install Docker CE

安裝Docker CE 有多種方式,根據(jù)你的需要有一下幾種:

• 1.大多數(shù)用戶使用docker倉(cāng)庫(kù)安裝,是一種安裝和升級(jí)簡(jiǎn)單的任務(wù).這也是推薦的方式
• 2.一些用戶下載DEB包并手動(dòng)安裝和完全人工管理升級(jí).在某些情境下是有用的,例如:在air-gapped系統(tǒng)且沒有網(wǎng)絡(luò)的環(huán)境下安裝docker
• 3.在測(cè)試和開發(fā)環(huán)境中,一些用戶選擇使用自動(dòng)化 convenience scripts 腳本安裝docker

1. 使用倉(cāng)庫(kù)安裝docker
   Before you install Docker CE for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.

設(shè)置倉(cāng)庫(kù)

1. update the apt package index:

$ sudo apt-get update

2. Install packages to allow apt to use a repository over HTTPS:

$ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

3.Add Docker’s official GPG key:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Verify that you now have the key with the fingerprint
9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.

$ sudo apt-key fingerprint 0EBFCD88
    
pub   rsa4096 2017-02-22 [SCEA]
      9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <docker@docker.com>
sub   rsa4096 2017-02-22 [S]

4. Use the following command to set up the stable repository. To add the nightly or testrepository, add the word nightly or test (or both) after the word stable in the commands below. Learn about nightly and test channels.

Note: The lsb_release -cs sub-command below returns the name of your Ubuntu distribution, such as xenial. Sometimes, in a distribution like Linux Mint, you might need to change $(lsb_release -cs) to your parent Ubuntu distribution. For example, if you are using Linux Mint Tessa, you could use bionic. Docker does not offer any guarantees on untested and unsupported Ubuntu distributions.

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

INSTALL DOCKER CE

1.Update the apt package index.

$ sudo apt-get update

2.Install the latest version of Docker CE and containerd, or go to the next step to install a specific version:

$ sudo apt-get install docker-ce docker-ce-cli containerd.io

Got multiple Docker repositories?
If you have multiple Docker repositories enabled, installing or updating without specifying a version in the apt-get install or apt-get update command always installs the highest possible version, which may not be appropriate for your stability needs.

3.To install a specific version of Docker CE, list the available versions in the repo, then select and install:
a. List the versions available in your repo:

$ apt-cache madison docker-ce

  docker-ce | 5:18.09.1~3-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu  xenial/stable amd64 Packages
  docker-ce | 5:18.09.0~3-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu  xenial/stable amd64 Packages
  docker-ce | 18.06.1~ce~3-0~ubuntu       | https://download.docker.com/linux/ubuntu  xenial/stable amd64 Packages
  docker-ce | 18.06.0~ce~3-0~ubuntu       | https://download.docker.com/linux/ubuntu  xenial/stable amd64 Packages
  ...

b. Install a specific version using the version string from the second column, for example, 5:18.09.1_3-0ubuntu-xenial.

$ sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io

4.Verify that Docker CE is installed correctly by running the hello-world image.

$ sudo docker run hello-world

This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.

Docker CE is installed and running. The docker group is created but no users are added to it. You need to use sudo to run Docker commands. Continue to Linux postinstall to allow non-privileged users to run Docker commands and for other optional configuration steps.

UPGRADE DOCKER CE

To upgrade Docker CE, first run sudo apt-get update, then follow the installation instructions, choosing the new version you want to install.

Uninstall Docker CE

1.Uninstall the Docker CE package:

$ sudo apt-get purge docker-ce

2.Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes:

$ sudo rm -rf /var/lib/docker

You must delete any edited configuration files manually.
