I am running an Ubuntu box and a simple docker images gives me the following: Error response from daemon: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Notification: DNS Failure</title> <style type="text/css"> body { font-family: ..
I currently run my dns server for my network in a docker container, with port 53 exposed, and it works great, but its created a problem for other containers on the same machine. Other containers can’t access the dns server unless they’re on the same network (this appears to be by design, since the host’s ..

I’m busy moving a Bind9 Server into a Docker Container. The Docker Container is set up to run Debian 10 and Bind9, the setup for Bind9 is a copy of a working Bind9 Server (also on Debian 10). The setup is as follows Debian Docker Host (192.168.20.28) Debian Docker Container (10.1.2.22) ns1.deb10cont.lan ns2.deb10cont.lan host.deb10cont.lan SSH ..
I have image that i’d like to automatically give an address of container that has :5432 opened. Ideas like assigning static IP to that container (or DNS) are not suitable, because I want container to find it out on its own and scripts must work even if previously launched container didn’t have IP or DNS ..
Summary: I want to make NGINX (not NGINX Plus) re-resolve the IP address from the DNS name by using a variable in proxy_pass (as suggested in this official Nginx article in the section "Setting the Domain Name in a Variable"). But when I do that it won’t set/forward the correct Content-Type header, but always use ..
I installed Docker on a CentOS 7 machine and DNS is not working within containers. So, if I run nslookup google.com on my host, it resolves correctly. However, if I do docker container run busybox nslookup google.com I get: Server: 8.8.8.8 Address: 8.8.8.8:53 Non-authoritative answer: Name: google.com Address: 142.250.72.46 *** Can’t find google.com: No answer ..
I’m attempting to learn more about, and set up Envoy (using a Docker image) as a reverse proxy. Requests → Docker container running Envoy → Proxy to a different server based on the request. I’m running into what seems to be an issue resolving the proxy addresses. Here’s what I see when I access localhost:8080. ..
