概要
TinkerBoardもTinkerOS 2.0.3(Beta)にて、docker対応とのことで、インストールと簡単なテスト。
# リリースノートの > 22. Enable Docker support.
-
(追記) docker-compose の導入
linaro@tinkerboard:~/compose$ docker-compose version docker-compose version 1.17.0-rc1, build 2a0dd14 docker-py version: 2.5.1 CPython version: 2.7.13 OpenSSL version: OpenSSL 1.0.1t 3 May 2016 linaro@tinkerboard:~/compose$
環境
- ASUS Tinker Board
TinkerOS V2.0.3(Beta) - 20170928-tinker-board-linaro-stretch-alip-v2.0.3.img.zip
microSD 16GB (UHS-I とかの速いのがいい。読み書き50MB/secくらいでるやつとか？)
手順
TinkerOS 2.0.3(beta)をmicroSDを焼いて、起動して、適当に初期設定を済ませる。
いつものツールで、いつも通りに。-

WARNING: Adding a user to the "docker" group will grant the ability to run containers which can be used to obtain root privileges on the docker host.

sudo docker run arm32v7/hello-world実行例linaro@tinkerboard:~$ sudo docker run arm32v7/hello-world Unable to find image 'arm32v7/hello-world:latest' locally latest: Pulling from arm32v7/hello-world e70c9dbed03f: Pull complete Digest: sha256:2e1917f5e14207289d534382d91834610860d3616dfd36406625f76ff20394fc Status: Downloaded newer image for arm32v7/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 Share images, automate workflows, and more with a free Docker ID: https://cloud.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/ linaro@tinkerboard:~$ -
