Day-25 - Understanding Service Accounts in Kubernetes

Day-25 - Understanding Service Accounts in Kubernetes

Today’s deep dive was all about understanding Service Accounts in Kubernetes

We often talk about users in Kubernetes — but did you know there are two types?
👤 Human Users – Engineers logging in for troubleshooting or cluster management.
🦾 Service Accounts – Automation identities used by applications, controllers, or CI/CD systems.

Think of Service Accounts as “non-human users” that allow tools like Jenkins, Prometheus, or Datadog to interact securely with the Kubernetes API 🔐

Key Learnings:
1) Service Accounts are namespace-scoped and created automatically for each namespace.
2) Tokens and certificates are mounted as secrets into pods at /var/run/secrets/https://lnkd.in/dSBGJkQs.
3) With RBAC roles and bindings, we can finely control what each Service Account can do.
4)They enable secure automation — no human credentials involved, just clean, auditable access.

 Best Practice:
Use Service Accounts for automation, follow the least privilege principle, and rotate tokens regularly.

This blog post is intended for those people that know VCD quite well and want to understand how is VCFA similar or different to help them quickly orient in the new direction. It should be emphasized that VCFA is a new solution and not just rebranding of an old one. However it reuses a lot of components from its predecessors. The provider part of VCFA called Tenenat Manager is based on VCD code and the UI and APIs will be familiar to VCD admins, while the tenant part inherist a lot from Aria Automation and especially for VCD end-users will look brand new. Deployment and Architecture VCFA is generaly deployed from VCF Operations Fleet Management (former Aria Suite LCM embeded in VCF Ops. Fleet Management...

  Issue with Aria Automation Custom form Multi Value Picker and Data Grid https://knowledge.broadcom.com/external/article?articleNumber=345960 Products VMware Aria Suite Issue/Introduction Symptoms: Getting  error " Expected Type String but was Object ", w hen trying to use Complex Types in MultiValue Picker on the Aria for Automation Custom Form. Environment VMware vRealize Automation 8.x Cause This issue has been identified where the problem appears when a single column Multi Value Picker or Data Grid is used. Resolution This is a known issue. There is a workaround.  Workaround: As a workaround, try adding one empty column in the Multivalue picker without filling the options. So we can add one more column without filling the value which will be hidden(there is a button in the designer page that will hide the column). This way the end user will receive the same view.
