2. Put the restore.sh script near it.

3. Follow the script below:

# Providers :- discover the services that live on your infrastructure (their IP, health, ...)
# Entrypoints :- listen for incoming traffic (ports, ...)
# Routers :- analyse the requests (host, path, headers, SSL, ...). A router is in charge of connecting incoming requests to the services that can handle them.
# Services :- forward the request to your services (load balancing, ...). The Services are responsible for configuring how to reach the actual services that will eventually handle the incoming requests.
# Middlewares :- may update the request or make decisions based on the request (authentication, rate limiting, headers, ...)
