-docker.cloudapp.net:4243", credentials);
DockerClient client = config.CreateClient();
BasicAuthCredentials
also accepts SecureString
for username and password arguments.
Example: Specifying Remote API Version
By default this client does not specify version number to the API for the requests it makes. However, if you would like to make use of versioning feature of Docker Remote API You can initialize the client like the following.
var config = new DockerClientConfiguration(...);
DockerClient client = config.CreateClient(new Version(1, 16));
Error Handling
Here are typical exceptions thrown from the client library:
DockerApiException
is thrown when Docker API responds with a non-success result. Subclasses:DockerContainerNotFoundException
DockerImageNotFoundException
TaskCanceledException
is thrown fromSystem.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.
- Long-running methods (e.g.
ArgumentNullException
is thrown when one of the required parameters are missing/empty.- Consider reading the Docker Remote API reference 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.
