## Description
|
|
|
|
AWS Credentials are automatically detected in the following locations and prioritized in the following order:
|
|
|
|
1. Environment variables: `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, [`AWS_SESSION_TOKEN`]
|
|
2. Shared credentials file (defaults to `~/.aws/credentials`, profiles can be specified using `AWS_PROFILE`)
|
|
3. Amazon EC2 IAM role
|
|
|
|
The AWS Region is automatically detected in the following locations and prioritized in the following order:
|
|
|
|
1. Environment variables: `AWS_REGION`
|
|
2. Shared configuration file if `AWS_SDK_LOAD_CONFIG` is set (defaults to `~/.aws/config`, profiles can be specified using `AWS_PROFILE`)
|
|
|
|
If `AWS_HOSTED_ZONE_ID` is not set, Lego tries to determine the correct public hosted zone via the FQDN.

## IAM Policy Examples
|
|
|
|
### Broad privileges for testing purposes
|
|
|
|
The following [IAM policy](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html) document grants access to the required APIs needed by lego to complete the DNS challenge.
|
|
A word of caution:
|
|
These permissions grant write access to any DNS record in any hosted zone,
|
|
so it is recommended to narrow them down as much as possible if you are using this policy in production.
|
|
|
|
```json
|
|
{
|
|
"Version": "2012-10-17",
|
|
"Statement": [
|
|
{
|
|
"Effect": "Allow",
|
|
"Action": [
|
|
"route53:GetChange",
|
|
"route53:ChangeResourceRecordSets",
|
|
"route53:ListResourceRecordSets"
|
|
],
|
|
"Resource": [
|
|
"arn:aws:route53:::hostedzone/*",
|
|
"arn:aws:route53:::change/*"
|
|
]
|
|
},
|
|
{
|
|
"Effect": "Allow",
|
|
"Action": "route53:ListHostedZonesByName",
|
|
"Resource": "*"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
### Least privilege policy for production purposes
|
|
|
|
The following AWS IAM policy document describes least privilege permissions required for lego to complete the DNS challenge.
|
|
Write access is limited to a specified hosted zone's DNS TXT records with a key of `_acme-challenge.example.com`.
|
|
Replace `Z11111112222222333333` with your hosted zone ID and `example.com` with your domain name to use this policy.
