This is a **breaking change** for users who rely on EKS integration without explicitly enabling it. + +**Affected Symbol:** `UseEKS` in `pkg/config/default.go:58` + +**PR:** [#1903 - Modernize Helmfile EKS integration](https://github.com/cloudposse/atmos/pull/1903) + +## Why EKS is Now Opt-In + +### Before (Legacy Behavior) + +Previously, `use_eks` defaulted to `true`, meaning: +- Atmos always attempted to update kubeconfig for EKS clusters before running helmfile commands +- Required AWS authentication even for non-EKS Kubernetes clusters +- Users of GKE, AKS, k3s, or local clusters had to explicitly disable EKS integration +- Caused confusion and failures when AWS credentials were not available + +```yaml +# Before: use_eks was true by default (implicit) +components: + helmfile: + base_path: "components/helmfile" + # use_eks: true # This was the implicit default +``` + +### After (New Behavior) + +Now, `use_eks` defaults to `false`: +- Atmos assumes you have a working kubeconfig and uses it directly +- EKS-specific authentication is opt-in +- Works immediately with any Kubernetes cluster (GKE, AKS, k3s, minikube, etc.) +- No AWS credentials required unless you explicitly enable EKS integration + +```yaml +# After: use_eks defaults to false +# You must explicitly enable it for EKS clusters +components: + helmfile: + base_path: "components/helmfile" + use_eks: true # Now required for EKS users +``` + +### Rationale + +1. **Broader Kubernetes Support**: Most helmfile users are not exclusively using EKS. The default should work for all Kubernetes clusters. + +2. **Principle of Least Surprise**: Requiring AWS credentials by default is surprising for users who just want to run `helmfile apply` with their existing kubeconfig. + +3. **Explicit Configuration**: EKS integration involves specific AWS API calls (`eks:DescribeCluster`, `eks:ListClusters`). This should be an explicit choice, not a hidden default. + +4. **Error Reduction**: Eliminated timeout errors and authentication failures for non-EKS users who didn't know they needed to disable EKS integration. + +## How to Restore Prior Behavior + +### Option 1: Explicit Configuration (Recommended) + +Add `use_eks: true` to your `atmos.yaml`: + +```yaml +components: + helmfile: + use_eks: true + kubeconfig_path: /dev/shm # Recommended for EKS + cluster_name_template: "{{ .vars.namespace }}-{{ .vars.environment }}-{{ .vars.stage }}-eks-cluster" +``` + +### Option 2: Environment Variable + +Set the environment variable before running Atmos commands: + +```bash +export ATMOS_COMPONENTS_HELMFILE_USE_EKS=true +atmos helmfile apply my-component -s prod +``` + +This is useful for CI/CD pipelines where you want to enable EKS integration without modifying configuration files. + +### Option 3: Per-Component Cluster Configuration + +Configure EKS cluster details at the component level using vars: + +```yaml +# stacks/prod.yaml +import: + - catalog/defaults + +vars: + stage: prod + +components: + helmfile: + my-component: + vars: + # Component-level cluster configuration + eks_cluster_name: "prod-eks-cluster" + eks_cluster_region: "us-west-2" +``` + +Note: The `use_eks` setting is configured globally in `atmos.yaml`. Per-component vars can provide cluster-specific details that are used by `cluster_name_template`. + +## Impact on Existing Configurations + +### Configurations That Will Break + +| Scenario | Before | After | Fix | +|----------|--------|-------|-----| +| EKS cluster, no explicit `use_eks` | Works (implicit true) | Fails (kubeconfig not updated) | Add `use_eks: true` | +| EKS with `helm_aws_profile_pattern` | Works | Deprecated warning, still works | Migrate to `--identity` flag | +| EKS with `cluster_name_pattern` | Works | Deprecated warning, still works | Migrate to `cluster_name_template` | + +### Configurations That Will Continue Working + +| Scenario | Notes | +|----------|-------| +| Explicit `use_eks: true` | No change needed | +| Non-EKS clusters (GKE, AKS, k3s) | Works better now (no EKS auth attempts) | +| Explicit `use_eks: false` | No change needed | +| Using `--identity` flag | Works with explicit `use_eks: true` | + +### Deprecation Warnings + +When using deprecated options, Atmos will log warnings but continue to work: + +```text +WARN: helm_aws_profile_pattern is deprecated.

What happened? + +A: If you were using EKS clusters without explicit `use_eks: true`, Atmos no longer updates your kubeconfig automatically. Add `use_eks: true` to your configuration. + +### Q: Do I need to change anything if I'm using GKE/AKS/k3s? + +A: No. The change actually improves your experience by not attempting EKS authentication. + +### Q: Can I still use `helm_aws_profile_pattern`? + +A: Yes, but it's deprecated and will log a warning. We recommend migrating to the `--identity` flag for AWS authentication. + +### Q: What's the difference between `cluster_name_pattern` and `cluster_name_template`? + +A: `cluster_name_pattern` uses simple token replacement (`{namespace}`), while `cluster_name_template` uses Go templates (`{{ .vars.namespace }}`). The template syntax is more powerful and consistent with stack configurations. + +### Q: Will the deprecated options be removed? + +A: Yes, `helm_aws_profile_pattern` and `cluster_name_pattern` will be removed in a future major release.
