Docs Connect Components Inputs websocket websocket Type: InputOutput Available in: Self-Managed Connects to a websocket server and continuously receives messages. Common Advanced # Common config fields, showing default values input: label: "" websocket: url: ws://localhost:4195/get/ws # No default (required) auto_replay_nacks: true # All config fields, showing default values input: label: "" websocket: url: ws://localhost:4195/get/ws # No default (required) proxy_url: "" # No default (optional) open_message: "" # No default (optional) open_message_type: binary auto_replay_nacks: true tls: enabled: false skip_cert_verify: false enable_renegotiation: false root_cas: "" root_cas_file: "" client_certs: [] connection: max_retries: -1 # No default (optional) oauth: enabled: false consumer_key: "" consumer_secret: "" access_token: "" access_token_secret: "" basic_auth: enabled: false username: "" password: "" jwt: enabled: false private_key_file: "" signing_method: "" claims: {} headers: {} It is possible to configure an open_message, which when set to a non-empty string will be sent to the websocket server each time a connection is first established. Fields url The URL to connect to. Type: string # Examples url: ws://localhost:4195/get/ws proxy_url An optional HTTP proxy URL. Type: string open_message An optional message to send to the server upon connection. Type: string open_message_type An optional flag to indicate the data type of open_message. Type: string Default: "binary" Option Summary binary Binary data open_message. text Text data open_message. The text message payload is interpreted as UTF-8 encoded text data. auto_replay_nacks Whether messages that are rejected (nacked) at the output level should be automatically replayed indefinitely, eventually resulting in back pressure if the cause of the rejections is persistent. If set to false these messages will instead be deleted. Disabling auto replays can greatly improve memory efficiency of high throughput streams as the original shape of the data can be discarded immediately upon consumption and mutation. Type: bool Default: true 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. This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets. 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. This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets. 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 Default: "" 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. This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets. Type: string Default: "" # Examples password: foo password: ${KEY_PASSWORD} connection Customise how websocket connection attempts are made. Type: object connection.max_retries An optional limit to the number of consecutive retry attempts that will be made before abandoning the connection altogether and gracefully terminating the input. When all inputs terminate in this way the service (or stream) will shut down. If set to zero connections will never be reattempted upon a failure. If set below zero this field is ignored (effectively unset). Type: int # Examples max_retries: -1 max_retries: 10 oauth Allows you to specify open authentication via OAuth version 1. Type: object oauth.enabled Whether to use OAuth version 1 in requests. Type: bool Default: false oauth.consumer_key A value used to identify the client to the service provider. Type: string Default: "" oauth.consumer_secret A secret used to establish ownership of the consumer key. This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets. Type: string Default: "" oauth.access_token A value used to gain access to the protected resources on behalf of the user. Type: string Default: "" oauth.access_token_secret A secret provided in order to establish ownership of a given access token. This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets. Type: string Default: "" basic_auth Allows you to specify basic authentication. Type: object basic_auth.enabled Whether to use basic authentication in requests. Type: bool Default: false basic_auth.username A username to authenticate as. Type: string Default: "" basic_auth.password A password to authenticate with. This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets. Type: string Default: "" jwt BETA: Allows you to specify JWT authentication. Type: object jwt.enabled Whether to use JWT authentication in requests. Type: bool Default: false jwt.private_key_file A file with the PEM encoded via PKCS1 or PKCS8 as private key. Type: string Default: "" jwt.signing_method A method used to sign the token such as RS256, RS384, RS512 or EdDSA. Type: string Default: "" jwt.claims A value used to identify the claims that issued the JWT. Type: object Default: {} jwt.headers Add optional key/value headers to the JWT.
