      DESCRIPTION

      This command is used to manage functions in the Event service

      OPTIONS

      -c
      --cluster

      Specifies the hostname of a node in the cluster. See the HOST FORMATS section for more information on specifying a hostname.

      -u
      --username <username>

      Specifies the username of the user executing the command. If you do not have a user account with permission to execute the command then it will fail with an unauthorized error.

      -p
      --password <password>

      Specifies the password of the user executing the command. If you do not have a user account with permission to execute the command then it will fail with an unauthorized error. If this argument is specified, but no password is given then the command will prompt the user for a password through non-echoed stdin. You may also specify your password by using the environment variable CB_REST_PASSWORD.

      --client-cert <path>

      The path to a client certificate used to authenticate when connecting to a cluster. May be supplied with --client-key as an alternative to the --username and --password flags. See the CERTIFICATE AUTHENTICATION section for more information.

      --client-cert-password <password>

      The password for the certificate provided to the --client-cert flag, when using this flag, the certificate/key pair is expected to be in the PKCS#12 format. See the CERTIFICATE AUTHENTICATION section for more information.

      --client-key <path>

      The path to the client private key whose public key is contained in the certificate provided to the --client-cert flag. May be supplied with --client-cert as an alternative to the --username and --password flags. See the CERTIFICATE AUTHENTICATION section for more information.

      --client-key-password <password>

      The password for the key provided to the --client-key flag, when using this flag, the key is expected to be in the PKCS#8 format. See the CERTIFICATE AUTHENTICATION section for more information.

      --import

      Import function(s) from a file. This option requires --file to be specified. The file provided should be from the --export option.

      --export

      Export a named function to a file. This option requires --file and --name to be specified.

      --export-all

      Export all functions to a file. This option requires --file to be specified.

      --delete

      Deletes a named function. Functions can only be deleted when in the undeployed state. This option requires --name to be specified.

      --list

      List all functions.

      --deploy

      Deploys the named function. This option requires --name to be specified, as well as --bucket and --scope for collection-aware functions.

      --undeploy

      Undeploys the named function. This option requires --name to be specified, as well as --bucket and --scope for collection-aware functions.

      --pause

      Pause the named function. This option requires --name to be specified, as well as --bucket and --scope for collection-aware functions. See the PAUSE VS UNDEPLOY section for more information.

      --resume

      Resume the named function. This option requires --name to be specified, as well as --bucket and --scope for collection-aware functions. See the PAUSE VS UNDEPLOY section for more information.

      --name <name>

      The name of the function to take a action against. This is used by --deploy, --undeploy, --pause, --resume and --delete options.

      --bucket <bucket>

      The bucket to which the function to take an action against belongs. This needs to be specified together with --scope or both should be omitted for collection-unaware functions. This is used by --deploy, --undeploy, --pause, --resume and --delete options.

      --scope <scope>

      The scope to which the function to take an action against belongs. This needs to be specified together with --bucket or both should be omitted for collection-unaware functions. This is used by --deploy, --undeploy, --pause, --resume and --delete options.

      --boundary <from-everything|from-now>

      (Deprecated) The place to start at when deploying a new function. Accepts 'from-now' or 'from-everything' defaulting to 'from-everything' if the --boundary flag is omitted.

      --file <file>

      The file to import and export functions to. This is used by --export and --import options only.

      HOST FORMATS

      When specifying a host for the couchbase-cli command the following formats are expected:

      • couchbase://<addr>

      • <addr>:<port>

      • http://<addr>:<port>

      It is recommended to use the couchbase://<addr> format for standard installations. The other two formats allow an option to take a port number which is needed for non-default installations where the admin port has been set up on a port other that 8091.

      CERTIFICATE AUTHENTICATION (MTLS AUTHENTICATION)

      This tool supports authenticating against a Couchbase Cluster by using certificate based authentication (mTLS authentication). To use certificate based authentication a certificate/key must be supplied, there a currently multiple ways this may be done.

      PEM ENCODED CERTIFICATE/KEY

      An unencrypted PEM encoded certificate/key may be supplied by using: - --client-cert <path> - --client-key <path>

      The file passed to --client-cert must contain the client certificate, and an optional chain required to authenticate the client certificate.

      The file passed to --client-key must contain at most one private key, the key can be in one of the following formats: - PKCS#1 - PKCS#8

      Currently, only the following key types are supported: - RSA - DSA

      PEM ENCODED CERTIFICATE/PEM OR DER ENCRYPTED PKCS#8 KEY

      An encrypted PKCS#8 formatted key may be provided using: - --client-cert <path> - --client-key <path> - --client-key-password <password>

      The file passed to --client-cert must contain the client certificate, and an optional chain required to authenticate the client certificate.

      Currently, only the following key types are supported: - RSA - DSA

      ENCRYPTED PKCS#12 CERTIFICATE/KEY

      An encrypted PKCS#12 certificate/key may be provided using: - --client-cert <path> - --client-cert-password <password>

      The file passed to --client-cert must contain the client certificate and exactly one private key. It may also contain the chain required to authenticate the client certificate.

      Currently, only the following key types are supported: - RSA - DSA

      EXAMPLES

      To import functions from a file called functions.json:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --import --file functions.json

      To export a function called alert_function to a file called functions.json:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --export --name alert_function --file functions.json

      To export all functions to a file called functions.json:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --export-all --file functions.json

      To list all functions:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --list

      To delete a function called alert_function:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --delete --name alert_function

      To deploy a function called alert_function and process both all historical data and new data:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --deploy --name alert_function --boundary from-everything

      To deploy a function called alert_function and process only new data:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --deploy --name alert_function --boundary from-now

      To undeploy a function called alert_function:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --undeploy --name alert_function

      To pause a function called alert_function:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --pause --name alert_function

      To resume a function called alert_function:

      $ couchbase-cli eventing-function-setup -c 192.168.1.5 -u Administrator \
       -p password --resume --name alert_function

      UNDEPLOY VS PAUSE

      Once you undeploy an eventing function you will have no opportunity to resume from the point at which the function was undeployed; this is not the case for pause/resume. Pausing an eventing function allows you to make changes to it or its settings while retaining the ability to continue from the point at which the function was paused.
