So I have a docker container build with buildpack that runs the following command under PID 1
procmgr /layers/paketo-buildpacks_php-web/php-web/procs.yml
is it possible to reload the configs passed into procmgr somehow?

At the time of writing this, no. The procmgr cli that is used here is very basic.
https://github.com/paketo-buildpacks/php-web/blob/main/cmd/procmgr/main.go
It loads the processes information listed in procs.yml, starts those processes, redirects all STDOUT/STDERR, and watches for a process to exit. If one process exits, then they all exit. There's no reload capability.
If you need to reload the information in procs.yml, you'll need to reload your container.

Supervisor is not started into my container and i am not able to run my php artisan queue:work command for my laravel project.
Extract from my Dockerfile
# Add worker to supervisor config file
COPY laravel-worker.conf /etc/supervisor/conf.d/
CMD ["/usr/bin/supervisord"]
Here is the laravel-worker.conf:
[program:laravel-worker]
command=php /var/www/test/current/artisan queue:work --tries=3
user=myuser
process_name=%(program_name)s_%(process_num)d
directory=/var/www/test/current
stdout_logfile=/tmp/supervisord.log
redirect_stderr=true
numprocs=1
autostart=true
autorestart=true
When i go into the container, the supervisor service is not started:
root#e7227ef40f63:/# service supervisor status
supervisord is not running.
And process are following:
root#e7227ef40f63:/# ps -aux | grep supervisor
root 1 0.0 0.0 4328 652 ? Ss 18:21 0:00 /bin/sh -c service ssh restart && service apache2 restart && service cron start && bash /usr/bin/supervisord

root 380 0.0 0.0 11120 712 ? S+ 18:27 0:00 grep supervisor
UPDATE
I edited my DockerFile and put this line:
ENTRYPOINT service ssh restart && service apache2 restart && service cron start && /usr/bin/supervisord && bash
The service is now well started when the container starts :

But it seams that supervisor doesn't start my config file because i don't see the 8 processes that should be run..
This is the bad part:
&& bash /usr/bin/supervisord
supervisord is not a bash script. Execute it as is: && /usr/bin/supervisord.
However, I recommend you to completely avoid using service in a container. In general, running more than one process into a container is considered an antipattern, but if you really need it, better only use supervisor . Create a .conf file for each process (cron, sshd, etc) and only run supervosord as is in your CMD.
I want to generate a file by batch.php, which is linked to the button in this page:
<?php
echo "Hello world!";
'cat 123 > uploads/cat.txt';
echo "Bye world!";
?>
Clicking on the button does launch batch.php, however, cat.txt is NOT generated on the server side.
Does anyone know how to fix this? Maybe I need to setup some permission for the folder?
Edit 1:

I granted 777 to uploads, and I tried all the possible owner names and owner groups (ie, timur:timur, www-data:www-data and root:root), but none of them works...
The key is to write exec('cat 123 > uploads/cat.txt') or shell_exec('cat 123 > uploads/cat.txt') instead of 'cat 123 > uploads/cat.txt'.
Then, although drwxrwxrwx 2 timur timur 4096 Sep 12 15:03 uploads works, assigning 755 and www-data:www-data (reserved to PhP) to uploads is more correct.
I am having some permission issues with Nginx and Php fastcgi when trying to get to the php file. I am using 5.5.15 and Nginx 1.6.0 in Redhat 7 .
My php file is very simple for now.
<?php
echo "\nscript owner : ".get_current_user()."\n";
$myFile = '/usr/share/nginx/html/test.log';
$fh = fopen($myFile, 'a') or die("can''t open file");
?>
Get current user will result in : "myuser"
The error that I am getting is the following:
2014/08/26 22:47:14 [error] 6424#0: *16 FastCGI sent in stderr: "PHP message: PHP Warning: fopen(/usr/share/nginx/html/test.log): failed to open stream: Permission denied in /usr/share/nginx/html/test.php on line 19" while reading response header from upstream, client: XXXXXX, server: XXXXXXX, request: "GET /test.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "XXXXXXX"
Here is the permissions for the directory /usr/share/nginx( all of the parent directories have x permissions):

My Server looks like the following:
server {
listen 80;
root /usr/share/nginx/html;
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
And in the nginx.config I am using the same user: "user ec2-user;"
I have also changed the /etc/php-fpm.d/www.conf file to have the same user and group.
user = myuser
group = myuser
So, both Nginx and PHP are running on the same user "myuser".
All the directories up to where the log file and the php file are located(/usr/share/nginx/html) have x access and that user has 777 access to that html directory.
Not sure what I am missing. I have been searching online for 2 days now but no luck.
I suppose rights are correct, but you have 3 line of code in test.php, but due to error this is not true :) Check what file you run.
"in /usr/share/nginx/html/test.php on line 19"
I have a working MVC framework using codeigniter. The codebase is located in /var/www/project,
where project follows the same structure as codeigniter. I have placed a info.php file under /var/www/project, which is the basic phpinfo() script. On typing
http://localhost/project/info.php
the page displays the information as it should.
My config.php under /var/www/project/application/config has been configured so that the [base_url] is : http://localhost/project
The 'project' is trying to connect to database : 'development' and the database.php has been configured properly ( afaik). On enabling the debug mode in database.php, it doesnt throw any error which makes me think that there is no issue as far as accessing the database is conerned( Though I can be wrong).
Also doing a ' ps aux | grep apache' shows:

Usually if apache is not given the root privilege, this sort of issue might occur, but here the privilege is root. I am not sure where am I messing up the configuration part.
Any suggestion will be appreciated.
Set:
$config['base_url'] = '';
And let us know if it changes anything in the output.
Also, if you're using cookies, set the $config['cookie_path'] = "/project";
Today earlier my nginx server was 100% CPU usage, the process using all CPU was php-cgi.
I login and kill all php-cgi with this command.
kill -s 9 PID
Now after restarting my server is not working, I see the message "No input file specified.". I google this message, but nothing works, I suppose I have just to start php-cgi again, but can't find how start it.
UPDATE
If I run top command, I can see php-cgi running
