Apache ServerName configuration is faulty

[raphaelstolt]

I used the 5.0.0 release from a Windows box and noticed that the Apache ServerName configuration contains some sort of hash instead of the default docker.vm value.

Can you provide more informations? Please attach the apache configuration.

The Apache config /opt/docker/etc/httpd/global.conf on the app container looks like the following:

# Settings
TimeOut      1000
ServerName   "f66ccf4ce501"

DirectoryIndex index.php
DocumentRoot "/app/web/"

<Directory "/app/web/">
  Options Indexes FollowSymLinks
  AllowOverride All

  <IfVersion < 2.4>
      Allow from all
  </IfVersion>
  <IfVersion >= 2.4>
      Require all granted
  </IfVersion>
</Directory>

LogFormat "[httpd:access] %V:%p %h %l %u %t \"%r\" %>s bytesIn:%I bytesOut:%O reqTime:%T" dockerlog
CustomLog /proc/self/fd/1 dockerlog
ErrorLog  /proc/self/fd/2

From the Docker log it also seems that the ServerName value is not set correctly, would expect to see the value configured in application.development.yml there.

changed: [localhost] => (item=[{u'variable': u'SERVERNAME', u'value': u'f66ccf4ce501'}, u'/opt/docker/etc/httpd/global.conf'])
ok: [localhost] => (item=[{u'variable': u'SERVERNAME', u'value': u'f66ccf4ce501'}, u'/opt/docker/etc/httpd/main.conf'])
ok: [localhost] => (item=[{u'variable': u'SERVERNAME', u'value': u'f66ccf4ce501'}, u'/opt/docker/etc/httpd/php.conf'])
ok: [localhost] => (item=[{u'variable': u'SERVERNAME', u'value': u'f66ccf4ce501'}, u'/opt/docker/etc/httpd/vhost.common.conf'])
ok: [localhost] => (item=[{u'variable': u'SERVERNAME', u'value': u'f66ccf4ce501'}, u'/opt/docker/etc/httpd/vhost.conf'])
ok: [localhost] => (item=[{u'variable': u'SERVERNAME', u'value': u'f66ccf4ce501'}, u'/opt/docker/etc/httpd/vhost.ssl.conf'])

Though just noticed that in /opt/docker/etc/httpd/vhost.conf the value is correctly expanded.

So why is this closed w/o comment?

This issue is not fixed? I thought that this issue is fixed.

The Apache ServerName is the global host name of the Apache server and will be set to the hostname of the current docker Container.

There are vhosts with your which uses the *.vm domains which also overwrite the ServerName inside.

[mblaschke]

There is now a modular apache configuration available by using /opt/docker/etc/httpd/conf.d for global configuration and /opt/docker/etc/httpd/vhost.common.d for vhost configuration.
