I am dealing with an issue where the first request towards my Google Cloud Run container results in a 502 Bad Gateway error. The following can be seen in the logs:
[crit] 23#23: *3 connect() to unix:/run/php/php7.4-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 169.254.8.129, server: domain.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.4-fpm.sock:", host: "my.domain.com"
However, on the second request it works fine.
I am using supervisord together with php-fpm and nginx.
