The bottom line is that I need to replace the pod with php code in the kubernetes cluster with a docker container using telepresence, this pod contains 2 containers: php and nginx.
I do everything according to the instructions (https://www.telepresence.io/tutorials/php) but it seems kubernetes does not see my container.
I run the cluster locally on minikube version 1.16.0, kubernetes version 1.20.0. I am using the NodePort service to access the application. After swap the pod, I get a 404 error.
This is how I find the external address: addr = kubectl get nodes -o jsonpath='{ $.items[*].status.addresses[?(@.type=="InternalIP")].address }'
Target browser address: addr + :30000
Spoof command: telepresence --swap-deployment telepresence-php --docker-run --rm -v$(pwd)/web:/var/www/html telepresence-dev

docker container with which I substitute the php + nginx pod.
FROM nanoninja/php-fpm:latest
RUN apt-get update && apt-get install nginx -y
ADD ./etc/nginx/default.conf /etc/nginx/conf.d/default.conf
RUN rm /etc/nginx/sites-enabled/default
CMD nginx && php-fpm
Nginx default.conf settings:
server {
listen 80 default_server;

}

}
Help if it's not difficult. The demo project is here https://github.com/Mavellol/kuber-nginx-php-mysql
