For example:

$ docker run -it --init -p 1993:1993 -v $PWD:/app hayd/deno:alpine-0.35.0 --allow-net /app/main.ts

or

FROM hayd/deno:alpine-0.35.0

EXPOSE 1993

WORKDIR /app

# Prefer not to run as root.
USER deno

# Cache the dependencies as a layer (this is re-run only when deps.ts is modified).
# Ideally this will download and compile _all_ external files used in main.ts.
COPY deps.ts .
RUN deno fetch deps.ts

# These steps will be re-run upon each file change in your working directory:
ADD . .
# Compile the main app so that it doesn't need to be compiled each startup/entry.
RUN deno fetch main.ts

ENTRYPOINT ["deno", "run", "--allow-net", "main.ts"]

and run locally:

$ docker build -t app . && docker run -it --init -p 1993:1993 app

See example directory.

Note: Dockerfiles provide a USER deno and DENO_DIR is set to /deno-dir/ (which can be overridden).

If running multiple deno instances within the same image you can mount this directory as a shared volume.
