How Do I upgrade Docker

rated 0 times [ 156] [ 0] / answers: 1 / hits: 388445 / 2 Years ago, thu, december 16, 2021, 2:55:51

I type docker.io version, and get:

Client version: 0.9.1

Go version (client): go1.2.1

Git commit (client): 3600720

Server version: 0.9.1

Git commit (server): 3600720

Go version (server): go1.2.1

Last stable version: 0.11.1, please update docker

I follow that with an apt-get update, then either: apt-get upgrade, or apt-get upgrade docker.io, but all it gives me is:

docker.io is already the newest version.

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I'm running Ubuntu 14.04 (trusty) 64bit server.

EDIT: I think I used a script in this Post comment to install docker (since it purported to allow me to just type docker instead of docker.io)

Suppose it is Ubuntu Trusty (14.04) release, which has 0.9.1 officially

Update again in 2017/03/07 to reflect to the changes in new release, see https://blog.docker.com/2017/03/docker-enterprise-edition/

Official guideline is here Install docker for Ubuntu, old release had different package name.

docker.io: is used to be very old version in default ubuntu repo (can skip here)

docker-engine: is used before release 1.13.x

docker-ce: since 17.03

for docker-engine

# add the new gpg key

$ sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

# add new repo

$ sudo add-apt-repository 

  "deb [arch=amd64] https://download.docker.com/linux/ubuntu 

  $(lsb_release -cs) 

  stable"

Then you can smoothly upgrade to latest docker version

$ sudo apt-get update



# remove the old

$ sudo apt-get purge lxc-docker*



# install the new

$ sudo apt-get install docker-engine

And in the case that you don't want to install latest package then you can do something like below.

$ sudo apt-get install docker-engine=1.7.1-0~trusty

for docker-ce

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

$ sudo add-apt-repository 

  "deb [arch=amd64] https://download.docker.com/linux/ubuntu 

  $(lsb_release -cs) 

  stable"

$ sudo apt-get update

$ sudo apt-get install docker-ce
