That makes sense and looks like fairly minimal change so I'm :+1: BTW we're going to switch to `Ubuntu Bionic` for the Dockerfiles really soon. So your tests and feedback...

WDYT @ytjohn?

@emedvedev answer here is very helpful, so I renamed Issue title for better search. Maybe it worth to move it to separated readme page or even blog. But for now...

I could reproduce it. `ST2_WEBUI_URL` in `st2chatops.env` doesn't work at all. It happens because `st2.conf` [`webui_base_url`](https://github.com/StackStorm/st2/blob/master/conf/st2.package.conf#L57-L58) defaults to current machine [`hostname`](https://github.com/StackStorm/st2/blob/733a0524999de2383901a10678bbaf9e54e44885/st2common/st2common/config.py#L98-L101). And because `webui_base_url` is set, it always takes precedence...

So this is definitely a bug, because `ST2_WEBUI_URL` is noop, just doesn't work in current state. I think there are 2 options: 1) Deprecate `ST2_WEBUI_URL` from `st2chatops.env` to avoid confusion...

@manisha-tanwar Yes, this issue is still actual.

Thanks @sibirajal for opening an issue! So as discussed, the reason behind this behavior, `systemd` by default forwards all the messages from `journalctl` to `syslog`. Depending on `rsyslogd` configuration, duplicated...

- 1. packagecloud does not appear to have the ability to enable gpgcheck (they say it's [somehow tricky](http://blog.packagecloud.io/eng/2014/11/24/howto-gpg-sign-verify-rpm-packages-yum-repositories/). Same with Bintray https://github.com/StackStorm/st2-packages/issues/48) - 2. packagecloud does not appear to have...

Seems now it's possible to import own GPG key for repo, the PackageCloud feature announced in Jun, 2017: https://blog.packagecloud.io/eng/2017/06/08/announcing-package-signing-gpg-key-support/ With this, we can potentially sign the packages during the build...

At the moment, for systemd (CentOS7, Ubuntu16) the only way is: ```sh journalctl --unit=st2chatops ```
