I'm not technically an appdev on here, but that's because I haven't released my VPN Client app yet one Cloudron. I've only converted two apps to Cloudron thus far, but always happy to help grow the community / wealth of apps.

I am looking forward on working on this again, but I noticed to many changes while I had other stuff to do.

If I would now start packaging this I would want to use this
https://github.com/zabbix/zabbix-docker/tree/5.2/zabbix-appliance/rhel

This needs to be ported to Ubuntu since it's rhel.

Is some one from the @appdev team interested in doing this together with me send me message.
(aka. please I don't wanna do this alone again, someone to talk to would be nice! )

That's what I did when building the OpenVPN Client, it was just me mostly with more than 100 comments of brainstorming.

@BrutalBirdie That’s a relief. It’s not too much of a difference from vanilla and it works so that’s awesome! What’s your next challenge to tackle on this project?

Like I noted in my last post, the Frontend for zabbix.

@BrutalBirdie Yeah, best chance is to switch to Postegrl but I def understand you not wanting to do them because then upgrades will be harder to do. I’m the same way.

I personally hate converting the “small container” FROM alpine to Cloudron sometimes because so many DOCKERFILE lines have to be changed since they don’t use the same packaging system. But “small containers” are the new thing so I gotta get used to that when converting to Cloudron.

I got to report something good

The PostgresSQL Version is working fine, it seems like?

That's the server part, will work tomorrow on the Frontend part.

I personally hate converting the “small container” FROM alpine to Cloudron sometimes because so many DOCKERFILE lines have to be changed since they don’t use the same packaging system. But “small containers” are the new thing so I gotta get used to that when converting to Cloudron.

@BrutalBirdie When you make those changes, is there any issues? Cause if not, what’s holding you back from a full 5.0 upgrade? Just switching the database protocol?

Since the Cloudron Base Image is going to stay atubuntu:bionic for awhile according to the devs. Despite Cloudron itself supporting focal in 6.0.

To make things clear, this is the initial packaging of the zabbix-app for cloudron.
It did not work once for now with cloudron.

I want the 5.0.4 LTS Version, on bionic or focal I don't care. But have to use bionic since cloudron base image yada.

@BrutalBirdie Perfect!

So, if you change:

FROM ubuntu:focal
to
FROM ubuntu:bionic

Does Docker itself still build and run it correctly? Cause that would be promising.

To build the official Dockerfile if I change to bionic these changes must be made for a successful build.

Did not try that, but can try.

btw.
I refuse to provide ugly diffs so I abused github now

I will have a look what the diff is compared to focal.

Edit - the answer is not much.

View a of a nice diff.

Keep this local diff - because I will delete my fork later.

My Dockerfile for version 5.0.4:

• https://git.cloudron.io/BrutalBirdie/zabbix-app/-/blob/master/Dockerfile

Dockerfile for 4.4:

• https://github.com/zabbix/zabbix-docker/blob/4.4/server-mysql/ubuntu/Dockerfile

@ruihildt said in Zabbix - Appdev Log:

@BrutalBirdie Zabbix proposes specific build steps for different Ubuntu versions no? If so, changing the Ubuntu target should fix that error.

Yes but sadly their Docker based setups are all based on Ubuntu:focal, see ->
https://github.com/zabbix/zabbix-docker/blob/5.0/server-mysql/ubuntu/Dockerfile

I wonder if they’re based on focal because that’s the latest or if they actually need features from focal. Maybe bionic would work as a target without any changes?

Sorry I just meant is there a way to use an alternative database protocol, but I try to keep original open source code as close to vanilla as possible for updates too. I’ll look into this again. Did you just start packaging it for Cloudron and the Cloudron SQL service is giving you issues?

MySQL and PostgreSQL are supported.

https://www.zabbix.com/download?zabbix=5.0&os_distribution=ubuntu&os_version=18.04_bionic&db=postgresql&ws=nginx

edit:
From Zabbix Docs - https://www.zabbix.com/documentation/current/manual/installation/requirements

MySQL	5.5.62 - 8.0.x	Required if MySQL is used as Zabbix backend database. InnoDB engine is required.
MariaDB (10.0.37 or later) also works with Zabbix.
We recommend using the MariaDB Connector/C library for building server/proxy regardless of whether you use a MySQL or MariaDB database server.

 /usr/sbin/zabbix_server --foreground -c /app/data/zabbix/config/zabbix_server.conf
/usr/sbin/zabbix_server: error while loading shared libraries: libnetsnmp.so.30: cannot open shared object file: No such file or directory

Should be this package, but not existent in cloudron/base:2.0.0 image

libsnmp35

Edit - very simple why libsnmp35 is for focal Ubuntu 20.04 and Cloudron is not based on focal

This is even not taking into account Mysql belonging to Oracle, which has spun of the MariaDB fork.

So yeah, I think you can't go wrong by going with Postgres instead of Mysql.

Would you prefer postgres over mysql?
