我正在 Docker for Desktop 中进行 Confluent Admin 培训和运行实验室。 PFA docker-compose yaml 文件。
Confluent 控制中心未在浏览器中打开。我正在使用 http://localhost:9021 打开。更早它曾经打开但不再打开。我对计算机所做的唯一更改是安装 McAfee Live Safe。我什至尝试关闭防火墙，但也无济于事。
如果您有类似的经历以及您如何克服这个问题，有人可以分享吗？

谢谢 !!
最佳答案
最后......我从 Confluent Support 那里得到了答案。
实验室控制中心的版本在 30 天后过期。
这可以通过删除 PC 上的所有容器和卷来重置。
docker-compose down -v将退出并删除所有容器和卷。 docker-compose up -d命令。 现在在任何浏览器中打开控制中心之前一两分钟。
附言Docker 应该至少有 6GB 的内存来运行所有容器。
谢谢。
关于docker - 为什么是 http ://localhost:9021/not opening the Confluent Control Center?，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/64635257/
