What it does
Gives Claude concrete rules for packaging a Spring Boot 3 application as a container image or GraalVM native binary.
- Prefers Cloud Native Buildpacks (
build-image); keeps dependency and application layers separate for cache reuse - Non-root user, read-only filesystem, secrets injected at runtime only — never baked into layers
- Distinct readiness/liveness/startup probes via Actuator, plus graceful shutdown alignment
- Spring AOT with narrowly scoped
RuntimeHints; native integration tests are mandatory - Supply-chain hygiene: SBOM generation, image scanning, digest-based promotion
- Version-specific gotchas:
jarmode=toolson Boot 3.3+ vslayertoolson Boot 3.0–3.2
Who it's for
- Backend engineers shipping Spring Boot 3 services to Kubernetes/ECS
- Teams evaluating GraalVM native images to cut cold-start time
- Anyone tired of AI-generated Dockerfiles that COPY a fat jar into a root container
Example uses
- "Write a multi-stage Dockerfile for our Boot 3.3 service" → builder stage extraction with
jarmode=tools, layered copy, non-root runtime. - "My native build fails on reflection" → suggests narrow
RuntimeHintsregistration instead of blanket reflection config. - "Review our health check setup" → moves dependency checks out of liveness into readiness/startup probes.

Read the instructions in this file and follow them to help me: https://raw.githubusercontent.com/rrezartprebreza/spring-boot-skills/HEAD/skills/spring-boot-3/container-native-deployment/SKILL.md What I want: (describe your task here)
If Claude can't open the link, open it yourself and paste the contents instead.
↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.
Install in the Claude app (no terminal)
- Download the ZIP with the button below.
- In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
- Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
Install in Claude Code
Let Claude do it — paste this into Claude Code
Install the skill I found on Claude Skill Mart. Copy the skills/spring-boot-3/container-native-deployment folder from the GitHub repo rrezartprebreza/spring-boot-skills into my ~/.claude/skills/container-native-deployment/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/rrezartprebreza/spring-boot-skills.git && mkdir -p ~/.claude/skills && cp -r spring-boot-skills/skills/spring-boot-3/container-native-deployment ~/.claude/skills/⚠ This is a third-party skill. Check the source repository before installing.
- Open a terminal.
- Clone the repository:
git clone https://github.com/rrezartprebreza/spring-boot-skills.git - Create the skills directory:
mkdir -p ~/.claude/skills - Copy the whole folder so the
examples/files come along:cp -r spring-boot-skills/skills/spring-boot-3/container-native-deployment ~/.claude/skills/ - Restart Claude Code and confirm the skill shows up in your skills list.
- In a Spring Boot 3 project, ask something like "package this app as a container image" to trigger the skill.
