Stop Running Computations
To ensure a smooth upgrade, before you start to update your Code Ocean application stack, you need to make sure there are no computations running.
Using AWS Session Manager, connect to Code Ocean services instance:
Run the following command to stop computations:
Wait until all computations complete by waiting until the following CloudWatch metric reaches 0: CloudWatch > Metrics > CodeOcean > AutoScalingGroupName > SlotsUtilization
Remove scale-in Protection from Code Ocean Worker EC2 Instances
The upgrade waits for existing running workers to terminate before continuing. If you have verified that there are no running computations in the previous step, you can safely remove the scale in protection from the workers in the auto scaling group. This will complete the upgrade quicker.
In the AWS EC2 console go to EC2 > Auto Scaling Groups > workers-[id]-asg > Instance Management, then select all instances and click Actions > Remove scale-in protection
In EC2 > Auto Scaling Groups > workers-[id]-asg > Details reduce the Desired capacity to 0.
Configuring
Step 1 - Update the CloudFormation stack
Upgrading Code Ocean is done by updating the CloudFormation stack you've created upon deployment
Step 2 - Specify the template
Choose Use current template in the Prerequisite - Prepare template window.
