PDF/CSV export

[sebek72]

I am having issues with PDF export on icingaweb2 pages (does not work out of the box).
Enabling the PDFexport module google-chrome is needed in the docker image. Can this be added as default to the Dockerfile?

Dokerfile diff
`-RUN ["bash", "-exo", "pipefail", "-c", "export DEBIAN_FRONTEND=noninteractive; apt-get update; apt-get install --no-install-{recommends,suggests} -y apache2 ca-certificates libapache2-mod-php7.4 libldap-common locales-all php-{imagick,redis} php7.4-{bcmath,bz2,common,curl,dba,enchant,gd,gmp,imap,interbase,intl,json,ldap,mbstring,mysql,odbc,opcache,pgsql,pspell,readline,snmp,soap,sqlite3,sybase,tidy,xml,xmlrpc,xsl,zip}; apt-get clean; rm -vrf /var/lib/apt/lists/*"]

+RUN ["bash", "-exo", "pipefail", "-c", "export DEBIAN_FRONTEND=noninteractive; apt-get update; apt-get install --no-install-{recommends,suggests} -y wget apache2 ca-certificates libapache2-mod-php7.4 libldap-common locales-all php-{imagick,redis} php7.4-{bcmath,bz2,common,curl,dba,enchant,gd,gmp,imap,interbase,intl,json,ldap,mbstring,mysql,odbc,opcache,pgsql,pspell,readline,snmp,soap,sqlite3,sybase,tidy,xml,xmlrpc,xsl,zip}; wget -q https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb; apt-get install --no-install-recommends -y ./google-chrome-stable_current_amd64.deb; rm google-chrome-stable_current_amd64.deb; apt-get clean; rm -vrf /var/lib/apt/lists/*"]`

The downside is that the image size jumps from around 700MB to 1.1GB

Hi,

Does Chromium work as well for you?

[sebek72]

Does not reduce the image size.

Now another issue is the CVS export runs out of memory.
Allowed memory size of 134217728 bytes exhausted (tried to allocate 65536 bytes) in /usr/share/icinga-php/ipl/vendor/composer/ClassLoader.php on line 576

[sebek72]

Problem solved by increasing the memory_limit to 256M in docker container php config.
Another problem persists: Icinga/icingadb-web#972

Pro: the module starts the browser by itself, so it has to be in the same image

Cons:

• apt install --no-install-{recommends,suggests} chromium : After this operation, 592 MB of additional disk space will be used.
• One can easily craft a derived image:

FROM icinga/icingaweb2
USER root
RUN ["bash", "-exo", "pipefail", "-c", "export DEBIAN_FRONTEND=noninteractive; apt-get update; apt-get install --no-install-{recommends,suggests} -y chromium; apt-get clean; rm -vrf /var/lib/apt/lists/*"]
USER www-data
