Why are you talking about an IDE? This is the Container Day conference, you fool!
We all live in a Cloud world Cloud services are everywhere
Containers are a foundation of Cloud More and more of cloud services are built on containers
Developers build the Cloud Every service, every application
But they still do it in a traditional way Installing an IDE on their computer
What about doing it different? Building for the Cloud in the Cloud
Ok, man, cut the marketing… This is a technical talk, let’s talk tech
Being a cloud developer in 2021 Or do we really need 5000$ laptops to develop an app
Let me tell you a story Your next project From: Boss boss@mycompany.com To: Developer dev@mycompany.com Hi Developer! Next Monday you will begin a new project with Big Customer. You will be in a team building a system with a distributed architecture, using Redis & MariaDB storage, Go Python and Java applications, RabbitMQ event bus, … And here you have your new laptop, a good one this time, it has 8 GB RAM!
Containers have changed the game Using on your laptop the same architecture that in production
Even for complex architectures
But a laptop is still a laptop And all those containers need lots of CPU and RAM
Setting it up takes lots of time Installing and configuring isn’t always straightforward
In an ideal world, IDEaaS Integrated Development Environment as a Service
GitPod is an open source IDEaaS Automated, ephemeral developer environments in the web
A full IDE running in a browser tab Web based IDE 🌍 ● Eclipse Theia → VS Code ● Remote ● Workspaces
But more than an IDE An IDE is just one building block of a working cloud based developer environment
No overpowered laptop needed ● Low cost ultraportable laptop ● Chromebook ● iPad* ● Android tablet*
GitPod projects are based on Git It can be used with: ● Any GitPod version: ○ GitLab ○ GitHub ○ BitBucket ● On-premises or open source version ○ Your own private Git repository
Anatomy of a GitPod project ● A default 🐳 Docker image: gitpod/workspace-full ● Two optional 📝 configuration files: .gitpod.dockerfile .gitpod.yml
Projects & Workspaces ● A workspace is a full 🐳 Docker environment ● Multiple workspaces for every project ○ For example for branches or specific commits ● Workspaces are shareable ● Communication from workspace to workspace
How much does it cost? ● SaaS version ● Free Professional Open Source plan: no limit (public projects) ● Self hosted (K8S) Open Source (Free) et Pro (29€)
Some other use-cases Unexpected good matches for GitPod
Running workshops Congratulations Horacio From: Big Conference organization@bigconference.com To: Horacio Gonzalez horacio.gonzalez@gmail.com Hi Horacio! We are happy to tell you that your workshop “Learn Web Components in two hours” has been accepted at Big Conference 2021. As we are an hybrid conference, you will have 50 attendees physically in the room and 200 remote attendees. The onboarding is critical in this setup, please be sure that attendees can easily spawn a working environment in several minutes, even with a bad network or old computers.
Example: Stencil Beers tutorial https://github.com/LostInBrittany/stencil-beers
Setting up team environments New team arrives on Monday From: Boss boss@mycompany.com To: Project Manager pm@mycompany.com Hi Project Manager! Your Shiny Project team will arrive next Monday. You will have 15 developers in the team, and they need to be productive from day one. A batch of 15 laptops and 3 servers has been sent by DHL to your office, please be sure that they are installed and working by Monday morning. Have a great weekend!
Integrated learning platform OVHcloud Managed Kubernetes course From: Training Partner <organization@training@partner.com> To: Horacio Gonzalez horacio.gonzalez@ovhcloud.com Hi Horacio! As explained by phone, we would like you to do an OVHcloud Managed Kubernetes course for our organisation. We need to be fully web based, attendees won’t be able to install anything in their computers (not even kubectl, helm or any other tool). Attendees will only have their browsers and their OVHcloud API credentials.
Making customers test new features Customer X wants to test the feature From: Boss boss@mycompany.com To: Project Manager pm@mycompany.com Hi Project Manager! Customer X has asked to test the new feature your team is working on. I have pointed to the Git repository, but they aren’t interesting in reading code, they want to test it! I have tell them that you will send them a way to test by Monday. Have a great weekend!
Code for the cloud, in the cloud
Installing GitPod Open Source You only need a Kubernetes…
Good and bad reasons Good reasons to use GitPod Open Source: ● I can’t use a SaaS to deal with my source code ○ That also means no GitHub, GitLab or BitBucket… Bad reasons to use GitPod Open Source: ● I am cheap and I don’t want to pay the SaaS ○ It’s going to cost you time and money to host it
Not a straightforward task… You need some Kubernetes skills…
If you don’t need to build it, choose a certified managed solution You get the cluster, the operator get the problems
Using OVHcloud Managed Kubernetes A easy, cost-effective solution
That’s all, folks! Thank you all!
Are you contributing to a new project with the work computer, whose locking set by the IT makes it super complicated to install tools, develop from their iPad because we are on the move and we have no more battery on the laptop, develop on the same project but with completely different settings depending on the environment, do a quick fix on a repository without having to download half of the internet on his position…? We will explain and demonstrate how to use GitPod to set up a development environment in a few minutes, how not to spend a weekend preparing for the arrival of a development team, how to use GitPod with GitLab or GitHub to provide turnkey environments for projects, workshops, training… In short, at the end of our talk, you will know how to use GitPod, and you might even be ‘hooked’ on this IDE in the cloud.
The following resources were mentioned during the presentation or are useful additional information.
