Tembo CLI

Tembo CLI allows users to experience Tembo locally, as well as, manage and deploy to Tembo Cloud. It abstracts away complexities of configuring, managing, and running Postgres.

Getting Started

Installing CLI

Using homebrew

brew tap tembo-io/tembo
brew install tembo-cli

Using cargo

cargo install tembo-cli

Commands

Discover a wide range of commands and subcommands, along with their respective options, by exploring our comprehensive Command Reference.

Developing Tembo CLI

Local Testing

Clone this repo and run:

cargo install --path .

If the install path is in your shell path, you can then run tembo help and other tembo commands.

You can run this command to use the local code for any tembo command during development:

alias tembo='cargo run --'

Generating Rust Client from API

OpenAPI Generator tool is used to generate Rust Client.

Install OpenAPI Generator if not already by following steps here

Data plane API client

Go to tembodataclient directory in your terminal.

Delete the contents of the directory first and then run following command to re-generate the rust client code for the API.

openapi-generator generate -i https://api.data-1.use1.tembo.io/api-docs/openapi.json  -g rust -o . --additional-properties=packageName=tembodataclient

• Go to tembodataclient/src/lib.rs & add following line at the top to disable clippy for the generated code

#![allow(clippy::all)]

Control plane API client

Go to tembo_api_client directory in your terminal.

Delete the contents of the directory first and then run following command to re-generate the rust client code for the API.

openapi-generator generate -i https://api.tembo.io/api-docs/openapi.json  -g rust -o . --additional-properties=packageName=tembo_api_client

• Go to tembo_api_client/src/lib.rs & add following line at the top to disable clippy for the generated code

#![allow(clippy::all)]

• Create tembo_api_client/src/models/impls.rs file & add following code to it:

use std::str::FromStr;

use super::{Cpu, Environment, Memory, StackType, Storage};

impl FromStr for Cpu {
    type Err = ();

    fn from_str(input: &str) -> core::result::Result<Cpu, Self::Err> {

            "500Gi" => Ok(Self::Variant500Gi),
            _ => Err(()),
        }
    }
}

impl FromStr for StackType {
    type Err = ();

    fn from_str(input: &str) -> core::result::Result<StackType, Self::Err> {
        match input {
            "Analytics" => Ok(StackType::Analytics),
            "Geospatial" => Ok(StackType::Geospatial),
            "MachineLearning" => Ok(StackType::MachineLearning),
            "MessageQueue" => Ok(StackType::MessageQueue),
            "MongoAlternative" => Ok(StackType::MongoAlternative),
            "OLTP" => Ok(StackType::OLTP),
            "ParadeDB" => Ok(StackType::ParadeDB),
