Python calls Docker API (CentOS6.5)

An environmental background

• python-2.7.8
• Docker version 1.15 (*yum installed as 1.14, upgrade to 1.15, see next steps)

Two Get Docker container indicator "indicator feasibility analysis See note:"

• CPU:USR and System Cpu time
• Memory
• ip

Three overall steps

• Container Indicator Value Acquisition
• Docker Python API Environment setup
• Get Indicator Feasibility analysis

Four specific implementations 1 the following Python script to get the specified container ID of the IP,CPU, and memory "* Block Diagram section to introduce the Python Docker API" 2:python Docke API Installation When the API is not installed, running Python will error: No model named Docker installation steps are as follows: A: Download Setuptools        

• # wget https://pypi.python.org/packages/source/s/setuptools/setuptools-3.3.tar.gz
• # python setup.py Build
• # python setup.py Install
• • PS: If you encounter the following error:

• Yum Install zlib
• Yum Install Zlib-devel
• After the installation is complete, recompile python2.7 "Do not need to delete, only need to recompile, make, install on the line" # cd/usr/local/python-2.7.8 # make Clean # made # make install

B install pip

• # wget--no-check-certificate https://github.com/pypa/pip/archive/1.5.5.tar.gz
• #tar ZVXF 1.5.5.tar.gz
• #cd pip-1.5.5/
• #python setup.py Install "* fromsetuptools import Setup,importerror:no module named Setuptools, solve such as a"

C Installation Docker-py

• #pip Install Docker-py

     Error:

          Resolved as follows: Yum installs OpenSSL and Openssl-devel. Then recompile python.

     # yum Install OpenSSL

     # yum Install-devel

     D  Upgrade Docker version (1.14) to 1.15             

• Kill Docker running Process #killall Docker

• #获取最新更新的 Docker version #wget Http://get.docker.io/builds/Linux/x86_64/docker-latest-O Docker or: wget https:// Get.docker.com/builds/linux/x86_64/docker-latest-o Docker

• Execute permissions for Docker   chmod +x Docker

• Use the-D mode to open and disconnect the Docker process and run the Process usage parameters (&) in the background. Make sure you use the./docker version is the latest version of the path instead of the previous version of the path # perform a new version #./docker-d &

      Or you can replace the docker[under/usr/local/bin to change the original Docker to dockertemp storage for insurance purposes, but not delete it.

• Finally restart the docker:# service Docker restart

     PS: If you do not upgrade Docker, you will encounter the following error:

E   Run a python script

     # python testcpu.py
