Hence, weird workarounds like usingĮxtrahosts or double name policies can be avoided.įor routing management at the overlay level. maintains a lightweight host system and uses Docker containers for all applications.
On many occasions, deployments running on multiple docker daemons do not enter into designing their networking approach, but they can have great benefits by using overlays for a number of reasons:Īmong different hosts can be easily encrypted. When using docksal with Docker for Mac, it seems that (documented here. This ping packet is travelling across the two CoreOS nodes and is.
Macvlan networks are best when you are migrating from a VM setup or need yourĬontainers to look like physical hosts on your network, each with a unique MAC Create two containers: docker run -d -name web1-p 8001:80 eboraas/apache-php docker run -d -name web2-p 8002:80 eboraas/apache-php Important note: it is very important to explicitly specify a name with -name for your containers otherwise I’ve noticed that it would not work with the random names that Docker assigns to your containers. Overlay networks are best when you need containers running on different Docker hosts toĬommunicate, or when multiple applications work together using swarm services. Host, but you want other aspects of the container to be isolated. Host networks are best when the network stack should not be isolated from the Docker User-defined bridge networks are best when you need multiple containers to communicate on the same
