Beispiele

Basis-Workflow

```bash

1. Initialize composer

composer init

2. Configure basic settings

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

3. Start service

composer start

4. Check status

composer status

5. Perform operations

composer run --target example.com

6. View results

composer results

7. Stop service

composer stop ```_

Advanced Workflow

```bash

Comprehensive operation with monitoring

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

Monitor in real-time

composer monitor --real-time --interval 5

Generate report

composer report --type comprehensive --output report.html ```_

Automation Beispiel

```bash

!/bin/bash

Automated composer 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..."

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

done < "$TARGETS_FILE"

Generate summary report

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