Managing Files on LXD Containers

LXD offers a command-line interface for efficiently managing files on our Linux containers. We can both push and pull files to and from our containers, or leverage the `edit` command to edit files without ever having to log in to the container directly. In this lab, we'll be using all of these commands to configure Apache on an Ubuntu Linux host.

Create the containerhub Configuration

Copy an existing profile:

lxc file pull web01/etc/apache2/sites-available/000-default.conf containerhub.conf

Update the containerhub.conf file:

vim containerhub.conf

<VirtualHost *:80>
 ServerName www.containerhub.example

 ServerAdmin hub@localhost
 DocumentRoot /var/www/html

 ErrorLog ${APACHE_LOG_DIR}/error.log
 CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

Push the file to the container:

lxc file push containerhub.conf web01/etc/apache2/sites-available/containerhub.conf

Confirm the file was added:

lxc file edit web01/etc/apache2/sites-available/containerhub.conf

Challenge

Enable the New Configuration

Remove the old 000-default.conf configuration from the sites-enabled directory:
```
lxc file delete web01/etc/apache2/sites-enabled/000-default.conf
```

Enable the new configuration:

lxc exec web01 -- a2ensite containerhub
lxc exec web01 -- systemctl reload apache2

Challenge

Test the New Configuration
1. Update the index.html file to say a simple sentence:
  
  lxc file edit web01/var/www/html/index.html
  
  Website test
2. Retrieve the private IP address of the container:
  
  lxc list
3. Curl the website:
  
  curl <web01_private_ip>
