4-4: 좋은 개선사항입니다!APT 캐시 정리(
rm -rf /var/lib/apt/lists/*)를 추가하여 최종 이미지 크기를 줄이는 것은 Docker 베스트 프랙티스입니다. 이미 단일RUN명령어로 최적화되어 있어 레이어 수도 최소화되었습니다.

eclipse-temurin:17 jdk focal slim image size comparison security 2025
💡 Result:
Summary (as of Dec 29, 2025)
-
Size (examples for amd64):
- eclipse-temurin:17-jdk-focal ≈ 417 MB (full JDK). [1][2]
- eclipse-temurin:17-jre-focal ≈ 266 MB (runtime/JRE). [2]
- Alpine variants (e.g., 17-jre-alpine) are much smaller (~50–80 MB compressed) but use musl and can break some apps. [1]
-
Security / CVEs:
- Focal-based Temurin images inherit Ubuntu 20.04 packages; vulnerability reports exist for focal images (example: CVE-2025-6965 reported for an image built on focal via Snyk). Keep packages updated or use ESM backports where required. [3]
- Eclipse Temurin images are maintained by Adoptium and receive Java security updates; you must still track OS-package CVEs in the base (focal) layer. [1]
-
Recommendations
- For minimal image size: use an Alpine Temurin JRE if your app and native dependencies are compatible. [1]
- For better compatibility and fewer package CVEs: use the focal/jammy JRE image (smaller than JDK) and apply OS updates regularly or use rebuilt images with patched packages. [2][3]
- For production security: pin exact image digests, subscribe to Adoptium/Docker Hub release notices, and run regular vulnerability scans (Trivy/Snyk) on your final images. [1][3]

If you want, I can fetch exact current sizes for specific tags/digests for your platform (linux/amd64, arm64) and list known CVEs for the latest 17-focal tags.

eclipse-temurin docker latest recommendations 2025 openjdk alternative
💡 Result:
Short answer — yes: continue using the official eclipse-temurin Docker images, but don’t rely on an unqualified "latest" tag in production. Pin to a specific major.minor (or better: the exact tag + digest), choose the OS variant you need (alpine/ubi/debian/slim/nanoserver), and prefer a minimized runtime (jlink/custom JRE or slim/jre images) when size/attack-surface matters. Good alternatives if you want a different OpenJDK build are Amazon Corretto, Azul Zulu (or Zulu Prime), BellSoft Liberica, Microsoft Build of OpenJDK and Red Hat/SAP builds — pick one with the support and platform variants you require. [1][2][3][4]
Practical recommendations
- Pin images by tag and digest, e.g. FROM eclipse-temurin:17.0.17-jdk@sha256:. Avoid using the floating "latest" tag for production. [2]
- Pick the right variant: alpine (now Alpine 3.22 default), debian/ubuntu/ubi/nanoserver or slim/minimal depending on compatibility and security needs. [1][2]
- Use jlink or multi-stage builds to produce a small runtime image (recommended on JDK 21+). [2][1]
- Track upstream releases and security fixes (Temurin release notes / DockerHub releases) and automate image updates (dependabot/renovate). [1][4]
- If you need vendor support or different licensing/patch cadence, evaluate alternatives (Corretto, Zulu, Liberica, Microsoft, Red Hat/SAP). Verify each vendor’s container image variants and support policy before switching. [3][6]
Sources
- Adoptium / Temurin release notes & blog (image changes, Alpine default, new Java 24/25 releases). [1][3]
- eclipse-temurin Docker Official Image documentation (tags, examples, jlink guidance). [2]
- Microsoft devblog on Java container image lifecycle (example of deprecation removal; illustrates importance of tracking vendor image lifecycle). [6]
- Release tracking / Docker Hub activity (useful for automating updates). [4]
If you want, I can:
- look up the current Temurin tag/digest for a specific Java version (e.g., 17/21/24/25) and give exact FROM lines, or
- compare a specific alternative vendor (Corretto/Zulu/Liberica) for image availability and support windows. Which would you prefer?

베이스 이미지 최적화 검토 필요
Eclipse Temurin은 Eclipse Foundation의 공식 OpenJDK 배포판으로 좋은 선택입니다. 다만 focal 베리언트는 다음 사항을 개선할 수 있습니다:
-
이미지 크기:
17-jdk-focal은 약 417MB이지만,17-jre-focal을 사용하면 약 266MB로 약 150MB를 절감할 수 있습니다 (애플리케이션에서 JDK가 필요하지 않다면). -
보안 고려사항: focal 베리언트는 Ubuntu 20.04 기반이며, CVE-2025-6965 등 OS 패키지 취약점의 영향을 받을 수 있습니다. 프로덕션 환경에서는:
- 정확한 이미지 다이제스트로 핀(pin)하기:
FROM eclipse-temurin:17-jdk-focal@sha256:<digest> - 정기적으로 취약점 스캔 수행 (Trivy/Snyk 활용)
- 정확한 이미지 다이제스트로 핀(pin)하기:
-
추가 최적화 옵션: 애플리케이션과 네이티브 의존성이 호환된다면, Alpine 베리언트(
17-jre-alpine)로 훨씬 더 작은 이미지를 만들 수 있습니다.
JDK 대신 JRE 사용이 필요한지, 또는 Alpine 호환성 여부를 검토해주세요.

Dockerfile lines 2-2: the base image uses eclipse-temurin:17-jdk-focal which is
larger and may expose OS CVEs; if the app does not need the JDK switch to a JRE
variant (e.g., eclipse-temurin:17-jre-focal) to reduce image size, or consider
an Alpine variant (e.g., 17-jre-alpine) if native deps are compatible;
additionally pin the image to a digest (FROM
eclipse-temurin:17-jre-focal@sha256:<digest>) and add this repository to your
build/security checklist to run regular vulnerability scans (Trivy/Snyk) and
update the pinned digest when rebuilding.
