Include bcrypt in base image about ansible-silo HOT 2 CLOSED

As always, sorry for the delay...

I'm not in general against adding bcrypt to the base image. The problem here lies more in the apline packages, which only are available in their latest version - the reason why the base image exists in the first place. When building a new base image all package versions would need to be updated to the latest available, which at very least would bring Silo to version 3. We can add bcrypt later when we need to re-build the base image for other reasons.

But, good news! The solution for your problem is actually quite simnple.

If you need bcrypt in general, you can install it like this:

1. Open a shell

   ansible-silo --shell

2. Install build requiremtns

   sudo apk add --no-cache gcc libffi-dev python2-dev musl musl-dev musl-utils

3. Install bcrypt

   pip install bcrypt>=3.1.3

No need to clean up behind you. All files created by apk add will not persist when the container exits. pip, though, is configured to install into your docker volume in /silo/userspace/lib and therefore will be available in all ansible calls later on.

Silo bundles don't use volumes. If you need bcrypt in a bundle you need to add the installation instructions to your Dockerfile like so:

RUN apk add --no-cache gcc \
                       libffi-dev \
                       python2-dev \
                       musl \
                       musl-dev \
                       musl-utils && \
    pip install bcrypt>=3.1.3 && \
    apk del --no-cache gcc \
                       libffi-dev \
                       python2-dev \
                       musl-dev

Does this help?

I'll leave this ticket open as this should get better documented.

Similar to issue #54:

I've been able to solve this by rebuilding grpn/ansible-silo-base:3.0.0 and grpn/ansible-silo:3.0.0.
I'm still working through some issues, but when I'm ready, I will submit a PR.
