Hi @rucciva have you resolve issue with mirrord and php-fpm. I am looking for how to create mirrord with k8s and php-fpm with laravel project. How did you resolve your issue, have you use docker-compose or install php-fpm in local environment?

@cslamar here are the feature section of my config. The main point is so that outgoing connection from local nginx to local php-fpm does not get intercepted by mirrord. (note that my nginx and php-fpm container are communicating through local network, both on the kubernetes and local docker compose)

nginx:

feature:
    network:
        incoming:
            mode: steal
        outgoing:
            ignore_localhost: true
    fs: false
    env:
        include: "*"

php-fpm:

feature:
    fs: false
    env:
        include: "*"

and the command to inject nginx correctly needs to be separated into two mirrord execution, since it encountered panic when injecting shell script and the nginx won’t start

/opt/mirrord/bin/mirrord exec -f /opt/mirrord/etc/mirrord-backend-nginx.yaml /docker-entrypoint.sh -- nginx -v
exec /opt/mirrord/bin/mirrord exec -f /opt/mirrord/etc/mirrord-backend-nginx.yaml nginx -- -g "daemon off;"

Thanks for the info! I think this is related to #1655.
