EC2/ECS Cross Account Serverless Deploy

Serverless Framework
1

Hi Guys, I have a problem deploying serverless service on EC2/ECS environment.

Since I am deploying on EC2/ECS environment, I need to use credential_source to access instance iam role. (No file on ~/.aws/credentials)

## ~/.aws/config
[profile dev]
role_arn = arn:aws:iam::XXXXXXXXXXXX:role/CrossAccount-AssumeJenkins
output = json
credential_source=EcsContainer #Ec2InstanceMetadata on EC2
region = ap-southeast-1

It’s working on AWS cli.

aws s3 ls --profile dev #working

But when I try to deploy serverless, it’s not working.

#load config from ~/.aws/config 
export AWS_SDK_LOAD_CONFIG=1
sls deploy --stage dev --verbose

sls deploy --stage dev --verbose --aws-profile dev #also not working

Below is the error stack.

@Necromancerx in your first post you were looking at ~/.aws/config which is incorrect, then in second post you’re looking at ~/.aws/credentials which is the correct location. it looks like you need to move then entries from your first post to ~/.aws/credentials
