 In this repository I collect docker compose snippets that represent default solutions for containers within a stack file.
 
+## ToDo:
+
+These are things that need to be fixed up:
+- mariadb.yml: Add a few comments to make clear what can and should be changed according to neccessity.
+- mariadb.yml: Add an example for clustering settings as well.
+- naruadb.yml: Let healthcheck do more than just a ping.
+- redis.yml: Add switches for more common use cases like multiple databases or clustering.
+- diun.yml: Try to figure out how to configure the content of the setting files within the stack file to get rid of the bind mount.
