backup-service-nodes-threads-map
Manage the backup service nodes threads map.
SYNOPSIS
couchbase-cli backup-service [--cluster <url>] [--username <user>] [--password <password>] [--client-cert <path>] [--client-cert-password <password>] [--client-key <path>] [--client-key-password <password>] [--output] nodes-threads [--get] [--set] [--add] [--node <node-uuid>] [--threads <threads>]
ACTION OPTIONS
- --get
-
Get the backup service’s nodes threads map.
- --set
-
Set a new backup service’s nodes threads map.
- --add
-
Add a new entry in the backup service’s nodes threads map.
HOST FORMATS
When specifying a host for the couchbase-cli command the following formats are expected:
-
couchbase://<addr>
orcouchbases://<addr>
-
http://<addr>:<port>
orhttps://<addr>:<port>
-
<addr>:<port>
It is recommended to use the couchbase://<addr> or couchbases://<addr> format for standard installations. The other 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 (or 18091 for https).
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 retrieve the backup service’s nodes threads map:
$ couchbase-cli backup-service -c 127.0.0.1:8091 -u Administrator -p asdasd \ nodes-threads --get Node UUID | Threads ------------------------------------------------- 23ec390488495fec2074119a61d2eb91 | 3 76dc6557ed98ac7e78e70cf0d28921f3 | 4
This will show you each backup service node’s UUID and the number of threads allocated to it.
To set the backup service’s nodes threads map:
$ couchbase-cli backup-service -c 127.0.0.0:8091 -u Administrator -p asdasd \ nodes-threads --set --node 23ec390488495fec2074119a61d2eb91 --threads 3 SUCCESS: Set node threads map
This will overwrite the map in the backup service with the number of threads
allocated to the backup service node with UUID
23ec390488495fec2074119a61d2eb91
to 3.
To add a new entry to the backup service’s nodes threads map:
$ couchbase-cli backup-service -c 127.0.0.1:8091 -u Administrator -p asdasd \ nodes-threads --add --node 76dc6557ed98ac7e78e70cf0d28921f3 --threads 4 SUCCESS: Updated node threads map
This will add a new entry to the backup service’s nodes threads map, allocating
4 threads to the backup service node with UUID
76dc6557ed98ac7e78e70cf0d28921f3
.
ENVIRONMENT AND CONFIGURATION VARIABLES
- CB_REST_USERNAME
-
Specifies the username to use when executing the command. This environment variable allows you to specify a default argument for the -u/--username argument on the command line.
- CB_REST_PASSWORD
-
Specifies the password of the user executing the command. This environment variable allows you to specify a default argument for the -p/--password argument on the command line. It also allows the user to ensure that their password are not cached in their command line history.
- CB_CLIENT_CERT
-
The path to a client certificate used to authenticate when connecting to a cluster. May be supplied with
CB_CLIENT_KEY
as an alternative to theCB_USERNAME
andCB_PASSWORD
variables. See the CERTIFICATE AUTHENTICATION section for more information. - CB_CLIENT_CERT_PASSWORD
-
The password for the certificate provided to the
CB_CLIENT_CERT
variable, when using this variable, the certificate/key pair is expected to be in the PKCS#12 format. See the CERTIFICATE AUTHENTICATION section for more information. - CB_CLIENT_KEY
-
The path to the client private key whose public key is contained in the certificate provided to the
CB_CLIENT_CERT
variable. May be supplied withCB_CLIENT_CERT
as an alternative to theCB_USERNAME
andCB_PASSWORD
variables. See the CERTIFICATE AUTHENTICATION section for more information. - CB_CLIENT_KEY_PASSWORD
-
The password for the key provided to the
CB_CLIENT_KEY
variable, when using this variable, the key is expected to be in the PKCS#8 format. See the CERTIFICATE AUTHENTICATION section for more information.
