Mastodon bot: RSS

Script origin

This script initialy comes from www.bentasker.co.uk

Some changes have been made in order to use YAML instead of JSON for the feed list, and the feed listing now allows to pass some more data, such as "sensitive" for content-warning tag (which would apply to the whole feed), and custom, static tags.

Parameters

The following parameters are supported, and should passed as environment variables.

HASH_DIR

Set the hash directory. String. Defaults to /hashdir

INCLUDE_AUTHOR

Display entry author or not. Boolean. Defaults to True

CW_TAG

For feed using tags, allows to switch the "content warning" flag for the post entry if this CW_TAG is set. String. Defaults to content-warning

MASTODON_URL

Set the Mastodon instance URL. String. Defaults to https://mastodon.social

MASTODON_TOKEN

Set the mastodon authentication token. String. Mandatory.

MASTODON_VISIBILITY

Set the visibility of the content. String. Defaults to public

DRY_RUN

Toggle mode - if yet to Y will not actually send data to mastodon, but output what would have been sent. Char. Defaults to N

SKIP_TAGS

For feed using tags, allow to not show the specified tags. Coma separated value.

LAST_ENTRIES

Sets the maximal amount of entries to show. Integer. Defaults to 10

Running

Building the container

buildah bud --format docker -f Dockerfile -t mastobot:latest .

Running the container in test mode

mkdir -p hashdir
podman  run --rm \
    -e MASTODON_TOKEN="<token>" \
    -e MASTODON_URL="https://mastodon.bentasker.co.uk" \
    -v $PWD/feeds.yaml:/app/feeds.yaml:Z,ro \
    -v $PWD/hashdir:/hashdir:Z \
    -e DRY_RUN="Y" \
    mastobot:latest

Actually run the bot

mkdir -p hashdir
podman  run --rm \
    -e MASTODON_TOKEN="<token>" \
    -e MASTODON_URL="https://mastodon.bentasker.co.uk" \
    -v $PWD/feeds.yaml:/app/feeds.yaml:Z,ro \
    -v $PWD/hashdir:/hashdir:Z \
    -e DRY_RUN="N" \
    mastobot:latest

SELinux

If you're running as a standard user, in your home directory, you may face some SELinux denials. In order to sort this out, you can pass the following option to podman:

--security-opt label=disable

Also, if you want to run multiple bots using the same hashdir (not a good idea, but..), you will need to modify the command and replace the Z by a z on the volume.
