The Chromium resolver accepted any candidate that merely existed (command -v / -x), so it selected xfce's intentionally-disabled /usr/local/bin/chromium stub (exits 126 "Chromium is disabled, use google-chrome") over the working google-chrome. The later "Check chromium version" verify then failed rc=126. Latent on fresh hosts (depends on role ordering vs the stub install) and deterministic on any re-run. Now require `<candidate> --version` to succeed before accepting, so the stub is skipped and google-chrome is resolved. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> |

Playbook roles planning
This document clarifies what should live under /playbooks/roles/ for host-level automation (Ansible) versus what should be delivered through Helm charts, and ensures we cover the five tiers across data platforms: data warehouse → big data → ML → DL → large models.
Scope rules
- Ansible roles: host-coupled configuration that is not itself a cloud resource (GPU driver/runtime, OS tuning, user/SSH prep, rendering on-host config files, database bootstrapping, etc.).
- Helm charts: anything that runs as a Kubernetes workload (operators, clusters, services running in pods).
Base roles shared across tiers (Ansible)
- GPU driver and CUDA stack installation.
- Docker/Containerd runtime setup.
- System parameter tuning (kernel limits, hugepages, network stack), plus user home/SSH layout.
- Database initialization tasks (e.g., bootstrap PostgreSQL/ClickHouse on hosts) and rendering templated configs such as
ClickHouse/users.xml.
Coverage by capability tier
| Tier | Host-focused roles (Ansible) | Kubernetes services (Helm) |
|---|---|---|
| Data warehouse | ClickHouse host bootstrap & config render; PostgreSQL init where needed. | — |
| Big data | JVM/runtime, local disks, and OS tuning for data nodes. | Spark Operator; Flink Operator; Kafka/Redpanda; MinIO. |
| ML | GPU runtime base (drivers, container runtime), Python ML base image prep; user workspace/SSH. | Ray Cluster; MLflow; JupyterHub. |
| DL | Same GPU/system tuning plus inference node bootstrap (tensorRT/cuDNN as needed). | Triton Inference Server; LMDeploy (for deployment runtimes). |
| Large models | Secure SSH/user profiles and config templating for model storage/IO. | vLLM serving; model-specific Helm releases atop Ray/K8s. |
Suggested role layout under /playbooks/roles/
common/(new): shared tasks for system tuning, users/SSH, and package repos for GPU/runtime support.gpu/: install GPU drivers + CUDA toolkit.container_runtime/: install and configure Docker/Containerd with GPU runtime integration.database_init/: bootstrap on-host databases (e.g., PostgreSQL, ClickHouse), render config files (users.xml, etc.).bigdata_node_prep/: OS/disk tuning for Spark/Flink/Kafka/Redpanda/MinIO hosts.ml_node_prep/: Python/conda base, SSH workspace prep for ML workloads.dl_inference_node/: tensorRT/cuDNN dependencies and runtime checks for Triton/LMDeploy nodes.
Helm-delivered components should live under playbooks/roles/charts/ or the repo’s Helm release structure and include Spark/Flink Operators, Kafka/Redpanda/MinIO, Ray Cluster, Triton, vLLM/LMDeploy, MLflow, and JupyterHub.
