[GRDM-55309] RDM Providerにおけるハッシュ計算を .binder (binder) 構成ベースに対応

[yacchin1205]

RDM Providerにおけるハッシュ計算を .binder (binder) 構成ベースに対応します。 RCOSDP/CS-repo2docker#22 の変更を利用するようにします。

最新repo2docker(2025.10.0)はイメージ作成時はデータは取り込まず、Jupyter Server起動時に取り込む仕様に変更になりました。そのため、JupyterHubのSpawner設定では以下のコマンドで provision.shの取り込みを行う必要がある点に留意ください。

class Binder**Spawner(KubeSpawner):
...
    cmd = [
        'bash', '-c',
        """
set -e

# Find and execute provision.sh if it exists
for path in \
    "${REPO_DIR}/binder/provision.sh" \
    "${REPO_DIR}/.binder/provision.sh" \
    "$HOME/binder/provision.sh" \
    "$HOME/.binder/provision.sh"; do

    if [ -f "$path" ]; then
        echo "[provision-wrapper] Executing: $path" >&2
        exec bash "$path" "$@"
    fi
done

# No provision.sh found, start normally
exec "$@"
        """,
        '--', 'jupyterhub-singleuser'
    ]
...
