* [jjo] add DIND support to contrib/ - add contrib/dind with ansible playbook to create "node" containers, and setup them to mimic host nodes as much as possible (using Ubuntu images), see contrib/dind/README.md - nodes' /etc/hosts editing via `blockinfile` and `lineinfile` need `unsafe_writes: yes` because /etc/hosts are mounted by docker, and thus can't be handled atomically (modify copy + rename) * dind-host role: set node container hostname on creation * add "Resulting deployment" section with some CLI outputs * typo * selectable node_distro: debian, ubuntu * some fixes for node_distro: ubuntu * cpu optimization: add early `pkill -STOP agetty` * typo * add centos dind support ;) * add kubespray-dind.yaml, support fedora - add kubespray-dind.yaml (former custom.yaml at README.md) - rework README.md as per above - use some YAML power to share distros' commonality - add fedora support * create unique /etc/machine-id and other updates - create unique /etc/machine-id in each docker node, used as seed for e.g. weave mac addresses - with above, now netchecker 100% passes WoHooOO! 🎉 🎉 🎉 - updated README.md output from (1.12.1, verified netcheck) * minor typos * fix centos node creation, needs earlier udevadm removal to avoid flaky facts, also verified netcheck Ok \o/ * add Q&D test-distros.sh, back to manual /etc/machine-id hack * run-test-distros.sh cosmetics and minor fixes * run-test-distros.sh: $rc fix and minor formatting changes * run-test-distros.sh output cosmetics
