#dockerfile

  • Alpine JVM
    A Java/Spring Boot Dockerfile on Alpine JRE with JVM tuning, graceful shutdown, a curl healthcheck, and OCI labels, balancing image size against maintainability.
  • Auto Dependency
    A Java Dockerfile that automatically upgrades Gradle plugins and dependencies at build time and uses a compiled Java class as the healthcheck on a distroless runtime.
  • Distroless JLink
    A Java Dockerfile that builds a minimal custom JRE with jlink and jdeps and runs it on a distroless base image with a busybox wget healthcheck.
  • Optimization Techniques
    An overview of four Dockerfile optimization approaches for Java/Spring Boot applications, compared by image size, security, and performance.
  • Ultra Optimized
    The most heavily optimized Java Dockerfile, combining a hand-picked jlink JRE, Spring Boot layered JARs, tini, SHA256-pinned Alpine, and a non-root CIS-compliant user.
  • Alpine Optimized
    A Python FastAPI Dockerfile on Alpine that strips libraries, bytecode, and unused stdlib modules to get an image under 110MB with a non-root user.
  • Optimization Techniques
    An index of Dockerfile optimization approaches for Python applications, comparing distroless, Alpine, wheel-based offline, and UV plus tini builds.
  • UV Alpine Tini
    A simple, maintainable Python Dockerfile using UV on Alpine with tini as init, plus a cross-Dockerfile comparison, best practices, and conclusion for the Python series.
  • UV Distroless
    A multi-arch Python Dockerfile that installs dependencies with UV and runs on a distroless Debian 12 base with manually copied shared libraries for high security and small size.
  • Wheel Offline
    A Python Dockerfile that builds all dependencies into wheels in a builder stage, auto-patches vulnerable versions, and installs them offline in a slim runtime.
