Docker installation and ease of use

1. Installation of Docker

( "Installing Docker" here is actually installing Docker Engine)

$ sudo apt-get intasll Docker.io

• Note:apt-get is a management tool for Ubuntu installation software

2. Verify that the Docker engine is installed successfully

# Check that you have a working install

$ sudo docker info

3. Download an image (Download a pre-built image)

# Download an Ubuntu image

$ sudo docker pull Ubuntu

• Ubuntu is the name of the image, and you can search for the desired image in the Docker hub

4. Running an interactive shell

$ sudo docker run-it ubuntu/bin/bash

• -I flag starts an interactive container.
• -T flag creates a pseudo-tty that attaches and stdinstdout

5. Save a volume container as an image

• If the changes to Docker are not software installed with Jupyter, but only some packages are installed, then saving the new image requires only

sudo docker commit Containerid newimagename

• Containerid is the ID of the container to be saved
• Newimagename is the name of the new image, such as the name Ting/caffe:version1, where Version1 is the flag of the new container, which can be used to identify the version information of the new image

6. Enter the running container

exec-it c18652dcc369 Bash
