安装OpenTelemetry Operator

OpenTelemetry Operator的部署，官方主要支持两种方式：yaml部署和helm部署

yaml部署

yaml部署较简单直接

# 安装cert-manager(依赖)
~ kubectl apply -f https://github.com/cert-manager/cert-manager/releases/latest/download/cert-manager.yaml
# 安装OpenTelemetry Operator
~ kubectl apply -f https://github.com/open-telemetry/opentelemetry-operator/releases/latest/download/opentelemetry-operator.yaml

helm部署

helm部署支持设置证书配置参数，可以不使用cert-manager，以及灵活配置更多参数

配置helm repo，下载helm chart

~ helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts
~ helm repo update
~ helm search repo open-telemetry/opentelemetry-operator --versions
~ helm pull open-telemetry/opentelemetry-operator --version 0.92.3 # 当前最新版本
~ tar -xf opentelemetry-operator-0.92.3.tgz

修改部分配置

主要修改image地址，资源配置，以及启用自动生成证书

values.yaml

...
admissionWebhooks:
...
certManager:
  enabled: false
