April 2016 Summaries

An online Meetup introduced Docker Compose Version 2, a tool for managing multi-container applications, highlighting its new format and enhancements to the docker-compose.yml file. The event, titled "Containers #101: Introduction to Docker Compose V2," is available for viewing on Vimeo, with additional resources and recorded sessions accessible through the Containers #101 video channel. Attendees are encouraged to explore the example repository on GitHub and provide feedback via email. The Meetup page invites interested individuals to future events, and slides from the presentation are available for review.

Codefresh emphasizes the importance of code security by ensuring that users' code is not disclosed to third parties and by requesting only the minimal permissions necessary for automating Continuous Integration and Delivery processes. The platform assures users that their code will not be accessed by Codefresh personnel unless explicitly requested in a support scenario. Initially, when users log into Codefresh, minimal permissions are requested, with additional permissions needed only when users choose to add private repositories. Even though read/write permissions are necessary to access and clone private repositories, Codefresh guarantees not to alter any code unless specifically requested by the user. Users have the flexibility to manage access to private repositories through their User Settings, and Codefresh encourages feedback on improving security policies, inviting users to contact them with suggestions.

Codefresh has introduced a new feature that allows users to manage environment variables at the composition level rather than the service level, streamlining the process of defining external services. This functionality automatically injects environment variables whenever a new composition is launched, offering a more efficient and centralized way to handle these variables. Users can access this feature by navigating to the Compositions tab and selecting "Variables" in the upper-right corner of the code editor within their Codefresh account, which can be created for free if they do not already have one.

Otto, a tool developed by Hashicorp, aims to simplify Dockerized microservices development environments by abstracting complexity and enhancing productivity. It builds on the foundation laid by Vagrant, offering a unified deployment workflow that bridges the gap between development and production. Otto automates the management of application dependencies and leverages Docker to streamline the development process without altering the developer workflow, although it currently only supports containerizing dependencies rather than main applications. The tool uses Vagrant and Consul for local development and testing, with AWS and Terraform for infrastructure deployment. While Otto promises future support for Docker builds and tighter integration with Hashicorp's Nomad, it currently focuses on using AWS and AMIs for production deployment, with plans to expand its capabilities further.
