SUMMARY

Documentation on making conductor base images is very brief and lacks detail. Existing conductor base images have filesystem items (e.g. /_ansible, /usr/bin/conductor or /usr/local/bin/conductor) that aren't mentioned in the writeup at https://docs.ansible.com/ansible-container/conductor.html#baking-your-own-conductor-base .

(I also tried to make my own Dockerfile patterned after conductor-src-dockerfile.j2 but am unable to determine where many files are supposed to come from.)

(For the record, I'm trying to make a centos:6 conductor base; I'm well aware of the python 2.6 / 2.7 situation but that is the least of the problems I'm experiencing.)

Completely valid. This will be ameliorated. Thanks!

For building the conductor image I used this Dockerfile:

FROM alpine:3.7
MAINTAINER zentavr <zentavr@hello.world>

ENV ANSIBLE_CONTAINER=1
ENV ANSIBLE_CONTAINER_VERSION=0.9.2
