# HackerNews -> Mastodon Bridge

This repo contains config to consume the HackerNews RSS feed (https://news.ycombinator.com/rss) and to toot the messages to https://mastodon.pub.solar/@hackernews_bot, a mastodon bot.

The dockerfile builds a container that uses [feed2toot](https://feed2toot.readthedocs.io/en/latest/use.html). All stateful data is expected to be mounted under `/data`, namely:

* `feed2toot.ini`: config file in this repo
* `feed2toot_clientcred.txt`: from `register_feed2toot_app` script
* `feed2toot_usercred.txt`: from `register_feed2toot_app` script
* `feed2toot_cache.db`: cache file to register previous posts

Docker image was built like this and pushed to registry:
```
docker build -t registry.greenbaum.cloud/library/mastodon-hackernews-feed2toot:0.0.1 .
docker push registry.greenbaum.cloud/library/mastodon-hackernews-feed2toot:0.0.1
```

Initial deployment, just for documentation, **don't run this for updates**:
```
# Run the steps from Deployment of updates section
# After initial deployment, copy secrets and cache file to volume mounted on /data
❯ find . -name 'feed2toot*' -type f
./feed2toot.ini
./secrets/feed2toot_clientcred.txt
./secrets/feed2toot_cache.db
./secrets/feed2toot_usercred.txt

❯ for FILE in $(find . -name 'feed2toot*' -type f  -printf "%f\n"); \
  do \
    docker cp ./secrets/$FILE bot_mastodon-hackernews-feed2toot_1:/data/$FILE; \
  done
❯ docker cp ./feed2toot.ini bot_mastodon-hackernews-feed2toot_1:/data/feed2toot.ini

# Uncomment external option of volume
```

Deployment of updates:
1. Get [tritonshell](https://git.greenbaum.cloud/dev/tritonshell)
2. Enter `tritonshell` for DC `cgn-1`
```
cd tritonshell
nix develop --command $SHELL
eval "$(triton env cgn-1-pub_solar)"
cd ..

# Optional
# Check for running container
docker ps -a | grep mastodon-hackernews-feed2toot
```

3. Update running container to a new version
```
docker-compose --project-name bot up --detach
```
