certificate error with Go HTTP client in alpine Docker

Using the Go HTTP client from a alpine docker image will result in this error – x509: failed to load system roots and no roots provided

Solution: alpine is a minimal image, hence CA certificates are required. You add that in the Dockerfile as per below example

FROM alpine 

RUN apk add --no-cache ca-certificates 

COPY my-app .

CMD ["./my-app"]

Got this hint from the golang alpine Dockerfile

Cheers!
