Docker Compose Files Can Be Edited Via Visual Studio Code

At DockerCon, a demo during a keynote shows Visual Studio Code capable of editing of Docker Compose files via an extension that will be available at the next update.

Visual Studio Code isn't quite ready to be used for provisioning Docker containers, but the capabilities are there for it to be used, at the very least, to edit Docker Compose files. Erich Gamma, a Microsoft Visual Studio Code Development Lead, blogs about a demo by Microsoft VSC team member Sean McBreen at a keynote earlier this week at DockerCon in San Francisco.

Visual Studio Code is already capable of showing syntax coloring and snippets when opening Docker files. McBreen's demonstration went a bit further, showing how Visual Studio Code editing features worked in conjunction with Docker Compose files as if the features were native. Specifically, he showed in-context help popping up as the mouse hovered over a key, and similarly over an image. "In this case, the plugin uses the REST API provided by DockerHub to fetch meta information about a particular image and to show it in a hover," writes McBreen.

He also showed two instances of IntelliSense popping up with rules, and a variation called "dynamic IntelliSense" when hovering over images. McBreen says that this version of IntelliSense differs in that it does not "propose completions based on the context of a file, but by reaching out to some other data source." In this case, when IntelliSense encounters an image, it goes through the DockerHub API to search for images with a specific typed string.

The Visual Studio Code extension is expected to be available in a subsequent update.
