When I create a node with docker-machine
docker-machine create -d virtualbox node1
it is created with tls verification enabled for docker deamon which made things a bit more of a hassle than normal for swarm.
I want to create a node with docker-machine without tls verification for testing purpose.
I tried with:
docker-machine create -d virtualbox --engine-tls false node1
and
docker-machine create -d virtualbox --engine-tls-verify false node1
and
docker-machine create -d virtualbox --engine-opt-tls false node1
on the Notification bar, select Settings from the context menu, and then select the Expose daemon on tcp://localhost:2375 without TLS checkbox in the General section of your system Docker settings.
If you need Docker to be reachable through HTTP rather than SSH in a safe manner, you can enable TLS (HTTPS) by specifying the tlsverify flag and pointing Docker's tlscacert flag to a trusted CA certificate. In the daemon mode, it only allows connections from clients authenticated by a certificate signed by that CA.
DOCKER_TLS_VERIFY is a environment variable and not a docker daemon config file options. See: https://docs.docker.com/engine/reference/commandline/dockerd/#/daemon-configuration-file for the documentation.
sock is basically the Unix socket the Docker daemon listens on by default. It is also a tool used to communicate with the Docker daemon from within a container. Sometimes, containers need to bind mount the /var/run/docker. sock file. Communication with container from docker daemon.
I use commands below:
docker-machine create -d virtualbox --engine-env DOCKER_TLS=no node1
And then ssh to the node to execute docker commands:
docker-machine ssh node1
$ docker info
try:
docker-machine create -d virtualbox --engine-opt tlsverify=false node1
and after running:
eval "$(docker-machine env node1)"
run:
unset DOCKER_TLS_VERIFY
This worked best for me:
docker-machine create -d virtualbox --engine-env DOCKER_TLS=no --engine-opt host=tcp://0.0.0.0:2375 node1
This way it binds to 2375 in addition to 2376. 2375 is the tradition for non-tls daemons.
