This repository contains the initial stage of a student project to build a clone of the AirBnB website. This stage implements a backend interface, or console, to manage program data. Console commands allow the user to create, update, and destroy objects, as well as manage file storage. Using a system of JSON serialization/deserialization, storage is persistent between sessions.

1. First clone this repository.

2. Once the repository is cloned locate the "console.py" file and run it as follows:

/AirBnB_clone$ ./console.py

4. When this command is run the following prompt should appear:

(hbnb)

5. This prompt designates you are in the "HBnB" console. There are a variety of commands available within the console program.

* create - Creates an instance based on given class

* destroy - Destroys an object based on class and UUID

* show - Shows an object based on class and UUID

* all - Shows all objects the program has access to, or all objects of a given class

* update - Updates existing attributes an object based on class name and UUID

* quit - Exits the program (EOF will as well)

Users are able to issue a number of console command using an alternative syntax:

Usage: <class_name>.<command>([<id>[name_arg value_arg]|[kwargs]])

Advanced syntax is implemented for the following commands:

* all - Shows all objects the program has access to, or all objects of a given class

* count - Return number of object instances by class

* show - Shows an object based on class and UUID

* destroy - Destroys an object based on class and UUID

* update - Updates existing attributes an object based on class name and UUID

Usage: create <class_name>

# 0x03. AirBnB clone - Deploy static

• What is Fabric
• How to deploy code to a server easily
• What is a tgz archive
• How to execute Fabric command locally
• How to execute Fabric command remotely
• How to transfer files with Fabric
• How to manage Nginx configuration
• What is the difference between root and alias in a Nginx configuration

• 0-setup_web_static.sh : Write a Bash script that sets up your web servers for the deployment of web_static. It must:
  • Install Nginx if it not already installed
  • Create the folder /data/ if it doesn’t already exist
  • Create the folder /data/web_static/ if it doesn’t already exist
  • Create the folder /data/web_static/releases/ if it doesn’t already exist
  • Create the folder /data/web_static/shared/ if it doesn’t already exist
  • Create the folder /data/web_static/releases/test/ if it doesn’t already exist
  • Create a fake HTML file /data/web_static/releases/test/index.html (with simple content, to test your Nginx configuration)
  • Create a symbolic link /data/web_static/current linked to the /data/web_static/releases/test/ folder. If the symbolic link already exists, it should be deleted and recreated every time the script is ran.
  • Give ownership of the /data/ folder to the ubuntu user AND group (you can assume this user and group exist). This should be recursive; everything inside should be created/owned by this user/group.
  • Update the Nginx configuration to serve the content of /data/web_static/current/ to hbnb_static (ex: https://mydomainname.tech/hbnb_static). Don’t forget to restart Nginx after updating the configuration:
    • Use alias inside your Nginx configuration
  • Your program should always exit successfully. Don’t forget to run your script on both of your web servers.
• 1-pack_web_static.py : Write a Fabric script that generates a .tgz archive from the contents of the web_static folder of your AirBnB Clone repo, using the function do_pack.
  • Prototype: def do_pack():
  • All files in the folder web_static must be added to the final archive
  • All archives must be stored in the folder versions (your function should create this folder if it doesn’t exist)
  • The name of the archive created must be web_static_.tgz
  • The function do_pack must return the archive path if the archive has been correctly generated. Otherwise, it should return None
• 2-do_deploy_web_static.py : Write a Fabric script (based on the file 1-pack_web_static.py) that distributes an archive to your web servers, using the function do_deploy:
  • Prototype: def do_deploy(archive_path):
  • Returns False if the file at the path archive_path doesn’t exist
  • The script should take the following steps:
    • Upload the archive to the /tmp/ directory of the web server
    • Uncompress the archive to the folder /data/web_static/releases/ on the web server
    • Delete the archive from the web server
    • Delete the symbolic link /data/web_static/current from the web server
    • Create a new the symbolic link /data/web_static/current on the web server, linked to the new version of your code (/data/web_static/releases/)
  • All remote commands must be executed on your both web servers (using env.hosts = ['', 'IP web-02'] variable in your script)
  • Returns True if all operations have been done correctly, otherwise returns False
  • You must use this script to deploy it on your servers: xx-web-01 and xx-web-02
  • In the following example, the SSH key and the username used for accessing to the server are passed in the command line. Of course, you could define them as Fabric environment variables (ex: env.user =...)
  • Disclaimer: commands execute by Fabric displayed below are linked to the way we implemented the archive function do_pack - like the mv command - depending of your implementation of it, you may don’t need it
• 3-deploy_web_static.py : Write a Fabric script (based on the file 2-do_deploy_web_static.py) that creates and distributes an archive to your web servers, using the function deploy:
  • Prototype: def deploy():
  • The script should take the following steps:
    • Call the do_pack() function and store the path of the created archive
    • Return False if no archive has been created
    • Call the do_deploy(archive_path) function, using the new path of the new archive
    • Return the return value of do_deploy
  • All remote commands must be executed on both of web your servers (using env.hosts = ['', 'IP web-02'] variable in your script)
  • You must use this script to deploy it on your servers: xx-web-01 and xx-web-02
• 100-clean_web_static.py : Write a Fabric script (based on the file 3-deploy_web_static.py) that deletes out-of-date archives, using the function do_clean:
  • Prototype: def do_clean(number=0):
  • number is the number of the archives, including the most recent, to keep
    • If number is 0 or 1, keep only the most recent version of your archive.
    • if number is 2, keep the most recent, and second most recent versions of your archive.
    • etc.
  • Your script should:
    • Delete all unnecessary archives (all archives minus the number to keep) in the versions folder
    • Delete all unnecessary archives (all archives minus the number to keep) in the /data/web_static/releases folder of both of your web servers
  • All remote commands must be executed on both of your web servers (using the env.hosts = ['', 'IP web-02'] variable in your script)
• 101-setup_web_static.pp : Redo the task #0 but by using Puppet.
