chef config set host example.com chef config set port 8080

3. Start service

chef start

4. Check status

chef status

5. Perform operations

chef run --target example.com

6. View results

chef results

7. Stop service

chef stop ```_

Advanced Workflow

```bash

Comprehensive operation with monitoring

chef run \ --config production.yaml \ --parallel \ --workers 8 \ --verbose \ --timeout 300 \ --output json \ --log-file operation.log

Automation Beispiel

```bash

!/bin/bash

Automated chef workflow

Configuration

TARGETS_FILE="targets.txt" RESULTS_DIR="results/$(date +%Y-%m-%d)" CONFIG_FILE="automation.yaml"

Create results directory

mkdir -p "$RESULTS_DIR"

Process each target

while IFS= read -r target; do echo "Processing $target..."

chef \
    --config "$CONFIG_FILE" \
    --output json \
    --output-file "$RESULTS_DIR/$\\\\{target\\\\}.json" \
    run "$target"

done < "$TARGETS_FILE"

Generate summary report

chef report summary \ --input "\(RESULTS_DIR/*.json" \ --output "\)RESULTS_DIR/summary.html" ```_
