Get Started with DBOS

Deploy Your First App to the Cloud​

Using the CLI?

1. Initialize your application​

Create a folder for your app with a virtual environment, then enter the folder and activate the virtual environment. Next, install dbos and initialize your folder with a sample application.

You can choose another name for your app. Names should be 3 to 30 characters long and contain only lowercase letters and numbers, dashes, and underscores.

python3 -m venv my-app/.venv
cd my-app
source .venv/bin/activate
pip install dbos
dbos init

2. Install the DBOS Cloud CLI​

The Cloud CLI requires Node.js 20 or later.

Instructions to install Node.js

Run the following commands in your terminal:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

nvm install 22
nvm use 22

Run this command to install it.

npm i -g @dbos-inc/dbos-cloud@latest

3. Deploy to DBOS Cloud!​

First, run pip freeze to create a requirements file specifying your app's dependencies. Then, run dbos-cloud app deploy to deploy your app to DBOS Cloud. Follow the prompts to sign in and to provision a Postgres database server on the cloud.

pip freeze > requirements.txt
dbos-cloud app deploy

In less than a minute, it should print Access your application at <URL>. To see that your app is working, visit <URL> in your browser.

https://<username>-my-app.cloud.dbos.dev

Welcome to DBOS!

Congratulations, you've successfully deployed your first app to DBOS Cloud! You can see your deployed app in the cloud console.

1. Find a Template​

From https://console.dbos.dev/launch, select the template you'd like to deploy. When prompted, create a database for your app with default settings.

Not sure which template to use? We recommend the DBOS Web App Starter.

2. Connect to GitHub​

To ensure you can easily update your project after deploying it, DBOS will create a GitHub repository for it. You can deploy directly from that GitHub repository to DBOS Cloud.

First, sign in to your GitHub account. Then, set your repository name and whether it should be public or private.

Deploy with GitHub

3. Deploy to DBOS Cloud​

Click "Create GitHub Repo and Deploy" and DBOS will clone a copy of the source code into your GitHub account, then deploy your project to DBOS Cloud. In less than a minute, your app should deploy successfully.

Congratulations, you've successfully deployed your first app to DBOS Cloud!

4. View Your Application​

At this point, your app is serverlessly deployed, with its very own URL assigned. If you continue to your application page, you can click on the URL to see your application live on the Internet.

Application page

To start building, edit your application on GitHub (for the web app starter, source code is in app/main.py), commit your changes, then press "Deploy From GitHub" to see your changes reflected in the live application.

Run Your App Locally​

1. Git Clone Your Application​

Clone your application from git and enter its directory.

git clone <your-git-url> my-app
cd my-app

2. Set up a Virtual Environment​

Create a virtual environment and install dependencies.

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

3. Start Your App​

Now, start your app!

dbos start
http://localhost:8000/
