The daemon includes many configuration options, which you can pass as flags when starting Docker manually, or set in the daemon.json configuration file.

To start the Docker daemon manually with some configuration options:

$ dockerd -D --tls=true --tlscert=/var/docker/server.pem --tlskey=/var/docker/serverkey.pem -H tcp://192.168.59.3:2376

This command enables debugging (-D), enables TLS (-tls), specifies the server certificate and key (--tlscert and --tlskey), and specifies the network interface where the daemon listens for connections (-H).

i am getting the below error when i ran this

chmod /var/lib/docker: operation not permitted

can you plese help on this query.

If you are running containers with Docker, it implies running the Docker daemon. This daemon currently requires root privileges. To avoid this try to run with root access or set permission for that file.

$ chmod +x /var/lib/docker
