I am trying to create a php inside my docker container

However, when I go to the localhost on my browser, I keep getting the 502 bad gateway.

The error log shows

[error] 11#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: (my IP), server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost"

My nginx conf looks like this

server {
  listen       80;
  server_name  jenkins.local;
  root         /var/www/html;
  index        index.php;
  access_log   /var/log/nginx/localhost-access.log;
  error_log    /var/log/nginx/localhost-error.log;

  location / {

    try_files $uri $uri/ /index.php?$args;

  }

  location ~ \.php$ {

    try_files $uri =404;
    include /etc/nginx/fastcgi_params;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_script_name;
    fastcgi_intercept_errors on;

  }

}

I am new to docker and PHP so please let me know if I need to provide any other information.

docker jenkins php

Did you start php-fpm?

Is port 9000 open?
