ローカル環境でwordpressをセットアップする-DigitalOceanのkubernetes環境にwordpressを構築する02

2024年1月8日2024年1月14日

DOKSの手順のwordpressではなくwordpressのdockerイメージから作ります。

ローカルで作業します

download & run

docker pull wordpress:latest
docker run -p 80:80 -d -i docker.io/library/wordpress:latest

http://localhost/
に繋いでwordpressをセットアップします。

DBはGCEを指定しています。

ingress-nginx利用時にHTTPSで管理画面に接続できなくなるので(loopする)下記のプラグインを入れて有効化しておきます。

ssl-insecure-content-fixer

設定

有効
- HTTP_X_FORWARDED_PROTO (ロードバランサー、リバースプロキシ、NginX など)

イメージ化の準備

勝手に/var/www/htmlが永続ボリュームとしてマウントされているので、特定します

ocarina@ab350-pro4:~/work/wordpress.docker$ docker ps -a --format "{{.Names}}" | xargs docker inspect | jq -r '["Name","Type","Src","Dst"], (.[] | { Name:.Name, Mounts:.Mounts[] } | [ .Name, .Mounts.Type, .Mounts.Source, .Mounts.Destination ]) | @csv' 
"Name","Type","Src","Dst"
"/suspicious_wu","volume","/var/lib/docker/volumes/929d3a1a7386474b2e4103a37bf8e9d10cda628c05c2e4686c18c0104c9cdbc7/_data","/var/www/html"

カスタムイメージの準備

mkdir -p ~/work/wordpress.docker
cd ~/work/wordpress.docker
mkdir files
docker exec -it f0cc416da81a cat /etc/apache2/sites-enabled/000-default.conf > files/000-default.conf
sudo cp -rip /var/lib/docker/volumes/929d3a1a7386474b2e4103a37bf8e9d10cda628c05c2e4686c18c0104c9cdbc7/_data files/html

vi files/html/wp-config.php

/* Sets up WordPress vars and included files. /

// 複数ドメイン対応
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
// https強制の場合は下記アンコメント
//$protocol = "https://";

define('WP_HOME', $protocol . $_SERVER['HTTP_HOST']  );
define('WP_SITEURL', WP_HOME );

Dockerfile作成に当り公式wordpressのCMDを確認します

docker image inspect 9071407ed1c0 | jq ".[0]" | less

    "Env": [
      "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",

    "Cmd": [

とりあえずCMDだけ利用します。
