Support Alpine

[wernight]

The direction is going towards using Docker, and on Docker the direction is towards using Alpine base images (because they're smaller), and most main packages now support Alpine (Nginx included).

It seems that it almost compiles on alpine:edge. I got past the traceback by installing libunwind@testing package but some missing references remain:

It's worth finding how to make it compile and document it.

Just to make sure: are you building psol.a yourself?

[wernight]

Yes, I did (following mostly https://developers.google.com/speed/pagespeed/module/build_ngx_pagespeed_from_source#dependencies):

Dockerfile:

FROM alpine:edge

RUN set -x && \
    echo "@testing http://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories && \
    apk add --update ca-certificates curl g++ libunwind@testing && \

    cd /tmp && \
    NPS_VERSION=1.11.33.0 && \
    curl -L https://github.com/pagespeed/ngx_pagespeed/archive/release-${NPS_VERSION}-beta.zip -o release-${NPS_VERSION}-beta.zip && \
    unzip release-${NPS_VERSION}-beta.zip && \
    cd ngx_pagespeed-release-${NPS_VERSION}-beta/ && \
    curl -L https://dl.google.com/dl/page-speed/psol/${NPS_VERSION}.tar.gz | tar -xzv && \

    cd /tmp && \
    NGINX_VERSION=1.8.1 && \
    curl -L http://nginx.org/download/nginx-${NGINX_VERSION}.tar.gz | tar -xvz  && \
    cd nginx-${NGINX_VERSION}/ && \
    ./configure --add-module=/tmp/ngx_pagespeed-release-${NPS_VERSION}-beta

Then looking at objs/autoconf.err for errors.

[morlovich]

curl -L https://dl.google.com/dl/page-speed/psol/${NPS_VERSION}.tar.gz
| tar -xzv &&

^^^

This bit is grabbing psol.a as a binary, which is not really workable
with a non-glibc system.

Sadly you near certainly need to hand-build psol.a for your system the
longer and more complicated way:
https://github.com/pagespeed/ngx_pagespeed/wiki/Building-PSOL-From-Source

(That probably expects BRANCH to be set...)

Sounds legit. My point is that a documentation for Alpine would be very welcome because it's where I think the near future lives.

Ideally it'd also be package of Alpine.

[cchamplin]

@wernight Preliminary work to get this created as an Alpine package is available here https://github.com/cchamplin/alpine-ngx-pagespeed. There is still several things that need to happen before I'll start going through the process of submitting to the Alpine repos. Most importantly is that I need it tested on fresh alpine installs.

Ideally we'd also see psol updated at some point to use modern versions of libpng so that we don't have to package an ancient copy of libpng12.

[wernight]

To test it, just use docker run --rm -it alpine. You can specify which version of Alpine you want to run as well. That would be very fast. If you don't have Docker, simply run curl -fsSL https://get.docker.com/ | sh and that should be it.

[nikolay]

This is super important to have in place! By the way, v3.4.0 is out1

[wernight]

Can't you just test on Docker? That should be simple. docker run --rm -it
alpine

I'm running https://github.com/cchamplin/alpine-ngx-pagespeed on fresh Alpine for some time now without real issues, however it seems to be not maintained.

I see 3 places that would potentially welcome PageSpeed for Nginx on Linux Alpine:

• PageSpeed itself: Document how to build
• Linux Alpine: Package
• Docker Nginx image (quite unlikely)

I agree it'd be easier if we could use a modern libpng.

[wernight]

I've a working updated Dockerfile that builds Nginx + PageSpeed if anyone is interested. It's IMO better formatted than wunderkraut/alpine-nginx-pagespeed, very slow to build, but working.

[iler]

@wernight we (Wunderkraut) would like to work together with this task to get a working version out for everyone. We had a pause in our internal development with this but have now continued with this and would like to cooperate with the effort.
