Castopod in the pasture
Castopod 1.15.5 (peers/castopod.sh): the official image on the shared MySQL, its podcast @pod made and published through its admin pages, episodes through its REST API, its fediverse queue sent by spark. scenarios/castopod.sh, 15 checks: the follow, an episode reaching alice with its sound, her like, boost and comment landing there, the unfollow, statistics (from NodeInfo2).

# Castopod 1.15.5: podcasts as ActivityPub actors, their episodes as posts with the audio. The official image (FrankenPHP
|
||||
# on 8080) on the shared MySQL (database castopod), its cache in files (the shared Redis has no database left), HTTPS
|
||||
# left to Caddy (CP_DISABLE_HTTPS). It trusts Caddy's CA through the bundle mounted as its system store. Its database
|
||||
# and superadmin come from its spark commands; its fediverse queue goes out only through `spark fediverse:broadcast`,
|
||||
# run each minute in the container. A podcast is made through its admin pages (they alone take one); episodes through
|
||||
# its REST API, switched on with basic authentication.
