For more information about Procfiles, see the Configuring a Production Server topic. You can specify the web start command for a Node.js app in a Procfile or in the app deployment manifest. This sets max_old_space_size based on the available memory in the instance. To resolve this issue, set the OPTIMIZE_MEMORY environment variable to true (requires node v6.12.0 or greater). Node does not know how much memory it isĪllowed to use, and thus sometimes allows the garbage collector to wait past When running node apps, you might notice that instances are occasionally To also run your app locally, set the default port as 3000. You must use the PORT environment variable to determine which port yourĪpp should listen on. See the GitHub Node.js buildpack page for current information. In general, Cloud Foundry supports the two most recent versions of Node.js. You can specify the version of Node.js you want to use in the engine node of Application package fileĬloud Foundry expects a package.json in your Node.js app. To specify the versions of Node.js and npm an app requires, edit the app’s package.json, as described in “node.js and npm versions” in the nodejs-buildpack repository. The buildpack uses a default Node.js version. You can find current information about this buildpack on the Node.js buildpack release page in GitHub. About the Node.js buildpackįor information about using and extending the Node.js buildpack in Cloudįoundry, see the nodejs-buildpack repository in GitHub.

If you don’t have an account yet, you can register for a free Lite account - no credit card needed! Even for a Lite Account but beware of limited storage. The IBM registry is available for free to experiment within the IBM Cloud. Not only does it protect your images, it also scans the images for security vulnerabilities. This works fine if security is not an issue, but there are some additional advantages of using a private registry, such as the one in IBM Cloud. In my previous blog, I explained how to create a simple NodeJS application, Dockerize it, and deploy it on IBM Cloud using the public DockerHub as a registry.
