P2 Badge Grant create before keeping the bootstrap branch

This kubeconfig is now sourced from the Vault-issued least-privilege token, but the deploy script still treats a missing supporttools-${ENVIRONMENT} Application as recoverable by piping argocd/${ENVIRONMENT}.yaml into kubectl apply below. The new role is scoped for the existing get/patch path, so if one of the six Applications is deleted or a cluster is rebuilt, this branch now fails with an RBAC error instead of recreating it as the old kubeconfig did; the same pattern exists in Deploy-Prod. Either give the token create on those Applications or replace the branch with a clear precondition failure.

Useful? React with 👍 / 👎.

P2 Badge Grant create before keeping the bootstrap branch
This kubeconfig is now sourced from the Vault-issued least-privilege token, but the deploy script still treats a missing supporttools-${ENVIRONMENT} Application as recoverable by piping argocd/${ENVIRONMENT}.yaml into kubectl apply below. The new role is scoped for the existing get/patch path, so if one of the six Applications is deleted or a cluster is rebuilt, this branch now fails with an RBAC error instead of recreating it as the old kubeconfig did; the same pattern exists in Deploy-Prod. Either give the token create on those Applications or replace the branch with a clear precondition failure.

P2 Badge Grant create before keeping the bootstrap branch
This kubeconfig is now sourced from the Vault-issued least-privilege token, but the deploy script still treats a missing supporttools-${ENVIRONMENT} Application as recoverable by piping argocd/${ENVIRONMENT}.yaml into kubectl apply below. The new role is scoped for the existing get/patch path, so if one of the six Applications is deleted or a cluster is rebuilt, this branch now fails with an RBAC error instead of recreating it as the old kubeconfig did; the same pattern exists in Deploy-Prod. Either give the token create on those Applications or replace the branch with a clear precondition failure.
Useful? React with 👍 / 👎.
