nginx

 Architecture multi-instances Mattermost

1. Côté Docker (tu dis savoir faire, mais je résume) :

Chaque instance doit avoir :

• Son propre docker-compose.yml dans un dossier séparé
• Son propre .env avec des valeurs uniques :

# ===== INSTANCE 1 : groupe.aubaygues.fr =====
# Fichier : /etc/nginx/sites-available/mattermost-instance1.conf

upstream backend_instance1 {
    server localhost:8065;
    keepalive 64;
}

server {
    listen 80;
    server_name groupe.aubaygues.fr;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    server_name groupe.aubaygues.fr;

    ssl_certificate /etc/letsencrypt/live/groupe.aubaygues.fr/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/groupe.aubaygues.fr/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

    location ~ /api/v[0-9]+/(users/)?websocket$ {
        proxy_set_header Upgrade $http_upgrade;

    }

}

upstream backend_instance2 {
    server localhost:8066;  # Port différent !
