Our quarterly new Linux machine images are available. The updated Ubuntu 21.04 and Ubuntu 16.04 images are now available:
This April refresh updates software included in the image, which can be found below. See the machine executor docs for more information about how to use the machine executor and these images.
- Go has been updated to v1.16. Any Gophers out there know that this release was interesting with Apple Silicone and embedded file support.
- Gradle 7 also shipped in the Ubuntu 20.04 image.
- yq is now pre-installed. This is a tool similar to
jqand will help users taking advantage of Dynamic Config.
As a reminder, we have a quarterly release cadence for these images. This is the April update meaning the next two Linux image releases will be in July and October.
Ubuntu 16.04 reached the end of its LTS window this month, April 2021 and will no longer be supported by Canonical. As a result, this is the final 16.04 CircleCI machine image to be released by us. We suggest upgrading to the Ubuntu 20.04 image for continued releases and support past April, 2021.
Here’s a quick usage example:
version: 2.1 workflows: main: jobs: - build jobs: build: machine: image: ubuntu-2004:202101-01 steps: - checkout - run: echo "Do some things"
