static-content-lambda

Static content lambda

Because sometimes you just want to host static content inside an AWS lambda.

How it works

All this Go program does is wrap http.FileServer inside an AWS lambda handler that can interpret API Gateway requests, and transforms the response into something API Gateway can return to the browser.

It assumes that the static content is served from /var/www/html, however, that path can be changed with the CONTENT_DIR environment variable.

Usage

The Dockerfile in this repo includes an example of how to use this server with the content located in static_demo, however, in production, you could just download the file binary directly without needing to compile it. This would look something like this:

FROM busybox

ADD https://github.com/cds-snc/static-content-lambda/raw/main/release/latest/lambda-static-server /lambda-static-server
RUN chmod 755 /lambda-static-server

WORKDIR /var/www/html
COPY /content ./

ENTRYPOINT ["/lambda-static-server"]

or, if you want to be super slim

FROM busybox as build

ADD https://github.com/cds-snc/static-content-lambda/raw/main/release/latest/lambda-static-server /lambda-static-server
RUN chmod 755 /lambda-static-server

FROM scratch
COPY --from=build /lambda-static-server /lambda-static-server

WORKDIR /var/www/html
COPY /content ./

ENTRYPOINT ["/lambda-static-server"]
