Add Arista cEOS to Containerlab on macOS

Arista has recently released a cEOS ARM64-based container image. This post will guide you through the process of downloading and importing the container image for Containerlab on macOS.

Prerequisite

• Containerlab with macOS on Apple Silicon

macOS

1. Point your web browser to the Arista Software Download page.

2. Log in with your Arista credentials.

3. Click the cEOSarm-lab-4.33.1-EFT3.tar.xz file link to download.

4. Save the cEOSarm-lab-4.33.1-EFT3.tar.xz file to your Downloads folder.

5. Open your favorite terminal emulator, and change to the Downloads directory.

cd ~/Downloads
copy

6. The download from the web browser may strip off the .xz file extension. Append if needed.

mv cEOSarm-lab-4.33.1-EFT3.tar cEOSarm-lab-4.33.1-EFT3.tar.xz
copy

7. Copy the file to the images directory on the clab Linux machine.

orb push -m clab cEOSarm-lab-4.33.1-EFT3.tar.xz ~/images/
copy

Containerlab

1. Log in to the clab Linux machine.

orb -m clab
copy

2. Change to the images directory.

cd ~/images
copy

3. Import the compressed archive with Docker.

docker import cEOSarm-lab-4.33.1-EFT3.tar.xz ceos:4.33.1-EFT3
copy

4. Verify the Arista cEOS container image is now listed.

docker images ceos
copy

output:

copy

Lab

1. Change to the eos directory.

cd ~/labs/eos
copy

2. Deploy the lab.

clab deploy
copy
