Purbo dari Penerbit Andi. Informasi lebih lanjut mengenai buku ini: sampul, daftar isi, dan cara pembelian dapat dilihat pada tautan ini. 3 | 4 | Contoh ini menggunakan aplikasi demo yang didapat dari repositori [kudemo](https://github.com/ngoprek-kubernetes/kudemo) dengan image yang dipublish melalui docker registry [docker.io/ngoprek](https://hub.docker.com/u/ngoprek). 5 | 6 | # Catatan 7 | Jika pembaca menemukan kesalahan pada contoh, atau ada konfigurasi yang tidak jalan di Kubernetes pilihannya, silahkan raise pull request untuk perbaikan. Contoh-contoh ini telah dites pada [minikube](https://minikube.sigs.k8s.io/docs/start/), namun Kubernetes di provider lain bisa saja memerlukan konfigurasi spesifik yang berbeda, misalnya Ingress bawaan GKE (Google Kubernetes Engine). 8 | -------------------------------------------------------------------------------- /bab-07c-kudemo-api-deployment.yaml: -------------------------------------------------------------------------------- 1 | apiVersion: apps/v1 2 | kind: Deployment 3 | metadata: 4 | name: kudemo-api-deployment 5 | spec: 6 | replicas: 3 7 | selector: 8 | matchLabels: 9 | component: api 10 | template: 11 | metadata: 12 | labels: 13 | component: api 14 | spec: 15 | containers: 16 | -
