A ready to use Docker image for devpi. It includes the following plugins and components:

• devpi-server, devpi-web and devpi-client
• devpi-findlinks
• devpi-cleaner
• devpi-lockdown
• devpi-json

This repository is a fork of LordGaav/docker-devpi.

Main Changes:

• Smaller base image (python:slim)
• No devpi-slack
• Pulls latest devpi

I have simplified the entrypoint.sh such that devpi-server runs as the main process instead of a background process in the container. As such, there is no need to call special commands like pgrep to check if devpi-server is still alive. Without the need for pgrep, we can use python:slim as the base image instead of usual python:latest. The final docker image size reduced from >1GB to 209MB, a space saving of about 80%.

On an internet connected computer, build the docker image using:

docker build -t tpl2go/devpi:$(date '+%Y-%m-%d') .

Within the container,devpi-server stores its packages and data within the root directory /devpi. We can use a bind mount from <devpi-vol-path> to /devpi to provision this directory as a persistent storage space within container. Additionally, we need to map port 3141 from within the container to whatever <external-port> you want the container to serve.

docker run -d -p <external-port>:3141 -v <devpi-vol-path>:/devpi \
--name devpi-server tpl2go/devpi:<dateofimagebuild>

The first time it runs, the startup script will generate a password for the root user and store it in .root_password in its storage volume.

If you want to use the LDAP plugin, you need to map the YAML configuration file into the Docker and tell devpi-server to use it:

docker run -d -p <external-port>:3141 -v <devpi-vol-path>:/devpi -v /path/to/ldap.yml:/ldap.yml \
--name devpi-server tpl2go/devpi:<dateofimagebuild> --ldap-config=/ldap.yml

By default devpi-server has a 1GB package size limit. To change this limit, add the arguments --max-request-body-size <integer size> to the docker run command.

For example, to increase size limit to 5GB:

docker run -d -p <external-port>:3141 -v <devpi-vol-path>:/devpi \
--name devpi-server tpl2go/devpi:<dateofimagebuild> --max-request-body-size 5000000000

A small helper script is provided to manipulate the running container. The script will automatically log in as the root user for running commands.

$ docker exec -it devpi-server devpi-client -h
logged in 'root', credentials valid for 10.00 hours
usage: /usr/local/bin/devpi [-h] [--version] [--debug] [-y] [-v]
                            [--clientdir DIR]
                            {quickstart,use,getjson,patchjson,list,remove,user,login,logoff,index,upload,test,push,install,refresh}
...

Alternatively, you can start an interactive shell.

$ docker exec -it devpi-server devpi-client bash
logged in 'root', credentials valid for 10.00 hours
