Docker default Overlay Network
Esta se inicializa automaincamente cuando se une al swarm. no es la mejor recomendación para ambientes productivos.
Necesitamos tres máquinas virtuales corriendo para nuestro lab. En este caso solo las iniciamos.

Podemos ver que ya están en un swarm, ya que previamente se había hecho en la sw-master.

Observamos que en cada máquina virtual tenemos una red ingress y docker_gwbridge.

Observamos que los contenedores workers estan en la red que creamos para master, aún cuando no lo atachamos a los workers.
Creamos una nueva red llamada nginx-net-2 y actualizamos nuestro servicio my-nginx hacia esta red. Esperamos que los contenedores se desconecten de la red donde estaban nginx-net.
bext@bext-VPCF13WFX:~$ docker-machine ssh sw-master "docker network create -d overlay nginx-net-2" 4fsin50c2xxfydo1mfaa638rr bext@bext-VPCF13WFX:~$ eval $(docker-machine env sw-master) bext@bext-VPCF13WFX:~$ docker service update \ > --network-add nginx-net-2 \ > --network-rm nginx-net \ > my-nginx my-nginx overall progress: 5 out of 5 tasks 1/5: running 2/5: running 3/5: running 4/5: running 5/5: running verify: Service converged
Inspeccionamos la red nginx-net la cual desatachamos del servicio.
bext@bext-VPCF13WFX:~$ docker network inspect nginx-net [ { "Name": "nginx-net", "Id": "boynjdp1eb95entflnjdzpg6q", "Created": "2019-07-11T22:40:26.206767548Z", "Scope": "swarm", "Driver": "overlay", "EnableIPv6": false, "IPAM": { "Driver": "default", "Options": null, "Config": [ { "Subnet": "10.0.0.0/24", "Gateway": "10.0.0.1" } ] }, "Internal": false, "Attachable": false, "Ingress": false, "ConfigFrom": { "Network": "" }, "ConfigOnly": false, "Containers": null, "Options": { "com.docker.network.driver.overlay.vxlanid_list": "4097" }, "Labels": null } ]
Vemos que ya no tiene contenedores.
Indagamos las VM
