Secure Config and Encrypt Secrets on OpenShift with Vault. Read the ephemeral database credential from Vault (this creates a “temporary” user in MySQL): Since this is a “leased” secret from Vault, it must renew its lease from time to time. Some secrets engines simply store and read data, like the kv secrets engines or the cubbyhole (which is a specialized, ephemeral kv store, whose lifetime is based on invoking the token’s TTL). This is particularly important when working with Kubernetes, as Docker images are used to run applications. You can use these secrets as environment variables inside pod. With Pipeline, we provision large, multi-tenant Kubernetes clusters on all major cloud providers, such as AWS, GCP, Azure and BYOC, and deploy all kinds of predefined or ad-hoc workloads to these clusters. A lot of people suggest that GitOps is the way forward for doing CICD pipelines opposed to setting things up via kubectl, however I come to a stumbling block on how you would manage secrets in this pipeline. This has great security benefits, because it not only means that no-one actually needs to know passwords and other secrets as they only exist when they are required, but also it encourages applications and systems to expect secrets to become invalid at some point (expire).
