docker-auth.js Generate Certs


unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file: hosts: (from flag: [fd://], from file: [unix:///var/run/docker.sock tcp://])

systemctl list-units
we'll find "docker.service"

systemctl cat docker.service

first line: "# /lib/systemd/system/docker.service"

problem: ExecStart=/usr/bin/dockerd -H fd://

remove -H fd:// (comment out is not enough)

systemctl daemon-reload
systemctl restart docker.service


docker -H localhost:2376 --tlsverify --tlscacert=ca.pem --tlscert=client-microtest-cert.pem --tlskey=client-microtest-key.pem ps

docker-runc list
docker-runc exec -t 919ba26dd4ddb9d2505c1533247d181f7e732ea5eb56d856d281ce471cef03d3 cat /data/log.log > /home/kevin/log3.log
