3. Docker Swarm

4. Docker Swarm
Cluster de forma nativa
Discovery mediante TOKEN
Master y Nodes
Desarrollado en Go

5. Docker Swarm
Demo con
Docker Machine y driver
VirtualBox

6. Docker Swarm
Crear token: $ docker run swarm create
Crear nodo master:
docker-machine create
-d virtualbox
--swarm
--swarm-master
--swarm-discovery token://<TOKEN>
swarm-master

7. Docker Swarm
Crear nodo agent-00:
$ docker-machine create
-d virtualbox
--swarm
--swarm-discovery token://<TOKEN>
swarm-node-00

8. Docker Swarm
Crear nodo agent-00:
$ docker-machine create
-d virtualbox
--swarm
--swarm-discovery token://<TOKEN>
swarm-node-01

9. Docker Swarm
Conectarse a cada nodo:
$ eval "$(docker-machine env swarm-node-00)"
$ eval "$(docker-machine env swarm-node-01)"
Conectarse al master:
$ eval "$(docker-machine env --swarm swarm-
master)"

10. Docker Swarm
Lanzar en cada nodo:
$ watch docker ps -a
En el master:
$ docker info
$ docker run alpine echo 'hello swarm 1'
$ docker run alpine echo 'hello swarm 2'
$ docker run alpine echo 'hello swarm 3'
