Crate docker_wrapper 

docker-wrapper

A type-safe Docker CLI wrapper for Rust.

This crate provides an idiomatic Rust interface to the Docker command-line tool. All commands use a builder pattern and async execution via Tokio.

Quick Start

use docker_wrapper::{DockerCommand, RunCommand, StopCommand, RmCommand};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Run a container
    let container = RunCommand::new("nginx:alpine")
        .name("my-nginx")
        .port(8080, 80)
        .detach()
        .execute()
        .await?;

    println!("Started: {}", container.short());

    // Stop and remove
    StopCommand::new("my-nginx").execute().await?;
    RmCommand::new("my-nginx").execute().await?;

    Ok(())
}

Core Concepts

The DockerCommand Trait

All commands implement DockerCommand, which provides the execute() method. You must import this trait to call .execute():

use docker_wrapper::DockerCommand; // Required for .execute()

Builder Pattern

Commands are configured using method chaining:

RunCommand::new("alpine")
    .name("my-container")
    .env("DATABASE_URL", "postgres://localhost/db")
    .volume("/data", "/app/data")
    .port(3000, 3000)
    .memory("512m")
    .cpus("0.5")
    .detach()
    .rm()  // Auto-remove when stopped
    .execute()
    .await?;

Error Handling

All commands return Result<T, docker_wrapper::Error>:

match RunCommand::new("nginx").detach().execute().await {
    Ok(id) => println!("Started: {}", id.short()),
    Err(Error::CommandFailed { stderr, .. }) => {
        eprintln!("Docker error: {}", stderr);
    }
    Err(e) => eprintln!("Error: {}", e),
}

    LogsCommand,     // docker logs
    InspectCommand,  // docker inspect
    TopCommand,      // docker top
    StatsCommand,    // docker stats
    PortCommand,     // docker port

};

Container Operations

use docker_wrapper::{
    DockerCommand,
    ExecCommand,     // docker exec
    AttachCommand,   // docker attach
    CpCommand,       // docker cp
    WaitCommand,     // docker wait
    RenameCommand,   // docker rename
    UpdateCommand,   // docker update
    CommitCommand,   // docker commit
    ExportCommand,   // docker export
};

    ImagesCommand,   // docker images
    PullCommand,     // docker pull
    PushCommand,     // docker push
    BuildCommand,    // docker build

    LoadCommand,     // docker load
    ImportCommand,   // docker import
    HistoryCommand,  // docker history
    SearchCommand,   // docker search
};

Networks and Volumes

use docker_wrapper::{
    DockerCommand,
    NetworkCreateCommand, NetworkLsCommand, NetworkRmCommand,
    VolumeCreateCommand, VolumeLsCommand, VolumeRmCommand,
};

System

use docker_wrapper::{
    DockerCommand,
    VersionCommand,  // docker version
    InfoCommand,     // docker info
    EventsCommand,   // docker events
    LoginCommand,    // docker login
    LogoutCommand,   // docker logout
    SystemDfCommand, // docker system df
    SystemPruneCommand, // docker system prune
};

Feature Flags

compose - Docker Compose Support

docker-wrapper = { version = "0.8", features = ["compose"] }

use docker_wrapper::{DockerCommand, compose::{ComposeUpCommand, ComposeDownCommand, ComposeCommand}};

// Start services
ComposeUpCommand::new()
    .file("docker-compose.yml")
    .detach()
    .execute()
    .await?;

// Stop and clean up
ComposeDownCommand::new()
    .volumes()
    .execute()
    .await?;

templates - Pre-configured Containers

docker-wrapper = { version = "0.8", features = ["templates"] }

Templates provide ready-to-use configurations for common services:

use docker_wrapper::{RedisTemplate, Template};

let redis = RedisTemplate::new("my-redis")
    .port(6379)
    .password("secret")
    .with_persistence("redis-data");

let id = redis.start().await?;
// ... use Redis ...
redis.stop().await?;

Available templates:

• RedisTemplate, RedisSentinelTemplate, RedisClusterTemplate
• PostgresTemplate, MysqlTemplate, MongodbTemplate
• NginxTemplate

swarm - Docker Swarm Commands

docker-wrapper = { version = "0.8", features = ["swarm"] }

manifest - Multi-arch Manifest Commands

docker-wrapper = { version = "0.8", features = ["manifest"] }

Streaming Output

For long-running commands, stream output in real-time:

use docker_wrapper::{BuildCommand, StreamHandler, StreamableCommand};

let result = BuildCommand::new(".")
    .tag("my-app:latest")
    .stream(StreamHandler::print())
    .await?;

if result.is_success() {
    println!("Build complete!");
}

Checking Docker Availability

use docker_wrapper::ensure_docker;

let info = ensure_docker().await?;
println!("Docker {}.{}.{}", info.version.major, info.version.minor, info.version.patch);

Why docker-wrapper?

This crate wraps the Docker CLI rather than calling the Docker API directly (like bollard).

docker-wrapper advantages:

• Just needs docker in PATH (no socket access required)
• Native docker compose support
• Works with Docker, Podman, Colima, and other Docker-compatible CLIs
• Familiar mental model if you know Docker CLI

bollard advantages:

• Direct API calls (no process spawn overhead)
• Lower latency for high-frequency operations
• No external binary dependency

Choose docker-wrapper for CLI tools, dev tooling, Compose workflows, or when working with Docker alternatives.

Choose bollard for high-performance services with many Docker operations.
