Station F - 1001 lives of containers in the cloud

You're not using containers in your startup and you're wondering if you're missing something? Or maybe you are using it but running into challenges to running outside your dev machine? Wish you could experiment new technical stacks or architectures without hurting velocity precious at your stage? During this session, we'll see how containers can help you on the development, testing and production phases. We'll also see the different containers cloud hosting possibilities and how to choose the best option for you.

   What is a container anyway?
   A way to create lightweit, portable and self-

   each of your VMs
   An OS-level isolation of your
   resources

9. 1001 lives of containers in the cloud | How containers can help developers?
   Start working on a project quickly
   Write and execute code quickly without having to install anything
   Debug my code as usual
   Use docker for CLI tools
   Create your own docker container
   Use Visual Studio Code to debug within a container

10. 1001 lives of containers in the cloud | How containers can help developers?
    Share an environment configuration with other
    developers
    Use and share pre-build containers through registries
    Hub.docker.com
    Azure Container Registry
    Use containers as a way to build your code in a CD/CI env.
    Build container pattern ( multi-stage builds)
    Use volume mapping + run command
    docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.8
    go build -v

    Deploy apps more safely
    Docker containers self-contain your app, eliminating any dependency issues
    Deploy on-demand apps for testing purposes
    Azure Container Instances
    Simplify A/B testing, carany deployments, etc…
    Azure Web Apps + Slots
    Deploy your apps anywhere!
    Your dev machine, all clouds, on customer’s infrastructure, on some IoT
    Devices (Azure IoT Hub), etc…

    Test new framework versions with ease
    FROM node:8
    WORKDIR /usr/src/app
    COPY package*.json ./
    FROM node:8.15.0-jessie
    WORKDIR /usr/src/app
    COPY package*.json ./
    Tags allows you to specifiy a specific version to
    use.
    Your own (base) images can have a tag.
    You can use latest to get the most recent
    version, this can be used in your CD/CI
    environment to test your code nightly against the
    latest/nightly version of your stack.

    Containers for production: some challenges
    How do you manage persisted state?
    How do you scale your service to several nodes?
    How do you implement a self-healing infrastructure?
    How do compose services using different containers?
    How do you aggregate logs from all containers & hosts ?
    You need an orchestrator & some
    cloud services!

    What is Kubernetes?
    Open source project started by Google in 2014
    container-centric vs. host-centric
    schedules and runs application containers across a cluster of
    machines
    portable: public, private, hybrid, multi-cloud
    extensible: modular, pluggable, hookable, composable
    self-healing: auto-placement, auto-restart, auto-replication, auto-
    scaling
    Provides resource monitoring, load balancing, naming & discovery,
    horizontal auto-scaling
    Has cloud provider integration (Eg - Azure networking, Azure disks)
