vagrantのubuntu14.04(trusty)にDockerをインストールします。
まず、パッケージマネージャーをアップデートしておきます。
sudo apt-get update
そして、Dockerの最新を取得します。
wget -qO- https://get.docker.com/ | sh
文末にアラートが表示されるので、ユーザーをDockerグループに追加します。
If you would like to use Docker as a non-root user, you should now consider adding your user to the "docker" group with something like: sudo usermod -aG docker vagrant Remember that you will have to log out and back in for this to take effect! vagrant@vagrant-ubuntu-trusty-64:~$ sudo usermod -aG docker vagrant
では、Dockerが入っているか確認してみましょう。大丈夫そうですね。
vagrant@vagrant-ubuntu-trusty-64:~$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c04b14da8d14: Pull complete
Digest: sha256:0256e8a36e2070f7bf2d0b0763dbabdd67798512411de4cdcf9431a1feb60fd9
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
