Linux Container runtime docker open source published 15 hours ago | Times Read | SOURCE csdn| 0 Reviews | The author Zhang Hong month Open source Linuxdocker Summary: Docker is a http://www.aliyun.com/zixun/aggregation/13423.html "> Cloud computing Platform, it utilizes Linux lxc, Aufu, Go language, Cgroup realize the independence of resources, can easily achieve the file, resources, network isolation, the ultimate goal is to achieve similar PAAs platform application isolation.

Docker is a powerful automated distributed system: Massive Web deployments, database clusters, continuous deployment systems, private PAAs, service-oriented architecture, and more. Docker uses a high-level API running at the process level to complement LXC (Linux Container), which runs the UNIX process and provides guarantees for isolation and repeatability across servers.

Notable features:

file System Isolation: Each process container runs in a completely separate root file system. Resource isolation: system resources, such as CPU and memory, can be allocated to different containers, using Cgroup. Network isolation: Each process container runs in its own network space, virtual interface and IP address. LOG: Collects and records each process container in the standard stream (Stdout/stderr/stdin) for real-time and bulk retrieval. Change Management: The modified container file system is submitted to a new image, retained for reuse to create more containers without templates or manual configuration. Interactive Shell

Use examples:

Running an interactive shell

# Download A base imagedocker pull base# Run a interactive shell in the base image,# allocate a TTY, attach stdin and Stdoutdo Cker run-i-T Base/bin/bash starts a long-running worker process

# Run Docker in daemon mode (docker-d | | echo "Docker daemon already Running") &# Start a very useful long-running processjob =$ (Docker run-d base/bin/sh-c "while true; do Echo Hello world; Sleep 1; Done ") # Collect the output of the job so fardocker logs $JOB # Kill the Jobdocker kill $JOB go to the official website to see more details: http://docker.io/
