two way to run a container

• The Ops perspective
• The Dev perspective

---

Start The Ops Perspective

If you are working from a freshly installed Docker host it will have no images and will look like the output above. Getting images onto your Docker host is called “pulling”. If you are following along with Linux, pull the ameenalam/nodeapp:latest.

To pull an image

docker pull <image_name>:<tag>

$ docker image pull ameenalam/nodeapp:latest

Docker images list

$ docker image ls

Run Container

docker run -d --name <container_name> -p <host_port>:<container_port> <image_name>:<tag>

$ docker container run -d --name=web2 -p=7000:8080 ameenalam/nodeapp:latest

For Test

$ curl http://localhost:7000

Open a web browser and navigate to the DNS name or IP address of the host that you are running the container from and point it to port 7000. You will see the following web page.

http://localhost:7000/

Push images to Docker Cloud

Docker Cloud uses Docker Hub as its native registry for storing both public and private repositories. Once you push your images to Docker Hub, they are available in Docker Cloud.

In order to get you started, let us get you a Docker ID.

https://hub.docker.com/

Docker login

Log in to Docker Cloud using the docker login command.

$ docker login

Tag Image

Tag your image using docker tag.

$ docker tag image_name username/image_name

Push your image to Docker Hub

Push your image to Docker Hub using docker push (making the same replacements as in the previous step).

$ docker push username/image_name

Check that the image you just pushed appears in Docker Cloud. Go to Docker Cloud and navigate to the Repositories tab and confirm that your image appears in this list.
