Building Docker Images with heroku.yml Is Generally Available

news , Senior Director of Product Management

Last October, we announced the ability for you to deploy pre-built Docker images to Heroku via Container Registry. Today, building Docker images with heroku.yml is generally available; you can now:

  • Use git push heroku master to build your Docker images on Heroku
  • Take advantage of review apps in Docker-based projects

For most teams, using containers in production requires you to spend time setting up and maintaining complex infrastructure. By using heroku.yml to build your Docker images, you get the power and flexibility of using Docker to package your app, combined with Heroku’s high-productivity developer experience, container orchestration, an add-ons ecosystem, and managed...

Heroku Buildpack Registry: Making Buildpacks Open and Shareable

ecosystem , Senior Director of Product Management

Yesterday we announced a major step towards making buildpacks a multi-platform, open standard by contributing to Cloud Native Buildpacks, a Sandbox Project hosted by the Cloud Native Computing Foundation. Today, we are announcing that you can now easily share your buildpacks with the world, by registering them with the Heroku Buildpack Registry.

As of this post, the Buildpack Registry contains over 100 buildpacks created by authors like you. Because of your contributions, Heroku developers can easily use languages and frameworks like Meteor, Elixir, and React in their applications. If you’ve created a custom buildpack and wish to share it with the community, visit Dev Center to learn...

Container Registry & Runtime GA: Deploy Docker Images to Heroku

news , Senior Director of Product Management

In the last few years Docker has emerged as a de facto standard for packaging apps for deployment. Today, Heroku Container Registry and Runtime is generally available, allowing you to deploy your Docker images directly to Heroku.

With Container Registry, you get all of the benefits of Docker -- a great local development experience and flexibility to create your own stack -- with the benefits of running on Heroku: maintained infrastructure, container orchestration, routing, the leading add-ons ecosystem, and a world-class security & operations team.

To deploy your Docker image to Heroku, simply run one command in the directory of your Dockerfile:

$ heroku container:push web ===...

Heroku Exec and Language Runtime Metrics GA: Runtime Debugging on Heroku

news , Senior Director of Product Management

We’ve all been there -- you push your code to production and a leak causes memory usage to grow out of control. To determine the root cause of the problem, you need to be able to monitor, inspect, and debug the production application, collecting detailed data at runtime.

Today we’re making it even easier to debug your applications on Heroku, with the general availability of Language Runtime Metrics, starting with JVM languages, and Heroku Exec. Language metrics surfaces key indicators of an issue, like garbage collection activity, and heap and non-heap memory usage, on a unified timeline in the Heroku Dashboard.

After you’ve identified an issue, you can use Exec to connect to a dyno at...

You’re using a continuous delivery pipeline because it takes the manual steps out of code deployment. But when a release includes updates to a database schema, the deployment requires manual intervention and team coordination. Typically, someone on the team will log into the database and run the migration, then quickly deploy the new code to production. It's a process rife with deployment risk.

Now with Release Phase, generally available today, you can define tasks you need to run before a release is deployed to production. Simply push your code and Release Phase will automatically run your database schema migration, upload static assets to a CDN, or any other task your app needs to...

The Heroku-16 Stack is Now Generally Available

news , Senior Director of Product Management

Your Heroku applications run on top of a curated stack, containing the operating system and other components needed at runtime. We maintain the stack - updating the OS, the libraries, and ensuring that known security issues are resolved, so that you can focus on writing code.

Today we're announcing the general availability of Heroku-16, our curated stack based on Ubuntu 16.04 LTS. In addition to a new base operating system, Heroku-16 is updated with the latest libraries. If you’re a Ruby or Python developer, Heroku-16 includes 15% more development headers at build time, making it easier to compile native packages on Heroku. Finally, Heroku-16 offers a better local development...
