1. Prerequisites
- A k8s cluster with three master nodes. The label names of these three nodes are etcd. The
IPs of the three master nodes are: 192.165.187.170, 192.165.187.171, 192.165.187.172 - A mysql database, the ip of the database is: 192.165.187.180 Username: root Password: 123456
2. Prepare the nacos database
Create a database with a nacos name in the mysql database, and then execute the following table creation statement
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

The namespace of the installation is in kube-system
k8s.kuboard.cn/role: etcd. Please note that this label must contain the three nodes you want to install.
- Installation method 1. kubectl installation:
After modifying the required yaml, put nacos.yaml on master1, enter the directory where it is located and execute:
kubectl apply -f nacos.yaml
The installation is successful
- Method 2: Install in kuboard
1. Enter the kube-system namespace of kuboard and click to import the workload.
Just follow the prompts step by step.
