Safe what issues to your enterprise.
There’s loads to consider whereas working with containers, Kubernetes, cloud, and secrets and techniques. You must make use of and relate finest practices round id and entry administration and select and perform numerous instruments.
Whether or not you’re a developer or a sysadmin skilled, you want to clarify that you’ve the correct selection of instruments to maintain your environments safe. Functions want entry to configuration knowledge in place to function appropriately. And whereas most configuration knowledge is non-sensitive, some wants to stay confidential. These strings are often called secrets and techniques.

Don’t inform me you continue to have secrets and techniques in GitHub.
Effectively, Should you’re constructing a dependable utility, the possibilities are that your features require you to entry secrets and techniques or another sorts of delicate data you’re maintaining.
