aws-rolling-service-restart v0.1.14
About
This script will help you do a rolling restart of a service, taking down a container at a time and waiting for a new one to come up, then proceeding with the next container and so on.
Module Usage
This exports to functions that will be of interest: restartService and getServicesInclusters.
restartService
This is an async function with signature:
const restartService = async (cluster, serviceName) => void
getServicesInclusters
This is a helper function that will give you a list of clusters with their service names. The function signature for this is:
const getServicesInclusters = async () =>
[
{
clusterArn: 'someArn',
serviceArns: [
'serviceArns',
'serviceArns2'
]
},
]
CLI usage
Run npm install and then npm run make. This will generate the executable you can run under ./dist/app.dist.js
You only need to provide the service definition with --service and the cluster name with --cluster. Both of those can be found in the ECS console.
Example:
node ./dist/app.dist.js --cluster docker-cluster --service serviceName
