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
