2tefan/cimg-base-buildx repository overview

⁠cimg-base-buildx

Did you ever want to use the new buildx features⁠ in CircleCI, but didn't find a good base image? This is the solution to your problem, you can just download this repository and create a new base image as often as you desire.

The tag is always like this: ${CIMG_VERSION}-${BUILDX_VERSION}. This means that e.g. 2tefan/cimg-base-buildx:stable-18.04-0.4.1 is using cimg version stable-18.04 and it is using buildx version 0.4.1.

⁠Building

To build a new image, you can just use the build.sh script. This will build with the default cimg & buildx version (currently stable-18.04 & 0.4.1), but you can specify them with the following arguments:

⁠Arguments

To set the cimg version:

• --cimg=
• --cimg-version=
• --cv=
• --CIMG_VERSION=

To set the buildx version:

• --buildx=
• --buildx-version=
• --bv=
• --BUILDX_VERSION=

If you want the script to automatically upload the image to dockerhub, you can specify the docker repository and if you want it to be pushed:

To set the docker repository:

• --dockerrepo=
• --docker-repository=
• --dr=
• --DOCKER_REPOSITORY=

If you want to push it:

• --push
• -p

⁠Example

To build it with cimg version stable-18.04, buildx version 0.4.1 and push it to 2tefan/cimg-base-buildx:stable-18.04-0.4.1 the following command would be needed:

./build.sh -p --cimg=stable-18.04 --buildx=0.4.1 --dockerrepo=2tefan/cimg-base-buildx

But because the default values could also be used, it can be shortened to:

./build.sh -p
