A Dockerfile that fits
The Dockerfile below listens on $PORT, runs as non-root and writes only to /tmp, the rules the platform checks.
Rust (Axum) deploy guide · Agent Lab Deploy
Deploy Rust (Axum)
in one sentence.
Add the Dockerfile below to your Rust (Axum) project — or tell Claude Code, Codex or Cursor "deploy this". Agent Lab builds it into a web service, gives every version a preview URL with rollback, and checks uploads for leaked keys. Apps and databases run on Google Cloud in Taiwan.

Why deploy Rust (Axum) on Agent Lab
Rust (Axum) online without running a server yourself
Rust project, built from a Dockerfile, deployed as a web service.
Preview, go live, roll back
Every upload is a new version with its own URL. Look first, then go live; switch back to any version in one click.
Leaked keys caught
Uploads are checked for API keys and credentials before they can go live. Secrets go in the console, never in the code.
PostgreSQL in one click
Create a database and connect it; the connection is written into the app's environment and the password is never shown.
Your options
Rust (Axum) on Agent Lab, or on your own VPS
Scroll the table sideways.
| What you care about | Agent Lab Deploy | Your own VPS |
|---|---|---|
| Setup | Upload with the Dockerfile below, or say one sentence | SSH, a runtime, a process manager, a reverse proxy |
| HTTPS and domains | Automatic, custom domains on paid plans | Certbot and DNS by hand |
| Preview and rollback | Every version has its own URL; roll back in one click | Write your own scripts |
| Before going live | Uploads checked for leaked keys | Nothing unless you set it up |
| Database | PostgreSQL in one click, connection written into the app | Install and back it up yourself |
| Cost to start | Free plan: NT$0, one size-S app (sleeps when idle) | A VPS at roughly NT$200–600 a month, plus your time |
Steps
Deploy Rust (Axum) in four steps
Prepare
Add the Dockerfile below at the top of the project and replace the placeholder names.
Upload or ask
Drop the folder on a project's Deploy tab, push from GitHub, or ask your AI tool through Agent Lab MCP.
Build and check
The platform builds the version and checks it for leaked keys. Enter any secrets it lists in Settings.
Preview and go live
The first version goes live once it builds. Later ones get a preview URL; go live when you're happy.
Setup
A Rust (Axum) Dockerfile
Replace myapp with the package name in Cargo.toml; Actix Web and Rocket work the same way as long as they listen on 0.0.0.0:$PORT. Install ca-certificates in the second stage, or outbound HTTPS calls fail.

Or ask your AI tool
Read https://app.agentlab.cresclab.com/agent/deploy.md and deploy this Rust (Axum) project to Agent Lab using the Dockerfile at the top. Show me the build plan and the environment variables it needs first, tell me where to enter any secrets, and wait for my OK before it goes live.FAQ
Deploying Rust (Axum): questions
Do I need a Dockerfile to deploy Rust (Axum)?
Yes. Agent Lab builds Rust (Axum) from the Dockerfile at the top of the project; the one on this page meets the platform's rules (listen on $PORT, linux/amd64, write only to /tmp). Docs →
Rust builds are slow; what helps?
Copy Cargo.toml and Cargo.lock first and build the dependencies, then copy the source, so dependencies are cached. Or build the image locally or in CI and push it to your organization's registry.
Where do API keys and other secrets go?
In the project's Settings, under Secrets; the code reads them as environment variables. Random values such as session secrets can be generated in the console without anybody seeing them. A key found in an upload stops it before it goes live.
Can I deploy Rust (Axum) from Claude Code or Codex?
Yes. Connect Agent Lab MCP once (one command, sign in in the browser, no API key), then say "deploy this Rust (Axum) app". The tool creates the project, uploads, waits for the build and asks before going live. Connect MCP →
Is there a free way to host Rust (Axum)?
The Free plan is NT$0: one size-S app that sleeps after 15 idle minutes, one size-S database, three static web pages, 100 build minutes and 5 GB of traffic a month, pausing at the limit instead of charging. Pro (US$29 a month before tax) keeps apps running and adds custom domains. Pricing →
