我是Docker的新手，我正在尝试创建Flink Docker镜像。 Docker镜像显示创建成功。但是我有一个疑问，我无法在Dockerfile中提到的/ opt路径中看到Flink二进制文件。
我怎么知道我的Flink Docker镜像已成功创建。
控制台的屏幕截图，少数命令集以红色突出显示，这表示可以吗？
显示Flink Docker镜像的状态已创建:
请帮我。谢谢....

最佳答案
似乎一切顺利。
要查看正在运行的容器:
docker ps
contxeng-flink-poc:1.4.0，应该在其中。
如果您确实想与Flink进行交互，则应公开一些端口。
例如，Flink仪表板在容器的端口8081上运行。
您还可以通过运行以下命令将交互式bash shell 放入容器中(如果您的容器已安装bash):
docker exec -it contxeng-flink-poc:1.4.0 bash
那是您找到Flink二进制文件的地方。
如果容器未运行，请检查其是否已构建:
docker images
如果是这样，请运行它:
docker run -d contxeng-flink-poc:1.4.0
