1、将helm项目导出为独立yaml文件-实践

1.1、需求

有时候，我们需要导出yaml分析yaml编写情况，而不是直接部署到k8s，这个时候，就需要使用template来实现了

1.2、开始操作

1.2.1、创建存放yaml文件的目录

helm_prometheus]# cd /opt/helm_prometheus/ && mkdir prometheus-tpl
helm_prometheus]# ll

drwxr-xr-x 5 root root 202 Apr 16 00:04 prometheus # 这个是项目目录
drwxr-xr-x 2 root root   6 Apr 16 00:24 prometheus-tpl # 这个是渲染出来的，存放yaml的目录

1.2.2、开始渲染

# 注意：一定要在项目目录的上一级目录执行。
helm_prometheus]# helm template prometheus --output-dir prometheus-tpl/
wrote prometheus-tpl//prometheus/charts/alertmanager/templates/serviceaccount.yaml
wrote prometheus-tpl//prometheus/charts/kube-state-metrics/templates/serviceaccount.yaml
wrote prometheus-tpl//prometheus/charts/prometheus-node-exporter/templates/serviceaccount.yaml
wrote prometheus-tpl//prometheus/charts/prometheus-pushgateway/templates/serviceaccount.yaml
wrote prometheus-tpl//prometheus/templates/serviceaccount.yaml
wrote prometheus-tpl//prometheus/charts/alertmanager/templates/configmap.yaml
wrote prometheus-tpl//prometheus/templates/cm.yaml
wrote prometheus-tpl//prometheus/templates/pvc.yaml
wrote prometheus-tpl//prometheus/charts/kube-state-metrics/templates/role.yaml
wrote prometheus-tpl//prometheus/templates/clusterrole.yaml
wrote prometheus-tpl//prometheus/charts/kube-state-metrics/templates/clusterrolebinding.yaml
wrote prometheus-tpl//prometheus/templates/clusterrolebinding.yaml
wrote prometheus-tpl//prometheus/charts/alertmanager/templates/services.yaml
wrote prometheus-tpl//prometheus/charts/alertmanager/templates/services.yaml
wrote prometheus-tpl//prometheus/charts/kube-state-metrics/templates/service.yaml
wrote prometheus-tpl//prometheus/charts/prometheus-node-exporter/templates/service.yaml
wrote prometheus-tpl//prometheus/charts/prometheus-pushgateway/templates/service.yaml
wrote prometheus-tpl//prometheus/templates/service.yaml
wrote prometheus-tpl//prometheus/charts/prometheus-node-exporter/templates/daemonset.yaml
wrote prometheus-tpl//prometheus/charts/kube-state-metrics/templates/deployment.yaml
wrote prometheus-tpl//prometheus/charts/prometheus-pushgateway/templates/deployment.yaml
wrote prometheus-tpl//prometheus/templates/deploy.yaml
wrote prometheus-tpl//prometheus/charts/alertmanager/templates/statefulset.yaml
wrote prometheus-tpl//prometheus/charts/alertmanager/templates/ingress.yaml
wrote prometheus-tpl//prometheus/templates/ingress.yaml
wrote prometheus-tpl//prometheus/charts/alertmanager/templates/tests/test-connection.yaml

1.2.3、查询渲染后的目录

helm_prometheus]# tree prometheus-tpl/
