I see the packages in the package list on alpinelinux.org.
https://pkgs.alpinelinux.org/package/main/x86_64/libcurl
https://pkgs.alpinelinux.org/package/testing/x86_64/stunnel

Halp! :smile:

That would be probably better to ask alpine guys. But you can use
apk search libcurl
which shows only curl, I don't know why you can't install only libcurl, but it seems little wierd that on
https://pkgs.alpinelinux.org/package/main/x86_64/curl
is libcurl noted as Dependency and also Subpackage

For stunnel, you can see it is avalaible in testing repository.

Yeah @andyshinn hit me up on Slack. This ended up working for me

FROM alpine:3.3

RUN echo http://dl-cdn.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories
RUN apk update
RUN apk add --update \
    curl \
    stunnel
... snip ...

Ping me in Slack is you need some more help with it. Definitely interested in what you were talking about earlier in regards to Alpine buildpacks and happy to help.
