Helm, Kubernetes üzerinde çalışan ilk uygulama paketi yöneticisidir. Uygulama yapısının uygun helm-charts aracılığıyla tanımlanmasına ve basit komutlarla yönetilmesine olanak tanır. Tüm Helm komutlarını (helm cheat sheet) yazının devamında inceleyebilirsiniz.
Helm neden önemlidir? Çünkü bu, sunucu tarafı uygulamaların tanımlanma, saklanma ve yönetilme biçiminde büyük bir değişimdir. Helm’in benimsenmesi, mikro hizmetlerin toplu olarak benimsenmesinin anahtarı olabilir, çünkü bu paket yöneticisini kullanmak yönetimlerini büyük ölçüde basitleştirir.
