In front of our lab environment, only one Docker host container is running on this host. However, in a real environment, there will be multiple host containers that start, run, stop, and destroy related containers in these hosts, regardless of whether they are located in the same host.How can we manage such a multi-host environment efficiently?The first problem we faced was installing and configuring

Container. Each container can be viewed as a standalone host. The creation of container usually has an image as its template. Analogy to a virtual machine can be understood as image is the mirror of the virtual machine, and container i
Preface
We have mentioned earlier that if we build the Docker cluster, there will be the need for a Docker instance network connection across the host, and in order to save the IP resources of the host network, we try to use DOCKER0 own network connection, add Host network IP to the main node (container instance), This should be a more desirable business requirem

1. Docker Container Restart policy
The restart policy for Docker containers is a start-up strategy for production environments that can be ignored during the development process.
Docker container restarts are done by the Docker da
Part-2 container (Container) IntroductionThe Docker architecture has three levels, from high to low as follows:
Stack (Stack)
Services (Service)
Containers (Container)

and Docker, there is indeed a history. The story begins in February 2013, when the American DotCloud company released a new Linux container software Docker and set up a website to publish its first demo version (see Docker's first official blog). And almost at the same time, in March 2013, California, the young handsome boy Alex Polvi is in his garage to start h

Introduced inside Docker The image is running on the filesystem and the parameters are that it will never change. The container is an instance of the mirror runtime. when you're in Docker When you run a command on it, he runs the following actions:1. Check if the image exists2. if not, download3. Load the image run the action you wantView Local containers[[email
Docker provides a simple command of the Operation container. But his command of the container does not belong to the system.
Because it is too simple, there must be a lot of deficiencies. For example, starting order, dependency checking, failure service recovery, and so on, all need a mature system service management software to complete.

When Docker creates a container, it uses the bridge network by default, assigning its own IP and not allowing itself to be specified.In the actual deployment, we need to specify the container IP, not allow its own IP, especially when building a cluster, fixed IP is required.We can create our own bridge network: MyNet, when you create a
The Shared Volume Dev ContainerAll my dev containers share at least one volume with the host:/home, which is for easy development. For many apps, in development mode, use File-system-change-based Code-reloader to run, so that the containerIt encapsulates os/distro-level dependencies and helps validate app-as-bundled work in the initial environment without having to restart/rebuild VMS every time the code changes.As for the other, I just need to reboot (not rebuild) the
