How to Configure Redis Password in Springboot 2.7.18 Kubernetes Deployment?

Method 1: Using Environment Variables:

Add the Redis password to the environment variables of the Pod. For example, using Helm:

<code>helm upgrade --set redis.master.password=my_password release-name</code>

Method 2: Using ConfigMaps:

Create a Kubernetes ConfigMap with the name of the Redis password:

<code>kubectl create configmap redis-config --from-literal=password=my_password</code>

Then, use the ConfigMap in the Springboot Pod to retrieve the password:

<code>spring:
  redis:
    password: ${REDIS_PASSWORD:my_password}</code>

Method 3: Using Kubernetes Secrets:

Create a Kubernetes Secret named redis-secret with a key-value pair of password and the Redis password:

<code>kubectl create secret generic redis-secret --from-literal=password=my_password</code>

Then, use the Secret in the Springboot Pod to retrieve the password:

<code>spring:
  redis:
    password: ${REDIS_SECRET:redis-secret:password}</code>

Method for Providing Redis Password to Springboot 2.7.18 Pod on Kubernetes

The common method used to provide the Redis password to Springboot 2.7.18 Pod on Kubernetes are:

• Using environment variables
• Using Kubernetes ConfigMaps
• Using Kubernetes Secrets

Using Kubernetes Secrets to Securely Store and Manage Redis Password for Springboot 2.7.18 Deployment

Kubernetes Secrets are one of the best methods to securely store and manage Redis passwords for Springboot 2.7.18 deployments. They provide several advantages:

• Centralized Management: Secrets can be created and managed centrally without changing Pod configurations.
• Improved Security: Secrets are stored in encrypted form, ensuring that passwords are protected.
• Version Control: Secrets can be versioned, allowing for easy retrieval in case of accidental deletion or changes.
• Integration with Pod: Secrets can be easily mounted into Pods, providing a secure way to access sensitive information.
