This document introduces Docker containers and provides examples of using Docker for networking containers across virtual machines. It discusses setting up a GRE tunnel between two VMs to connect their Docker interfaces and allow containers running on different VMs to communicate. Specific commands are provided to configure the Docker and overlay networks on each VM, establish the GRE tunnel, and run a sample container to test the connectivity.

Boycott Docker

Paolo Tonin

Docker has several issues that make it unsuitable for managing infrastructure over many years, including frequent breaking changes in new releases, difficulty cleaning up old images, and lack of kernel support. While containers provide benefits like isolation and reproducible environments, monitoring and debugging containers is challenging. Docker also adds security risks compared to traditional infrastructure stacks due to additional layers like registries and daemons.

Docker: do's and don'ts

Paolo Tonin

Docker has some issues that make it unsuitable for certain environments: (1) It has a fast release cycle that introduces breaking changes, making it difficult to maintain infrastructure over years. (2) Managing a fleet of Docker containers is harder than a single host. Modern infrastructure problems need to be resolved, like sharing permissions between containers and hosts. (3) While containers provide benefits like isolation and reproducibility, debugging is difficult and monitoring containers is not easy. Security also requires securing multiple Docker components.

Mini-Training: Docker

Betclic Everest Group Tech Team

Because we are not only shipping code and we are no longer Microsoft developers but .NET developers, it's time to open your mind and to see what is offering the OSS world. Docker is an amazing tool. Docker did popularize container and brought a way to manage it. Ok, seems to be cool, but why do developers care? - Static application environment: we know exactly what we are running - Repeatable, runnable artifact: we can deploy everywhere, anytime - Loosely coupled: we can manage, isolate, and compose at environment level easily Please have a look to this Betclic presentation and remember that .NET CLR are coming in GNU/linux world!

Measures in SQL (SIGMOD 2024, Santiago, Chile)

Julian Hyde

SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries. SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL. To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context. A talk at SIGMOD, June 9–15, 2024, Santiago, Chile Authors: Julian Hyde (Google) and John Fremlin (Google) https://doi.org/10.1145/3626246.3653374

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)

safelyiotech

Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices. These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions. Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site. The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages. Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information. This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Microservice Teams - How the cloud changes the way we work

Sven Peters

A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams? Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
