Docker iptables allow portRequests from the IP range Docker uses are likely getting blocked. It's a private IP address range, so there's minimal risk in having it open. For UFW, that would be: sudo ufw allow from 172.18../24. Optionally specifying a port to open: sudo ufw allow from 172.18../24 to any port 9200. For iptables, that would be: iptables --append ...The picture below is docker The rules.

To allow only a specific IP or network to access the containers, insert a negated rule at the top of the DOCKER filter chain. For example, to restrict external access such that only source IP 8.8.8.8 can access the containers, the following rule could be added: $ iptables -I DOCKER -i ext_if ! -s 8.8.8.8 -j DROP.Internally Docker is using iptables to forward connections to the docker host on port 8080 to the service listening on port 80 on the container. The key in your configuration is this line - -A DOCKER ! -i docker0 -p tcp -m tcp --dport 8080 -j DNAT --to-destination 172.17..2:80Next, we locate the program that we want to allow through the firewall in the outbound direction.

For instance, if you have the following docker-compose file: version: '3' services: app: image: kennethreitz/httpbin ports: - "80:80" # httpbin server listens on the container's 0.0.0.0:80. And you want to scale up the app service with docker-compose up ... docker exec app1 apt install iptables -y. Verify it works: docker exec app1 iptables -S. It should output:-P INPUT ACCEPT-P FORWARD ACCEPT-P OUTPUT ACCEPT Step 3. Block All Traffic. First, we block all traffic to the port that is bound in the container. Here, it is port 80, not 8080. docker exec app1 iptables -A INPUT -p tcp --dport 80 -j DROPThe correct way is to put it at the very end of the rule chain, after the rules created by docker. So if you have the same problem, this works for me: Get rid of the rule. $ sudo iptables -D FORWARD -j REJECT. Add it again to move it to the end of the set. $ sudo iptables -A FORWARD -j REJECT. Make sure they are in the right order.In this case the host allows the connection because the FORWARD chain has iifname "docker0" oifname "docker0" accept. On the flip-side, if container A tries to connect to the forwarded port on the host then it does enter the host's INPUT chain and with the above rules it gets blocked.

Therefore I use the following iptables entry for the ip of my external interface (ext_if): iptables -I DOCKER-USER -i eth0 ! -s ext_if -j DROPOn Linux, Docker creates a set of Netfilter chains to manage its Docker Network. When a port is exposed from a container, the related chains are munged to allow the port access. By default, this maps the port to the IPv4 address 0.0.0.0 and effectively does two things: Exposes the port through the firewall to the outside world.To make a port available to services outside of Docker, or to Docker containers which are not connected to the container's network, use the --publish or -p flag. This creates a firewall rule which maps a container port to a port on the Docker host to the outside world. Here are some examples. IP address and hostname 🔗sudo iptables -A INPUT -i lo -j ACCEPT sudo iptables -A OUTPUT -o lo -j ACCEPT sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT.

This creates a firewall rule which maps a container port to a port on the Docker host to the outside world. Here are some examples. IP address and hostname 🔗The most popular solution to the docker + ufw problem is to configure the docker daemon with --iptables=false. This is a bad idea because it makes docker unusable by blocking out-bound traffic as well as any networking between containers. So if you want docker to function properly, you will need to create and manage iptables rules manually.With UFW, you can also allow or block ports using the port number. For example, to allow the TCP port 8080 using UFW, run the following command: $ sudo ufw allow 8080/ tcp. The required firewall rules for allowing the TCP port 8080 should be added. As you can see, the TCP port 8080 is allowed.ufw default deny incoming ufw allow OpenSSH ufw allow http ufw allow https ufw enable But Docker will update iptables when you bind a container port to the host, opening the port for public access. To prevent this, you could bind the port to an internal address (private or 127.0.0.1).在 Docker host 主機上用 UFW 設定防火牆規則時,會發生 Docker container expose 到 Docker host 上的 port 不被 UFW 設定的規則阻擋。 例如:在 UFW 中設定的規則為 123456789# ufw status verboseStatus: activeDefault: deny (incoming), allow (outgoing)Jan 08, 2022 · Currently Podman/Docker support the use of macvlan to build a container network, this mode to create containers directly connected to the external network, containers can have independent external IP, no port mapping, and do not need to use iptables.
