Hello Hasitha Kaushan, glad it helped you!
If you have deployed according to this guide, which is basically the following command:
docker run — name mathflake_api -p 80:80 -d registry.gitlab.com/mathflake/api
The API should be accessible on port 80 of the machine it was deployed to. Since port 80 is the default port for HTTP request, you should reach the API by entering the IP address of your server in a browser.
Let me know if this was sufficient.
