RustFS integration in the AppHost

⭐ Community Toolkit

The RustFS hosting package runs the rustfs/rustfs:1.0.0 container. For an overview, see Get started with the RustFS integration.

Add a RustFS resource

AddRustFs adds the S3-compatible object store and the console endpoint. It creates access-key and secret-key parameters when you do not provide your own. Aspire assigns host ports unless you choose ports in AddRustFs.

TypeScript

apphost.mts

import { createBuilder } from './.aspire/modules/aspire.mjs';

const builder = await createBuilder();

const rustfs = await builder.addRustFs('rustfs');
await rustfs.withDataVolume();

const api = await builder.addNodeApp('api', './api', 'index.js');
await api.withReference(rustfs);

await builder.build().run();

C#

AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var rustfs = builder.AddRustFs("rustfs")
    .WithDataVolume();

builder.AddProject<Projects.Api>("api")
    .WithReference(rustfs);

// After adding all resources, run the app...
builder.Build().Run();

The resource exposes the S3 API on container port 9000 and the console on container port 9001. Host ports are allocated by Aspire by default. port and consolePort on AddRustFs let you select fixed host ports.

Configure credentials and ports

Pass AppHost parameter resources to AddRustFs when you need explicit credentials. Leave port and consolePort unset to use dynamically assigned host ports:

TypeScript

apphost.mts

import { createBuilder } from './.aspire/modules/aspire.mjs';

const builder = await createBuilder();

const accessKey = await builder.addParameter('rustfs-access-key', {
  secret: true,
});
const secretKey = await builder.addParameter('rustfs-secret-key', {
  secret: true,
});
const rustfs = await builder.addRustFs('rustfs', {
  accessKey,
  secretKey,
  port: 9000,
  consolePort: 9001,
});
await rustfs.withDataVolume();

await builder.build().run();

C#

AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var accessKey = builder.AddParameter("rustfs-access-key", secret: true);
var secretKey = builder.AddParameter("rustfs-secret-key", secret: true);

var rustfs = builder.AddRustFs(
        "rustfs",
        accessKey: accessKey,
        secretKey: secretKey,
        port: 9000,
        consolePort: 9001)
    .WithDataVolume();

// After adding all resources, run the app...
builder.Build().Run();

If you omit either parameter, the integration generates a password parameter for that key. Do not use a fixed host port if another process may already be listening on it.

Nota

Use the generated credentials for local development or provide secret parameters from your chosen secret provider. The connection string contains both values for the dependent app.

Persist data

Use WithDataVolume to keep RustFS data outside the container lifecycle. Aspire creates a named Docker volume unless you provide a name:

TypeScript

apphost.mts

import { createBuilder } from './.aspire/modules/aspire.mjs';

const builder = await createBuilder();

const rustfs = await builder.addRustFs('rustfs');
await rustfs.withDataVolume('rustfs-data');

await builder.build().run();

C#

AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var rustfs = builder.AddRustFs("rustfs")
    .WithDataVolume("rustfs-data");

// After adding all resources, run the app...
builder.Build().Run();

Use WithDataBindMount to mount a host directory at /data when you need direct access to files during development:

TypeScript

apphost.mts

import { createBuilder } from './.aspire/modules/aspire.mjs';

const builder = await createBuilder();

const rustfs = await builder.addRustFs('rustfs');
await rustfs.withDataBindMount('./data/rustfs');

await builder.build().run();

C#

AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var rustfs = builder.AddRustFs("rustfs")
    .WithDataBindMount("./data/rustfs");

// After adding all resources, run the app...
builder.Build().Run();

Volumes persist data without coupling it to a host directory path. Bind mounts make the host directory directly accessible to the container.

Provision buckets

Call AddBucket to register a child resource for one bucket. Aspire waits until the RustFS parent is ready, then issues a signed S3 PUT request to create the bucket. A bucket that already exists is treated as ready. The child resource appears in the dashboard and exposes its own connection string with a Bucket property.

TypeScript

apphost.mts

import { createBuilder } from './.aspire/modules/aspire.mjs';

const builder = await createBuilder();

const rustfs = await builder.addRustFs('rustfs');
await rustfs.withDataVolume();
const images = await rustfs.addBucket('images');
const documents = await rustfs.addBucket('documents');

const api = await builder.addNodeApp('api', './api', 'index.js');
await api.withReference(images);
await api.withReference(documents);

await builder.build().run();

C#

AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var rustfs = builder.AddRustFs("rustfs")
    .WithDataVolume();
var images = rustfs.AddBucket("images");
var documents = rustfs.AddBucket("documents");

builder.AddProject<Projects.Api>("api")
    .WithReference(images)
    .WithReference(documents);

// After adding all resources, run the app...
builder.Build().Run();

Use the list overload to add several buckets while keeping the parent builder for further configuration. The TypeScript method name for this overload is addBuckets:

TypeScript

apphost.mts

import { createBuilder } from './.aspire/modules/aspire.mjs';

const builder = await createBuilder();

const rustfs = await builder.addRustFs('rustfs');
await rustfs.addBuckets(['images', 'documents', 'audit-log']);

await builder.build().run();

C#

AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var rustfs = builder.AddRustFs("rustfs")
    .AddBucket(["images", "documents", "audit-log"]);

// After adding all resources, run the app...
builder.Build().Run();

Configure the signing region

Bucket provisioning uses AWS Signature Version 4 with the default signing region us-east-1. Call WithSigningRegion when your RustFS setup expects another region:

TypeScript

apphost.mts

import { createBuilder } from './.aspire/modules/aspire.mjs';

const builder = await createBuilder();

const rustfs = await builder.addRustFs('rustfs');
await rustfs.withSigningRegion('ap-northeast-1');
await rustfs.addBucket('images');

await builder.build().run();

C#

AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var rustfs = builder.AddRustFs("rustfs")
    .WithSigningRegion("ap-northeast-1")
    .AddBucket("images");

// After adding all resources, run the app...
builder.Build().Run();

Hosting integration health checks

The integration configures an HTTP health check against /health on the primary S3 endpoint and expects HTTP 200. Bucket provisioning waits for the RustFS resource’s ready event before making its signed request. If provisioning fails, the child bucket resource reports the error in the dashboard.

Connection properties

Reference the RustFS resource to pass a connection string with Endpoint, AccessKey, and SecretKey to a dependent app. The value is formatted as Endpoint=http://{host}:{port};AccessKey={key};SecretKey={secret}. A bucket resource adds Bucket={bucketName}. The resource also exposes the Host, Port, AccessKey, SecretKey, and Uri properties. The console endpoint is visible in the dashboard but is not part of the S3 connection string.

For S3 client configuration, see Connect to RustFS.

Exported AppHost API

• AddRustFs(name, accessKey, secretKey, port, consolePort) adds the container and its two endpoints.
• WithDataVolume(name) mounts a Docker volume at /data.
• WithDataBindMount(source) binds a host directory at /data.
• WithSigningRegion(region) sets the SigV4 region used when creating buckets.
• AddBucket(bucketName) adds one child bucket resource; the TypeScript method is addBucket.
• AddBucket(bucketNames) adds multiple child resources; the TypeScript method is addBuckets.
