Add Alpine

[holmesb]

Would be cool to add the Alpine thin-Linux distro. Widely-used Docker images are based on this. It uses the APK package manager. Busybox has no package manager so probably trickier\more work.

I've tried this a few times over the years. Since Alpine isn't quite regular Linux, OpenOnload doesn't build on it. Better off sticking to Solarflare's supported Linux distros and making the images smaller (#4).

Here's something to start with if you wanted to play around:

# Dockerfile - Ubuntu Bionic Beaver
#
# Installs Solarflare's OpenOnload into Alpine Linux.
#
# OpenOnload web page:
#    https://www.openonload.org/
#
# To expose the host and onload to this container, run like this:
#
#   docker run --net=host --device=/dev/onload --device=/dev/onload_epoll --device=/dev/onload_cplane -it ONLOAD_ENABLED_IMAGE_ID [COMMAND] [ARG...]
#
# NOTE: The host's OpenOnload version must be the same as the container's.

# Onload package URL and legacy URL

# otherwise it will download the tarball from ONLOAD_LEGACY_URL as before.

# When ONLOAD_WITHZF is non-empty, the build includes Solarflare's TCPDirect library.
# Default is to exclude it.
ARG ONLOAD_WITHZF

# When ONLOAD_DISABLE_SYSCALL_HOOK is non-empty, then the build disables hooking the syscall function from libc.
# Default is empty, enabling the OpenOnload's default hooking the syscall function.
#
# This only works with OpenOnload 201811 and newer.
#
# Some libraries, such as jemalloc need to invoke syscalls at startup.
# This can cause infinite loops because the OpenOnload acceleration also needs malloc (via dlsym)

ARG ONLOAD_DISABLE_SYSCALL_HOOK

# When ONLOAD_USERSPACE_ID is non-empty, it sets the userspace build md5sum ID.
# Default is empty, using the actual build md5sum ID
#
# This is necessary when the OpenOnload build is patched (for example with ONLOAD_DISABLE_SYSCALL_HOOK).
# The OpenOnload system checks for version and ID matches between userspace and the driver;
# thus one may need to spoof the userspace ID.
ARG ONLOAD_USERSPACE_ID

# 1) Install OpenOnload build dependencies
# 2) Download and verify OpenOnload from Solarflare's site
# 3) Extract, build, and install onload
# 4) Cleanup

Closing as wontfix unless upstream adds support for Alpine.
