BTW, there's a long list of symbols missing from OpenSSL, I just included the first one.

I need a little more clarification. You are saying that after running smith on a host that the commands on the host are broken? That is highly unexpected. Does it appear that libssl.so is being deleted or overwritten somehow?

It would also be worth running smith with the -v option to see if any of the debug statements report doing something that looks fishy like overwriting files it shouldn't be.

Also, it would be helpful if you could list complete reproduction steps so that I can try to replicate. i.e. how are you building smith? how are you building your alpine container etc. I have been planning to try running smith inside a container but I have not experimented with it yet.

Based on your issue, @jacob-carlborg, it seems you built a Docker image that has Smith inside. If that's what you did, post the Dockerfile you wrote to build the image.

I'm working on setting up a reproducible test.

I haven't been able to create a full working example because smith has some issues downloading my Docker image. But this is what I've got: the problem seems to be related to running smith inside an Alpine based Docker image and using smith to build a micro container based on Alpine that contains wget.
Dockerfile:
FROM golang:1.9-alpine
RUN apk add git make --update
RUN git clone https://github.com/oracle/smith
RUN cd smith && make install && cd ..
ADD smith.yaml /go
RUN ls
RUN smith
RUN lssmith.yaml:
package: https://registry-1.docker.io/library/jacobcarlborg/docker-alpine-wget
paths:
- /etc/issueDocker image used by smith: https://hub.docker.com/r/jacobcarlborg/docker-alpine-wget.

Can you please provide full log of your docker build command for this Dockerfile?

thanks for these steps. I will try to reproduce and see how far I get

For some reason I got a different error now. As I mentioned, smith fails to fetch the Docker image from the public docker registry so I had to use my private one.

Ok I've reproduced the error and I'm looking into it. Btw the reason you couldn't download from dockerhub is you have an extra "library" in the url. It should be: https://registry-1.docker.io/jacobcarlborg/docker-alpine-wget

it looks like somehow /bin/busybox is being replaced with wget which is very odd. I'm still investigating how that might happen

Aha, I thought library was part of the base URL. I just followed the examples here [1] [2].
