Custom listening port 80 443

[chryuvski]

The container must run in host mode to make it easier to map new ports in Streams without restarting the container.
And since in China ports 443 and 80 are all blocked to personal server, I hope I can change the default port 80, 443

Hi @chryuvski. Hope you're doing well.

The need to run in host network mode or restart the container is, unfortunately, a limitation of how Docker works. As an alternative, you can install and run Ignition directly on the host.

Regarding the default ports, you can change them in two ways:

• Globally by using the Settings page. Under the Nginx tab, you will find the list of "Global Bindings" (the default ports) at the bottom of the page.
• Per Host by toggling the "Use global bindings" option in the bindings section of the specific host's page. Once disabled, you'll be able to use specific ports that apply only to the specific host.

Oh thanks for your response. But I dont wanna install in on the host for now. Sorry that I havent noticed the Global Bindings before. And now I change http port to 380, then I change docker-compose.yml to 'network_mode: "host"'. Ideally, I should be able to access my web successfully using the port 380, but it doesn't, even though theoretically it should work.

The way I see it, there could be a few different reasons why it is still not working. Because of that, I can't say for sure what is happening, but I can suggest a strategy to help isolate and pinpoint the issue.

Start inside the container and perform a wget, curl, or similar command to localhost:380. If it works, try doing the same from the host, then from another machine on your local network, and finally through the internet (if it is exposed publicly).

The point at which it stops working is where you should focus your investigation. For example, if it works on the host but not on another machine, it could be a firewall on the host blocking the request.

Another possibility worth checking is the privileges required to bind to port 380. By default, the Linux kernel restricts privileged ports (1024 and lower) to the root user. One place to check this is the "Runtime user" on the Ignition Settings page.

Hope this helps.

hmmm. I can access it inside the container and from the host.
Let me make myself clear. First of all, I use bridge mode to map 380:80 and 3443:443, and i can access my website using http://my.domain:380. Then I change the mode to 'host' and I can't access it anymore. And I've change the port to 3380, it still doesn't work.
I used the command sudo netstat -tulpn | grep :3380 . It shows the port 3380 is being listened by the nginx-ingition.
I'm not familiar with these and sorry if i bother you. Maybe I'll let it stay in bridge mode as common

Hi, @chryuvski.

When you switch to host mode, port binding settings isn't used anymore by Docker. The port that you set on nginx is the one opened in the host.

Since you're using 380 in nginx, you should be able to access from another machine in your local network using port 380 as well.

[chryuvski]

Yeah, I'm using nginx proxy manager host mode right now. I've changed the listening port by modify the inner config file just like this and it works fun. So I think it works for this project as well
