如何在 spring 启动应用程序中公开 SPLUNK_ACCESS_TOKEN

Question

I have a spring boot application, in which I have imported the Splunk OTEL library(Splunk open telemetry jar file https://github.com/signalfx/splunk-otel-java ) for tracing and matrices. So a Splunk authentication token ie Splunk access token is needed to export data directly to Splunk Observability Cloud. Currently, I have exposed the Splunk access token in Kubernetes.yaml file as an env variable. But I don't want to expose this token by using Kubernetes.yaml or using a properties file. So I just want to know, is there any other way to expose or store the splunk_acces_token apart from Kubernetes.yaml or properties file?

For example: there is a flag variable "OTEL_JAVAAGENT_ENABLED" used by the Splunk OTEL library and I have stored this value to "true" in kubernetes.yaml file. So by this config OTEL jar is able to access it.

In these cases it's common for developers to use some type of key vault to encrypt keys and store small secrets like passwords.

Here's how I use Azure tooling to achieve this:

• Create an Azure Key Vault using Azure CLI
• Add accessToken secret and configure access to Azure Key Vault
• Use accessToken in your pipeline

This depends on the stack you're using, for example in AWS you could store the secret in AWS Secrets Manager and pass it to CodePipeline.
