Nginx on docker, curl get Connection refused

I am working in a local environment with docker.
I have an nginx web container and a php container which are in the same network.

I build the php container from my own dockerfile (with phpfpm and phpcli); and, the nginx I compose it in a docker-compose from the nginx:stable hub image.

I have 2 projects: a symfony(http://i-r4y.kaiza.lh/) and a drupal(http://i-z4r4.kaiza.lh/) which runs in it. and the symfony exposes an api which have to be consumed by the drupal. The problem is that an error when I call the symfony from the drupal cURL error 7: Failed to connect to i-r4y.kaiza.lh port 80: Connection refused

I thought it was a configuration of the symfony side api route; like it must be public or accept CORS etc …

but in the php container, when I do curl either the symfony or drupal url, I have the same error.

app@kz-php74:/var/www$ curl http://i-r4y.kaiza.lh
curl: (7) Failed to connect to i-r4y.kaiza.lh port 80: Connection refused
app@kz-php74:/var/www$ curl http://i-z4r4.kaiza.lh
curl: (7) Failed to connect to i-z4r4.kaiza.lh port 80: Connection refused

I checked in the php container that the hosts are present in /etc/hosts

app@kz-php74:/var/www$ cat /etc/hosts | grep i-
127.0.0.1	i-r4y.kaiza.lh
127.0.0.1	i-z4r4.kaiza.lh

Here is the docker-compose.yml :

The nginx config of drupal:

server {
    listen 80;
    listen [::]:80;
    server_name i-z4r4.kaiza.lh;

    root /var/www/i-z4r4/web;

    resolver 127.0.0.11 ipv6=off;
    
    location @rewrite {
        rewrite ^/(.*)$ /index.php?q=$1;
    }

    # In Drupal 8, we must also match new paths where the '.php' appears in
    # the middle, such as update.php/selection. The rule we use is strict,
    # and only allows this pattern with the update.php front controller.
    # This allows legacy path aliases in the form of
    # blog/index.php/legacy-path to continue to route to Drupal nodes. If
    # you do not have any paths like that, then you might prefer to use a
    # laxer rule, such as:
    #   location ~ \.php(/|$) {
    # The laxer rule will continue to work if Drupal uses this new URL
    # pattern with front controllers other than update.php in a future
    # release.
    location ~ '\.php$|^/update.php' {
        set $fastcgi_pass "kz-php74:9000";

        fastcgi_split_path_info ^(.+?\.php)(|/.*)$;
        # Security note: If you're running a version of PHP older than the
        # latest 5.3, you should have "cgi.fix_pathinfo = 0;" in php.ini.
        # See http://serverfault.com/q/627903/94922 for details.
        include fastcgi_params;
        # Block httpoxy attacks. See https://httpoxy.org/.
        fastcgi_param HTTP_PROXY "";
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param QUERY_STRING $query_string;
        fastcgi_intercept_errors on;
        fastcgi_pass $fastcgi_pass;
    }

  ...

}

For symfony:

server {
    listen 80;
    listen [::]:80;
    server_name i-r4y.kaiza.lh;

    root /var/www/i-r4y/public;

    resolver 127.0.0.11 ipv6=off;

    location / {
        # try to serve file directly, fallback to index.php
        try_files $uri /index.php$is_args$args;
    }

    location ~ ^/index\.php(/|$) {
        set $fastcgi_pass "kz-php74:9000";

        fastcgi_pass $fastcgi_pass;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param HTTPS on;
    }

    location @rewriteapp {
        rewrite ^(.*)$ /app.php/$1 last;
    }
...
}

will anyone have any idea why this is not working?

thanks

The issue is that your DOCKER_HOST is not set to localhost, you will need to use the IP address of your docker-machine, since you are using Docker Toolbox:

docker-machine ip default # should return your IP address.

See Docker Toolbox Docs for more information.
