I tried to install Zabbix-server-mysql on genuine centos image in docker container:

[root@desktop]# docker run --rm -ti centos:latest /bin/bash

[root@0e4f336ff674]# rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

[root@0e4f336ff674]# rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm

[root@0e4f336ff674]# yum install http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-server-mysql-3.2.3-1.el7.x86_64.rpm

This manual:
https://www.zabbix.com/documentation/3.2/manual/installation/install_from_packages/server_installation_with_mysql requires a file "/usr/share/doc/zabbix-server-mysql-3.2.3/create.sql.gz" to be created during the installation due to its necessity to create zabbix DB on MySQL server. But this file appears missing:

[root@0e4f336ff674]# ls -ld /usr/share/doc/zabbix-server-mysql-3.2.3/create.sql.gz

ls: cannot access /usr/share/doc/zabbix-server-mysql-3.2.3/create.sql.gz: No such file or directory

The funny part is this file actually EXISTS in *.rpm file:

[root@0e4f336ff674]# rpm2cpio http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-server-mysql-3.2.3-1.el7.x86_64.rpm | cpio -t | grep create

./usr/share/doc/zabbix-server-mysql-3.2.3/create.sql.gz

Moreover, the package doesn't seem to have any pre- or post-install scripts that could delete the /usr/share/doc/zabbix-server-mysql-3.2.3/ directory:

[root@0e4f336ff674]# rpm -qp --scripts http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-server-mysql-3.2.3-1.el7.x86_64.rpm

preinstall scriptlet (using /bin/sh):

getent group zabbix > /dev/null || groupadd -r zabbix

getent passwd zabbix > /dev/null || 

    useradd -r -g zabbix -d /var/lib/zabbix -s /sbin/nologin 

    -c "Zabbix Monitoring System" zabbix

:

postinstall scriptlet (using /bin/sh):



if [ $1 -eq 1 ] ; then 

        # Initial installation 

        /usr/bin/systemctl preset zabbix-server.service >/dev/null 2>&1 || : 

fi 

/usr/sbin/update-alternatives --install /usr/sbin/zabbix_server 

    zabbix-server /usr/sbin/zabbix_server_mysql 10

:

So what could be the problem with it?

P.S.: I am aware of the exising official zabbix-on-docker images: github.com/zabbix/zabbix-docker

May be it blocks on "systemctl preset" because in a systemd-controlled operating system that one tries to talk to the systemd daemon to execute the command. However in a docker container there is no systemd daemon.

You could try to avoid that potential problem by using the https://github.com/gdraheim/docker-systemctl-replacement to execute the "systemctl preset".

According to https://github.com/tianon/docker-brew-ubuntu-core/issues/122, you should add this to the top of the Dockerfile:

# Do not exclude man pages & other documentation

RUN rm /etc/dpkg/dpkg.cfg.d/excludes

I couldn't figure out a way to get the create.sql.gz file to install while running inside a Docker CentOS 7 container (even though I can start it with systemd running properly), but I did the following workaround:

wget https://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/4.2.6/zabbix-4.2.6.tar.gz/download

mv download download.tar.gz

tar -xzvf download.tar.gz

cd zabbix-4.2.6/database/mysql

mysql -uzabbix -p[password] zabbix < schema.sql

mysql -uzabbix -p[password] zabbix < images.sql

mysql -uzabbix -p[password] zabbix < data.sql

And then I could finish the frontend installation of Zabbix.

Annoying, but it worked and was the only way I could get this going without being able to source a create.sql.gz file from anywhere else.
