Приглашаем опытных девопсов для работы с тремя направлениями во Future Crew: это Data Platforms, приватная связь и защита от уязвимостей периметра.

Если темы вам интересны – откликайтесь по ссылкам.

DevOps в Data Platforms

Задачи: K8s, VMWare, Linux, изоляция ресурсов (GPU, CPU, RAM), LDAP, мониторинг, участие в создании архитектуры, развитие CI/CD для ML и не только.

О команде Big Data можно мы немного рассказывали здесь.

DevOps в Membrana

К8 – одна из ключевых составляющих нашей инфраструктуры. Девопс будет работать с контейнерами, сетями, маршрутами и Kafka.

Здесь можно прочитать о технологиях и о команде.

DevOps в Cicada8

Задачи: Построение и доработка кластера K8s, настройка системы мониторинга с нуля, автоматизация развертывания и скейлинга Cicada8. Опыт работы с облачными провайдерами и понимание процессов ИБ будет плюсом.

А здесь есть ещё три вакансии в команде Cicada8.

Откликайся по ссылкам выше или отправь этот пост другу. А еще подписывайся на telegram-канал Future Crew , чтобы быть в курсе новостей компании.

Comparing Kubernetes Gateway and Ingress APIs

A couple of months ago, the new Kubernetes Gateway API graduated to beta.

Why do you need another API to handle external traffic when you have the stable Kubernetes Ingress API and dozens of implementations? What problems of the Ingress API does the new Gateway API solve? Does this mean the end of the Ingress API?

I will try to answer these questions in this article by getting hands-on with these APIs and looking at how they evolved.

GitHub Actions: Reusability, DRY Principle, Debugging and Fast Feedback

In this article, we will explore some method of workflow debugging and create a reusable workflow.

The DRY principle stands for Don’t Repeat Yourself, and it is a principle of software development that aims at reducing the repetition and code duplication. DRY principle can also apply to workflows and can be relatively easily implemented in Github Actions to avoid duplication.

We will first recap the essentials of GitHub Actions, explore methods of workflow debugging. Then, we will create a composite action to lint Terraform code and compare it with reusable workflows. Finally, we will create a simple reusable workflow to run testing of Terraform modules in parallel.

The Future of Terraform: ClickOps

Every now and then it’s important to step back from what we’re doing and think about the future. At Terrateam, we like to ask a question each quarter to get our gears turning. This quarter we asked:

What will Infrastructure as Code (IaC) look like in five years?
