api	/sys/replication - HTTP API	<tt>/sys/replication/dr</tt>	api-http-system-replication-dr	The '/sys/replication/dr' endpoint focuses on managing general operations in Vault Enterprise Disaster Recovery replication

/sys/replication/dr

~> Enterprise Only – These endpoints require Vault Enterprise.

Check DR Status

This endpoint prints information about the status of replication (mode, sync progress, etc).

This is an authenticated endpoint.

Method	Path	Produces
GET	/sys/replication/dr/status	200 application/json

Sample Request

$ curl \
    http://127.0.0.1:8200/v1/sys/replication/dr/status

Sample Response from Primary

The printed status of the replication environment. As an example, for a primary, it will look something like:

{
  "data": {
    "cluster_id": "d4095d41-3aee-8791-c421-9bc7f88f7c3e",
    "known_secondaries": [],
    "last_wal": 241,
    "merkle_root": "56794a98e52598f35974024fba6691f047e772e9",
    "mode": "primary"
  },
}

Sample Response from Secondary

The printed status of the replication environment. As an example, for a secondary, it will look something like:

{
  "data": {
    "cluster_id": "d4095d41-3aee-8791-c421-9bc7f88f7c3e",
    "known_primary_cluster_addrs": [
      "https://127.0.0.1:8201"
    ],
    "last_remote_wal": 241,
    "merkle_root": "56794a98e52598f35974024fba6691f047e772e9",
    "mode": "secondary",
    "primary_cluster_addr": "https://127.0.0.1:8201",
    "secondary_id": "3",
    "state": "stream-wals"
  },
}

Enable DR Primary Replication

This endpoint enables DR replication in primary mode. This is used when DR replication is currently disabled on the cluster (if the cluster is already a secondary, it must be promoted).

Method	Path	Produces
POST	/sys/replication/dr/primary/enable	204 (empty body)

Parameters

• primary_cluster_addr (string: "") – Specifies the cluster address that the primary gives to secondary nodes. Useful if the primary's cluster address is not directly accessible and must be accessed via an alternate path/address, such as through a TCP-based load balancer.

Sample Payload

{}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/enable

Demote DR Primary

This endpoint demotes a DR primary cluster to a secondary. This DR secondary cluster will not attempt to connect to a primary (see the update-primary call), but will maintain knowledge of its cluster ID and can be reconnected to the same DR replication set without wiping local storage.

Method	Path	Produces
POST	/sys/replication/dr/primary/demote	204 (empty body)

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/demote

Disable DR Primary

This endpoint disables DR replication entirely on the cluster. Any secondaries will no longer be able to connect. Caution: re-enabling this node as a primary or secondary will change its cluster ID; in the secondary case this means a wipe of the underlying storage when connected to a primary, and in the primary case, secondaries connecting back to the cluster (even if they have connected before) will require a wipe of the underlying storage.

Method	Path	Produces
POST	/sys/replication/dr/primary/disable	204 (empty body)

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/disable

Generate DR Secondary Token

This endpoint generates a DR secondary activation token for the cluster with the given opaque identifier, which must be unique. This identifier can later be used to revoke a DR secondary's access.

This endpoint requires 'sudo' capability.

Method	Path	Produces
POST	/sys/replication/dr/primary/secondary-token	200 application/json

Parameters

• id (string: <required>) – Specifies an opaque identifier, e.g. 'us-east'

• ttl (string: "30m") – Specifies the TTL for the secondary activation token.

Sample Payload

{
  "id": "us-east-1"
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/secondary-token

Sample Response

{
  "request_id": "",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": null,
  "warnings": null,
  "wrap_info": {
    "token": "fb79b9d3-d94e-9eb6-4919-c559311133d6",
    "ttl": 300,
    "creation_time": "2016-09-28T14:41:00.56961496-04:00",
    "wrapped_accessor": ""
  }
}

Revoke DR Secondary Token

This endpoint revokes a DR secondary's ability to connect to the DR primary cluster; the DR secondary will immediately be disconnected and will not be allowed to connect again unless given a new activation token.

Method	Path	Produces
POST	/sys/replication/dr/primary/revoke-secondary	204 (empty body)

Parameters

• id (string: <required>) – Specifies an opaque identifier, e.g. 'us-east'

Sample Payload

{
  "id": "us-east"
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/revoke-secondary

Enable DR Secondary

This endpoint enables replication on a DR secondary using a DR secondary activation token.

!> This will immediately clear all data in the secondary cluster!

Method	Path	Produces
POST	/sys/replication/dr/secondary/enable	204 (empty body)

Parameters

• token (string: <required>) – Specifies the secondary activation token fetched from the primary.

• primary_api_addr (string: "") – Set this to the API address (normal Vault address) to override the value embedded in the token. This can be useful if the primary's redirect address is not accessible directly from this cluster (e.g. through a load balancer).

• ca_file (string: "") – Specifies the path to a CA root file (PEM format) that the secondary can use when unwrapping the token from the primary. If this and ca_path are not given, defaults to system CA roots.

• ca_path (string: "") – Specifies the path to a CA root directory containing PEM-format files that the secondary can use when unwrapping the token from the primary. If this and ca_file are not given, defaults to system CA roots.

Sample Payload

{
  "token": "..."
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/enable

Promote DR Secondary

This endpoint promotes the DR secondary cluster to DR primary. For data safety and security reasons, new secondary tokens will need to be issued to other secondaries, and there should never be more than one primary at a time.

If the DR secondary's primary cluster is also in a performance replication set, the DR secondary will be promoted into that replication set. Care should be taken when promoting to ensure multiple performance primary clusters are not activate at the same time.

If the DR secondary's primary cluster is a performance secondary, the promoted cluster will attempt to connect to the performance primary cluster using the same secondary token.

This endpoint requires a DR Operation Token to be provided as means of authorization. See the DR Operation Token API docs for more information.

!> Only one performance primary should be active at a given time. Multiple primaries may result in data loss!

Method	Path	Produces
POST	/sys/replication/dr/secondary/promote	200 application/json

Parameters

• dr_operation_token (string: <required>) - DR operation token used to authorize this request.
• primary_cluster_addr (string: "") – Specifies the cluster address that the primary gives to secondary nodes. Useful if the primary's cluster address is not directly accessible and must be accessed via an alternate path/address (e.g. through a load balancer).
• force (bool: false) - If true the cluster will be promoted even if it fails certain safety checks. Caution: Forcing promotion could result in data loss if data isn't fully replicated.

Sample Payload

{
  "dr_operation_token": "ijH8tphEHaBtgx+IvPfxDsSi2LV4j9k+Lad6eqT5cJw="
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \

Update DR Secondary's Primary

This endpoint changes a DR secondary cluster's assigned primary cluster using a secondary activation token. This does not wipe all data in the cluster.

This endpoint requires a DR Operation Token to be provided as means of authorization. See the DR Operation Token API docs for more information.

Method	Path	Produces
POST	/sys/replication/dr/secondary/update-primary	204 (empty body)

Parameters

• dr_operation_token (string: <required>) - DR operation token used to authorize this request.

• token (string: <required>) – Specifies the secondary activation token fetched from the primary. If you set this to a blank string, the cluster will stay a secondary but clear its knowledge of any past primary (and thus not attempt to connect to the previous primary). This can be useful if the primary is down to stop the secondary from trying to reconnect to it.

• primary_api_addr (string: ) – Specifies the API address (normal Vault address) to override the value embedded in the token. This can be useful if the primary's redirect address is not accessible directly from this cluster.

• ca_file (string: "") – Specifies the path to a CA root file (PEM format) that the secondary can use when unwrapping the token from the primary. If this and ca_path are not given, defaults to system CA roots.

• ca_path string: () – Specifies the path to a CA root directory containing PEM-format files that the secondary can use when unwrapping the token from the primary. If this and ca_file are not given, defaults to system CA roots.

Sample Payload

{
  "dr_operation_token": "...",
  "token": "..."
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/update-primary

Generate Disaster Recovery Operation Token

The /sys/replication/dr/secondary/generate-operation-token endpoint is used to create a new Disaster Recovery operation token for a DR secondary. These tokens are used to authorize certain DR Operation. They should be treated like traditional root tokens by being generated when needed and deleted soon after.

Read Generation Progress

This endpoint reads the configuration and process of the current generation attempt.

Method	Path	Produces
GET	/sys/replication/dr/secondary/generate-operation-token/attempt	200 application/json

Sample Request

$ curl \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-operation-token/attempt

Sample Response

{
  "started": true,
  "nonce": "2dbd10f1-8528-6246-09e7-82b25b8aba63",
  "progress": 1,
  "required": 3,
  "encoded_token": "",
  "pgp_fingerprint": "",
  "complete": false
}

If a generation is started, progress is how many unseal keys have been provided for this generation attempt, where required must be reached to complete. The nonce for the current attempt and whether the attempt is complete is also displayed. If a PGP key is being used to encrypt the final token, its fingerprint will be returned. Note that if an OTP is being used to encode the final token, it will never be returned.

Start Token Generation

This endpoint initializes a new generation attempt. Only a single generation attempt can take place at a time.

Method	Path	Produces
PUT	/sys/replication/dr/secondary/generate-operation-token/attempt	200 application/json

Parameters

• pgp_key (string: <optional>) – Specifies a base64-encoded PGP public key. The raw bytes of the token will be encrypted with this value before being returned to the final unseal key provider.

Sample Request

$ curl \
    --request PUT \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-operation-token/attempt

Sample Response

{
  "started": true,
  "nonce": "2dbd10f1-8528-6246-09e7-82b25b8aba63",
  "progress": 1,
  "required": 3,
  "encoded_token": "",
  "otp": "2vPFYG8gUSW9npwzyvxXMug0",
  "otp_length" :24,
  "complete": false
}

Cancel Generation

This endpoint cancels any in-progress generation attempt. This clears any progress made. This must be called to change the OTP or PGP key being used.

Method	Path	Produces
DELETE	/sys/replication/dr/secondary/generate-operation-token/attempt	204 (empty body)

Sample Request

$ curl \
    --request DELETE \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-operation-token/attempt

Provide Key Share to Generate Token

This endpoint is used to enter a single master key share to progress the generation attempt. If the threshold number of master key shares is reached, Vault will complete the generation and issue the new token. Otherwise, this API must be called multiple times until that threshold is met. The attempt nonce must be provided with each call.

Method	Path	Produces
PUT	/sys/replication/dr/secondary/generate-operation-token/update	200 application/json

Parameters

• key (string: <required>) – Specifies a single master key share.

• nonce (string: <required>) – Specifies the nonce of the attempt.

Sample Payload

{
  "key": "acbd1234",
  "nonce": "ad235"
}

Sample Request

$ curl \
    --request PUT \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-operation-token/update

Sample Response

This returns a JSON-encoded object indicating the attempt nonce, and completion status, and the encoded token, if the attempt is complete.

{
  "started": true,
  "nonce": "2dbd10f1-8528-6246-09e7-82b25b8aba63",
  "progress": 3,
  "required": 3,
  "pgp_fingerprint": "",
  "complete": true,
  "encoded_token": "FPzkNBvwNDeFh4SmGA8c+w=="
}

Delete DR Operation Token

This endpoint revokes the DR Operation Token. This token does not have a TTL and therefore should be deleted when it is no longer needed.

Method	Path	Produces
POST	/sys/replication/dr/secondary/operation-token/delete	204 (empty body)

Parameters

• dr_operation_token (string: <required>) - DR operation token used to authorize this request.

Sample Payload

{
  "dr_operation_token": "..."
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/operation-token/delete
