Purview.Containers.Docker

The Docker backend for Purview.Containers.Core: throwaway containers for integration testing on any Docker daemon reachable from the test host — Docker Desktop, Docker Engine inside WSL2, a remote daemon, Docker-in-Docker, or the daemon a CI runner provides. It drives the daemon through Testcontainers for .NET.

dotnet add package Purview.Containers.Docker

await using var container = new ContainerBuilder()
    .WithImage("alpine:3.19")
    .WithCommand("/bin/sh", "-c", "echo ready && sleep 30")
    .WithWaitStrategy(Wait.ForLogMessage("ready"))
    .Build();

await container.StartAsync();
var result = await container.ExecAsync(["/bin/echo", "hello"]);

Referencing this package makes docker selectable; the module packages need no Docker-specific variant, because a module reaches the backend through the shared abstractions:

PURVIEW_CONTAINERS_BACKEND=docker     # or "auto" (the default) to probe WSLC first, then Docker

Rule	How
Pinned instance	`ContainerBackends.Use(new DockerContainerBackend())`, or `WithBackend(...)`
Named backend	`PURVIEW_CONTAINERS_BACKEND=docker`
Automatic detection	probe every registered backend; WSLC is preferred when it is usable

Requirements

.NET 10 or later, any platform (this package is portable).
A reachable Docker daemon. DockerContainerBackend.GetInfoAsync() pings it and reports the server version, or the reason it could not be reached, so a missing daemon is a clear message and not a timeout deep inside a test.
The daemon must accept the standard Testcontainers configuration (DOCKER_HOST, Docker contexts, ~/.testcontainers.properties). The resource reaper (Ryuk) is used, so a crashed test host does not leak containers.

Behaviour notes

Readiness uses the same shared wait strategies as every other backend (host TCP/HTTP, an in-container command, or a log match), so module behaviour does not change with the backend.
ExecAsync supports WorkingDirectory and Timeout; Environment and EnableStandardInput throw ContainerNotSupportedException rather than being silently ignored.
Log tailing polls the accumulated output until the container stops, because the Testcontainers API exposes no positioned log stream.

Experimental. The public API, defaults and packaging rules can change between prereleases, and there is no production support guarantee. Pin the exact package version you build against.
