如何将运行 docker 与另一个 docker 容器连接到同一网络？

Question

我有一个网站 docker 容器 (Docker-A) 运行在网络上 sts_sts_network。

网站 URL : https://speech.sts:2000/

然后我写了一个测试脚本来运行网站上的自动化步骤。测试也将在 docker 中执行，使用 docker 运行命令：

docker run     -v `pwd`/reports:/opt/robotframework/reports:Z     -v `pwd`/test:/opt/robotframework/tests:Z     -e BROWSER=chrome     ppodgorsek/robot-framework:latest

由于

测试脚本失败

| FAIL |
Error: page.goto: net::ERR_NAME_NOT_RESOLVED at https://speech.sts:2000/

如何让docker运行到达网站？

这是 docker 文件：

您可以创建一个 Docker 网络：

docker network create sts_sts_network

然后你修改你的docker运行命令：

应用程序 1： docker run -v ... --network sts_sts_network

应用程序 2： docker run -v ... --network sts_sts_network
