Hello, I’m receiving an email, about my server that has a docker image of redis installed and uses port 6379, saying that it is open to external connections.
Redis listens for traffic from everywhere on port 6379, and you can validate this report by attempting to connect to your Redis on 6379 via a simple telnet command:
telnet 220.127.116.11 6379
This is a part of the email, (I masked the IP to put the message here on the forum) I also did the test to see if the port is really open to external connections on the website, https://www.yougetsignal.com /tools/open-ports/ , and it actually shows that my server’s ip port 6379 is open. And the email says to do the following
Remediation of this issue will take just a few minutes and is relatively straightforward. You will need to open /etc/redis/redis.conf and uncomment (remove the “#”) or modify the line beginning with:
#bind 127.0.0.1 ::1
Afterwards, restart redis with:
sudo systemctl restart redis
I would like to know if someone can help me, since I can’t access the redis.config file inside the server, because redis is in a docker image, or at least I don’t know how to access it. Is there any way to block external access to my redis installed by a docker image?
