Actions

1. Corriger portainer.33800.nowhere84.com → PROD

Modifier /etc/nginx/sites-available/portainer.33800.nowhere84.com.conf :

- proxy_pass https://192.168.1.51:9443;
+ proxy_pass https://192.168.1.12:9443;

2. Creer portainer-dev.33800.nowhere84.com

server {
    listen 80;
    server_name portainer-dev.33800.nowhere84.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name portainer-dev.33800.nowhere84.com;

    ssl_certificate /etc/letsencrypt/live/33800.nowhere84.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/33800.nowhere84.com/privkey.pem;
    ssl_protocols TLSv1.2 TLSv1.3;

    location / {
        proxy_pass https://192.168.1.51:9443;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

    access_log /var/log/nginx/portainer-dev.access.log;
    error_log /var/log/nginx/portainer-dev.error.log;
}

3. Creer prometheus.33800.nowhere84.com

server {
    listen 80;
    server_name prometheus.33800.nowhere84.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name prometheus.33800.nowhere84.com;

    ssl_certificate /etc/letsencrypt/live/33800.nowhere84.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/33800.nowhere84.com/privkey.pem;
    ssl_protocols TLSv1.2 TLSv1.3;

    location / {
        proxy_pass http://192.168.1.12:9090;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    access_log /var/log/nginx/prometheus.access.log;
    error_log /var/log/nginx/prometheus.error.log;
}
