This is still experimental and shouldn't be used for production builds. If you want to use secrets you should use multi-stage builds. For example:

FROM node:12 as base

FROM base as build
COPY ./keys/id_rsa /root/.ssh/id_rsa
WORKDIR /app
# some private repositories are listed in the dependencies
COPY ./package.json /app/package.json
# install private packages
RUN npm install

FROM base
COPY --from=build /app/node_modules /app/node_modules
Enter fullscreen mode Exit fullscreen mode

Yep, that's a very good method if you are using multistage build. I talk about it here gasparevitta.com/posts/advanced-do...
