Jetson NanoでWordPressサーバー構築(Docker編)

Jetson Nano

こちらの方が、簡単にWordPressを起動できます。
理解するのは、勉強が必要ですが…

必要なパッケージのインストール

sudo無しでdockerコマンドを実行するために、dockerのグループに加わる。

$ sudo gpasswd -a $USER docker

必要なパッケージをインストールします。

$ sudo apt install -y python3 python3-pip
$ sudo pip3 install setuptools_rust

「docker-compose」をインストールするところで、エラーが発生。

$ sudo pip3 install docker-compose

    running build_rust

        =============================DEBUG ASSISTANCE=============================
        If you are seeing a compilation error please try the following steps to
        successfully install cryptography:
        1) Upgrade to the latest pip and try again. This will fix errors for most
           users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
        2) Read https://cryptography.io/en/latest/installation/ for specific
           instructions for your platform.
        3) Check our frequently asked questions for more information:
           https://cryptography.io/en/latest/faq/
        4) Ensure you have a recent Rust toolchain installed:
           https://cryptography.io/en/latest/installation/#rust

        Python: 3.6.9
        platform: Linux-4.9.299-tegra-aarch64-with-Ubuntu-18.04-bionic
        pip: 9.0.1
        setuptools: 59.6.0
        setuptools_rust: 1.1.2
        rustc: n/a

    error: can't find Rust compiler

    If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

    To update pip, run:

        pip install --upgrade pip

    and then retry package installation.

    If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

    This package requires Rust >=1.48.0.

以下のコマンドをしたら、インストールできました。

$ pip3 install --upgrade pip

dockerでWordPressの起動

『docker-compose.yml」ファイルを作成します。

$ nano docker-compose.yml

version: "3"

  mysql_container:
    image: mysql
    networks:
      - wp_net
    volumes:
      - ./db_data/:/var/lib/mysql

イメージを一斉に削除する方法

$ docker system prune -a
