Github 操作 : failed with "lost connection"

Question

我们正在尝试使用 GitHub Actions 构建模板化的 gcp 实例。

我们尝试构建 Java 文件并将其从 GitHub Ubuntu 计算机传输到 GCP 实例。

我们已将 sshkey 设置为使用以下命令从 Ubuntu 计算机访问 GCP 实例 ssh-keygen -t rsa -f ~/.ssh/temp -C root -q -N ""&& chmod 400 ~/.ssh/temp && chmod 400 ~/.ssh/temp.pub && echo root: cat ~/.ssh/temp.pub > ~/.ssh/temp-formated.pub && chmod 700/home/runner/.ssh/temp-formated.pub

当我们尝试运行以下命令时，我们收到错误响应 scp -o StrictHostKeyChecking=no -i/home/runner/.ssh/temp ./code-web/target/code.war root@:/opt/code.war

该脚本在 2022 年 12 月 5 日之前运行良好，并从 2022 年 12 月 6 日开始出现错误。

我们曾经遇到过一些失败，但当我们重新运行构建时，同样的工作正常。

build.yml

# This is a basic workflow to help you get started with Actions

name: build-web

# Controls when the workflow will run
on:
  # Triggers the workflow on push or pull request events but only for the develop branch
 
  # Allows you to run this workflow manually from the Actions tab

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
      - uses: actions/checkout@v2
        with:
          ref: ${{ github.event.inputs.short_sha }}
     
     # Build using mvn
      - name: Set up JDK 8
        uses: actions/setup-java@v2
        with:
          java-version: '8'
          distribution: 'adopt'
          cache: 'maven'
      - name: Build with Maven
        run: mvn --batch-mode --update-snapshots verify

      - name: Set up Cloud SDK
        uses: google-github-actions/setup-gcloud@v0
        with:
          service_account_key: ${{ secrets.GCP_SA_KEY }}
          export_default_credentials: true

      - name: Gcloud Version
        run: gcloud --version

      - name: Run build script
        run: python ./.github/workflows/build.py ${{ github.event.inputs.short_sha }}

以下是错误日志。

我们已经尝试了同一存储库中其他构建中的多个构建 - 这些也失败了 我们已经确认该 secret 仍然有效。 并且构建也成功，因此文件“code.war”存在

任何关于如何找出根本原因的想法或任何面临类似问题的人

当我在 yml 文件中使用 ubuntu-latest 作为作业运行程序时，我也遇到了类似的问题。 我使用了 ubuntu-20.04 而不是 ubuntu-latest，然后问题就解决了。

你可以在你的 yml 文件中尝试这个

jobs:
# This workflow contains a single job called "build"
  build:
    # The type of runner that the job will run on
    runs-on: ubuntu-20.04

它对我有用。
