Command TestsThere are four types of tests we can perform on a container image with this framework;. These tests allow us to execute a given command inside the container image and verify if the output matches what is expected, or is an error.

A good example of a command test is to verify the installation of packages or binaries in the container image. File existence tests are used to check for the existence of expected files in a container image.

We often create working directories in our container images and even move around files to this directory. We can check if the files exist in the working directory with the File existence tests. This test checks to ensure that given container metadata is accurate.

Small container images give us better performance and security for applications. To ensure reliable containers in production, unit test the container images to validate their structure using the container structure test framework from Google.

RUN apk -- update add -- virtual build - dependencies ruby - dev build - base. It's like a Ruby implementation of a CGI which offers a standard protocol for web servers to execute programs. Rack's run here means for requests to the server, make Sinatra::Application the execution context from which Sinatra's DSL could be used. All DSL methods on the main are then delegated to this class. The get block would mean something to Rack, in this case when someone tries to access [GET] the home url,.

The interface just assumes that you have an object that responds to a call method like a proc and returns a array with:. You can run a basic Rack server with the rackup command which will search for a config. Since Sinatra just like Rails builds on Rack it uses rackup internally to interface between the server and the framework. What it does is bootstrap the application and pass the Sinatra::Application class to rack which has a call class method.

Sinatra::Application is then responsible for taking the incoming request the env and passing it to the routes your application provides and then passing back the response code, headers, and response body.

Rack is an interface and architecture that provides a domain specific language DSL and connects an application with a world of web. In two words, it allows to build web applications and work with requests, responses and many other web-related technologies in a most convenient way.

You will need to configure your development environment with the prerequisites in order to develop an application using the Ruby Driver for SQL Server. No additional configuration is required.

Download Ruby Installer If your machine does not have Ruby, install it. For new ruby users, we recommend you use Ruby 2.
