You can directly reference pre-built versions of Dockerfile
by using the image
property in .devcontainer/devcontainer.json
or updating the FROM
statement in your own Dockerfile
to one of the following. An example Dockerfile
is included in this repository.
mcr.microsoft.com/devcontainers/ruby
(latest)mcr.microsoft.com/devcontainers/ruby:3
(or 3-bookworm
, 3-bullseye
to pin to an OS version)mcr.microsoft.com/devcontainers/ruby:3.3
(or 3.3-bookworm
, 3.3-bullseye
to pin to an OS version)mcr.microsoft.com/devcontainers/ruby:3.2
(or 3.2-bookworm
, 3.2-bullseye
to pin to an OS version)mcr.microsoft.com/devcontainers/ruby:3.1
(or 3.1-bookworm
, 3.1-bullseye
to pin to an OS version)Refer to this guide for more details.
You can decide how often you want updates by referencing a semantic version of each image. For example:
mcr.microsoft.com/devcontainers/ruby:1-3
(or 1-3-bookworm
, 1-3-bullseye
to pin to an OS version)mcr.microsoft.com/devcontainers/ruby:1.0-3
(or 1.0-3-bookworm
, 1.0-3-bullseye
to pin to an OS version)mcr.microsoft.com/devcontainers/ruby:1.0.0-3
(or 1.0.0-3-bookworm
, 1.0.0-3-bullseye
to pin to an OS version)However, we only do security patching on the latest non-breaking, in support versions of images (e.g. 1-3.2
). You may want to run apt-get update && apt-get upgrade
in your Dockerfile if you lock to a more specific version to at least pick up OS security updates.
See history for information on the contents of each version and here for a complete list of available tags.
Alternatively, you can use the contents of .devcontainer to fully customize your container's contents or to build it for a container host architecture not supported by the image.
Given JavaScript front-end web client code written for use in conjunction with a Ruby back-end often requires the use of Node.js-based utilities to build, this container also includes nvm
so that you can easily install Node.js. You can change the version of Node.js installed or disable its installation by updating the args
property in .devcontainer/devcontainer.json
.
"args": {
"VARIANT": "2",
"NODE_VERSION": "14" // Set to "none" to skip Node.js installation
}
