On Oracle Cloud, you need to add ports to Security List.
Once you add it this way, the port will be opened,
The problem now is that the port isn’t open on Ubuntu.
As you can see by checking iptables -nvL here, external access isn’t enabled,
I was told that to solve this problem, I needed to add the port using an iptables command. I tried adding it with an iptables command, saving the configuration, and rebooting, but... it still didn’t work... (couldn’t connect to Docker)
So instead of configuring iptables, I installed and configured ufw, which solved the problem.
apt install ufw
ufw allow 22
ufw allow 80
ufw enableufw status
Status: active
To Action From
-- ------ ----
22 ALLOW Anywhere
80 ALLOW Anywhere
22 (v6) ALLOW Anywhere (v6)
80 (v6) ALLOW Anywhere (v6)With this, port 80 will open properly, and you’ll be able to connect to Docker (the traefik/whoami containers).
※ Be sure!!! You must register port 22! Otherwise, SSH access to port 22 from outside will be impossible.
For reference, after adding ports with ufw, you need to reboot once.
