Run TiddlyWiki 5 via docker.
Install docker.
sudo docker run -d -p 8080:8080 mazzolino/tiddlywiki
Now TiddlyWiki should be running on http://localhost:8080.
The container uses a Docker volume to save the wiki data. In order not to lose sight of that, I recommend using a local folder for the volume.
sudo docker run -d -p 8080:8080 -v $(pwd)/.tiddlywiki:/var/lib/tiddlywiki mazzolino/tiddlywiki
In this example, the folder $(pwd)/.tiddlywiki is used for the data.
