Fails to build

[cosmocracy]

I'm unable to build an image from this Dockerfile. Here is an excerpt including the error I get:

...

I'll investigate further but perhaps the packages mentioned are either already included with PHP7 in this distro or have different names?

From inside the base container (PHP7/Apache) it looks like sqlite3 is already a compiled module so perhaps that part of the apt-get in the Dockerfile can be dropped:

docker run -it --rm php:7.0-apache /bin/bash

root@73731ee009fe:/var/www/html# php -m
[PHP Modules]
Core
ctype
curl
date
dom
fileinfo
filter
ftp
hash
iconv
json
libxml
mbstring
mysqlnd
openssl
pcre
PDO
pdo_sqlite
Phar
posix
readline
Reflection
session
SimpleXML
SPL
sqlite3
standard
tokenizer
xml
xmlreader
xmlwriter
zlib

Similarly the image already seems to have pear:

root@73731ee009fe:/var/www/html# pear version
PEAR Version: 1.10.5
PHP Version: 7.0.26
Zend Engine Version: 3.0.0
Running on: Linux 73731ee009fe 4.4.0-89-generic #112-Ubuntu SMP Mon Jul 31 19:38:41 UTC 2017 x86_64

And tinkering with an intermediate container leads me to think GD gets built into PHP7 (or already is) in the base image so that dependency can go, too.

Here is my current Dockerfile which builds fine (yet to test it though). Note that I upgraded the version of SeedDMS.

FROM php:7.0-apache
MAINTAINER Ludwig Prager <ludwig.prager@celp.de>

RUN apt-get update

RUN apt-get install -q -y libpng12-dev imagemagick

RUN docker-php-ext-install gd

RUN chown -R www-data:www-data /var/www/seeddms50x/

RUN touch /var/www/seeddms50x/seeddms-5.0.5/conf/ENABLE_INSTALL_TOOL

Note the elimination of the following apt-get install packages which apparently are part of the latest base image:

• php-pear
• php5-gd
• php5-sqlite

Ok, didn't fully make the pathing changes needed for 5.1.4 but working on that now and will post working Dockerfile shortly :-)

[cosmocracy]

Ok, working fine now. Note that I revised the various PHP/HTTP config files to use the newer 5.x release so that involved straightforward adjustments to the path (and the embedded tar/gzip). I also needed ActiveDirectory/LDAP so those dependencies are included in this build.
