Ubuntu and updating Docker

Question

I am trying to run the latest stable version of docker and docker-compose.

I am following the instructions on https://docs.docker.com/engine/installation/linux/ubuntulinux/

Apparently the current version of docker-compose is 1.7.

Yet, after running through the documentation, installing docker-engine, I then get:

$ docker-compose --version docker-compose version: 1.4.0 

And

$ docker --version Docker version 1.11.1, build 5604cbe 

When I try to update it, I get the following:

$ sudo apt-get upgrade docker-engine Reading package lists... Done Building dependency tree        Reading state information... Done Calculating upgrade... docker-engine is already the newest version. Done 

Update

This just keeps getting stranger. After trying all of the advice below, I now get this:

$ docker-compose -v The program 'docker-compose' is currently not installed. You can install it by typing: sudo apt-get install docker-compose anton@Charles:~$ sudo apt-get install docker-compose Reading package lists... Done Building dependency tree        Reading state information... Done docker-compose is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 

How then can I update docker?

Answer 1

Since I lost half an hour on this, maybe it will help some people out there. What I had to do to upgrade my version is:

curl -L "https://github.com/docker/compose/releases/download/1.13.0/docker-compose-$(uname -s)-$(uname -m)" > ./docker-compose sudo mv ./docker-compose /usr/bin/docker-compose sudo chmod +x /usr/bin/docker-compose 

Use the last version of docker compose instead of 1.13.0.
