AttributeError: 'module' object has no attribute 'SSLContext'

[rockaut]

I tried to update the Dockerfile to new Zabbix Proxy 3.4.10 as the Version Proxy 3.4.7 isn't compatible to Server 3.4.10.

But i get some python errors on startup, and no vPoller-Worker or Proxy connection after that. Zabbix Proxy is communicating without troubles.

Weird thing is. All i'm changin is the Zabbix Version in Dockerfile:

`FROM 'zabbix/zabbix-proxy-sqlite3:ubuntu-3.4.10'

ENV ZBX_SOURCE_VERSION 3.4.10`

If i leave them at 3.4.7 all works well. So it has to be something with the Zabbix Module i guess.

I may have found it in the old issue #180 ... currently it seems Python 2.7.6 is active in zabbix-proxy image.

[rockaut]

I tried to get it to 2.7.9 but it didn't work. Don't know how to fix that. I opened an Issue in Zabbix Docker Rep as 14.04 is very old now and hope the may update the source image itself.

As a workaround i will try the oder distribution-images

[dnaeon]

What was the issue with 2.7.9?

As you noted already the cause of the exception is an old Python, which is no longer supported.

[rockaut]

I tried to install it from source but got multiple errors. Haven't had much time to completely work it out. Also I have to admit that I really would like to see the source problem fixed which is the old base image of zabbix proxy.

May you please leave that issue open so I can close it with PR after fix.

Sure, will leave it open.

Let me know when you find the root cause. Might also be useful to others to provide a link to the Zabbix proxy issue as well, so we can keep track of it.

Thanks, Marin

You're right: https://github.com/zabbix/zabbix-docker/issues/328

Would help if some vote there too.

[rockaut]

https://github.com/zabbix/zabbix-docker/issues/328 is now fixed. Already have a working new Buildfile - will upload later today.
