Docker - How to cleanup (unused) resources

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

delete volumes

// 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

Philip Guo summarized the problem quite well in Burrito. Are there any modern solutions to this problem ?

A nice collection of all tools provided by @pditommaso. Some subset worth trying out.

So far Sumatra/noworkflow/recipy/WorldMake appear to care most about provenance tracking; nextflow appears to be a very promising upgrade to gnu make for containerized data science pipelines.

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

defprotocol: defines an interface
deftype: create a bare-bones object which implements a protocol
defrecord: creates an immutable persistent map which implements a protocol

Typically you'll use defrecord (or even a basic map);
unless you need some specific Java inter-op,
where by you'll want to use deftype instead.

Note: defprotocol allows you to add new abstractions in a clean way Rather than (like OOP) having polymorphism on the class itself,

#How to Construct Yourself UI in KeystoneJS

KeystoneJS provide Admin UI with one set of route controllers and view templates(list&item) for all of the models.But usually,you will need some custome views other than Admin UI to display models. Although the KeystoneJS documention don't tell us much about how to contruct custome view,we can learn this from the source code in skeleton project generated by yo keystone,or you can just check out the keystone demo project's source code.We will walk through the blog feature's implementation in this demo application to demonstrate how to construct custome UI in KeystoneJS application.

As KeystoneJS documention described in Routes & Views section,there is a routes/index.js file, where we bind application's URL patterns to the controllers that load and process data, and render the appropriate template.You can find following code in it:

app.get('/blog/:catego

	# 1 Pipe from a file
	sudo docker exec --interactive CONTAINER_NAME /bin/bash < the_beginning.sh \| tee the_beginning_output.txt`

	#2a Pipe by piping
	echo "echo This is how we pipe to docker exec" \| sudo docker exec --interactive CONTAINER_NAME /bin/bash -
