Overview

kubectl-envsecret is a Kubernetes plugin designed to simplify the creation of Kubernetes secrets from .env files, including support for multiline environment variables. This tool streamlines the management of secrets, making it easier to handle configurations that include complex multiline values.

Features

• Create Kubernetes secrets from .env files.
• Support for multiline environment variables.
• Easy integration with kubectl as a plugin.

Installation

To install kubectl-envsecret, you need to have Go installed on your machine. You can then use the following command to install the plugin:

go install github.com/ogticrd/kubectl-envsecret@latest

Usage

Basic Usage

The primary command provided by kubectl-envsecret is create, which reads a .env file and creates a corresponding Kubernetes secret.

kubectl envsecret create --from-env-file <path-to-env-file> --from-env-file <path-to-other-files>

Command Options

• --from-env-file: Specifies the path(s) to the .env file. This option can be used multiple times to specify multiple .env files.

Examples

Create a Secret from a Single .env File

kubectl envsecret create --from-env-file /path/to/.env

Create a Secret from Multiple .env Files

kubectl envsecret create --from-env-file /path/to/.env --from-env-file /another/path/.env
