deno_docker
Docker files for Deno published on Dockerhub:
- Alpine Linux: denoland/deno:alpine

- Debian: denoland/deno:debian (default)
- Distroless: denoland/deno:distroless
- Ubuntu: denoland/deno:ubuntu
- Only the binary: denoland/deno:bin
Run locally
To start the deno
repl:
$ docker run -it denoland/deno:1.25.4 repl
To shell into the docker runtime:
$ docker run -it denoland/deno:1.25.4 sh
To run main.ts
from your working directory:
$ docker run -it -p 1993:1993 -v $PWD:/app denoland/deno:1.25.4 run --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.
As a Dockerfile
FROM denoland/deno:1.25.4
# The port that your application listens to.
EXPOSE 1993
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 -p 1993:1993 app
Using your own base image
If you prefer to install deno
in your own base image, you can use the
denoland/deno:bin
to simplify the process.
ARG DENO_VERSION=1.25.4
FROM denoland/deno:bin-$DENO_VERSION AS deno
FROM ubuntu
COPY --from=deno /deno /usr/local/bin/deno
(optional) Add deno
alias to your shell
Alternatively, you can add deno
command to your shell init file (e.g.
.bashrc
):
deno () {
docker run \
--interactive \
--tty \
--rm \
--volume $PWD:/app \
--volume $HOME/.deno:/deno-dir \
--workdir /app \
denoland/deno:1.25.4 \
"$@"
}
and in your terminal
$ source ~/.bashrc
$ deno --version
$ deno run ./main.ts
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.
Thanks
Thanks to Andy Hayden for maintaining and setting up these images.
