My first blog post on OpenFaaS.com shows how you can run open-source serverless functions on AWS Fargate
This article explains reasons for choosing AWS Fargate and simple steps to install the software and create your first function.

Note: I’m sure there are better ways of doing this!
I wanted a convenient way to switch aws command line environment variables based on my desired profile
Below are the environment variables a wanted to swap based on configured profiles
Name | Description |
---|---|
AWS_ACCESS_KEY_ID | AWS access key. |
AWS_SECRET_ACCESS_KEY | AWS secret key. Access and secret key variables override credentials stored in credential and config files. |
AWS_DEFAULT_REGION | AWS region. This variable overrides the default region of the in-use profile, if set. |
You can configure your credentials profiles in ~/.aws/credentials.
[default] aws_access_key_id=AKIAIOSFODNN7123456890 aws_secret_access_key=wJalrXUtnFEMI/K7MDENG/bPxRfiCY123456890 [ed] aws_access_key_id=AKIAI44QH8DHB123456890 aws_secret_access_key=je7MtGbClwBF/2Zp9Utk/h3yCo8nvb123456890
And your other settings in ~/.aws/config
[default] output = json region = us-east-1 [profile ed] output = json region = eu-west-1
> Note you can create these by hand or use `aws config –profile’ which is easier
The function below is really simple and uses aws config get
to set the appropriate environment variable for the profile you have selected
function aws-profile -- 'Switch aws profile' set -gx AWS_ACCESS_KEY_ID (aws configure get --profile $argv aws_access_key_id) set -gx AWS_SECRET_ACCESS_KEY (aws configure get --profile $argv aws_secret_access_key) set -gx AWS_DEFAULT_REGION (aws configure get --profile $argv region) echo Profile switched to $argv echo AWS_ACCESS_KEY_ID $AWS_ACCESS_KEY_ID echo AWS_SECRET_ACCESS_KEY $AWS_SECRET_ACCESS_KEY echo AWS_DEFAULT_REGION $AWS_DEFAULT_REGION end
$ aws-profile ed Profile switched to ed AWS_ACCESS_KEY_ID AKIAI44QH8DHB123456890 AWS_SECRET_ACCESS_KEY je7MtGbClwBF/2Zp9Utk/h3yCo8nvb123456890 AWS_DEFAULT_REGION eu-west-1
