Insecure TLS Allow List

Introduction

Transport Layer Security (TLS) is the successor to and improved protocol of SSL. It works in much the same way as SSL, using encryption to protect the transfer of data and information and secure HTTP traffic.

The TLS Allow List represents a set of services in Hasura GraphQL Engine that are permitted to use self-signed CA certificates - primarily intended for use in development and staging environments. These services can be allowlisted by a host domain, and optionally a (service id) port.

Add and remove hosts from the TLS allow list

To add a host to the insecure TLS allow list in the Console go to the Settings tab (⚙) tab and click on Insecure TLS Allow List in the left sidebar. Click on Add Domain and enter the host domain and port (if applicable). Click on Add to Allow List to add the host to the allow list.

To remove the host, click the Delete button.

To add a host to the insecure TLS allow list using metadata, go to the metadata -> network.yaml file, add the host domain and port (if applicable) to the tls_allowlist section.

tls_allowlist:
  - host: localhost
    permissions:
      - self-signed
    suffix: "4183"

Apply the Metadata by running:

hasura metadata apply

To remove a host from the list, delete the entry and reapply the metadata.

To add a host to the TLS allow list using the API execute the following request with your defined host domain and port (if applicable):

POST /v1/metadata HTTP/1.1
Content-Type: application/json
X-Hasura-Role: admin

{
  "type": "add_host_to_tls_allowlist",
  "args": {
    "host": "localhost",
    "suffix": "4183",
    "permissions": ["self-signed"]
  }
}

To remove a host from the list, execute the following request with the domain you want to remove:

POST /v1/metadata HTTP/1.1
Content-Type: application/json
X-Hasura-Role: admin

{
  "type": "drop_host_from_tls_allowlist",
  "args": {
    "host": "localhost",
    "suffix": "4183"
  }
}
