Vertica Accelerator Command Line Client

The Vertica Accelerator Command Line Interface (VCLI) is an alternate client for managing Vertica Accelerator databases.

• Vertica Accelerator Command Line Client
  • Prerequisites
  • Installation
    • Installing the latest release
    • Installing from source
    • Autocomplete
  • Package release process
  • Post-install Configuration
  • Context-sensitive help
  • Maintainers

Prerequisites

• You must be customer or trial user of Vertica Accelerator with a valid account to use VCLI.
• You can contact the project maintainers or Vertica Accelerator support to obtain a "accelerator_client_id" which is needed in order to use the package

Installation

Installing the latest release

$ pip3 install vertica-accelerator-cli

or

$ python3 -m pip install dist/vertica-accelerator-cli-0.1.0.tar.gz --upgrade

Installing from source

$ pip3 install git+https://github.com/vertica/vertica-accelerator-cli.git@master

Autocomplete

To enable autocomplete for VCLI, install and configure argcomplete:

$ sudo python3 -m pip install argcomplete
$ sudo activate-global-python-argcomplete

Package release process

1. Create a virtual environment:

$ python3 -m venv env
$ source venv/bin/activate
$ export PYTHONPATH=.
$ mkdir ./python-packages/

2. Create the package:

$ python3 -m pip install --upgrade build
$ python3 -m build

Post-install Configuration

You can create profiles to manage multiple identities.

1. Run the interactive configuration to create a new profile called accelerator-profile:

$ va config --profile accelerator-profile

2. You must log in to a profile with va login --profile to execute VCLI commands. Logins expire in one hour. For help, run va login -h:

$ va login --profile accelerator-profile
Login success

3. Create a file ~/.vcli/credentials with the following format:

[default]
username = [e-mail]
password = example_password
client_id = example_client_id
auth_endpont = https://vertica.okta.com
access_token_file = sample_access_token

[accelerator-profile]
username = [e-mail]
password = accelerator-profile_password
client_id = accelerator_client_id
auth_endpont = https://vertica.okta.com
access_token_file = accelerator-profile_access_token

4. Create a file ~/.vcli/config with the following format:

[default]
service_endpoint = https://accelerator.vertica.com
max_attempts = 3

[vaas-test]
service_endpoint = https://accelerator.vertica.com
max_attempts = 3
verify_ssl=false

Context-sensitive help

For help, run va --help or va -h:

$ va --help
usage: va [-h] {config,login,logout,database,database-config,subcluster,backup,session,task,cron,report,dns}

• To view va database create options:

  $ va database create -h
  usage: va database create [-h] --name <value> --password <value> --nodes <value>
                                 --region <value> --availability_zone <value> 
                                 --instance_type <value> [--external_access_cidr_block <value>]
                                 [--vertica_version <value>] [--profile <value>]
  
  optional arguments:
    -h, --help            show this help message and exit
    --name <value>        The name of the database. The database name must consist of
                          1 to 18 alpha-numeric characters and start with a letter.
    --password <value>    The password for the database. The password must consist of
                          8 to 30 upper-case, lower-case, numeric, and special characters.
    --nodes <value>       The number of primary cluster nodes for the database. Valid values: [3, 6, 12]
    --region <value>      The region of the database. For example: 'us-east-1'
    --availability_zone <value>
                          The availability zone of the database. For example: 'us-east-1a'
    --instance_type <value>
                          The instance type of the database. 
                          Valid values: ['i3.2xlarge', 'i3.4xlarge', 'i3.8xlarge', 'i3.16xlarge']
    --external_access_cidr_block <value>
                          The IPv4 external access CIDR block(s) of the database, which acts as a whitelist
                          for a range of IP addresses that can access the database as a client. For example,
                          the CIDR block 192.0.2.0/24 allows clients to connect from 192.0.2.0 through 192.0.2.255.
                          Separate multiple CIDR blocks with a comma: 192.0.2.0/24,192.0.2.0/32
    --vertica_version <value>
                          The AMI version of the Vertica database. Valid values: ['10.1.0-1', '10.1.0-2', '11.0.0-1']
    --profile <value>     Use a specific profile from the credentials file (default path: "~/.vcli/credentials").
                          If you don't specify a profile, VCLI defaults to the 'default' profile when
                          communicating with Vertica Accelerator services.
