How to host Strapi using distroless image in Docker without using npm command?

I am trying to host a Strapi instance in a Docker container using a distroless image. As I am using a distroless image, I cannot use the npm command to run Strapi. Is there an equivalent of the strapi start command that can be run purely using Node?

Here is my summarised Dockerfile:

FROM node:16-alpine as build
# Build steps
# ...

FROM gcr.io/distroless/nodejs:16 as host
WORKDIR /opt/app
COPY --from=build /opt/app ./
EXPOSE 1337
CMD ["yarn", "start"]

As I mentioned, this Dockerfile cannot be used with a distroless image since it uses npm command in the CMD line. What changes should I make to my Dockerfile to use Strapi with a distroless image without using the npm command?

Solution

  • So the right path is ./node_modules/@strapi/strapi/bin/strapi.js

    Here's the updated Dockerfile

    FROM gcr.io/distroless/nodejs:16 as host
WORKDIR /opt/app
COPY --from=build /opt/app ./
EXPOSE 1337
CMD ["./node_modules/@strapi/strapi/bin/strapi.js", "start"]

    Take note that you should not use alpine to build the application when you are using distroless. Use the node base image.

    FROM node:16.20 as build
