Unable to start installation within a docker

[Bill F]

I am trying to develop docker version of ResourceSpace for our workplace NAS server.

The setup page loads fine and we are able to input all the information on the setup page but when we click "Begin Installation" button, the browser would work in background for a few seconds then take us to a blank page.  

Two errors we can find are .. 

in httpd error log:

PHP Fatal error:  Uncaught mysqli_sql_exception: php_network_getaddresses: getaddrinfo for backend failed: Temporary failure in name resolution in /var/www/html/pages/setup.php:544\nStack trace:\n#0 /var/www/html/pages/setup.php(544): mysqli_connect()\n#1 {main}\n  thrown in /var/www/html/pages/setup.php on line 544, referer: http://localhost:4000/pages/setup.php

And in browser console log:

GET http://localhost:4000/lib/fontawesome/css/font-awesome.min.css net::ERR_ABORTED 404 (Not Found)

jquery-3.6.0.min.js:2          GET http://localhost:4000/pages/dbtest.php?mysqlserver=backend&mysqlusername=resourcespaceuser&mysqlpassword=&mysqldb=resourcespacedb 500 (Internal Server Error)

What am I doing wrong or missing?

Thank you

Bill,

I am having the same issue. Have redeployed container multiple times and adjusted .env file and double check i have things correct but still cannot get mine to install. Just get the blank page. I know this is a very old post but if you figured it out let me know.
