Environment variable way using Secret example analysis, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Using Secret with Volume, the container must read data from a file, which can be a bit of a hassle, and Kubernetes also supports the use of Secret through environment variables.

An example of a Pod configuration file is as follows:

Create the Pod and read the Secret.

The data of Secret is successfully read through the environment variables SECRET_USERNAME and SECRET_PASSWORD.

It is important to note that it is convenient for environment variables to read Secret, but it does not support Secret dynamic updates.

Secret can provide Pod with sensitive data such as password, Token, private key, etc., and ConfigMap can be used for some non-sensitive data, such as application configuration information.

After reading the above, have you mastered the method of analyzing environment variables using Secret's example? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
