|
|
|
|
|
<!--more-->
|
|
|
|
- Code: `route53`
|
|
- Since: v0.3.0
|
|
|
|
|
|
Here is an example bash command using the Amazon Route 53 provider:
|
|
|
|
```bash
|
|
AWS_ACCESS_KEY_ID=your_key_id \
|
|
AWS_SECRET_ACCESS_KEY=your_secret_access_key \
|
|
AWS_REGION=aws-region \
|
|
AWS_HOSTED_ZONE_ID=your_hosted_zone_id \
|
|
--domains example.com --email your_example@email.com --dns route53 --accept-tos=true run
|
|
```
|
|
|

## Credentials
|
|
|
|
| Environment Variable Name | Description |
|
|
|-----------------------|-------------|
|
|
| `AWS_ACCESS_KEY_ID` | Managed by the AWS client. Access key ID (`AWS_ACCESS_KEY_ID_FILE` is not supported, use `AWS_SHARED_CREDENTIALS_FILE` instead) |
|
|
| `AWS_ASSUME_ROLE_ARN` | Managed by the AWS Role ARN (`AWS_ASSUME_ROLE_ARN_FILE` is not supported) |
|
|
| `AWS_EXTERNAL_ID` | Managed by STS AssumeRole API operation (`AWS_EXTERNAL_ID_FILE` is not supported) |
|
|
| `AWS_HOSTED_ZONE_ID` | Override the hosted zone ID. |
|
|
| `AWS_PROFILE` | Managed by the AWS client (`AWS_PROFILE_FILE` is not supported) |
|
|
| `AWS_REGION` | Managed by the AWS client (`AWS_REGION_FILE` is not supported) |
|
|
| `AWS_SDK_LOAD_CONFIG` | Managed by the AWS client. Retrieve the region from the CLI config file (`AWS_SDK_LOAD_CONFIG_FILE` is not supported) |
|
|
| `AWS_SECRET_ACCESS_KEY` | Managed by the AWS client. Secret access key (`AWS_SECRET_ACCESS_KEY_FILE` is not supported, use `AWS_SHARED_CREDENTIALS_FILE` instead) |
|
|
|
|
The environment variable names can be suffixed by `_FILE` to reference a file instead of a value.
|
|

## Additional Configuration
|
|
|
|
| Environment Variable Name | Description |

|
|
| `AWS_MAX_RETRIES` | The number of maximum returns the service will use to make an individual API request |
|
|
| `AWS_POLLING_INTERVAL` | Time between DNS propagation check |
|
|
| `AWS_PROPAGATION_TIMEOUT` | Maximum waiting time for DNS propagation |
|
|
| `AWS_SHARED_CREDENTIALS_FILE` | Managed by the AWS client. Shared credentials file. |
|
|
| `AWS_TTL` | The TTL of the TXT record used for the DNS challenge |
|
|
|
|
The environment variable names can be suffixed by `_FILE` to reference a file instead of a value.

## 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 the 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.
|
|
|
|
```json
|
|
{
|
|
"Version": "2012-10-17",
|
|
"Statement": [
|
|
{
|
|
"Effect": "Allow",
|
|
"Action": "route53:GetChange",
|
|
"Resource": "arn:aws:route53:::change/*"
|
|
},
|
|
{
|
|
"Effect": "Allow",
|
|
"Action": "route53:ListHostedZonesByName",
|
|
"Resource": "*"
|
|
},
|
|
{
|
|
"Effect": "Allow",
|
|
"Action": [
|
|
"route53:ListResourceRecordSets"
|
|
],
|
|
"Resource": [
|
|
"arn:aws:route53:::hostedzone/Z11111112222222333333"
|
|
]
|
|
},
|
|
{
|
|
"Effect": "Allow",
|
|
"Action": [
|
|
"route53:ChangeResourceRecordSets"
|
|
],
|
|
"Resource": [
|
|
"arn:aws:route53:::hostedzone/Z11111112222222333333"
|
|
],
|
|
"Condition": {
|
|
"ForAllValues:StringEquals": {
|
|
"route53:ChangeResourceRecordSetsNormalizedRecordNames": [
|
|
"_acme-challenge.example.com"
|
|
],
|
|
"route53:ChangeResourceRecordSetsRecordTypes": [
|
|
"TXT"
|
|
]
|
|
}
|
|
}
|
|
}
|
|
]
|
|
}
|
|
