How to access lxc container from outside?

LXC containers are by default isolated from the outside network, but they can be configured to connect to the internet or be accessible from outside the host system.

To gain access to an LXC container from the outside, we must first:

1. Examine the LXC container’s IP address:

   a:To obtain the IP address of the container, we may use the “ip addr” command.

   b: Instead, we may use the “lxc-info” command on the host system to obtain the container’s IP address.
2. Set up port forwarding on the host machine as follows:

   a:We must forward the port from the host system to the IP address and port of the container.

   b: On the host system, we may configure port forwarding using the “iptables” command.

   The following command, for example, forwards port 80 on the host system to port 80 on the container with IP address 192.168.1.100:

   sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.1.100:80
3. To check the connection, do the following:

   a: To test the connection, we may use a web browser or any other program that can connect to the forwarded port.

   b: To visit the web server operating within the container, open a web browser on the host machine and type “http://localhost” into the address bar.

It is important to note that port forwarding might constitute a security concern since it exposes the container to the outside network.

We should only use port forwarding when we need to access a service operating within the container from somewhere other than the host system, and we should always setup it properly to avoid unwanted access.
