Nextcloud(podman)+MySQL

PodmanでNextcloud+ホストで稼働するMySQLを構築

podmanのネットワークの確認

# podman network ls
# podman network inspect podman | grep -e 'gateway' -e 'subnet'
   "gateway": "10.88.0.1",
   "subnet": "10.88.0.0/16"

MySQLの設定

インストールは、MySQL参照
アドレスは、podmanのネットワーク確認のsubnetを参考にセグメントを指定

# mysql -u root -p
CREATE DATABASE nextcloud CHARACTER SET utf8mb4;
CREATE USER 'hoge'@'10.88.0.%' IDENTIFIED BY '(パスワード)';
GRANT ALL PRIVILEGES ON nextcloud.* TO 'hoge'@'10.88.0.%';

nextcloudとDBの公式イメージを取得

# podman pull docker.io/library/nextcloud:latest

結果を確認

# podman images
REPOSITORY                   TAG         IMAGE ID      CREATED       SIZE
docker.io/library/nextcloud  latest      a4becf970bce  11 hours ago  909 MB

イメージの基本情報を確認

# podman inspect docker.io/library/nextcloud:latest

Pod を作成

# podman pod create -p 8080:80 --name nextcloud-pod

作業フォルダを作成

# mkdir /usr/local/nextcloud
# cd /usr/local/nextcloud
永続化用のフォルダ作成
# mkdir -p /usr/local/nextcloud/data/html
# mkdir -p /usr/local/nextcloud/data/log

コンテナ作成

# podman run --name=nextcloud -d --pod nextcloud-pod \
-d --restart=always \
-e MYSQL_DATABASE="nextcloud" \
-e MYSQL_USER="china" \
-e MYSQL_PASSWORD="sadaaki1" \
-e MYSQL_HOST="192.168.1.7" \
-v /usr/local/nextcloud/data/html:/var/www/html:Z \
-v /usr/local/nextcloud/data/log:/var/log/html:Z \
docker.io/library/nextcloud:latest

結果を確認

# podman ps

systemd のUNITファイルを生成＋常駐化

# systemctl stop pod-nextcloud-pod.service
# cd /etc/systemd/system
# podman generate systemd --restart-policy no -n -f nextcloud-pod
# systemctl daemon-reload
# systemctl enable pod-nextcloud-pod.service

サービスの起動・停止・ステータス

systemctl stop pod-nextcloud-pod.service
systemctl start pod-nextcloud-pod.service
systemctl status pod-nextcloud-pod.service

初期登録

http://192.168.1.7:8080

Kubernetesのyamlファイル作成

# cd /usr/local/nextcloud
# podman generate kube nextcloud-pod > nextcloud-pod.yaml

ポットレベルからの再作成準備（削除）

設定をまとめて削除

# systemctl stop pod-nextcloud-pod.service
# podman pod ls
# podman ps
# podman pod stop nextcloud-pod
# podman pod rm nextcloud-pod

イメージ削除

podman images
podman rmi nextcloud
