如何在容器化服务器上运行容器化Cypress runner？

Question

我正在尝试对容器化的Nginx运行Cypress测试：

CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS          PORTS                                       NAMES
7c3efd24e6e6   tdd_nginx      "/docker-entrypoint.…"   19 minutes ago   Up 19 minutes   0.0.0.0:80->80/tcp, :::80->80/tcp           tdd_nginx_1

从官方docs中我了解到我可以使用docker run -it -v $PWD:/e2e -w /e2e -e CYPRESS_baseUrl=host.docker.internal cypress/included:7.7.0

我了解到了host.docker.internal，据说Cypress知道如何在特定的容器中查找localhost。

Nginx容器公开了80端口，所以我尝试了-e CYPRESS_baseUrl=host.docker.internal:80，并且没有指定端口，因为在大多数情况下，80端口是一个备用端口。

错误输出：

Cypress could not verify that this server is running:

  > http://host.docker.internal:80

We are verifying this server because it has been configured as your `baseUrl`.

Cypress automatically waits until your server is accessible before running tests.

We will try connecting to it 3 more times...
We will try connecting to it 2 more times...
We will try connecting to it 1 more time...

Cypress failed to verify that your server is running.

Please start this server and then run Cypress again.

将环境变量移到cypress.json中并没有什么不同：

{
  "baseUrl": "host.docker.internal",
  "video": false
}

Answer 1

将cypress.json更改为：

{
  "CYPRESS_BASE_URL": "host.docker.internal",
  "video": false
}

将CYPRESS_BASE_URL解析为环境变量无济于事，但将其放入文件中确实起到了作用。奇怪的是，这会带来不同的结果。
