Two weeks ago, I gave a presentation at the 42nd Docker Paris Meetup about Rancher. Rancher is a Docker orchestrator and, as such, a competitor of Docker Swarm and Kubernetes. However, it has some other features that make it very interesting and not incompatible with Swarm or Kubernetes.
Here is the first part of the presentation:
a general presentation of Rancher, a first demonstration: creating and scaling an Elasticsearch cluster in Rancher.
Classic network topology Typically, in a classical infrastructure, network architects design multiple networks according to the security wanted for the elements residing in the network. For instance, for a web infrastructure, you could have a front network, where the webservers live, which is accessible from the Internet on ports 80 and 443 ; and a back network, for the database servers, which is only accessible from the front network. This is a fine design, because it allows you to manage security between the networks with firewalls and routing restrictions.
