Container Tools

Container Tools | Container Tools 是一个项目，它提供脚本和实用程序，以使用 debootstrap 自动化创建最小的基于 Debian 的根文件系统 (rootfs)。它支持使用特定包、配置进行自定义，并集成容器化环境的安全扫描。可以很容易地扩展到其他发行版和项目。

Rational

当使用标准 Dockerfile 构建容器化环境时，每个自定义层都会创建：

使用此工具可以构建：

How it works:

Usage: make <target>
 ============================
 ** Debian Linux targets **
 ============================
|all|
|debian11|
|debian11-java|
|debian11-java-slim|
|debian11-corretto|
|debian11-graal|
|debian11-graal-slim|
|debian11-java-slim-maven|
|debian11-java-slim-gradle|
|debian11-graal-slim-maven|
|debian11-graal-slim-gradle|
|debian11-java-kafka|
|debian11-java-slim-kafka|

In the end it will produce the image

[Image was built successfully]
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Artifact location: debian/dist/debian11-graal-slim/debian11-graal-slim.tar
Artifact size: 124M
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Image was built successfully!
Artifact location: debian/dist/debian11-graal-slim/debian11-graal-slim.tar
To load and run this Docker image, follow these steps:
Load the Docker image from the .tar file:
  cat debian/dist/debian11-graal-slim/debian11-graal-slim.tar | docker import - debian/dist/debian11-graal-slim/debian11-graal-slim
Verify the image was loaded successfully:
  docker images
Run the Docker container:
  docker run -it <IMAGE_NAME>
  Replace <IMAGE_NAME> with the name of the image loaded in the first step.
Example:
  docker run -it debian/dist/debian11-graal-slim/debian11-graal-slim /bin/bash

How to extend

  1. Add recipe to recipes/
  2. Make sure that the link to artifact and SHA256 is correct (e.g sha256sum kafka_2.13-4.0.0.tgz):
KAFKA_VERSION='4.0.0'
KAFKA_SHA='7b852e938bc09de10cd96eca3755258c7d25fb89dbdd76305717607e1835e2aa'
KAFKA_URL="https://downloads.apache.org/kafka/${KAFKA_VERSION}/kafka_2.13-${KAFKA_VERSION}.tgz"
  1. Add target to the Makefile
debian11-java-slim-kafka:
	$(PRINT_HEADER)
	$(DEBIAN_BUILD_SCRIPT) \
			--name=$@ \
			--keyring=$(DEBIAN_KEYRING) \
			--variant=container \
			--release=stable \
			--recipes=$(JAVA_RECIPES)/java_slim.sh,$(RECIPES)/kafka/kafka.sh \
			--scripts=$(SCRIPTS)/security-scan.sh
