alpine 3.9 support

[oadam]

I've been using your build steps with great success for the past few month but I'm having issues adapting it to alpine 3.9 .

The apk install is failing because the libssl1.0 package has been removed :

• https://pkgs.alpinelinux.org/package/v3.8/main/x86/libssl1.0 is working
• https://pkgs.alpinelinux.org/package/v3.9/main/x86/libssl1.0 is not

I tried using libssl1.1 instead but the wkhtmltopdf binary was complaining about missing symbols.

Maybe you can try:

echo 'http://dl-cdn.alpinelinux.org/alpine/v3.8/main' >> /etc/apk/repositories
apk add libssl1.0

Or change to libssl1.1 and libcrypto1.1 since these ones're available - https://pkgs.alpinelinux.org/packages?name=libssl*&branch=v3.9

EDIT1: actually that wouldn't work since the binary was clearly compiled with libssl1.0

EDIT2: check this out https://github.com/Surnet/docker-wkhtmltopdf (includes the build script), i'm gonna contribute a patch for alpine 3.9

EDIT3: There is a PR now - Surnet/docker-wkhtmltopdf#7

@mareksuscak ah well done, nice work

Hm maybe my repository doesn't make sense anymore, since the Surnet approach seems to be way better than my pre-compiled binary copy approach.

Well, the end goal is to support Alpine Linux in the official repository from what I can tell. See wkhtmltopdf/packaging#2

The binary supports alpine 3.10 now (is linked against libssl1.1 and libcrypto1.1). However, I strongly recommend https://github.com/Surnet/docker-wkhtmltopdf
