– Crear un volumen

docker volume create portainer_data
docker volume ls

– Crear el servicio, para tener acceso a los managers

docker service create --name portainer -p 9000:9000 --constraint node.role==manager --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock --mount type=volume,src=portainer_data,dst=/data portainer/portainer -H unix:///var/run/docker.sock

Muy buena herramienta

docker volume create portainer_data
docker volume ls
docker service create --name portainer -p 9000:9000 --constraint node.role==manager --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock --mount type=volume,src=portainer_data,dst=/data portainer/portainer -H unix:///var/run/docker.sock
docker stack ls
docker stack ps voting
docker service ps voting_worker

Portainer
Voting

https://docs.docker.com/engine/extend/plugins_services/

El curso está genial de verdad!

For the greater good, here we go!

docker service create --name portainer -p 9000:9000 --constraint node.role==manager
–mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock
–mount type=volume,src=portainer_data,dst=/data portainer/portainer
-H unix:///var/run/docker.sock

• Las herramientas de administración en Docker Swarm deben persistir en disco (su estado interno, la administración) y la mejor manera de almacenar cosas en Docker son los volúmenes.
• Plugins para storage compartido REX-ray, Glusterfs, docker swarn volume

Esto es demasiado poderoso. #DockerFan.

Qué buena clase. 😄

docker service create --name portainer -p 9000:9000 --constraint node.role==manager --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock --mount type=volume,src=portainer_data,dst=/data portainer/portainer -H unix:///var/run/docker.sock

Comando para levantar un servicio de Portainer

Muy buena clase!!!
