+# Dockge
+To manage our containers, we'll rely on docker compose and use `Dockge` to manage those composes or "stacks".
+Dockge is lightweight, doesn't use any databases and relies solely on compose.yaml files.
+This gives me the opportunity to better learn to design and understand Docker components without abstracting them away.
+It also stores all compose files locally in plaintext which helps if I ever want to migrate away from Dockge.
+
+## Setup
+We'll create a dedicated folder for Dockge inside our directory dedicated to Docker containers:
+```bash
+mkdir -p /opt/appdata/dockge
+cd /opt/appdata/dockge
+```
+Next we'll define its compose.yaml file.
+```bash
+nano compose.yaml
+```
+And paste the following into it:
+```yml
+services:
+  dockge:
+    image: louislam/dockge:1
+    container_name: dockge
+    restart: unless-stopped
+    ports:
+      - "5001:5001"
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock
+      - /opt/appdata/dockge/data:/app/data
+      - /opt/appdata:/opt/appdata # Mount our directory for Docker containers data
+    environment:
+        # Where to create our stacks
+      - DOCKGE_STACKS_DIR=/opt/appdata
+```
+
+Finally, we start Dockge (in detached mode):
+```bash
+docker compose up -d
+```
+From now on, this should be about the only time we'll directly use `docker compose` in the CLI.
