Docker Secrets Detection

Scan Docker configuration files for exposed secrets, credentials, and sensitive data.

File Scanning Targets

File	Risk Level	Common Secrets
`Dockerfile`	High	ARG/ENV with passwords, inline credentials
`docker-compose*.yml`	High	Environment variables, volume-mounted secrets
`.env`, `.env.*`	Critical	Database passwords, API keys, tokens
`entrypoint.sh`	Medium	Hardcoded credentials in scripts

Detection Patterns

1. Hardcoded Passwords

# CRITICAL: Password in Dockerfile (persists in image layers)
ENV MYSQL_ROOT_PASSWORD=SuperSecret123
ARG ADMIN_PASSWORD=admin123

# CRITICAL: Password in docker-compose.yml
services:
  database:
    environment:
      POSTGRES_PASSWORD: my_secret_password

2. API Keys and Tokens

# CRITICAL: API keys in build args
ARG GITHUB_TOKEN=ghp_ABCDEFghijklmnop1234567890
ENV STRIPE_SECRET_KEY=sk_live_xxxxxxxxxxxxxxxxxxxx
ENV AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

3. Private Keys and Certificates

# CRITICAL: Private key copied into image
COPY id_rsa /root/.ssh/id_rsa
COPY server.key /etc/ssl/private/server.key
ENV PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----\nMIIE..."

4. Database Connection Strings

# CRITICAL: Full connection string with credentials
ENV DATABASE_URL="postgresql://admin:secret@db:5432/myapp"
ENV REDIS_URL="redis://:password@redis:6379/0"

5. Default and Weak Passwords

# HIGH: Default/weak passwords in compose
services:
  database:
    environment:
      POSTGRES_PASSWORD: postgres
      MYSQL_ROOT_PASSWORD: root

Grep Patterns

# Passwords in Docker files
Grep: "(PASSWORD|PASSWD|PASS)\s*[:=]\s*['\"]?[a-zA-Z0-9!@#$%^&*()_+]{4,}" --glob "**/Dockerfile*" --glob "**/docker-compose*.yml" --glob "**/.env*"

# API keys and tokens
Grep: "(API_KEY|API_SECRET|ACCESS_KEY|SECRET_KEY|AUTH_TOKEN)\s*[:=]\s*['\"]?[a-zA-Z0-9_\-]{10,}" --glob "**/Dockerfile*" --glob "**/.env*"

# GitHub token pattern
Grep: "ghp_[a-zA-Z0-9]{36}" --glob "**/Dockerfile*" --glob "**/.env*"

# AWS key pattern
Grep: "AKIA[0-9A-Z]{16}" --glob "**/Dockerfile*" --glob "**/.env*"

# Private keys
Grep: "PRIVATE.KEY|BEGIN RSA|BEGIN EC|BEGIN OPENSSH" --glob "**/Dockerfile*"
Grep: "COPY.*(\.pem|\.key|id_rsa|id_ed25519)" --glob "**/Dockerfile*"

# Connection strings with credentials
Grep: "(mysql|postgres|postgresql|mongodb|redis)://[^:]+:[^@]+@" --glob "**/Dockerfile*" --glob "**/.env*"

# Default passwords
Grep: "(PASSWORD|PASSWD)\s*[:=]\s*['\"]?(password|root|admin|secret|123456)['\"]?" -i --glob "**/docker-compose*.yml" --glob "**/.env*"

# Credentials in entrypoint scripts
Grep: "(-p['\"][^'\"]+['\"]|--password[= ]['\"]?[a-zA-Z0-9])" --glob "**/entrypoint*.sh"

False Positive Handling

Pattern	Why It’s False Positive	How to Handle
`PASSWORD=${DB_PASSWORD}`	Variable reference, not value	Skip if value is `${}` or `$()`
`password: ""`	Empty placeholder	Skip empty values
`# ENV PASSWORD=xxx`	Commented out	Skip lines starting with `#`
`PASSWORD_FILE=/run/secrets/db`	Docker secret file reference	Skip `*_FILE` suffixes
`.env.example`	Template file	Skip `.example` suffix

Remediation Patterns

Docker Compose Secrets

services:
  php-fpm:
    secrets: [db_password, api_key]
    environment:
      DB_PASSWORD_FILE: /run/secrets/db_password
secrets:
  db_password:
    file: ./secrets/db_password.txt
  api_key:
    external: true

BuildKit Build Secrets

RUN --mount=type=secret,id=composer_auth,target=/root/.composer/auth.json \
    composer install --no-dev
# Usage: docker build --secret id=composer_auth,src=auth.json .

Severity Classification

Pattern	Severity	Risk
Hardcoded password in Dockerfile	Critical	Persists in all image layers
Private key copied to image	Critical	Full authentication compromise
API key in environment variable	Critical	Service access compromise
Connection string with credentials	Critical	Database access compromise
Default/weak password	High	Easily guessable credentials
Password in docker-compose.yml	High	Exposed in version control
Credential in entrypoint script	Medium	Visible in container filesystem

Output Format

### Secret Detected: [Type]

**Severity:** Critical/High/Medium
**File:** `<file_path>:<line>`
**Type:** Password / API Key / Token / Private Key / Connection String

**Detection:**

// Matched pattern (redacted)


**Risk:**
[What could be compromised with this secret]

**Remediation:**
```yaml
// Secure alternative using Docker secrets or env_file

Verification Checklist:

Secret removed from file
File added to .gitignore if needed
Git history cleaned if secret was committed
Secret rotated (old value is compromised)
