httpd-docker's Issues

docker-apt-install fails due to /etc/os-release changes.

The current implementation of docker-apt-install retrieves the code name from /etc/os-release as follows:

codename=$(cat /etc/os-release | grep CODENAME | awk -F= '{print $2}')

The new docker image was changed to include the UBUNTU_CODENAME property as well:

$ cat /etc/os-release NAME="Ubuntu" VERSION="16.04.1 LTS (Xenial Xerus)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 16.04.1 LTS" VERSION_ID="16.04" HOME_URL="http://www.ubuntu.com/" SUPPORT_URL="http://help.ubuntu.com/" BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/" VERSION_CODENAME=xenial UBUNTU_CODENAME=xenial

As both the VERSION_CODENAME and UBUNTU_CODENAME lines are matched, xenial\nxenial is injected into /etc/apt/sources.list causing a failure.

Change the value of AuthnCacheContext?

Thanks for providing the container! I have a question about one httpd config:AuthnCacheContext.
It seems the official document recommends to change the default directory, which is conservative and not optimal. A better policy is to name the AuthnCacheContext for the password provider: for example a htpasswd file or database table.

Maybe it's better to set that to specify a context string for use in the cache keyin the comfig file? Thanks.
