README.md
Our CI infrastructure is built around BuildKite with some additional GitHub integration provided by https://github.com/mvines/ci-gate
Buildkite AWS CloudFormation Setup
We use AWS CloudFormation to scale machines up and down based on the current CI load. If no machine is currently running it can take up to 60 seconds to spin up a new instance, please remain calm during this time.
Agent Queues
We define two Agent Queues:
queue=default
and queue=cuda
. The default
queue should be favored and
runs on lower-cost CPU instances. The cuda
queue is only necessary for
running tests that depend on GPU (via CUDA) access -- CUDA builds may still
be run on the default
queue, and the buildkite artifact
system used to transfer build
products over to a GPU instance for testing.
AMI
We use a custom AWS AMI built via https://github.com/solana-labs/elastic-ci-stack-for-aws/tree/solana/cuda.
Use the following process to update this AMI as dependencies change:
$ export AWS_ACCESS_KEY_ID=my_access_key
$ export AWS_SECRET_ACCESS_KEY=my_secret_access_key
$ git clone https://github.com/solana-labs/elastic-ci-stack-for-aws.git -b solana/cuda
$ cd elastic-ci-stack-for-aws/
$ make build
$ make build-ami
Watch for the "amazon-ebs: AMI:" log message to extract the name of the new AMI. For example:
amazon-ebs: AMI: ami-07118545e8b4ce6dc
The new AMI should also now be visible in your EC2 Dashboard. Go to the desired AWS CloudFormation stack, update the ImageId field to the new AMI id, and apply the stack changes.
