我在 Docker 容器中的 Jenkins 中运行 Angular 12 构建，并且在尝试将资产文件复制到 dist 文件夹时看到此错误：
✖ Copying of assets failed.
Unable to copy assets: EPERM: operation not permitted, copyfile '/var/jenkins_home/workspace/MY-Web-App/src/assets/building.svg' -> '/var/jenkins_home/workspace/MY-Web-App/dist/my-web-app/assets/building.svg'
问题是在 2021 年 6 月 15 日我们更新了 Ubuntu docker 主机上的所有操作系统包之后开始的。
首先想到的是 seccomp 是错误的，但我在 docker-compose 中有这个：
jenkins:
build: ./jenkins
image: my-ci-jenkins
hostname: ....
user: root
volumes:
- /data/ci/jenkins/jenkins_home:/var/jenkins_home
- artifactsvolume:/var/jenkins_home/workspace/artifacts/dist/my-web-app
ports:
- '8080:8080'
- '50000:50000'
security_opt:
- seccomp:./jenkins/seccomp.json
depends_on:
- mariadb
- gitea
environment:
- TZ=America/Los_Angeles
- JENKINS_HOME=/var/jenkins_home
restart: always
networks:
my-ci-net:
ipv4_address: ....
除其他外，在 seccomp.json 中：
{
"defaultAction": "SCMP_ACT_ERRNO",
"syscalls": [
...
{
"name": "copyfile",
"action": "SCMP_ACT_ALLOW",
"args": null
}, ...
]
}
那么，也许是权限、NodeJS、npm？不，我目前正在以 root 身份运行该进程，已清除 node_modules，在 Jenkinsfile 中放入大量日志以查看发生了什么。我正在使用 Jenkins 管道来运行构建 - 这些是结帐、日志记录和构建步骤：
checkout scm
sh 'rm -rf ./node_modules'
sh 'npm install'
sh 'mkdir -p ./dist/my-web-app/assets'
sh 'chmod 766 ./dist/my-web-app/assets'
sh 'ls -al ./dist/my-web-app'
sh 'whoami'
sh 'pwd'
sh 'ls -al'
sh 'node --version'
sh 'npm --version'
sh 'ls -al /var/jenkins_home/workspace/My-Web-App/src/assets'
sh 'ng build --configuration=staging'
导致以下日志：

构建成功地在 dist 文件夹中创建了 main-...js 文件等，但只是不复制资产。我可以成功创建一个文件，然后将其复制到 Jenkinsfile sh 中，但不能在 Angular 构建期间复制：
[Pipeline] sh
+ touch ./dist/my-web-app/assets/me.txt
[Pipeline] sh
+ cp ./dist/my-web-app/assets/me.txt ./dist/my-web-app/assets/me-copy.txt

也许是 Angular 版本？我已经用 Angular 9、10、11 和 12 尝试过同样的事情，结果相同，所以看起来不是 Angular 导致了这个问题。 Angular 的人认为这不是 Angular 的问题：https://github.com/angular/angular-cli/issues/21198

节点，NPM？我试过 Node 12 和 14。我试过 npm cache clean --force、npm cache verify，如上所示，还删除了整个 node_modules 文件夹。
码头工人？我已经使用 jenkins/jenkins:latest 作为基础多次重建了 docker 镜像和容器
我已经阅读并尝试了来自有类似问题的人的大量 StackOverflow、Github 等评论，建议重新启动、重建、检查权限、升级等，但没有运气，同样的问题。
不确定问题出在哪里：Angular、Docker、Jenkins、config、perms、color-of-socks-im-wearing ......感谢任何建议。
