Nacos is committed to help you discover, configure, and manage your microservices. It provides a set of simple and useful features enabling you to realize dynamic service discovery, service configuration, service metadata and traffic management.

Prerequisite

Install Nacos Standalone Mode Using Docker Compose

  1. Before setting everything else, create a directory for Nacos home mount. Ensure that the directory exists and appropriate permission have been granted.

    $ mkdir -vp ~/docker/nacos/{logs,init.d}
$ touch ~/docker/nacos/init.d/custom.properties

  2. Modify the ~/docker/nacos/init.d/custom.properties file according to your requirements.

    nacos.core.auth.enabled=false

  3. Modify the .env file, you can fine tune these configurations to meet your requirements.

    # common
NACOS_IMAGE=nacos/nacos-server:v2.1.1
NACOS_JVM_XMS=512m
NACOS_JVM_XMX=512m
NACOS_AUTH_ENABLE=false
NACOS_PREFER_HOST_MODE=hostname
NACOS_MYSQL_SERVICE_NETWORK=dev_mysql   # In MySQL replica mode, set it to dev_mysql_replica
NACOS_MYSQL_SERVICE_HOST=mysql          # In MySQL replica mode, mysql-replica-master
NACOS_MYSQL_SERVICE_PORT=3306
NACOS_MYSQL_SERVICE_USER=root
NACOS_MYSQL_SERVICE_PASSWORD=123456
NACOS_MYSQL_SERVICE_DB_NAME=nacos

# Nacos standalone mode
NACOS_HOME=~/docker/nacos
NACOS_PORT_8848=8848
NACOS_PORT_9848=9848
NACOS_PORT_9555=9555

  4. Make sure you are in the same directory as nacos.yml and start Nacos, Visit the Nacos URL http://host:8848/nacos, and log in with username nacos and the password nacos:

    $ docker-compose -f nacos.yml up -d
