Common Mistakes to Avoid
These pitfalls appear repeatedly when teams adopt deployment tools without aligning workflows, governance, and operational ownership to the tool's strengths.
Treating Kubernetes orchestration as plug and play without day two operations planning
Kubernetes requires expertise in debugging, observability, and upgrades, and misconfigured resource requests and limits can destabilize workloads. Argo CD reduces some rollout complexity by using health aware reconciliation, but day two cluster operations still need strong operational practices.
Building complex declarative change flows without a reliable state workflow
Terraform state drift and locking complexity can complicate team operations when state workflows and collaboration are not designed upfront. Kubernetes operators and autoscaling also depend on correct resource modeling, so unclear dependency and ordering design can create operational surprises.
Overlooking governance gaps in CI and CD pipeline promotions
GitHub Actions can accumulate complex workflow graphs that slow debugging when conventions do not limit sprawl. Azure DevOps includes environment approvals and checks, which helps enforce controlled promotion even when pipeline complexity grows.
Using Helm for infrastructure provisioning instead of Kubernetes application packaging
Helm deploys Kubernetes application charts, and it does not deploy non Kubernetes infrastructure without external orchestration. Teams needing infrastructure provisioning should use Terraform, AWS CloudFormation, or Google Cloud Deployment Manager for declarative infrastructure stacks.
