To install the latest version of Docker you need to use a Docker source to install

$ sudo su-root

# Apt-get-y Installapt-transport-https

# apt-keyadv--keyserver hkp://keyserver.ubuntu.com:80--recv-keys 36a1d7869245c8950f966e92d8576a8ba88d21e9

# bash-c "Echo Debhttps://get.docker.io/ubuntu Docker main >/etc/apt/sources.list.d/docker.list"

# Apt-get Update

# apt-get-y Install Lxc-docker

# docker-v// View the Docker version

# Ps-ef | grep Docker

Third, the old version of Docker upgrade

Note: Docker installed with Ubuntu Source cannot be upgraded to the latest version, because the Ubuntu source is not the latest version of Docker

Note: All running containers in the upgrade are automatically closed, preferably before upgrading the container.

# apt-getupdate

Here are two ways to upgrade:

# apt-get-u-y upgrade Lxc-docker Security Upgrades

# apt-get-u-y dist-upgrade lxc-docker A security upgrade failure can be used to resolve a dependency package upgrade

# docker-v// View the Docker version
