HOST_OS = "unraid" env var, how about HOST_HOSTNAME = $HOSTNAME?

[Meles Meles]

Very handily the docker code automatically creates a HOST_OS = "unraid" env var in each container, can we make it automatically create a HOST_HOSTNAME = $HOSTNAME (i.e. the unraid server's hostname) as well? 

 

and yes, i know i can just do it in "Extra Parameters" for each container - but it'd be handy to have it there automatically. 

 

-e HOST_HOSTNAME=$HOSTNAME

 

 

making the container name available within all containers would probably be useful too.....

Because I was interested to have a play (and just for S&G), i've modded my /usr/local/emhttp/plugins/dynamix.docker.manager/include/Helpers.php file

 

 

274   // Add HOST_HOSTNAME variable
275   $Variables[]   = 'HOST_HOSTNAME=$HOSTNAME';
276   // Add HOST_CONTAINERNAME variable
277   $Variables[]   = 'HOST_CONTAINERNAME='.escapeshellarg($xml['Name']);

 

 

All seems to work fine

 

Why would I want this, i hear you cry?

 

Well, in my "Firefox" container the tab name being "Guacamole Client" gave me the poops (being polite!) - so I stuck the following in appdata/firefox/custom-cont-init.d/00.set.guac.page.title.sh

 

filename="/gclient/rdp.ejs"
echo 
echo ----------------------------------------------------------------------------------
echo 
echo "Set the Guacamole Client page title in \"${filename}\""
echo 
echo "Before"
echo "------"
grep "<title>" $filename
sed -i "s+<title>Guacamole Client</title>+<title>${HOST_OS} ${HOST_HOSTNAME} ${HOST_CONTAINERNAME}</title>+g" $filename
echo 
echo "After"
echo "-----"
grep "<title>" $filename
echo 
echo ----------------------------------------------------------------------------------
echo 

 

 

so now my tab is titled "Unraid skynet firefox" - much more OCD friendly....
