이번 포스팅에서는 python private registry 구축과정에 대해 살펴보겠습니다.

docker private registry 구성방안은 다음 포스팅을 확인하시기 바랍니다.

 

[Docker Registry] Docker Image를 활용한 Local Registry 구축

[Spring Boot] Nexus3 도커 레지스트리

 

pypi(python package index)는 python package manager인 pip를 사용하여 python 관련 라이브러리를 인스톨할 수 있는 index로써 python 소프트웨어 저장소입니다.

python package도 역시 private 환경에서 구성하기 위해서는 private registry를 구축하여 운영해야하며, 이를 위해 pypi를 소개해 드리도록 하겠습니다.

pypi 설치

1. pypiserver 설치

[root@kubemaster ~]# pip3 install pypiserver
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

pypiserver는 말 그대로 pypi를 관리하는 server 모듈입니다.

설치가 완료되면, 특정 위치에 python package 들을 관리 할 디렉토리를 생성합니다.

[root@kubemaster ~]# mkdir pythonpackage
[root@kubemaster ~]#

2. pypi 관리 계정 생성 (htpasswd -sc htpasswd.txt admin)

[root@kubemaster ~]# yum install -y httpd-tools

centos에서 htpasswd를 사용하기 위한 httpd-tools를 설치하고, pip로 passlib를 설치합니다.

htpasswd를 사용하여 pypiserver를 기동할 때 사용할 비밀번호를 지정합니다.

3. pypiserver 기동 (pypi-server -p 8080 -P htpasswd.txt ~/pythonpackage/ &)

[root@kubemaster ~]# pypi-server -p 8080 -P htpasswd.txt ~/pythonpackage/ &
[root@kubemaster ~]#

기동 방법은 매우 간단합니다. pypi-server -p [접근 포트] -P [passwd 파일] [python package 경로]를 입력하면, 기동이 완료됩니다.

4. pypiserver 접속

접속하면 위와 같은 Welcome 화면에 접속할 수 있습니다.

5. python Package 구성

python package가 구성되면 접근하기 위한 rc 파일을 먼저 작성해 보도록 하겠습니다.

[root@kubemaster ~]# cat ~/.pypirc
[distutils]
index-servers =
  local

[local]
repository: http://192.168.56.107:8080
username: admin
password: 123qwe
[root@kubemaster ~]#

python package를 구성하기 위해 setup.py 파일을 작성합니다.

[root@kubemaster ~]# cat setup.py
#!/usr/bin/env python

from setuptools import setup

setup(
        name='python_private_registry',
        version='1.0',
        description='Python Distribution Utilities',
        author='nrson',
        author_email='son.nara@lgcns.com',
)
[root@kubemaster ~]#

이제 setup.py 파일을 기반으로 private registry에 python package를 업로드 할 수 있습니다.

현재 python에서 제공하는 python package를 확인하기 위해 다음과 같이 수행합니다.

[root@kubemaster ~]# wget https://pypi.python.org/simple

다운로드 받은 simple 파일을 열어보면 대략 20만개에 가까운 python package를 확인할 수 있습니다.

package 명은 href로 접근가능한 name이 python package입니다.

예를 들어 첫번째 0이라는 python package를 확인하기 위해서는 다음과 같이 수행할 수 있습니다.

그럼 sdist라는 python package를 업로드 해보도록 하겠습니다.

[root@kubemaster ~]#

위와같이 python3 setup.py [package] upload -r local 형식으로 업로드를 진행하면, 앞서 생성한 python package 디렉토리에 아래와 같이 업로드 된것을 확인할 수 있습니다.

[root@kubemaster pythonpackage]# pwd
/root/pythonpackage
[root@kubemaster pythonpackage]# ls
python_private_registry-1.0.tar.gz
[root@kubemaster pythonpackage]#

테스트로 생성한 파일이기에 위와 같이 파일명이 생성되었지만, 이후 python private registry를 관리하기 위해서는 setup.py 파일 명에 기준을 세워 작성하는 것이 중요할 듯 합니다.

위와 같이 업로드가 완료된 파일을 브라우저에서 확인할 수 있습니다.

6. Python Private Registry 적용하기 (pip3 install --extra-index-url)

업로드가 완료되면 이제 해당 private registry에서 Package를 다운로드 받아 설치해 보도록 하겠습니다.

[root@kubemaster pythonpackage]# pip3 install --extra-index-url http://192.168.56.107:8080 --trusted-host 192.168.56.107 python_private_registry
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

Installing collected packages: python-private-registry
  Running setup.py install for python-private-registry ... done
Successfully installed python-private-registry-1.0
[root@kubemaster pythonpackage]#

위와같이 --extra-index-url을 적용하고 Package Name을 입력하여 업로드 했던 Registry를 다운로드 받아 설치하는 것을 확인할 수 있습니다. 이를 활용하여 Python Package를 Private 환경으로 이관하거나, 개발한 Python Package를 업로드하여 관리할 수 있을 것입니다.
