I am using Windows 10 x64 and just downloaded Docker, I tried running a simple "hello-world" dockerfile but I kept getting an error:
docker: Error response from daemon: error creating temporary lease: file resize error: truncate /var/lib/desktop-containerd/daemon/io.containerd.metadata.v1.bolt/meta.db: read-only file system: unknown.
Every time I try, I get the same file read-only error.
If I remember correct after clearing space and Restarting Docker from scratch worked for me.
On windows, open Docker desktop and click on the debug icon then restart. You can also consider "reset to factory defaults"
In my case the problem was conflicting mounts in docker compose:
webserver:
image: nginx:latest
ports:
- 80:80
- 443:443
restart: always
volumes:
- ./services/nginx/static/:/var/www/:ro
- ./services/certbot/www:/var/www/certbot/:ro
chaged it to:
webserver:
image: nginx:latest
ports:
- 80:80
- 443:443
restart: always
volumes:
- ./services/nginx/static/:/var/www/PUBLIC:ro
- ./services/certbot/www:/var/www/certbot/:ro
/usr/local/share/myfolder, then /usr/local/share/myfolder/demo/index.html, but the demo folder didn't exist inside myfolder. After creating demo inside the folder on the host that was bind-mounted to /usr/local/share/myfolder, it worked.
./services/nginx/static/certbot in this case.My case the reason is a corrupted SSD. When you see the error, check dmesg. Mine is brutal:

Go to "Docker Desktop"-> "Settings" Go to "Resources"->"File Sharing" Add your project folder
docker infoand also check if your drive C: has enough free space (20+ GB). Docker is not complicated. Windows is complicating it.
