1 - Configuration

VIBE supports enabling components on demand and exposes services via a unified workspace and Nginx portal.

Overview

Note: module default is jupyter_enabled: false, while conf/vibe.yml explicitly sets it to true.

Config usually lives in cluster vars, and can be overridden at instance level:

all:
  children:
    infra:
      hosts:
        10.10.10.10:
          vibe_data: /fs
          code_enabled: true
          jupyter_enabled: true
          claude_enabled: true

Workspace

vibe_data is the unified workspace for VIBE:

• Code-Server default open directory
• JupyterLab root_dir
• Claude Code working dir
• CLAUDE.md / AGENTS.md context files

The vibe_dir task creates the directory and context files, owned by node_user.

vibe_data: /fs

Code-Server

code_enabled: true
code_port: 8443
code_data: /data/code
code_password: Vibe.Coding
code_gallery: openvsx

Notes:

• Service listens on 127.0.0.1:<code_port> (default 8443), accessed via Nginx /code/
• Config file: code_data/code-server/config.yaml (default /data/code/code-server/config.yaml)
• Env file: /etc/default/code, used to configure extension marketplace

Extension marketplace:

• code_gallery: microsoft uses Microsoft marketplace
• When region=china, Open VSX defaults to Tsinghua mirror

JupyterLab

jupyter_enabled: true
jupyter_port: 8888
jupyter_data: /data/jupyter
jupyter_password: Vibe.Coding
jupyter_venv: /data/venv

Notes:

• Service listens on 0.0.0.0:<jupyter_port> (default 8888), base path /jupyter/
• Config file: jupyter_data/jupyter_config.py (default /data/jupyter/jupyter_config.py)
• Login token: c.IdentityProvider.token
• Venv is not created automatically, use node_uv_env in NODE module beforehand

Create venv example:

uv venv /data/venv

Node.js

nodejs_enabled: true
nodejs_registry: ''
npm_packages:
  - '@anthropic-ai/claude-code'
  - happy-coder

Notes:

• When nodejs_registry is empty and region=china, default registry is https://registry.npmmirror.com
• npm_packages are installed via npm install -g and available globally
• @anthropic-ai/claude-code is installed by default, so manual Claude CLI install is usually unnecessary

Claude Code

claude task only writes configuration (claude_config). By default, Claude CLI is installed by the nodejs task through npm_packages (including @anthropic-ai/claude-code).

claude_enabled: true
claude_env:
  ANTHROPIC_API_KEY: sk-ant-xxx

If nodejs_enabled is disabled or npm_packages is emptied, install Claude CLI manually.

Generated files:

• ~/.claude.json
• ~/.claude/settings.json

claude_env is merged with default OpenTelemetry env vars, sending telemetry to VictoriaMetrics / VictoriaLogs.

Nginx Portal

VIBE exposes services through infra_portal. By default, home domain includes /code/ and /jupyter/ paths.

For dedicated domains:

infra_portal:
  code: { domain: code.pigsty, endpoint: "127.0.0.1:8443", websocket: true }
  jupyter: { domain: jupyter.pigsty, endpoint: "127.0.0.1:8888", websocket: true }

• OTEL_EXPORTER_OTLP_LOGS_ENDPOINT=http://127.0.0.1:9428/insert/opentelemetry/v1/logs

3 - Playbook

VIBE module provides vibe.yml playbook to deploy Code-Server, JupyterLab, Node.js and Claude Code config.

vibe.yml includes only node_id and vibe roles, it does not include node/infra. Run deploy.yml first, or explicitly run node.yml and infra.yml.

vibe.yml

vibe.yml:

- name: VIBE
  hosts: all
  become: true
  gather_facts: no
  roles:
    - { role: node_id, tags: id }
    - { role: vibe,    tags: vibe }

4 - Administration

Service Management

systemctl status code-server
systemctl restart code-server
systemctl status jupyter
systemctl restart jupyter

Logs:

journalctl -u code-server -f
journalctl -u jupyter -f

Workspace and Context

vibe_dir creates these under vibe_data:

• CLAUDE.md
• AGENTS.md (symlink to CLAUDE.md)

Default locations (adjustable via vibe_data):

/fs/CLAUDE.md
/fs/AGENTS.md

Password and Auth

Code-Server

Edit config:

vi /data/code/code-server/config.yaml
systemctl restart code-server

Or via Ansible:

./vibe.yml -l <host> -e code_password='NewPassword' -t code_config,code_launch

JupyterLab

Config file: /data/jupyter/jupyter_config.py

Field: c.IdentityProvider.token

vi /data/jupyter/jupyter_config.py
systemctl restart jupyter

Code-Server Extensions

code-server --install-extension ms-python.python
code-server --list-extensions
code-server --uninstall-extension ms-python.python

Switch extension marketplace:

code_gallery: microsoft

Redeploy:

./vibe.yml -l <host> -t code_config,code_launch

JupyterLab Environment

VIBE does not create venv automatically, ensure jupyter_venv exists:

uv venv /data/venv

Install/upgrade JupyterLab:

uv pip install --python /data/venv/bin/python jupyterlab ipykernel
systemctl restart jupyter

Install extensions (in venv):

source /data/venv/bin/activate
pip install jupyterlab-git
systemctl restart jupyter

Claude Code

The claude_config subtask only writes config files. Claude CLI is installed globally by nodejs_pkg through npm_packages (which includes @anthropic-ai/claude-code by default).

which claude
claude --version

Config files:

• ~/.claude.json
• ~/.claude/settings.json

Update config:

./vibe.yml -l <host> -t claude_config

Reinstall/install Claude CLI:

./vibe.yml -l <host> -t nodejs_pkg
# or install manually
npm install -g @anthropic-ai/claude-code

To configure for another user, run as that user or copy the files manually.

File Locations

Troubleshooting

Port checks:

ss -tlnp | grep 8443
ss -tlnp | grep 8888

Nginx entry:

nginx -t
systemctl status nginx

5 - Monitoring

VIBE monitoring mainly focuses on Claude Code OpenTelemetry data. Code-Server and JupyterLab do not expose Prometheus metrics; use systemd and logs for health checks.

Claude Code Observability

VIBE writes default OpenTelemetry env vars into ~/.claude/settings.json:

{
  "env": {
    "CLAUDE_CODE_ENABLE_TELEMETRY": 1,
    "CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS": 1,
    "OTEL_LOG_USER_PROMPTS": 1,
    "OTEL_METRICS_EXPORTER": "otlp",
    "OTEL_LOGS_EXPORTER": "otlp",
    "OTEL_EXPORTER_OTLP_PROTOCOL": "http/protobuf",
    "OTEL_EXPORTER_OTLP_METRICS_ENDPOINT": "http://127.0.0.1:8428/opentelemetry/v1/metrics",
    "OTEL_EXPORTER_OTLP_LOGS_ENDPOINT": "http://127.0.0.1:9428/insert/opentelemetry/v1/logs",
    "OTEL_RESOURCE_ATTRIBUTES": "ip=<host>,job=claude"
  }
}

claude_env is merged with the defaults, and can be used for API keys or custom endpoints.

Grafana Dashboard

Grafana includes claude-code dashboard by default:

• Portal: https://<domain>/ui/d/claude-code
• Direct: http://<ip>:3000/d/claude-code

Runtime Checks

systemctl status code-server
systemctl status jupyter
journalctl -u code-server -f
journalctl -u jupyter -f

Port checks:

ss -tlnp | grep 8443
ss -tlnp | grep 8888

Claude Logs Query

Via VictoriaLogs:

curl -G 'http://127.0.0.1:9428/select/logsql/query' \
  --data-urlencode 'query=job:claude'

6 - FAQ

Deployment

code-server package not found

Ensure NODE and repo config are in place:

yum repolist    # EL
apt update      # Debian/Ubuntu
./infra.yml -t repo

JupyterLab installation failed

jupyter_venv must exist:

uv venv /data/venv
./vibe.yml -l <host> -t jupyter

Access

Cannot access /code/ or /jupyter/

1. Check service status
2. Check port listening
3. Check Nginx config

systemctl status code-server
systemctl status jupyter
ss -tlnp | grep 8443
ss -tlnp | grep 8888
nginx -t

WebSocket connection fails

Ensure Nginx enables WebSocket (default is enabled). If using custom infra_portal, set websocket: true.

Password and Token

Change Code-Server password

./vibe.yml -l <host> -e code_password='NewPass' -t code_config,code_launch

Change JupyterLab token

./vibe.yml -l <host> -e jupyter_password='NewToken' -t jupyter_config,jupyter_launch

Claude Code

CLI not found

First check whether nodejs_pkg completed (@anthropic-ai/claude-code is installed by default):

which claude
npm list -g --depth=0 | grep '@anthropic-ai/claude-code'
./vibe.yml -l <host> -t nodejs_pkg

If nodejs_enabled is disabled or npm_packages is overridden, install manually:

npm install -g @anthropic-ai/claude-code

API key not set

export ANTHROPIC_API_KEY=sk-ant-xxx
# or set in claude_env

Telemetry not showing

Check local VictoriaMetrics/VictoriaLogs:

curl http://127.0.0.1:8428/api/v1/status/buildinfo
curl http://127.0.0.1:9428/select/logsql/stats_query

Ensure OTEL endpoints in ~/.claude/settings.json are correct.

Extensions and Plugins

Code-Server extension install fails

• Check network
• Try switching code_gallery
• Or install VSIX manually

code-server --install-extension /path/to/extension.vsix

JupyterLab extension install fails

source /data/venv/bin/activate
pip install jupyterlab-git
systemctl restart jupyter
