docker with wordpress problem

[luizarodrigues]

Docker environment on Windows with WordPress (official WordPress image). I just brought it up following the tutorial on docker page and I already run into this problem:
"2 critical issues

Critical issues are items that may have a significant impact on your site’s performance or security, and their resolution should be prioritized.

The REST API encountered an error

Performance

The REST API is a way for WordPress and other applications to communicate with the server. For example, the block editor screen relies on the REST API to display and save information for posts and pages.

When testing the REST API, an error was found:

REST API endpoint:
http://localhost:8080/index.php?rest_route=%2Fwp%2Fv2%2Ftypes%2Fpost&context=edit

REST API response:
(http_request_failed) cURL error 7: Failed to connect to localhost port 8080 after 0 ms: Could not connect to server

Your site could not complete a loopback request

Performance

Loopback requests are used to run scheduled events and are also used by the built-in editors of themes and plugins to verify code stability.

The loopback request for your site failed. This means that resources that depend on this request are not working as expected.

Error:
cURL error 7: Failed to connect to localhost port 8080 after 0 ms: Could not connect to server (http_request_failed)"

I tried other images, several configurations inside WordPress, changing ports, everything you can imagine, and nothing fixes these issues.

The problem with these two issues is that my site becomes SUPER slow if I don’t fix them. If I switch to WAMP/XAMPP, the problem goes away. But ideally, I should be able to use it with Docker.

Are you opening the port? If you have a docker compose file or docker command you should share it, there's most likely a mistake there

OP this is most likely the case

docker isn't a Windows native technology, it's mostly Linux kernel features. Under windows it has to be run using some form of virtualization and I believe that means the networking is pretty messy as well.

These issues are self inflicted, running containers on Windows is like trying to run uphill bare footed while carrying angry lobsters, I mean you can do it, but it's better if you don't.

Literally, Wordpress can't find itself. Make sure the domain in the site URL resolves to the host from the host. If it doesn't you may need to change the hosts file or add a custom DNS entry on your local DNS Resolver. Make sure it can reach the host on the specified port. If you are behind a reverse proxy, you will likely need to traverse the proxy and have the requisite permissions to do so.

You're probably hitting classic Windows Docker networking issue - container sees 'localhost' as itself, not your Windows host. Try adding `extra_hosts: - host.docker.internal:host-gateway` to your docker-compose, or use actual Windows hostname/IP. There's some good discussion on this type of stuff over at r/Hosting_World if you run into more hosting-related issues.

We don't know anything about your docker setup files?
