Docker hello-world does not work

Operating System: Mac OS X

I installed boot2docker and started it, some errors are shown:

wangyaos-MBP-2:~ wangyao$ boot2docker start

Waiting for VM and Docker daemon to start...
..........................o
Started.

To connect the Docker client to the Docker daemon, please set:

Post http:///var/run/docker.sock/v1.19/containers/create: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?

What do I need to do to make $ docker run hello-world work?

Solution

  • Instead of running boot2docker shellinit, you need to do the following in your current shell:

    eval "$(boot2docker shellinit)"

    The boot2docker shellinit command prints the required export statements to standard out. These statements set the required environment variables for connecting to the boot2docker virtual machine.

    By wrapping the output of boot2docker shellinit with eval $(), the variables will be exported in the current shell instead of just printed. This should allow you to connect to the boot2docker vm, which is required for running the example.
