Ubuntu 和更新 Docker

Question

我正在尝试运行最新稳定版本的 docker 和 docker-compose。

我按照 https://docs.docker.com/engine/installation/linux/ubuntulinux/ 上的说明进行操作

显然 docker-compose 的当前版本是 1.7。

然而，在运行文档，安装 docker-engine 之后，我得到:

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

和

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

当我尝试更新它时，我得到以下信息:

$ 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

更新

这只是越来越陌生。在尝试了以下所有建议后，我现在明白了:

$ 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.

那么我该如何更新 docker？

Answer 1

由于我在这方面浪费了半个小时，也许它会对那里的一些人有所帮助。我必须做的升级我的版本是:

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

使用 the last version of docker compose而不是 1.13.0.
