cloudformation部署后脚本

Question

I have an npm script called db:migrate that I want to run after every deployment on aws. That script runs a file called migrate.js (when present) which takes care of doing db migrations.

I'm using aws cloudformation for deployments, but I'm not sure what the best way is to have some form of post deployment script that would run that script: npm run db:migrate.

I thought there might be some form of cloudformation post deploy hook that I could use, but all I found are cloudformation custom resources. Apparently, I could trigger a lambda function after each deployment. The problem is that I don't know how I could access the ECS container from the lambda function in order to run the db:migrate script.

I'd appreciate any insights.
