+===== Redis for Authelia session =====
+Authelia stores session data in memory by default. This means whenever the container or server is restarted, all users will have to log in again as the session data is lost. To store data across restarts, Redis can be used as in memory database and cache.
+Authelia docker compose file should be adjusted as following:
+<code yaml>
+name: authelia
+services:
+  authelia:
+    image: authelia/authelia
+    container_name: authelia
+    restart: unless-stopped
+    volumes:
+      - /opt/authelia:/config
+    ports:
+      - 6091:9091
+    environment:
+      - TZ=Europe/London
+    depends_on:
+      redis:
+        condition: service_started
+  redis:
+    image: redis:alpine
+    container_name: authelia-redis
+    command: >
+      redis-server
+      --appendonly yes
+      --appendfsync everysec
+      --save 900 1
+      --save 300 10
+      --save 60 10000
+    volumes:
+      - /opt/authelia/redis:/data
+    restart: unless-stopped
+</code>
+And in /opt/authelia/configuration.yml add redis to the session section:
+<code>
+session:
+  redis:
+    host: authelia-redis
+    port: 6379
+</code>
+Then stop and fully restart the authelia container.
