You can deploy Fresh to any platform that can run Docker containers. Docker is a tool to containerize projects and portably run them on any supported platform.

When packaging your Fresh app for Docker, it is important that you set the DENO_DEPLOYMENT_IDenvironment variable in your container. This variable needs to be set to an opaque string ID that represents the version of your application that is currently being run. This could be a Git commit hash, or a hash of all files in your project. It is critical for the function of Fresh that this ID changes when any file in your project changes - if it doesn't, incorrect caching will cause your project to not function correctly.

Here is an example Dockerfile for a Fresh project:

FROM denoland/deno:latest

ARG GIT_REVISION
ENV DENO_DEPLOYMENT_ID=${GIT_REVISION}

WORKDIR /app

COPY . .
RUN deno install --allow-scripts
RUN deno task build

EXPOSE 8000

CMD ["deno", "serve", "-A", "_fresh/server.js"]

[info]: The deno install --allow-scripts step is required to populate node_modules and run any post-install scripts needed by npm packages (e.g. Tailwind CSS). This must happen before deno task build.

To build your Docker image inside of a Git repository:

$ docker build --build-arg GIT_REVISION=$(git rev-parse HEAD) -t my-fresh-app .

Then run your Docker container:

$ docker run -t -i -p 80:8000 my-fresh-app

To deploy to a cloud provider, push it to a container registry and follow their documentation.
