[linear]

ENG-9828 CI Support

# get rollout information for production channel
# in this example we've rolled out 20% of users to hotfix-branch
> eas channel:rollout —non-interactive —action view production
{
  defaultBranch: ‘production’,
  rolledOutBranch: ‘hotfix-branch’,
  percentRolledOut: 20,
  updatedAt: ‘2023-11-24T09:53:01.155Z’
}

Then your CI could have any kind of customizable logic. In this example, there is a cron job, and if the last update was more than 1 day ago, we edit the rollout to 40%:

// Assume we load the rollout information into obj.
const lastUpdated = new Date(obj.updatedAt);

// Get the current date and time.
const now = new Date();

// Check if the difference is more than 1 day.
const differenceInDays = getDifference(lastUpdated, now);
if (differenceInDays > 1) {
  // Edit the rollout to 40%
  spawnAsync(`eas channel:rollout --non-interactive —-action edit --percent 40 production`);
}
