The metadata from each message are delivered as headers.

It’s possible for this output type to create the target exchange by setting exchange_declare.enabled to true, if the exchange already exists then the declaration passively verifies that the settings match.

TLS is automatic when connecting to an amqps URL, but custom settings can be enabled in the tls section.

The fields ‘key’, ‘exchange’ and ‘type’ can be dynamically set using function interpolations.

Fields

`urls`

A list of URLs to connect to. The first URL to successfully establish a connection will be used until the connection is closed. If an item of the list contains commas it will be expanded into multiple URLs.

Type: array

Requires version 3.58.0 or newer

# Examples

urls:
  - amqp://guest:guest@127.0.0.1:5672/

urls:
  - amqp://127.0.0.1:5672/,amqp://127.0.0.2:5672/

urls:
  - amqp://127.0.0.1:5672/
  - amqp://127.0.0.2:5672/

`exchange`

An AMQP exchange to publish to. This field supports interpolation functions.

Type: string

`exchange_declare`

Optionally declare the target exchange (passive).

Type: object

`exchange_declare.enabled`

Whether to declare the exchange.

Type: bool

Default: false

`exchange_declare.type`

The type of the exchange.

Type: string

Default: "direct"

Options: direct , fanout , topic , x-custom .

`exchange_declare.durable`

Whether the exchange should be durable.

Type: bool

Default: true

`key`

The binding key to set for each message. This field supports interpolation functions.

Type: string

Default: ""

`type`

The type property to set for each message. This field supports interpolation functions.

Type: string

Default: ""

`content_type`

The content type attribute to set for each message. This field supports interpolation functions.

Type: string

Default: "application/octet-stream"

`content_encoding`

The content encoding attribute to set for each message. This field supports interpolation functions.

Type: string

Default: ""

`correlation_id`

Set the correlation ID of each message with a dynamic interpolated expression. This field supports interpolation functions.

Type: string

Default: ""

`reply_to`

Carries response queue name - set with a dynamic interpolated expression. This field supports interpolation functions.

Type: string

Default: ""

`expiration`

Set the per-message TTL This field supports interpolation functions.

Type: string

Default: ""

`message_id`

Set the message ID of each message with a dynamic interpolated expression. This field supports interpolation functions.

Type: string

Default: ""

`user_id`

Set the user ID to the name of the publisher. If this property is set by a publisher, its value must be equal to the name of the user used to open the connection. This field supports interpolation functions.

Type: string

Default: ""

`app_id`

Set the application ID of each message with a dynamic interpolated expression. This field supports interpolation functions.

Type: string

Default: ""

`metadata`

Specify criteria for which metadata values are attached to messages as headers.

Type: object

`metadata.exclude_prefixes`

Provide a list of explicit metadata key prefixes to be excluded when adding metadata to sent messages.

Type: array

Default: []

`priority`

Set the priority of each message with a dynamic interpolated expression. This field supports interpolation functions.

Type: string

Default: ""

# Examples

priority: "0"

priority: ${! meta("amqp_priority") }

priority: ${! json("doc.priority") }

`max_in_flight`

The maximum number of messages to have in flight at a given time. Increase this to improve throughput.

Type: int

Default: 64

`persistent`

Whether message delivery should be persistent (transient by default).

Type: bool

Default: false

`mandatory`

Whether to set the mandatory flag on published messages. When set if a published message is routed to zero queues it is returned.

Type: bool

Default: false

`immediate`

Whether to set the immediate flag on published messages. When set if there are no ready consumers of a queue then the message is dropped instead of waiting.

Type: bool

Default: false

`timeout`

The maximum period to wait before abandoning it and reattempting. If not set, wait indefinitely.

Type: string

Default: ""

`tls`

Custom TLS settings can be used to override system defaults.

Type: object

`tls.enabled`

Whether custom TLS settings are enabled.

Type: bool

Default: false

`tls.skip_cert_verify`

Whether to skip server side certificate verification.

Type: bool

Default: false

`tls.enable_renegotiation`

Whether to allow the remote server to repeatedly request renegotiation. Enable this option if you’re seeing the error message local error: tls: no renegotiation.

Type: bool

Default: false Requires version 3.45.0 or newer

`tls.root_cas`

An optional root certificate authority to use. This is a string, representing a certificate chain from the parent trusted root certificate, to possible intermediate signing certificates, to the host certificate.

Type: string

Default: ""

# Examples

root_cas: |-
  -----BEGIN CERTIFICATE-----
  ...
  -----END CERTIFICATE-----

`tls.root_cas_file`

An optional path of a root certificate authority file to use. This is a file, often with a .pem extension, containing a certificate chain from the parent trusted root certificate, to possible intermediate signing certificates, to the host certificate.

Type: string

Default: ""

# Examples

root_cas_file: ./root_cas.pem

`tls.client_certs`

A list of client certificates to use. For each certificate either the fields cert and key, or cert_file and key_file should be specified, but not both.

Type: array

Default: []

# Examples

client_certs:
  - cert: foo
    key: bar

client_certs:
  - cert_file: ./example.pem
    key_file: ./example.key

`tls.client_certs[].cert`

A plain text certificate to use.

Type: string

Default: ""

`tls.client_certs[].key`

A plain text certificate key to use.

Type: string

Default: ""

`tls.client_certs[].cert_file`

The path of a certificate to use.

Type: string

Default: ""

`tls.client_certs[].key_file`

The path of a certificate key to use.

Type: string

`tls.client_certs[].password`

A plain text password for when the private key is password encrypted in PKCS#1 or PKCS#8 format. The obsolete pbeWithMD5AndDES-CBC algorithm is not supported for the PKCS#8 format.

Because the obsolete pbeWithMD5AndDES-CBC algorithm does not authenticate the ciphertext, it is vulnerable to padding oracle attacks that can let an attacker recover the plaintext.

Type: string

Default: ""

# Examples

password: foo

password: ${KEY_PASSWORD}
