Keep getting Could not read CA certificate when trying to start docker

I am attempting to migrate from boot2docker to docker-machine.

I followed the directions here to install docker but I keep getting the following message:

Could not read CA certificate "/Users/<useraccountfolder>/.boot2docker/certs/boot2docker-vm/ca.pem": open /Users/<useraccountfolder>/.boot2docker/certs/boot2docker-vm/ca.pem: no such file or directory

when I run most any docker command.

Solution

  • I found my solution here

    I needed to update my .bash_profile to look like:

    export DOCKER_HOST=tcp://192.168.99.100:2376
export DOCKER_MACHINE_NAME=default
export DOCKER_TLS_VERIFY=1
export DOCKER_CERT_PATH=~/.docker/machine/machines/default

    and then run the following to generate the missing ca.pem:

    docker-machine regenerate-certs default

    I posted this in case this could help anyone else. Thanks/props go to everyone in that thread on github which was found after an hour of pain.
