I think we’re still collectively discovering development patterns for containers. This post does a nice job of summarising a few of those patterns to emerge and takes a go at the tricky naming patterns thing.

The idea of using a regular retrospective as a way of improving how you work is popular in lots of different approaches to software development. This site has lots of different formats which can help stop regular retrospectives becoming stale.

Tools

Bottled Water is an interesting looking tool for streaming data from PostgreSQL to Kafka. You could then use that stream for warming caches, building a search index or doing any form of stream processing.

Following on from last weeks tools for secret management, Sneaker is a tool for storing secrets on S3 using Amazon Key Management Store. Excellent documentation describing various different threat models too.
