y-api
About y-api service
The service provides domain categorization services and can be used both locally and in a distributed system. In the latter case, the speed of receiving a response decreases due to network delays.
A stable connection to the Internet is required for the uninterrupted operation of the service:
- loading the database and updating it
- sending counter_cat and counter_unknown_cat values
- sending additional information about the instance with the container
Stats are sent every 5 minutes.
The performance of the y-api service varies approximately from 70k to 150k requests per second. The performance depends on the number of domains and threads addressing the y-api. It operates based on a parallel server architecture, where a thread is created upon the arrival of a request.
Using y-api service
Starting the service
1. Install docker.
2. Load the archive with the container image with sudo docker load -i y_api.tar.gz
3. Run the image in the docker subnet.
3.1 Alternatively, create a separate subnet
sudo docker network create --driver=bridge --subnet=193.33.33.0/24 y-api-net
and run the container
sudo docker run -it -d --net y-api-net --ip 193.33.33.33 y-api:1
4. Check the service with curl http://193.33.33.33/qwerty.com
193.33.33.33 is an example, you can use any other network.
Service response: {"category": [36, 49], "bad": false, "category_name": ["Education", "Computers & Internet"]}
ATTENTION! The request counter is sent every 5 minutes. Check time must be shorter so the data is not sent to the statistics server for billing.
Logging is done to stdout and stderr.
The supported request is GET.
