Today, in the Docker, we are able to easily package our applications with containers and deploy them on our servers and run them. However, talking about how to stop the Docker container in the running and terminate the program correctly is a very worthwhile topic to discuss.
In fact, in our daily projects,

We can use Docker to deploy Python applications in a simple and efficient manner. at the same time, we also have some best practices to help us complete the deployment happily. Of course, it doesn't mean that these best practices are the only way to complete the deployment, but our team finds them highly available and easy to maintain.

Google Cadvisor is a great tool for monitoring Docker containers, but it only shows real-time data by default and does not store historical data. In order to store and display historical data, custom displays, you can integrate Cadvisor with Influxdb, Grafana, a foreign expert Brian Christner wrote an article "How to setup Docker monitoring", Describes the deployment method.Brian's approach is to manually r
ports: - "49080:8080"It tells us that the 8080 port of the Docker image is mapped to 49080 of the host, so you can access it by accessing http://localhost:49080. If you use Boot2docker, you can get the IP of the virtual machine via the following command:boot2docker ipThe VM‘s Host only interface IP address is: 192.168.59.103The returned result is your IP, which can be accessed through http://192.168.59.103:49080 in this example.How to
