Github 操作：失败，"lost connection"

Question

我们正在尝试使用GitHub Actions模板构建我们的gcp实例。

我们尝试构建我们的java存档并将其从GitHub Ubuntu机器转移到GCP实例。

我们已经设置了sshkey来从Ubuntu机器访问GCP实例Ssh-keygen -t rsa -f ~/。ssh/temp -C root -q -N ",,Chmod 400 ~/。ssh/temp,,Chmod 400 ~/.ssh/temp。酒吧,,echo root:cat ~/.ssh/temp.pub>~/. ssh/temp-formated。酒吧,,Chmod 700/home/runner/.ssh/temp- formatting .pub

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

脚本在2022年12月5日之前工作正常，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，同样的工作很好。

build.yml

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

下面是错误日志。

我们已经在同一个仓库的其他构建中为其他构建尝试了多个构建-这些构建也失败了我们已经证实这个秘密还在活动。构建也是成功的因此文件"code。war"存在

是否知道如何找出根本原因或任何面临类似问题的人

我在使用ubuntu-latest作为yml文件中的作业运行程序时也遇到了类似的问题。代替ubuntu-latest我使用ubuntu-20.04那问题就解决了。

您可以在您的yml文件

中尝试此操作

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

它适合我。
