/ HOWTO

Monitorizando Docker Server.

Utilizaremos un proyecto GIT “all in one”, que genera varios contenedores que trabajan juntos para darnos una interfaz gráfica.

Descargamos el proyecto GIT.

# git clone https://github.com/stefanprodan/dockprom
# cd dockprom

Usando “docker-compose” preparamos los contenedores.

# docker-compose up -d

# docker ps
