Say, folder with docker-compose files was renamed or we do merging volumes etc. Then we shall rename docker volume. Because docker natively does not support renaming, we shall create it, then copy data, then inspect new volume, test and delete old one at the end

Volumes:

docker volume ls

Loopback SIP call with Asterisk

Reason

I need it for testing of new AMI/AGI/ARI library with crystal-lang;

Demo

Initial steps:

Following command will print out details of all active calls:

asterisk -rx "core show channels concise"
# Output:
# SIP/alice-00000002!asterisk.cr!!1!Up!Echo!!!!!3!77!!1572188916.4

	# cat ~/.zsh.after/elixir.zsh \| pbcopy
	elixir(){
	docker run --tty --interactive --rm --user `id -u`:`id -g` \
	--volume "$PWD":/tmp/elixir/app --workdir /tmp/elixir/app \
	--name "elixir-`basename $PWD`" elixir:alpine "$@"
	}

	alias iex="elixir iex $@"
	alias mix="elixir mix $@"

	def embedded_hash(levels, key, data)
	if levels == 0
	{key => data}
	else
	{key => embedded_hash(levels-1, key, data)}.merge(data)
	end
	end
