Installing DevPi Server

1. Preferred environment is Python 2.7 with pip, virtualenv installed.

2. Install the server

   Code Block
   language bash
   mkdir -p /opt/devpi/data cd /opt/devpi scl enable python27 bash virtualenv venv source venv/bin/activate pip install --upgrade pip pip -q -U devpi-server

3. The data area needs to be initialised using

   Code Block
   language bash
   cd /opt/devpi/ source venv/bin/activate devpi-server --serverdir /opt/rh/devpi/data --init

4. The server is run with the commands

   Code Block
   language bash
   cd /opt/devpi/ source env/bin/activate # Drop the --start to run in the forground # --stop --status --log also available devpi-server --port 3141 --serverdir /opt/rh/devpi/data --start

   Warning
   title Running devpi in the background
   When running devpi in the foreground relative paths can be used for --serverdir however if using the --start option to run in the background a full path must be used or the service will fail to start.

5. A proxy can be setup and it is assumed nginx will be used and the service runner needs to be set up to redirect to the devi-pi. Example configs (but not init.d) can be generated by running the devpi-server with --gen-config

6. devpi is currently configured on the jira/bitbucket/confluence server using an apache proxy and is accessible at the following url https://devpi.renalregistry.nhs.uk. 

devpi-server is started and stopped using scripts in /opt/devpi/bin . These are called from an init.d  script located in /etc/init.d/devpi .

/etc/init.d/devpi

#!/bin/bash
#
# devpi        Startup script for the devpi server
#
# chkconfig: 2345 95 05
# description: devpi server for private package indexes and PyPI caching
#
# devpi Linux service controller script
cd "/opt/devpi/bin"

case "$1" in
    start)
        ./start-devpi.sh
        ;;
    stop)
        ./stop-devpi.sh
        ;;
    restart)
        ./stop-devpi.sh
        ./start-devpi.sh
        ;;
    *)
        echo "Usage: $0 {start|stop|restart}"
        exit 1
        ;;
esac

Upgrading the Server

/etc/init.d/devpi stop

cd /opt/devpi
scl enable python27 bash
source venv/bin/activate
pip install -U pip
pip install -U devpi-server

/etc/init.d/devpi start

...

1. Code Block
   language bash
   pip install devpi-client

2. Create a pip.ini file

   1. For your local machine:

      Code Block
      language bash
      mkdir ~/pip cd ~/pip touch pip.ini cat > pip.ini [global] index_url = https://devpi.renalregistry.nhs.uk/ukrr/dev/+simple/ [search] index = https://devpi.renalregistry.nhs.uk/ukrr/dev/ CTRL-D

      GS: Mine is in C:\Users\MY_USERNAME\AppData\Roaming\pip

   2. On rr-bamboo,
      

      1. for 32bit Python (27 and 36 in our case), add the pip.ini file to the
         C:\Windows\system32\config\systemprofile\pip
         folder

      2. For 64 bit Python (36 in our case), add the above pip.ini file to the
         C:\Windows\SysWOW64\config\systemprofile\pip
         folder

Configuring DevPi Server

1. Create a root user:

   Code Block
   language bash
   devpi use https://devpi.renalregistry.nhs.uk devpi login root --password '' devpi user -l devpi logoff

2. Create a user named 'ukrr' with the following:

   Code Block
   language bash
   devpi user -c ukrr password=registry email=rrsystems@renalregistry.nhs.uk

3. Login and create the initial indices:

   Code Block
   language bash
   devpi login ukrr --password=registry devpi index -c ukrr/release bases=root/pypi ['volatile=False'] devpi index -c ukrr/staging bases=ukrr/release ['volatile=False'] devpi index -c ukrr/dev bases=ukrr/staging ['volatile=True']

4. Initial seed of pips:

   Code Block

   devpi login ukrr devpi use https://devpi.renalregistry.nhs.uk/ukrr/release/ devpi upload --index ukrr/dev "R:\0 Software\Python\2.7_32bit\lxml-3.6.4-cp27-cp27m-win32.whl" devpi upload --index ukrr/dev "R:\0 Software\Python\2.7_32bit\pywin32-220.1-cp27-cp27m-win32.whl" devpi upload --index ukrr/dev "R:\0 Software\Python\2.7_32bit\pysvn-1.7.10-cp27-cp27m-win32.whl" devpi upload --index ukrr/dev "R:\0 Software\Python\2.7_32bit\PyQt4-4.11.4-cp27-none-win32.whl"

   
   The lxml, pywin32 and PyQt pips were obtained from http://www.lfd.uci.edu/~gohlke/pythonlibs/
   The pysvn pip has to be built using https://github.com/ferraith/pysvn-wheeler Instructions are contained in the download.

5. I noticed when I uploaded pyinstaller 3.3 (for tpckd_validation, python 3.5), devpi refused to search the main indices for other versions of same modules. Setting up a mirror allowed access to the tip version, so if you want a previous version, this needs to be uploaded by hand. Fetch the source from pypi, and build the wheel using python setup.py bdist_wheel (remember to use the right version of python for the target wheel).
