vagga

"Vagga is a tool to create development environments. In particular it is able to:

• Build container and run program with single command, right after “git pull”
• Automatically rebuild container if project dependencies change
• Run multiple processes (e.g. application and database) with single command
• Execute network tolerance tests

All this seamlessly works using linux namespaces (or containers).

Let’s make config for hello-world flask application. To start you need to put following in vagga.yaml:

containers:
  flask: ❶
    setup:
    - !Ubuntu xenial ❷
    - !UbuntuUniverse ❸
    - !Install [python3-flask] ❹
commands:
  py3: !Command ❺
    container: flask ❻
    run: python3 ❼

• ❶ – create a container “flask”
• ❷ – install base image of ubuntu
• ❸ – enable the universe repository in ubuntu
• ❹ – install flask from package (from ubuntu universe)
• ❺ – create a simple command “py3”
• ❻ – run command in container “flask”
• ❼ – the command-line is “python3”

To run command just run vagga command_name."
