有人能帮我解决这个Gitlab管道问题吗？

我已将Gitlab管道设置为使用docker-compose yml文件使用网格设置运行selenium测试，但似乎remoteWebdriver url连接不适用于网格设置。

在本地，当我让docker运行时，它可以正常工作，docker组合起来，然后运行testng xml文件。

解决方案：

更新gitlab yml文件

variables:
MAVEN_OPTS: -Dmaven.repo.local=.m2/repository

stages:
- build
- test

cache:
paths:
  - .m2/repository
  - target

build:
image: docker/compose:latest
stage: build
services:
  - name: docker:dind
script:
  - docker-compose up -d
tags:
  - docker-in-docker
  
test:
image: maven:latest
stage: test
script: 
  - mvn test
tags:
  - docker-in-docker
artifacts:
  paths:
    - ./TestReport/*
  expire_in: 7 days

然后，由于无法创建新的会话错误，我不得不在浏览器初始化文件中提供对特定于oreganization的远程url的引用。

Answer 1

这个错误信息..。

/root/.cache/selenium/chromedriver/linux64/100.0.4896.60/chromedriver: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory

...implies表示加载共享库 library 3有错误，因此可能已经过时，或者根本没有安装。

解决方案

按以下方式安装libnss：

sudo apt-get install
apt install libnss
apt install libnss3-dev libgdk-pixbuf2.0-dev libgtk-3-dev libxss-dev

作为另一种选择，你也可以：

sudo apt install libgconf-2-4 libatk1.0-0 libatk-bridge2.0-0 libgdk-pixbuf2.0-0 libgtk-3-0 libgbm-dev libnss3-dev libxss-dev

更新

搜寻包裹：

apt-cache search libnss
apt-file search  libnss3.so
