The followin HowTo shows how services are used in swarmlab.io!


== What is swarmlab.io?

A Lab management and orchestration tool that provides On Demand Lab Instances.

Lab Instances are services that run your project in a particular programming enviroment. 

The swarmlab.io consists of a main **Git Service** and a **Web-based interactive Lab environment.** 

=== Git service. 

**git.swarmlab.io is a painless self-hosted Git service. **

It is similar to GitHub, Bitbucket, and GitLab. 

https://git.swarmlab.io:3000 - uses **Gitea**.

=== Web-based interactive Lab environment

https://api-client.swarmlab.io:8088 - **api-client.swarmlab.io is a web-based interactive development environment for On Demand Lab Instances**



=== Purpose

The goal of this project is to provide the easiest, fastest, and most painless way of using a LAB and its services and technologies.

==== Repo Directory_Structure_4_Lab_Instance Service

Lab_Instance service first clone your Repo and then automatically loads certain files based on a known file
structure.


.Directory_Structure
[source,bash]
----
swarmlab/
├── Makefile
├── ..
└── ..
----

You need a file called a **Makefile** to tell make what to do. 
The makefile tells make how to compile and link a program,  it can also tell make how to run miscellaneous commands when explicitly asked (for example, to remove certain files as a clean-up operation)

**Makefile** is executed with the make command, e.g. 

.make all
[source,bash]
----
if [ -d swarmlab ]; then
  cd swarmlab
  make all
fi
----


===== Makefile

Lab_Instance dependencies. **"Makefile"** allows you to automatically pull-in other dependencies when using a Lab_Instance service. 

This file should contain a list of tasks and parameters to insert before the specified repos are executed on Lab_Instance and a list of tasks to be executed by the Lab_Instance service.

.Directory_Structure
[source,bash]
----
all: hello_world generate clean

hello_world:
        @echo "Hello World"

generate:
        @echo "Creating empty text files..."
        touch file-{1..10}.txt

clean:
        @echo "Cleaning up..."
        rm *.txt
