Advanced Settings > Network > Use the same network as Docker Host The setting **Use the same network as Docker Host** is important. This allows Asterisk to open ports and communicate without restriction. Ideally it would not be required but Synology's Docker web interface is limited. The req...
By reading the documentation I have understood that docker-compose provides a mechanism to bind different containers together and work in collaboration, as a single service (I'm guessing it's using the same functionality as --link command used to link two containers) Also, my understanding of d...
I myself did not have success with networks or network_mode, but if you want to access a network service on the host, you can simply have the host service listen on the docker0 network interface, which is accessible from the container (depending on your network mode) at the same ip add...
these two images are in two containers but they are in same network My host system is windows machine one of my docker container is of debian based 5 . I have written docker-compose file to run my both containers for building i use docker-compose build and run i use docker-compose...
Next, let's take a look at how to quickly use this "mail tool" through the container. Use Docker to quickly experience the mail gateway If we want to start a "mail gateway", we can directly use the "one sentence" container command to solve the battle: ...
Ao não especificar uma porta de host no mapeamento de portas, é possível fazer com que o Docker escolha uma porta aleatória e não usada do intervalo de portas temporárias e a atribua como porta de host pública para o contêiner. Por exemplo, a aplicação Node.js rece...
Docker containers provide security features to run multiple containers simultaneously on the same host without affecting each other. As we saw, we can configure both data storage and network configuration to isolate our containers or share data and connectivity between specific containers. ...
Hi, actually I want to deploy all my applications in one machine and I use "network_mode: host" for sharing the same network of host machine inside docker container. But I find that I can't access my application with "localhost" in the h...
To solve this problem, consider using the bridge network mode with a dynamic port mapping as shown in the following diagram.By not specifying a host port in the port mapping, you can have Docker choose a random, unused port from the ephemeral port range and assign it as the public host ...
Summary In networks where external DNS servers are blocked, Docker containers running on Ubuntu hosts can't resolve DNS at all because they are trying to use 8.8.8.8 as their DNS server. Docker should detect the network DNS server. Detai...
