Dockerを使う練習をしてみようとした。 Sonic PIをインストールすることはできたが、 スーパバイザ側の画面にアプリを起動するまでは至らず。

参考

手順

以下のようなコマンドを実行したと思う。

# Install Docker
sudo dnf install docker
sudo systemctl start docker

% sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
Trying to pull repository docker.io/library/hello-world ... latest: Pulling from library/hello-world

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 Hub account:

Usage of loopback devices is strongly discouraged for production use. Either use `--storage-opt dm.thinpooldev` or use `--storage-opt dm.no_warn_on_loop_devices=true` to suppress this warning.

Fedora上でUbuntuを起動して、apt-getを使ったりできたので、とりあえず満足。 謎アプリケーションを入れるときのsandboxとかにも使えそう。
