Nginx config not working on my docker container - laravel

Question

I'm new with dockers.
I'm studying this docker-compose.yml in order to create a this three containers for webserver, workspace for my laravel and the db. And I'm understanding most of it.
It builds just fine but on localhost I get the nginx default page, not my laravel public folder.
I have a app.conf file inside of /nginx/conf.d/
server {
listen 80;
index index.php index.html;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /var/www/public;
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass app:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
location / {
try_files $uri $uri/ /index.php?$query_string;
gzip_static on;
}
}

Answer 1

Found the problem.
Seems that the "app" part on this line "fastcgi_pass app:9000;" on my app.conf should be the name of my workspace container.
So like this it works.
server {
listen 80;
index index.php index.html;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /var/www/public;
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass myapp-workspace:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
location / {
try_files $uri $uri/ /index.php?$query_string;
gzip_static on;
}
}
