Assalamualaikum,
I created a custom page in the Ghost blog specifically to list all of the tags that were created in my blog, here is the code:
place the custom-tags.hbs and tag.hbs in your theme folder, which mine is /ghost/data/themes/attila.
If your docker runs in Docker, ensure to restart the container every time you made a modification directly in the volume of your container.
docker restart [OPTIONS] CONTAINER [CONTAINER...]and then navigate to Pages in your Ghost dashboard
You can check mine on https://ariq.nauf.al/blog/tags/
