nacos-docker's Introduction

Nacos Docker

Docker Pulls

This project contains a Docker image meant to facilitate the deployment of Nacos.

中文

Note

The following environment variables have been removed from the default values in the new version(Nacos 2.2.1) for the sake of system security, please add them yourself when starting up, otherwise an error will be reported at startup.

  1. NACOS_AUTH_IDENTITY_KEY
  2. NACOS_AUTH_IDENTITY_VALUE
  3. NACOS_AUTH_TOKEN

Project directory

  • build：Nacos makes the source code of the docker image
  • env: Environment variable file for compose yaml
  • example: Docker compose example for Nacos server

Precautions

  • The database master-slave image has been removed, after the latest nacos/nacos-server:latest image. For specific reasons, refer to Removing the Master-Slave Image Configuration
  • Since Nacos 1.3.1 version, the database storage has been upgraded to 8.0, and it is backward compatible
  • If you use a custom database, you need to initialize the database script yourself for the first time.

Quick Start

docker run --name nacos-quick -e MODE=standalone -p 8848:8848 -p 9848:9848 -d nacos/nacos-server:v2.2.0

Advanced Usage

  • Tips: You can change the version of the Nacos image in the compose file from the following configuration. example/.env
NACOS_VERSION=v2.2.0

Run the following command：

  • Clone project

    git clone --depth 1 https://github.com/nacos-group/nacos-docker.git
cd nacos-docker

  • Standalone Derby

    docker-compose -f example/standalone-derby.yaml up

  • Standalone Mysql

    # Using mysql 5.7
docker-compose -f example/standalone-mysql-5.7.yaml up

# Using mysql 8
docker-compose -f example/standalone-mysql-8.yaml up

  • Standalone Nacos Cluster

    docker-compose -f example/cluster-hostname.yaml up

  • Service registration

    curl -X POST 'http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=nacos.naming.serviceName&ip=20.18.7.10&port=8080'

  • Service discovery

    curl -X GET 'http://127.0.0.1:8848/nacos/v1/ns/instance/list?serviceName=nacos.naming.serviceName'

  • Publish config

    curl -X POST "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test&content=helloWorld"

  • Get config

      curl -X GET "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test"

  • Open the Nacos console in your browser

    link：http://127.0.0.1:8848/nacos/

Common property configuration

name description option
MODE cluster/standalone cluster/standalone default cluster
NACOS_SERVERS nacos cluster address eg. ip1:port1 ip2:port2 ip3:port3
PREFER_HOST_MODE Whether hostname are supported hostname/ip default ip

MYSQL_SERVICE_USER username of database
MYSQL_SERVICE_PASSWORD password of database
MYSQL_DATABASE_NUM It indicates the number of database default :1
MYSQL_SERVICE_DB_PARAM Database url parameter default :characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false
JVM_XMS -Xms default :1g
JVM_XMX -Xmx default :1g
JVM_XMN -Xmn default :512m
JVM_MS -XX:MetaspaceSize default :128m
JVM_MMS -XX:MaxMetaspaceSize default :320m
NACOS_DEBUG enable remote debug y/n default :n
TOMCAT_ACCESSLOG_ENABLED server.tomcat.accesslog.enabled default :false
NACOS_AUTH_SYSTEM_TYPE The auth system to use, currently only 'nacos' is supported default :nacos
NACOS_AUTH_ENABLE If turn on auth system default :false
NACOS_AUTH_TOKEN_EXPIRE_SECONDS The token expiration in seconds default :18000
NACOS_AUTH_TOKEN Note: It is removed from Nacos 2.2.1
NACOS_AUTH_CACHE_ENABLE Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay. default : false
MEMBER_LIST Set the cluster list with a configuration file or command-line argument eg:192.168.16.101:8847?raft_port=8807,192.168.16.101?raft_port=8808,192.168.16.101:8849?raft_port=8809
EMBEDDED_STORAGE Use embedded storage in cluster mode without mysql embedded default : none
NACOS_AUTH_CACHE_ENABLE nacos.core.auth.caching.enabled default : false
NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE nacos.core.auth.enable.userAgentAuthWhite default : false
NACOS_AUTH_IDENTITY_KEY nacos.core.auth.server.identity.key Note: It is removed from Nacos 2.2.1
NACOS_AUTH_IDENTITY_VALUE nacos.core.auth.server.identity.value Note: It is removed from Nacos 2.2.1
NACOS_SECURITY_IGNORE_URLS nacos.security.ignore.urls default : /,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**
NACOS_CONSOLE_UI_ENABLED nacos.console.ui.enabled default : true
NACOS_CORE_PARAM_CHECK_ENABLED nacos.core.param.check.enabled default : true
DB_POOL_CONNECTION_TIMEOUT Database connection pool timeout in milliseconds default : 30000

Advanced configuration

If the above property configuration list does not meet your requirements, you can mount the custom.properties file into the /home/nacos/init.d/ directory of the container, where the spring properties can be configured, and the priority is higher than application.properties file

If you have a lot of custom configuration needs, It is highly recommended to mount application.properties in production environment.

For example:

docker-compose -f example/custom-application-config.yaml up -d

Nacos + Grafana + Prometheus

Usage reference：Nacos monitor-guide

Note: When Grafana creates a new data source, the data source address must be http://prometheus:9090

请问是否nacos 支持mysql8.x以上版本，该如何部署

docker compose以standalone模式启动，nacos版本号一直显示为0.7.0

无论docker的image选择0.9.0，或者1.0.0-RC1，通过浏览器访问，NACOS的版本号一直显示为0.7.0。

nacos

  nacos:
    image: nacos/nacos-server:0.9.0

    hostname: nacos

建议改一下quick start

quick start 步骤太长，里面那些prometheus、grafana没必要启动，用户来了只是为了尝试nacos。
直接一条docker命令启动，如果-e是默认的能省略更好。
docker run -d -p 8848:8848 -e "PREFER_HOST_MODE=hostname" -e "MODE=standalone" nacos/nacos-server

docker-compose 创建有　nacos 　有一个应用没能启用。
是不是我的电脑内存不够吗。

windows 10环境下用powershell执行，出错了

docker 部署nacos

本地跑nacos 和config 是没问题的，docker 部署了nacos config就不起作用了，是不是要配置其他东西？

new dockerfile

做了一个基于alpine,zulu JDK11,mysql8.0的dockerfile
方便合进来么？

mysql变量要统一

我觉得mysql变量分mysql-common.env，mysql-master.env, mysql-slave.env有点分散了。统一成一个是不是好点,当然这个也是轻微建议。目前这个版本的nacos应用默认缺失下面几个变量,导致nacos默认启动不起来
MYSQL_MASTER_SERVICE_HOST=mysql-master
MYSQL_SLAVE_SERVICE_HOST=mysql-slave
MYSQL_MASTER_SERVICE_DB_NAME=nacos_devtest
MYSQL_MASTER_SERVICE_USER=nacos
MYSQL_MASTER_SERVICE_PASSWORD=nacos
下面变量的配置。
我觉得应用也统一用上上面的mysql变量会好点。一个地方配，几个地方用

仓库很大，建议精简

我看到master 分之其实就是几个配置文件，但下载半天,发现是第一个版本有一个jar造成的，rebase下？这样下载会快很多

镜像环境变量及启动脚本设计缺陷

1、这是最新的docker镜像内部的application.properties文件，可以看到以下问题：

server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos
server.port=${NACOS_SERVER_PORT:8848}
spring.datasource.platform=${SPRING_DATASOURCE_PLATFORM:""}
nacos.cmdb.dumpTaskInterval=3600
nacos.cmdb.eventTaskInterval=10
nacos.cmdb.labelTaskInterval=300
nacos.cmdb.loadDataAtStart=false
db.num=2
db.url.0=jdbc:mysql://${MYSQL_MASTER_SERVICE_HOST}:${MYSQL_MASTER_SERVICE_PORT:3306}/${MYSQL_MASTER_SERVICE_DB_NAME}?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.url.1=jdbc:mysql://${MYSQL_SLAVE_SERVICE_HOST}:${MYSQL_SLAVE_SERVICE_PORT:3306}/${MYSQL_MASTER_SERVICE_DB_NAME}?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=${MYSQL_MASTER_SERVICE_USER}
db.password=${MYSQL_MASTER_SERVICE_PASSWORD}
  • 必须填写MASTER和SLAVE两个数据源信息，num数量不可修改，虽然可以通过两个数据源地址一致实现启动，但是设计不太合理；
  • SLAVE只有 HOST 和 PORT参数，默认设计是 MASTER 和 SLAVE 是同用户和同密码吗？如果是的话，那这db.user和db.password的key应该 MYSQL_SERVICE_USER，而不应该加上_MASTER_？

2、docker 启动脚本存在设计缺陷，启动后会卡住当前 ssh session ,control + c也没办法退出，只能关闭当前session重新打开

How to config Nacos client not registered intranet ip？

I have deployed spring cloud project with docker, and registered to Nacos.
And i see the nacos service list -> myproject -> it's seems that registered the docker intranet ip , not the host-machine ip

can someone give some method to resolve this problem ? thank you.

集群版nacos的内存占用怎么调整

3个nacos实例+2个mysql实例+监控，总体来看占内存有点大,单是nacos就6G内存. 是否可以把内存配置抽成变量

当然不希望自己修改脚本重新打镜像。

docker集群版按照步骤来跑不起来

image

临时买了台阿里的ECS，执行命令：docker-compose -f example/cluster-hostname.yaml up
启动时： Access denied for user 用户访问被拒绝。
貌似没跑起来。
