ICYMI: From Docker Straight to AWS Built-in

In July we announced a new strategic partnership with Amazon to integrate the Docker experience you already know and love with Amazon Elastic Container Service (ECS) with AWS Fargate. Over the last couple of months we have worked with the community on the beta experience in Docker Desktop Edge. Today we are excited to bring this experience to our entire community in Docker Desktop stable, version 2.3.0.5.

You can watch Carmen Puccio (Amazon) and myself (Docker) and view the original demo in the recording of our latest webinar here.

What started off in the beta as a Docker plugin experience docker ecs has been pulled into Docker directly as a familiar docker compose flow. This is just the beginning, and we could use your input so head over to the Docker Roadmap and let us know what you want to see as part of this integration.

There is no better time to try it. Grab the latest Docker Desktop Stable. Then check out my example application which will walk you through everything you need to know to deploy a Python application locally in development and then again directly to Amazon ECS in minutes not Continue reading

Docker Support for the New GitHub Container Registry

Docker and GitHub continue to work together to make life easier for developers. GitHub today announced a new container registry: GitHub Container Registry. GitHub and Docker both occupy essential components in the developer workflow for building and deploying cloud native applications so we thought we would provide some insight into how the new tooling benefits developers.

Found at ghcr.io, the new GitHub registry adds support for anonymous pulls and decouples git repositories permissions from container registry’s permissions. This allows projects to have private git repositories with a public container registry or vice versa. Other features like OCI compliance, Helm charts, and support for GITHUB_TOKEN are expected later.

The GitHub Container Registry was built with Docker in mind so your Docker Engines and Docker Desktops will seamlessly work with this new registry. Let’s take a look at this in action over at our upcoming Docker Login GitHub Action:

name: ci on: push: branches: master jobs: login: runs-on: ubuntu-latest steps: - name: Checkout uses: actions/checkout@v2 - name: Login to GitHub Package Registry uses: docker/login-action@v1 with: registry: ghcr.io username: ${{ github.repository_owner }} password: ${{ secrets.GHCR_TOKEN }}

That is all you need to do. When Continue reading

From Docker Straight to AWS

Just about six years ago to the day Docker hit the first milestone for Docker Compose, a simple way to layout your containers and their connections. A talks to B, B talks to C, and C is a database. Fast forward six years and the container ecosystem has become complex. New managed container services have arrived bringing their own runtime environments, CLIs, and configuration languages. This complexity serves the needs of the operations teams who require fine grained control, but carries a high price for developers.

One thing has remained constant over this time is that developers love the simplicity of Docker and Compose. This led us to ask, why do developers now have to choose between simple and powerful? Today, I am excited to finally be able to talk about the result of what we have been working on for over a year to provide developers power and simplicity from desktop to the cloud using Compose. Docker is expanding our strategic partnership with Amazon and integrating the Docker experience you already know and love with Amazon Elastic Container Service (ECS) with AWS Fargate. Deploying straight from Docker straight to AWS has never been easier.

Shortening the developer commute with Docker and Microsoft Azure

Do you remember the first time you used Docker? I do. It was about six years ago and like many folks at the time it looked like this:

docker run -it redis

I was not using Redis at the time but it seemed like a complicated enough piece of software to put this new technology through its paces. A quick Docker image pull and it was up and running. It seemed like magic. Shortly after that first Docker command I found my way to Docker Compose. At this point I knew how to run Redis and the docs had an example Python Flask application. How hard could it be to put the two together?

version: '3'
services:
  web:
    build: .
    ports:
      - "5000:5000"
  redis:
    image: “redis”

I understood immediately how Docker could help me shorten my developer “commute.” All the time I spent doing something else just to get to the work I wanted to be doing. It was awesome!

As time passed, unfortunately my commute started to get longer again. Maybe I needed to collaborate with a colleague or get more resources then I had locally. Ok, I can run Docker in the cloud, let me see how Continue reading
