Please read the Quickstart guide before using the lab.
You can run the lab on Github Codespaces or your own machine.
Start "ATD Dual DC" in Codespace

WARNING: Currently only x86 hosts are supported. cEOS-lab for ARM is not yet available and it's not possible to start the lab on your MacBook yet.
Environment variables and secrets
This lab requires following environment variables and secrets to be set.
ARISTA_TOKEN - the token required to download cEOS-lab image from arista.com.
When starting the lab on Github Codespaces, the required data can be provided via Create codespace form if not yet associated with the repository. When running the lab on your own machine - set corresponding environment variables BEFORE 
opening the VSCode.
Wait until the lab is ready
When lab container starts, the postCreate.sh takes care of cEOS-lab image download and making some last minute changes in the lab environment. After that, make start shortcut is executed to start the lab.
This requires a some time. 
Please be patient. 
Sometimes cEOS-lab image download may fail. For example, due to incorrect token. In that case postCreate.sh script will fail and the lab will not be started.
You can confirm if image was imported correctly with docker image ls.
