Ghost is joining the Fediverse and adding ActivityPub

[jdaviescoates]

Cool!

See https://activitypub.ghost.org/ for details

[jrl-abstract27]

@jdaviescoates Yes, great news, they seem to make good progress about it :

[jrl-abstract27]

Hi all, it seems that they are getting closer on it -> https://activitypub.ghost.org/metabolizing-mentions/?ref=build-log-newsletter

Do you know if cloudron ghost instances will have it working ?

[joseph]

@jrl-abstract27 Does the cloudron ghost package need anything special to support this? If it's part of Ghost, it probably already works.

[jdaviescoates]

@joseph it's due in Ghost 6.0 so presumably once that's released and on Cloudron we'll be ready to roll.

Has anyone got this working on cloudron yet? I just get an error

I see this in the logs

It seems Pikapods got it working with a caddyfile snippet and an env variable https://forum.ghost.org/t/activitypub-on-pikapods/59510/14

When restarting the container I see this in the logs

@samuk said in Ghost is joining the Fediverse and adding ActivityPub:

I get the same thing over on https://uniteddiversity.coop :

But on https://nzts.info and https://westdorset.news I see this:

And I can click through all of the Next buttons telling me what it's all about and then land here:

But if I search for myself either using https://mastodon.uniteddiversity.coop/@josef or @josef@uniteddiversity.coop it doesn't find me

And then after clicking on Profile it says Profile now found:

And after clicking on Preferences it just ends up here again:

So, was a bit more promising/ hopeful, but ultimately the same

[nebulon]

So @girish did some investigation on this and it turns out this is implemented in some other project for ghost https://github.com/TryGhost/ActivityPub and with the lack of upstream documentation it is not super clear yet how to deploy this and if this should be within the current ghost app package or as a standalone one. I think he can give a more detailed explanation later though.

I am actually disappointed with latest major release of Ghost, it's not even better than previous one, not just for the Activitypub which I experience issues like discussed in this thread, also in this last version, if we don't have Tinybird installed, we can't use the analytics properly, previously i can see those who clicks our newsletter, but now we can only see numbers of click without knowing which members. I really hope someone from Ghost blog can see this thread and see how the latest update is a disappointment to some loyal users
