1. Challenge

   Create the Container

   Launch an Alpine Linux 3.18 container, called web01:

   lxc launch images:alpine/3.18 web01
   

2. Challenge

   Configure nginx

   Access the container's shell:

   lxc exec web01 -- ash
   

   Update the container and install nginx:

   apk update
   apk add nginx
   

   Configure nginx to start at boot:

   rc-service nginx start && rc-update add nginx default
   

   Update the nginx configuration to serve content out of /var/www/hub at port 80:

   vi /etc/nginx/http.d/default.conf
   

   server {
           listen 80 default_server;
           listen [::]:80 default_server;
   
   
           root /var/www/hub/;
   }
   

   Exit the container:

   exit
   

3. Challenge

   Deploy the Website

   Push the website to the container:

   lxc file push hub/ web01/var/www/ --create-dirs -r
   

   Then restart nginx:

   lxc exec web01 -- rc-service nginx restart
   

   We can confirm this work by running curl against the private IP of our container:

   lxc list
   curl <container-ip-from-list>
   

4. Challenge

   Snapshot the Container

   Take a snapshot of the web01 container:

   lxc snapshot web01 1.0
   

5. Challenge

   Map Ports

   Ensure that when the host's IP is accessed, it forwards to the container:

   sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to <container_ip>:80
   

   To confirm visit the public IP of your provided server.
