Docker Basics on a NavEdge Edge Server: Run Your First Container

Step by step

1. Check Docker

   Confirm the engine is running and your user may use it.

   docker version
   docker info --format '{{.ServerVersion}} {{.Driver}}'
   

2. Pull an image by version

   Always pin a version tag instead of latest, so every site runs the same software.

   docker pull nginx:1.27-alpine
   

3. Run it

   Give the container a name, publish a port, and set it to restart after a reboot or crash.

   docker run -d --name web --restart unless-stopped -p 8080:80 nginx:1.27-alpine
   

4. Check it

   List containers, read the logs and test the port.

   docker ps
   docker logs --tail 50 web
   curl -I http://localhost:8080
   

5. Update it

   Pull the new version, remove the old container and start the new one. Data in volumes is kept.

   docker pull nginx:1.27.3-alpine
   docker rm -f web
   docker run -d --name web --restart unless-stopped -p 8080:80 nginx:1.27.3-alpine
   

6. Clean up

   Remove unused images to keep the edge server's disk free.

   docker image prune -a --filter "until=168h"
   

Commands are generic, industry-standard examples. Exact syntax and menu names vary by model and firmware; check your device's manual on the Documentation page.
