I saw a lot of similar problem but not exactly like mine... I have a classic architecture,
A server with docker, a stack with Traefik to dispatch request, and few stack of nginx/apache and php. Let's say
- website1.com
- website2.com
The problem is that I can't cURL another website from inside a docker container.
If I try to curl from server itself
curl -v website2.com
curl -v https://website2.com
I get a valid response
If I try to curl from website1 container
curl -v website2.com
curl -v https://website2.com
I can see
Trying XX.XX.XX.XX:443...
With my external IP (so the DNS should be OK) but I don't get any response so it end with a timeout message.
If I add 192.168.48.4 website2.com into my /etc/hosts and I try to cURL, I get a valid response but tell me if I'm wrong but in this case it access through local and not from outside of the server
By the way, I need to cURL from a "manager" website that get all domains from an API, so cURL should be dynamic and I can't really add all IP manually into a hosts file or whatever
I really want to access other containers from outside, like an external service
Do you have any suggestion ? Thank you guys

Thanks for comment and specifically to this topic https://community.traefik.io/t/curl-from-container-a-to-b-blocked/1040/14
In my case, the firewall (ufw) of my host was "blocking" my http/https requests, even if my domains were accessible
Thoses commands fix my problem
sudo ufw allow http
sudo ufw allow https
