gitlab-ci org-mode publish

.org | .md | .gmi | .html

Buscando automatizar la publicación de mi blog ¹, descubrí la opción de utilizar gitlab pages ² junto con gitlab CI ³, posibilitando un rápido y des-atendido deploy.

La secuencia es la siguiente:

1. edito o agrego archivo.org
2. git commit
3. git push
4. se dispara el pipeline en base al .gitlab-ci.yml
5. se inicia un job
6. se levanta una instancia de docker desde la imagen alpine-emacs
7. se clona el repo https://gitlab.com/osiux.gitlab.io/
8. se ejecuta el script index.sh que genera index.org
9. se inicia emacs e instala orgmode
10. se inicia emacs y en base a publish.el exporta a .html en el directorio public

Si todo salió bien, en menos de 3min el sitio quedó actualizado en https://osiux.gitlab.io/

Si algo salió mal, recibo un email con la notificación del error, pudiendo ver el log completo para corregir el error y repetir el proceso hasta que sea exitoso.

Lo interesante es que de esta manera, puedo editar un post usando vim desde una consola, commitear, pushear y todo resuelto, aunque también esta la alternativa de usar el editor web de gitlab desde un Firefox o cualquier otro tipo de editor que no sea Emacs, siempre que respete el formato de org-mode.

# .gitlab-ci.yml

- cat index.sh | /bin/sh
