Docker network modes and docker network Modes When using docker run to create a Docker container, you can use the -- net option to specify the container network mode. Docker has the following four network modes: · Host mode, specified using -- net = host. · Container mode, w

First set of ip:192.168.12.3 Second set of ip:192.168.12.4 Demo with a second server with Docker installed. To differentiate, set the label differently. To modify the daemon (Server) default startup configuration: The default is:-H fd://, can be modified to:-H tcp://0.0.0.0:2375-h unix:///var/run/

is that when you run a specific mirror, you can specify your container DNS server.When you have a consul run (or other DNS server) you can add it to your Docker daemon just like this: Docker run-d--dns $IP _consul--dns-search service.consul dockerrun-d--dns $IP _consul--dns-searchservice.consul Now we can solve the IP address of all containers registered with Consul name, for example in our environmen

virtualization tools, such as VPS that have long been heard of?From a technical point of view, the underlying principle is similar. Look at the picture. Docker, like other OS virtualization technologies, has roughly the same technical implementation. The key to see who can drive the ecosystem, to win the support of other manufacturers. At the same time, Docker's layered file system implementation is also a particularly fascinating place. Here is the
