MANDATORY: Always Use Backslashes on Windows for File Paths
When using Edit or Write tools on Windows, you MUST use backslashes (\) in file paths, NOT forward slashes (/).
Examples:
D:/repos/project/file.tsxD:\repos\project\file.tsxThis applies to:
NEVER create new documentation files unless explicitly requested by the user.
This skill covers the latest Docker features introduced in 2025, ensuring you leverage cutting-edge capabilities for security, performance, and developer experience.
What it is: Mount an image directory structure directly inside a container without extracting to a volume.
Key capabilities:
How to use:
# Mount entire image
docker run --rm \
--mount type=image,source=mydata:latest,target=/data \
alpine ls -la /data
# Mount specific path from image
docker run --rm \
--mount type=image,source=mydata:latest,image-subpath=/config,target=/app/config \
alpine cat /app/config/settings.json
Use cases:
What it is: Debug endpoints now accessible through standard versioned API paths.
Previously: Only available at root paths like /debug/vars
Now: Also accessible at /v1.48/debug/vars, /v1.48/debug/pprof/*
Available endpoints:
/v1.48/debug/vars - Runtime variables/v1.48/debug/pprof/ - Profiling index/v1.48/debug/pprof/cmdline - Command line/v1.48/debug/pprof/profile - CPU profile/v1.48/debug/pprof/trace - Execution trace/v1.48/debug/pprof/goroutine - Goroutine stacksHow to use:
# Access debug vars through versioned API
curl --unix-socket /var/run/docker.sock http://localhost/v1.48/debug/vars
# Get CPU profile
curl --unix-socket /var/run/docker.sock http://localhost/v1.48/debug/pprof/profile?seconds=30 > profile.out
Latest versions in Engine 28.3.3:

1. Faster Container Startup:
2. Better Resource Management:
3. Storage Driver Enhancements:
1. Enhanced Seccomp Profiles:
{
"defaultAction": "SCMP_ACT_ERRNO",
"architectures": ["SCMP_ARCH_X86_64", "SCMP_ARCH_AARCH64"],
"syscalls": [
{
"names": ["read", "write", "exit"],
"action": "SCMP_ACT_ALLOW"
}
]
}
2. Improved AppArmor Integration:
3. User Namespace Improvements:
What it is: Convert local compose.yaml files to Kubernetes manifests in a single command.
Key capabilities:
How to use:
# Convert compose file to Kubernetes manifests
docker compose convert --format kubernetes > k8s-manifests.yaml
# Or use compose-bridge directly
docker compose-bridge convert docker-compose.yml
# Apply to Kubernetes cluster
kubectl apply -f k8s-manifests.yaml
Example conversion:
# docker-compose.yml
services:
web:
image: nginx:latest
ports:
- "80:80"
volumes:
- data:/usr/share/nginx/html
volumes:
data:
# Converts to Kubernetes:
# - Deployment for 'web' service
# - Service exposing port 80
# - PersistentVolumeClaim for 'data'
Use cases:
1. Version Field Obsolete:
# OLD (deprecated):
version: '3.8'
services:
app:
image: nginx
# NEW (2025):
services:
app:
image: nginx
The version field is now ignored and can be omitted.
1. Develop Watch with initial_sync:
services:
app:
build: .
develop:
watch:
- action: sync
path: ./src
target: /app/src
initial_sync: full # NEW: Sync all files on start
2. Volume Type: Image:
services:
app:
volumes:
- type: image
source: mydata:latest
target: /data
read_only: true
3. Build Print:
# Debug complex build configurations
docker compose build --print > build-config.json
4. Config No-Env-Resolution:
# View raw config without environment variable substitution
docker compose config --no-env-resolution
5. Watch with Prune:
# Automatically prune unused resources during watch
docker compose watch --prune
6. Run with Quiet:
# Reduce output noise
docker compose run --quiet app npm test
1. Git SHA-256 Support:
# Use SHA-256 based repositories
ADD https://github.com/user/repo#sha256:abc123... /src
2. Enhanced COPY/ADD --exclude:
# Now generally available (was labs-only)
COPY --exclude=*.test.js --exclude=*.md . /app

ADD --unpack=true --chown=appuser:appgroup archive.tar.gz /app
4. Git Query Parameters:
# Fine-grained Git clone control
ADD https://github.com/user/repo.git?depth=1&branch=main /src
5. Image Checksum Verification:
# Verify image integrity
FROM alpine:3.19@sha256:abc123...
# BuildKit verifies checksum automatically
1. Improved Frontend Verification:
# Always use official Docker frontends
# syntax=docker/dockerfile:1
# Pin with digest for maximum security
# syntax=docker/dockerfile:1@sha256:ac85f380a63b13dfcefa89046420e1781752bab202122f8f50032edf31be0021

1. Backup existing configurations:
# Export current settings
docker context export desktop-linux > backup.tar
2. Update Docker Desktop:
3. Enable new features:
# Enable AI Assistant (beta)
docker desktop settings set enableAI=true
# Enable Enhanced Container Isolation
docker desktop settings set enhancedContainerIsolation=true
4. Test existing containers:
# Verify containers work with ECI
docker compose up -d
docker compose ps
docker compose logs
Before:
version: '3.8'
services:
app:
image: nginx:latest
volumes:
- data:/data
volumes:
data:
After:
services:
app:
image: nginx:1.26.0 # Specific version
volumes:
- data:/data
develop:
watch:
- action: sync
path: ./config
target: /etc/nginx/conf.d
initial_sync: full
volumes:
data:
driver: local
Problem: AI Assistant not responding Solution:
# Check Docker Desktop version
docker version
# Ensure beta features enabled
docker desktop settings get enableAI
# Restart Docker Desktop
Problem: Model Runner slow Solution:
Problem: Container fails with socket permission error Solution:
# Identify socket dependencies
docker inspect CONTAINER | grep -i socket
# If truly needed, add socket access explicitly
# (Document why in docker-compose.yml comments)
docker run -v /var/run/docker.sock:/var/run/docker.sock ...
Problem: ECI breaks CI/CD pipeline Solution:
docker desktop settings set enhancedContainerIsolation=falseProblem: "version field is obsolete" warning Solution:
# Simply remove the version field
# OLD:
version: '3.8'
services: ...
# NEW:
services: ...
Problem: watch with initial_sync fails Solution:
# Check file permissions
ls -la ./src
# Ensure paths are correct
docker compose config | grep -A 5 watch
# Verify sync target exists in container
docker compose exec app ls -la /app/src
