Use the official Bun image to run the application

FROM oven/bun:latest

Copy the package.json and bun.lock into the container

COPY package.json bun.lock ./

Install the dependencies

RUN bun install --production --frozen-lockfile

Copy the rest of the application into the container

COPY . .

Run the application

CMD ["bun", "index.ts"]


Make sure that the start command corresponds to your application’s entry point. This can also be `CMD ["bun", "run", "start"]` if you have a start script in your `package.json`.This image installs dependencies and runs your app with Bun inside a container. If your app doesn’t have dependencies, you can omit the `RUN bun install --production --frozen-lockfile` line.

Create a new `.dockerignore` file in the root of your project. This file contains the files and directories that should be _excluded_ from the container image, such as `node_modules`. This makes your builds faster and smaller:

.dockerignore

node_modules Dockerfile* .dockerignore .git .gitignore README.md LICENSE .vscode .env

Any other files or directories you want to exclude

Deploy your service

Make sure you’re in the directory containing your `Dockerfile`, then deploy directly from your local source:

Update the `--region` flag to your preferred region. You can also omit this flag to get an interactive prompt to select a region.

terminal

gcloud run deploy my-bun-app --source . --region=us-west1 --allow-unauthenticated

Deploying from source requires an Artifact Registry Docker repository to store built containers. A repository named [cloud-run-source-deploy] in region [us-west1] will be created.
