This gist demonstrates how to test the availability of a TCP endponit using Golang. The following example checks if an endpoint is available and responding to both TCP and TLS connections. To run the example, simply open a command line and execute the following:

$ curl -sSL https://goo.gl/ENx9d8 > tcp-tls-ping.go && go run tcp-tls-ping.go
tcp success
tls success

The program shows that the specified endpoint (defaults to google.com:443) is available and responding to TCP and TLS connection attempts. To illustrate the error that occurs when an endpoint presents an invalid TLS certificate, execute the following:

REX-Ray's Build Command

The new build.sh command (PR #864) simplifies building REX-Ray from source. The command supports two types of build platforms: make and Docker.

Build with `make`

The make command is the traditional tool used to build software. To build REX-Ray with make using the build.sh command, simply use the -b flag to specify the make builder:

$ ./build.sh -b make

REX-Ray/CSI Architecture Review

REX-Ray and the Container Storage Interface (CSI) support three architectural models: centralized, decentralized-split, and decentralized-unified. This document identifies the components of each architecture and their relationship to the three, common component types: client, agent, and controller.

REX-Ray+CSI

The introduction of the Container Storage Interface (CSI) provides an exciting opportunity to the world of Container Orchestrator (CO) and storage. This document reviews how CSI adds value to REX-Ray, strengthening its position as the leading CO storage management solution.

Note: Before reading this document please take time to review the several REX-Ray/CSI architecture and component types.
