How do I run a node-based CLI from Docker?

[rmtuckerphx]

I am trying to accomplish something similar to: Alpine-less AWS CLI Docker Image
scar init -n lambda-aws-cli grycap/aws-cli
scar run -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY lambda-aws-cli ec2 describe-instances

But my CLI is based on Node 6.10 and is installed by:
npm install -g my-cli

What Docker image should I base this node 6.10 image on?

Then I want to be able to create and run:
scar init -n lambda-my-cli repo/my-image:latest
scar run -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY lambda-my-cli object command

Ultimately, I want to be able to execute commands on my-cli in response to S3 bucket events as in Event-Driven File-Processing Programming Model.

Instead of executing a python script it could execute either the cli command in the above 'run' example or an npm script:

scar init -s deploy.js -n lambda-my-cli -es bucket-name repo/my-image:latest
same as: npm run deploy.js

Can you create a sample that shows a Node Docker image and executing a npm-based cli?

Thanks,

Mark

Hi @rmtuckerphx.

Sorry for the delay. Thank you for your interest in SCAR. While we do not have an example that covers your use case, here are some hints:

1. Create a Dockerfile and use FROM [node:6-slim] and then install your required Node.JS CLI.
2. Upload the Docker image to a public Docker Hub repository (or create an Automated Build in Docker Hub).
3. Pass a shell-script (not a .js file) via the -s parameter of scar run. You can see an example on how to create your .js file before executing it in the mr-bayes example.

Let us know your progress.

Kind regards,
Germán.
