Application background:Docker is the first to run on Ubuntu and Debian, using AUFS memory. Because Docker is becoming more popular, many companies want to use it on Rhel, but the upstream kernel does not include AUFS, so Rhel cannot use Aufs.Eventually, developers developed a new back-end storage engine Devicemapper, based on existing device mapper technology, and made Docker support pluggable, and now ther

Docker container images.2 Docker FeaturesFile system isolation: Each process container runs in a completely separate root file system.Resource isolation: You can use Cgroup to assign different system resources, such as CPU and memory, to each process container.Network isolation: Each process container runs in its own network namespace, with its own virtual interface and IP address.Write-time replication: C

Network Configuration TL;DR When Docker starts, it creates a virtual interface named on the host Docker0. It randomly chooses an, and subnet from the private range defined by RFC 1918 that are does not under the host Machi NE, and assigns it to DOCKER0. Docker made the choice 172.17.42.1/16 when I started it a few minutes ago, for Example-a 16-bit, netmask prov

Docker Quick Start series (5): basic network configuration and communication during storage, docker Quick StartIntroduction Two major functional modules that are essential for a web service to run: business processing, data services, and large web services require more components, which usually requires multiple containers, however, we also need to allow network

First, the use of supervisor to manageSupervisor: Process management tool, based on C/s architecture. (It provides the Web interface to the user for querying and controlling), which allows the user to monitor and control the process of the Unix-like system.Use supervisor to better control, manage, and restart the processes we want to run.Here's a demonstration of how to use both SSH and Apache services. (Generate a new image via

Objective Data Science development environment configuration is a headache, will encounter the package version inconsistency, the wrong information is not familiar with the compilation time and so on. It's easy to be crestfallen and makes this first step in data science very difficult. And it's a completely uncommon entry threshold. Fortunately, over the past few years there have been technologies that have been able to solve this problem by buildin

Before we have deployed a Docker swarm cluster environment, we will briefly introduce the management of the swarm cluster. Cluster scheduling strategy Since it is a cluster, there is a scheduling policy, that is, the cluster contains so many sub-nodes, I exactly set a strategy to allocate it. We look at the official Docker documentation to see that Swarm's clus
