Vytváření různých prostředků pomocí Pulumi a Wrangler
Tento příklad vytváří zónu a další zdroje pomocí dvou různých strategií:
- Používejte Pulumi pro některé zdroje podporované poskytovatelem Cloudflare Pulumi.
- Pro vytváření dalších typů zdrojů použijte Wrangler.
Ukázkový kód pokrývá vytváření zdrojů, jako jsou Workers, Zero Trust Applications, Zero Trust Policies a databáze D1.
Použití Wrangler
Kód v tomto příkladu ukazuje, jak můžete vytvářet Workers přímým voláním Wrangler místo použití zdroje přímo podporovaného poskytovatelem Cloudflare Pulumi. Výhodou tohoto postupu je, že jej lze použít pro jakýkoli úkol související s nasazením, například spouštění migrací D1. Při spuštění skriptu infrastructure as code (IaC) Wrangler vytvoří nebo aktualizuje Workers a D1, což zahrnuje i provedení migrací databáze.
V aktuálním příkladu se stav migrací D1 v Pulumi změní pouze tehdy, když se změní hash migrations adresáře, v němž se příkaz Pulumi provede.
Dynamický poskytovatel prostředků pro Vectorize
Příklad také ukazuje dynamického poskytovatele zdrojů pro zdroj, který není přímo podporován poskytovatelem Cloudflare Pulumi (v tomto případě Vectorize).

Jakmile spustíte svůj skript Pulumi pomocí pulumi up, vaše prostředky budou vytvořeny nebo aktualizovány.
Výše uvedený ukázkový skript také exportuje výstupy, ke kterým můžete přistupovat z jiných nástrojů. To se hodí například při začleňování skriptu Pulumi do nasazovací pipeline.
Můžete použít příkaz podobný následujícímu:
pulumi stack output myServiceTokenClientSecret --show-secrets
