docker

API for registry

GET /v2/_catalog GET /v2/(name)/manifests/(tag) GET /v2/(name)/tags/list

API for docker daemon

GET /info GET /version GET /networks GET /volumes GET /events GET /images/json GET /images/(name)/json GET /containers/json GET /containers/(id)/stats GET /containers/(name)/json

Architecture for docker

*) consul/etcd + dnsmasq for service discovery *) ldap for auth service *) docker daemon *) auth for all docker daemons *) swarm agent for all docker daemons

network

a. bridge network(single-host)

docker network ls
docker network inspect bridge
docker network inspect isolated_nw
docker network create --driver bridge isolated_nw
docker run --net=<NETWORK> -d -it image 

b. overlay network(multi-host) This support is accomplished with the help of libnetwork, a built-in VXLAN-based overlay network driver, and Docker’s libkv library. Currently, Docker’s libkv supports Consul, Etcd, and ZooKeeper.
