Can't set long node name! using kubernetes

[venkateshcontus]

Hi,

we started the ejabberd node with the below command
**sbin/ejabberdctl --node ejabberd@10.0.1.18** 

it works and verified by logs in PSI+ . After that try to check the status getting error. sbin/ejabberdctl --node ejabberd@10.0.1.18 status

IP is created dynamically in kubernetes cluster so we can't able to set in ejabberd.cfg file.

Environment

• ejabberd version: 24.02
• Erlang version: 24
• OS: Linux (Debian)
• Installed from: source

Configuration (only if needed): grep -Ev '^$|^\s*#' ejabberd.yml

loglevel: 4
...

Hello,

Would you be able to edit ejabberdctl script, and see if doing this change:

     # Erlang/OTP 23 or higher: use native dynamic node code
     # https://www.erlang.org/patches/otp-23.0#OTP-13812
-    echo undefined
+    if [ "$ERLANG_NODE" != "${ERLANG_NODE%.*}" ]; then
+      echo "undefined@${ERLANG_NODE#*@}"
+    else
+      echo "undefined"
+    fi

helps with your problem?

@venkateshcontus: Have you seen the @prefiks comment?

Yes, but we can't able to change it on runtime. We are using Kubernetes cluster architecture. So we can't do this change in the ejabberdctl script .

This change was commited as 2c5a8f0860d874e71f7588842d3844b1b76db663. Since this seems to be fixed this problem in my tests, i am closing it.
