Docker files for deno published on Dockerhub:
- Alpine Linux: hayd/alpine-deno (~23Mb)
- Centos: hayd/centos-deno (~87Mb)
- Debian: hayd/debian-deno (~47Mb)
- Ubuntu: hayd/ubuntu-deno (~48Mb)
The amazonlinux1 build is used to run deno on AWS Lambda.
To run main.ts
from your working directory:
$ docker run -it --init -p 1993:1993 -v $PWD:/app hayd/alpine-deno:1.0.5 --allow-net /app/main.ts
Here, -p 1993:1993
maps port 1993 on the container to 1993 on the host,
-v $PWD:/app
mounts the host working directory to /app
on the container, and
--allow-net /app/main.ts
is passed to deno on the container.
FROM hayd/alpine-deno:1.0.5
EXPOSE 1993 # The port that your application listens to.
WORKDIR /app
# Prefer not to run as root.
USER deno
# Cache the dependencies as a layer (the following two steps are re-run only when deps.ts is modified).
# Ideally cache deps.ts will download and compile _all_ external files used in main.ts.
COPY deps.ts .
RUN deno cache 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 cache main.ts
CMD ["run", "--allow-net", "main.ts"]
and build and run this 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.
