Docker. no such file or directory / Is your docker daemon up and running?

Small problem with docker start.

Sometimes when we execute this:

sudo docker run hello-world

We revise this:

Post http:///var/run/docker.sock/v1.20/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?
* Is your docker daemon up and running?

Then we can fix that by:

cd /etc/init.d
sudo start docker

Correct output for that command is

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Hello from Docker.
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
