Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Picking the right architecture = Picking the right battles + Managing trade-offs

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

The standard names for indexes in PostgreSQL are:

{tablename}_{columnname(s)}_{suffix}

where the suffix is one of the following:

pkey for a Primary Key constraint;

key for a Unique constraint;

excl for an Exclusion constraint;

idx for any other kind of index;

##Windows users:

cmder will be refered as console

##Mac Os, Ubuntu and windows users continue here:

	def flatten(list), do: flatten(list, []) \|> Enum.reverse
	def flatten([h \| t], acc) when h == [], do: flatten(t, acc)
	def flatten([h \| t], acc) when is_list(h), do: flatten(t, flatten(h, acc))
	def flatten([h \| t], acc), do: flatten(t, [h \| acc])
	def flatten([], acc), do: acc
