Ubuntu和更新Docker
我正在尝试运行docker和docker-compose的最新稳定版本。
我正在按照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。
但是,在阅读了文档并安装docker-engine之后,我得到了:
$ docker-compose --versiondocker-compose version: 1.4.0
和
$ docker --versionDocker version 1.11.1, build 5604cbe
当我尝试更新它时,得到以下信息:
$ sudo apt-get upgrade docker-engineReading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... docker-engine is already the newest version.
Done
这只会变得越来越陌生。在尝试了以下所有建议之后,我现在得到了:
$ docker-compose -vThe 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.
那我该如何更新Docker?
回答:
试试这个东西:
sudo sh -c "wget -qO- https://get.docker.io/gpg | apt-key add -"sudo sh -c "echo deb http://get.docker.io/ubuntu docker main\ > /etc/apt/sources.list.d/docker.list"
sudo aptitude update
sudo aptitude install lxc-docker
如果这不起作用,请通过第三方进行:
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9$ sudo sh -c "echo deb https://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
$ sudo apt-get update
$ sudo apt-get install lxc-docker
