I am pretty new to Django. I think I cannot run django application as sudo since all pip related modules are installed for the user and not for the sudo user. So, it's a kind of basic question like how do I run django app that can listen for port 80 as well as port 443.
So, far I have tried following option - i.e pre-routing - NAT
I run my app using the following command -
$python manage.py runserver Performing system checks... System check identified no issues (0 silenced). You have 15 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions. Run 'python manage.py migrate' to apply them.

Next, here is my iptables settings nothing worked for me though
$sudo iptables -t nat --line-numbers -n -L Chain PREROUTING (policy ACCEPT) num target prot opt source destination 1 DOCKER all -- 0.0.0.0/0 0.0.0.0/0 ADDRTYPE match dst-type LOCAL 2 REDIRECT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 redir ports 8000 Chain INPUT (policy ACCEPT) num target prot opt source destination Chain OUTPUT (policy ACCEPT) num target prot opt source destination 1 DOCKER all -- 0.0.0.0/0 !127.0.0.0/8 ADDRTYPE match dst-type LOCAL Chain POSTROUTING (policy ACCEPT) num target prot opt source destination 1 MASQUERADE all -- 172.17.0.0/16 0.0.0.0/0 2 RETURN all -- 192.168.122.0/24 22.214.171.124/24 3 RETURN all -- 192.168.122.0/24 255.255.255.255 4 MASQUERADE tcp -- 192.168.122.0/24 !192.168.122.0/24 masq ports: 1024-65535 5 MASQUERADE udp -- 192.168.122.0/24 !192.168.122.0/24 masq ports: 1024-65535 6 MASQUERADE all -- 192.168.122.0/24 !192.168.122.0/24 Chain DOCKER (2 references) num target prot opt source destination 1 RETURN all -- 0.0.0.0/0 0.0.0.0/0
I did http:// and I see connection refused. I have no idea how to debug the NAT stuff whether it is actually hitting NAT or not. How can I debug and also what is the correct solution to it?
