更新内容

还是整了个公开的仓库用来扔这些东西，后面更新直接在仓库更新了，文章懒得改了

N9E - 夜莺 Nightingale

官方项目地址：https://github.com/ccfos/nightingale

已经忘了为什么23年3月份的时候弄了个Dockerfile来自行构建，就一直留下来了构建，每天凌晨也在持续构建

Dockerfile

FROM ubuntu:jammy
ARG N9E_VERSION
RUN apt-get update && apt-get install -y wget less && mkdir /opt/n9e
WORKDIR /opt/n9e
RUN wget -q -O n9e.tar.gz https://github.com/ccfos/nightingale/releases/download/${N9E_VERSION}/n9e-${N9E_VERSION}-linux-amd64.tar.gz && \
    tar -zxf n9e.tar.gz && rm -rf n9e.tar.gz
EXPOSE 17000
CMD ["/opt/n9e/n9e"]

categraf

官方项目地址：https://github.com/flashcatcloud/categraf

自己做镜像的原因这个还记得，是因为我用这个组件来采集prometheus的数据，然后用micrometer或者其他组件将服务的指标数据暴露成prometheus格式的数据，本身这样子使用没有什么问题，但是每一个服务都要去写categraf的配置文件，这东西又高度重复，太麻烦了，就统统扔到镜像里面了，然后把prometheus的url以及n9e的地址通过环境变量来注入，这样子就不需要写大量的重复配置文件了

实际上看对应的文件内容就能了解到是怎样进行配置的，对于我的使用场景足够了，就一直没管它

说明

为了能够每一次构建都获取到最新的版本，因此在构建的时候都会通过构建参数指定需要下载的版本，最新的版本信息是自己写了一个github actions工具进行获取，代码仓库

# 获取最新版本
- name: github-release-getter
  uses: Mystery00/github-release-getter@v1.1
  id: categraf_release
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
  with:
    repoOwner: flashcatcloud
    repoName: categraf


# 使用版本信息
- name: Build and push
  uses: docker/build-push-action@v5
  with:
    context: categraf
    platforms: |
      linux/amd64
      linux/arm64
    build-args: |
      CATEGRAF_VERSION=slim-${{ steps.categraf_release.outputs.tagName }}
    file: categraf/Dockerfile
    builder: ${{ steps.buildx.outputs.name }}
    push: true
    tags: ${{ env.DOCKER_NAMESPACE }}/${{ env.SERVICE_NAME }}:latest
    no-cache: true

懒得给这个actions写一份正式的使用说明了，将就用吧
