GitLab Runner - 错误：无法删除构建网络

Question

这是我的 gitlab-ci.yml：

image: vibraniumcore/gcc-cmake-boost-mysqlcon
#image: gitlab/dind

stages:
  - test
  - build

Run Tests:
  stage: test
  tags:
    - c++
  script:
    - mkdir build
    - cd build
    - cmake ..
    - cmake --build . --target VibraniumCoreTests
    - cd ./Tests
    - ./VibraniumCoreTests

Build VibraniumCore:
  stage: build
  tags:
    - c++
  script:
    - mkdir build
    - cd build
    - cmake ..
    - cmake --build .

Build AuthServer:
  stage: build
  tags:
  - c++
  script:
    - cd Scripts
    - ./build_authserver.sh

Build WorldServer:
  stage: build
  tags:
  - c++
  script:
    - cd Scripts
    - ./build_worldserver.sh

当我尝试运行管道时，出现此错误：

知道为什么我会收到此错误以及如何修复它吗？

Answer 1

如果您想使用

executor="docker"

设置运行器，并且尚未在托管运行器的计算机上安装 docker，则可能会遇到

"ERROR: Failed to remove network for build"

错误。

在 Ubuntu 中，尝试：

sudo apt install docker.io

然后重新运行管道。

Answer 2

您必须向您的作业添加图像。

run_tests:
 stage: test
 image: vibraniumcore/gcc-cmake-boost-mysqlcon # add this line here
 tags:
  - c++
 ...

---

或使用默认图片：

default:   # add this line here
 image: vibraniumcore/gcc-cmake-boost-mysqlcon

run_tests:
 stage: test
 ...

Answer 3

如果安装了 docker 但仍然出现错误，那么你需要授予用户使用 docker 的权限：

usermod -aG docker gitlab-runner

Answer 4

我也有同样的问题。 我使用“sudo gitlab-runner register”而不是“gitlab-runner register”，就我而言，问题已解决。

Answer 5

此问题是由于您在 gitlab runner 中使用的 executor="docker" 造成的。尝试更改为“shell”或“ssh”
