This document describes how to convert certificate files in Kubeconfig to certificate data.
Prerequisites
You must activate the CODING DevOps service for your Tencent Cloud account before you can use Coding Continuous Deployment (CD).

2. On the Workspace homepage, click 
Feature Overview
When adding a Kubernetes cloud account, you can select Kubeconfig or Service Account authentication method:
For authentication using Kubeconfig certificate files (in the example below,
certificate-authority, client-certificate, and client-key are all specific files that contain certificate information), you need to convert the certificate files to base64-encoded strings before adding a cloud account.apiVersion: v1kind: Configclusters:- cluster:certificate-authority: */ca.crtserver: https://******name: democontexts:- context:cluster: demouser: demoname: democurrent-context: demopreferences: {}users:- name: demouser:client-certificate: */client.crtclient-key: */client.key
The section below explains how to perform the conversion.
Get the base64-encoded string of the certificate file
Run the following commands:
OS X
cat "certificate file" | base64
Linux
cat "certificate file" | base64
Windows
certutil -f -encode "certificate file" "output file"
Update Kubeconfig file
1. Change
certificate-authority to certificate-authority-data, and enter the base64-encoded string of the */ca.crt certificate file.2. Change
client-certificate to client-certificate-data, and enter the base64-encoded string of the */client.crt certificate file.3. Change
client-key to client-key-data, and enter the base64-encoded string of the */client.key certificate file.The result is as follows:
