This repository contains infrastructure-as-code ansible configurations
for various pieces of the EmacsConf infrastructure.
ansible-galaxy collection install community.general
Production: needs prod-vars.yml, see prod-vars.yml.sample
Docker: needs docker-vars.yml, see docker-vars.yml.sample
* Wiki
** Ikiwiki
*** Prod
When you update htmlscrubber.pm in wiki/templates:
ansible-playbook -i inventory.yml prod-playbook.yml --tags wiki-plugins
ansible-playbook -i docker-inventory.yml docker-reuse-playbook.yml --tags wiki-plugins
*** Docker
Goal:
- [X] Load the wiki at http://localhost:28080
- [X] Add SSH key
- [X] Add as remote
- [X] Push to the wiki
- [ ] Have the changes show up automatically
- [X] Have ansible copy the SSH key
file:/docker:emacsconf-front:/home/ikiwiki/emacsconf.setup
Creating:
ansible-playbook -i docker-inventory.yml docker-playbook.yml --tags wiki
Reusing:
ansible-playbook -i docker-inventory.yml docker-reuse-playbook.yml --tags wiki
Copying your SSH key:
set the docker_ssh_key Ansible variable to the path of your public key
or
docker cp ~/.ssh/id_rsa.pub emacsconf-front:/home/ikiwiki/.ssh/authorized_keys2
docker exec emacsconf-front chown ikiwiki:ikiwiki /home/ikiwiki/.ssh/authorized_keys2
docker exec emacsconf-front chmod 600 /home/ikiwiki/.ssh/authorized_keys2
http://localhost:28080/
ssh localhost -p 2022
docker exec -it emacsconf-front /bin/bash
git remote add docker ssh://ikiwiki@127.0.0.1:2222/var/www/wiki.git
Debugging
ssh wiki 'cd /var/www/wiki.git; git update-ref refs/heads/master HEAD^' && git push docker 2022-pages
** Publishing
*** Prod
To run the playbook and publish the main schedule:
#+begin_src sh
ansible-playbook -i inventory.yml prod-playbook.yml --tags wiki-publish --extra-vars='{"force_publish": true}'
#+end_src
#+RESULTS:
:results:
:end:
Update a specific talk's before/nav and the main schedule: (ex: wayland)
ansible-playbook playbook.yml -e '{"slug": "wayland"}' -i inventory.yml --tags publish
Force-publish the schedule:
ansible-playbook -i inventory.yml prod-playbook.yml --tags publish -e force_publish=true
*** Docker
Creating:
ansible-playbook -i docker-inventory.yml docker-playbook.yml --tags wiki,publish
Reusing:
ansible-playbook -i docker-inventory.yml docker-reuse-playbook.yml --tags publish
With docker:
https://stackoverflow.com/questions/24738264/how-to-test-ansible-playbook-using-docker
* Pad
** Production
ansible-playbook -i inventory.yml prod-playbook.yml --tags pad,proxy
To fall back to wikimedia rewrite:
ansible-playbook -i inventory.yml prod-playbook.yml --tags proxy --extra-vars='{"use_wikimedia": true}'
You can still access pads directly with direct/p like this:
https://pad.emacsconf.org/direct/p/2022-journalism
To undo wikimedia rewrite:
ansible-playbook -i inventory.yml prod-playbook.yml --tags proxy
To prepare for a load test:
ansible-playbook -i inventory.yml prod-playbook.yml --tags pad --extra-vars='{"etherpad_load_test": true}'
** Docker
Creating:
ansible-playbook -i docker-inventory.yml docker-playbook.yml --tags pad
Reusing an existing container:
ansible-playbook -i docker-inventory.yml docker-reuse-playbook.yml --tags pad
Connecting:
docker exec -it emacsconf-pad /bin/bash
Creating pads
ansible-playbook -i docker-inventory.yml docker-reuse-playbook.yml --tags create-pads
file:/docker:emacsconf-pad:/home/etherpad/etherpad/
Getting the API key
#+NAME: pad-key
#+begin_src sh
docker exec emacsconf-pad cat /home/etherpad/etherpad/APIKEY.txt
#+end_src
#+RESULTS: pad-key
:results:
b7a15dc34cc7f6917cca6cd9a2b4b92145af7c7cd9b341af34869ab8cd3568be
:end:
#+begin_src sh :var padkey=pad-key
echo curl "http://localhost:9001/api/1/createPad?apikey=$padkey&padID=emacsconf-2022"
curl "http://localhost:9001/api/1/createPad?apikey=$padkey&padID=emacsconf-2022"
#+end_src
#+RESULTS:
:results:
curl http://localhost:9001/api/1/createPad?apikey=b7a15dc34cc7f6917cca6cd9a2b4b92145af7c7cd9b341af34869ab8cd3568be&padID=emacsconf-2022
