Checking if Machine Default Existsa Press Any Key to Continue

1) Download and install the docker tookbox from
https://www.docker.com/products/docker-toolbox

This installs multiple products, docker engine, docker swarm, oracle virtual box, kitematics, etc.

2) Launch the Docker quick start terminal as administrator

Usually, Note: If the CPU virtualization is not enabled in the BIOS, you get the below error (). Else, you will see no errors.

Creating CA: C:\Users\<<mylogonname>>\.docker\machine\certs\ca.pem
Creating client certificate: C:\Users\<<mylogonname>>\.docker\machine\certs\cert.pem
Running pre-create checks...
Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"
Looks like something went wrong in step ´Checking if machine default exists´... Press any key to continue...

3)  Now, pulling a helloworld image from docker hub (https://hub.docker.com/)
Note: You can use the Kitematics (to perform the same using a GUI instead of command line)

docker pull kitematic/hello-world-nginx

You may run into below error.
---------------------------------
$ docker pull kitematic/hello-world-nginx
Using default tag: latest
Pulling repository docker.io/kitematic/hello-world-nginx
Network timed out while trying to connect to https://index.docker.io/v1/repositories/kitematic/hello-world-nginx/images. You may want to check your internet connection or if you are behind a proxy.

------------------------------

Don't worry, to resolve this, sometimes you need to just restart the environment

$ docker-machine restart default      # Restart the environment
$ eval $(docker-machine env default)  # Refresh your environment settings

-------------------
4) to check the list of images installed
docker images

5) to run a container from the image (nginx, a reverse proxy, load balancer server for example)
-------------------
docker run kitematic/hello-world-nginx

----------------------
6) to check the list of active containers
docker ps -a to check the status all containers

Note: use doc

7) to stop the container

docker stop <<imagename>>

docker stop nostalgic_mcclintock
-----------------------

8) to remove the container and leave the image as is

docker rm <<containerId>>

docker rm 2b

----------------------------

9) to run the container on a specific port in daemon mode for example,

docker run -d -p 5000:80 kitematic/hello-world-nginx

Here, 5000 is external port and 80 is internal port

10) You can now try launching the instance in the browser
