What do Etcd, Consul, and Zookeeper do?

Service Registration:
- Host, port number, and sometimes authentication credentials, protocols, versions numbers, and/or environment details.
Service Discovery:
- Ability for client application to query the central registry to learn of service location.
Consistent and durable general-purpose K/V store across distributed system.
- Some solutions support this better than others.
- Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
Centralized locking can be based on this K/V store.

Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

Using a Local Registry with Minikube

Install a local Registry

These instructions include running a local registry accessible from Kubernetes as well as from the host development machine at registry.dev.svc.cluster.local:5000.

Use the docker CLI to run the registry:2 container from Docker, listening on port 5000, and persisting images in the ~/.registry/storage directory.

vpngate.py

This script allows to use the free VPN service provided by VPNGate in an easy way. The user just needs to provide the desidered output country, and the script automatically chooses the best server.

After this step, OpenVPN is launched with the proper configuration. The VPN can be terminated by pressing Ctrl+C.

Usage

Run the script by providing the desired output country:
