dotrr

Populate secrets in a dotenv file from secret providers. Currently supported providers are:

• AWS SSM Parameter Store
• AWS Secrets Manager

Installing dotrr

Precompiled binaries are available from the releases page. Alternatively, see Building the Project below.

Usage

1. Given a dotenv file name local.env.tmpl with these contents:

VAR1=aws-ssm-parameter:db-password
VAR2=aws-secretsmanager-secret:api-key
VAR3=not_a_secret

2. And you have valid AWS credentials in your AWS credential chain.

3. And following command is run:

$ dotrr resolve local.env/tmpl

4. The following will be output to stdout:

VAR1="The secret from the SSM Parameter named db-password"
VAR2="The secret from Secrets Manager secret named api-key"
VAR2="not_a_secret"

• VAR1 is resolved from SSM Parameter store since it is prefixed with aws-ssm-parameter: in the template.
• VAR2 is resolved from Secrets Manager since it is prefixed with aws-secretsmanager-secret: in the template.
• VAR3 is left untouched as it has no known resolver prefix.

Note that items that collide with a resolver prefix can be double backslash escaped to produce their intended form in the output, eg:

VAR4=\\aws-secretsmanager-secret:some-text

Results in:

VAR4="aws-secretsmanager-secret:some-text"

Building the project.
