docker network host

1. Simple topology diagramIf the Pingdocker container is ping different at this time because there is no route to the 192.168.1.0/24 network on the host, the host has the opportunity to send the data destined for the 192.168.1.0/24 network to the default route so that the container cannot be reached.2. Workaround:1. Fi

Using the-v parameter in Docker Practice 2 links the host to the relevant directory in the container (mount), so we can use this channel to put the data we want to copy with each other, so that we can use the CP command to copy the file.In addition to this approach, we can also use different commands to copy the data separately.Copy data from a container like a hostDocker provides the CP command with the fo

Docker Learning Summary of cross-host link　　Docker is a powerful feature, but it's not easy to manage Docker. The following describes a user case that you will encounter in your daily work. For example, there are now two hosts, labeled Hosta and HostB, respectively. Hosta is used to run Oracle services, and HOSTB is us

I. background I recently think of the bastion host system that my company has previously used. I think it is very convenient to use. However, my company has not set up such a system. I think it may be useful in the future. And it has been a bit of time recently, therefore, I am interested in building a bastion host system. I have referenced many documents during the building process. The most detailed docum

The recent use of C # for network development requires processing of ISO8583 messages, since some of these fields are numeric, thus involving byte-order conversions when transmitting.Byte order refers to the order in memory of data that takes up more than one byte of memory, usually in two byte order, depending on where they are located we are called the host node Order and the

process to complete all initialization work based on the above configuration, or exits with an error.2.3.3 Configuration and creation of physical containersThe init process in the container first calls the Startinitialization () function, which receives various configuration parameters from the parent process through the pipeline. The container is then configured as follows: 1. Add the init process to its specified namespace, where the init process is added to the previously created Ne

Container classificationFrom the point of view of business data, containers can be divided into two categories: stateless (stateless) containers and stateful (stateful) containers.Stateless means that the container does not need to save data while it is running, and the result of each access does not depend on the last access, such as a Web server that provides a static page.Stateful means that the container needs to save the data, and the data changes, and the results of the access depend on th

As we all know, two Docker container can be connected with link, but we also know that container can map its own port to a host, such as a Tomcat on container A to expose the port to the host (0.0.0.0 : 58080->8080), the other MySQL on container B also exposes the port to the host (0.0.0.0:53306->3306), so the question
