AWS SSM, confd demo

A demo project that uses confd to generate config files for applications. It uses the AWS SSM Parameter Store as backend.

Requirements

• docker
• docker-compose

Parameters in SSM

You can generate the example parameters in SSM with the following commands, just make sure you have set the AWS_PROFILE environment variable before you run them.

aws ssm put-parameter --name /dev/client-api/database/user --value client --type String
aws ssm put-parameter --name /dev/client-api/database/password --value p@ssw0rd --type SecureString

The containers

Check the docker-compose.yaml, it mounts up the target directory, where the templates will be generated, it also mounts up your ~/.aws folder so it can use the credentials. The container is passing in the AWS_PROFILE variable which is then going to be used by confd to authenticate.

The default AWS region the examples are using is eu-west-1 (Ireland).

The awscli container is not used for anything, it's just there to compare the size against the confd one. At the time I was testing the size difference was about 100MB.

Start the projects

Just run

docker-compose up --build

The template files will be generated in the target folder.
