启用 VPN 的测试容器:无法连接到 localhost:49198 的 Ryuk

问题描述 投票:0回答:2

我在 Java/maven 项目中使用 Testcontainer 进行单元和集成测试。测试按预期进行,直到我运行我用来工作的 VPN。 使用 VPN,我可以看到错误消息“Can not connect to Ryuk at localhost:49198”

以下是完整日志:

我尝试了多种方法,例如将

TESTCONTAINERS_HOST_OVERRIDE
设置为本地主机,但它不起作用。 (不知道是否考虑到了,这个变量应该在哪里设置?)

我检查了 testcontainers 的 docker 容器,无论是否有 VPN,我没有看到任何区别。

有什么想法吗? 谢谢

java docker-networking testcontainers

问题已解决: VPN 使用与 Docker 相同的 IP 范围,这意味着存在冲突。 我通过创建一个包含另一个范围的 /etc/docker/daemon.json 文件并重新启动 docker 来更改 Docker 的基本 IP 范围(您可以在此处查看:https://medium.com/codebrace/understanding-docker-networks) -并解决与 docker-subnet-ip-range-bfaad092a7ea 的冲突

我也使用 Ubuntu,但建议的解决方案对我没有帮助。 所以我想分享一个有帮助的现有解决方案。在我根据答案改变我的

/etc/docker/daemon.json
之后https://serverfault.com/a/942176 testcontainers 开始工作,同时 Cisco Anyconnect 也处于活动状态。

我将复制下面答案中的文件内容:

{
  "bip": "10.200.0.1/24",
  "default-address-pools":[
    {"base":"10.201.0.0/16","size":24},
    {"base":"10.202.0.0/16","size":24}
  ]
}
