# Tag, push, and pull your image
|
|
|
|
In this section, you tag and push your `docker-whale` image to your newly
|
|
created repository. When you are done, you test the repository by pulling your
|
|
new image.
|
|
|
|
## Step 1: Tag and push the image
|
|
|
|
If you don't already have a terminal open, open one now:
|
|
|
|
1. Go back to your command line terminal.
|
|
|
|
2. At the prompt, type `docker images` to list the images you currently have:
|
|
|
|
$ docker images
|
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
|
docker-whale latest 7d9495d03763 38 minutes ago 273.7 MB
|
|
<none> <none> 5dac217f722c 45 minutes ago 273.7 MB
|
|
docker/whalesay latest fb434121fc77 4 hours ago 247 MB
|
|
hello-world latest 91c95931e552 5 weeks ago 910 B
|
|
|
|
5. Find the `IMAGE ID` for your `docker-whale` image.
|
|
|
|
In this example, the id is `7d9495d03763`.
|
|
|
|
Notice that currently, the `REPOSITORY` shows the repo name `docker-whale`
|
|
but not the namespace. You need to include the `namespace` for Docker Hub to
|
|
associate it with your account. The `namespace` is the same as your Docker
|
|
Hub account name. You need to rename the image to
|
|
`YOUR_DOCKERHUB_NAME/docker-whale`.
|
|
|
|
6. Use `IMAGE ID` and the `docker tag` command to tag your `docker-whale` image.
|
|
|
|
The command you type looks like this:
|
|
|
|
|
|
|
|
Of course, your account name will be your own. So, you type the command with
|
|
your image's ID and your account name and press RETURN.
|
|
|
|
$ docker tag 7d9495d03763 maryatdocker/docker-whale:latest
|
|
|
|
7. Type the `docker images` command again to see your newly tagged image.
|
|
|
|
$ docker images
|
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
|
maryatdocker/docker-whale latest 7d9495d03763 5 minutes ago 273.7 MB
|
|

|
|
<none> <none> 5dac217f722c 5 hours ago 273.7 MB
|
|
docker/whalesay latest fb434121fc77 5 hours ago 247 MB
|
|
hello-world latest 91c95931e552 5 weeks ago 910 B
|
|
|
|
8. Use the `docker login` command to log into the Docker Hub from the command line.
|
|
|
|
The format for the login command is:
|
|
|
|
docker login --username=yourhubusername --email=youremail@company.com
|
|
|
|
When prompted, enter your password and press enter. So, for example:
|
|
|
|
$ docker login --username=maryatdocker --email=mary@docker.com
|
|
Password:
|
|
WARNING: login credentials saved in C:\Users\sven\.docker\config.json
|
|
Login Succeeded
|
|
|
|
9. Type the `docker push` command to push your image to your new repository.
|
|
|
|
$ docker push maryatdocker/docker-whale
|
|
The push refers to a repository [maryatdocker/docker-whale] (len: 1)

|
|
|
|
10. Return to your profile on Docker Hub to see your new image.
|
|
|
|
|
|
|
|
## Step 2: Pull your new image
|
|
|
|
In this last section, you'll pull the image you just pushed to hub. Before you
|
|
do that though, you'll need to remove the original image from your local
|
|
machine. If you left the original image on your machine. Docker would not pull
|
|
from the hub — why would it? The two images are identical.
|
|
|
|
1. Make sure Docker is running, and open a command line terminal.
|
|
|
|
2. At the prompt, type `docker images` to list the images you currently have on your local machine.
|
|
|
|
$ docker images
|
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE

|
|

|
|
hello-world latest 91c95931e552 5 weeks ago 910 B
|
|
|
|
To make a good test, you need to remove the `maryatdocker/docker-whale` and
|
|
`docker-whale` images from your local system. Removing them forces the next
|
|
`docker pull` to get the image from your repository.
|
|
|
|
3. Use the `docker rmi` to remove the `maryatdocker/docker-whale` and `docker-whale`
|
|
images.
|
|
|
|
You can use an ID or the name to remove an image.
|
|
|
|
$ docker rmi -f 7d9495d03763
|
|
$ docker rmi -f docker-whale
|
|
|
|
4. Pull and load a new image from your repository using the `docker run` command.
|
|
|
|
The command you type should include your username from Docker Hub.
|
|
|
|
docker run yourusername/docker-whale
|
|
|
|
Since the image is no longer available on your local system, Docker downloads it.
|
|
|
|
$ docker run maryatdocker/docker-whale
|
|
Unable to find image 'maryatdocker/docker-whale:latest' locally
|
|
latest: Pulling from maryatdocker/docker-whale

|
* run a software image in a container
|
|
* located an interesting image on Docker Hub
