1. Pull the nacos image
docker pull nacos/nacos-server:v2.1.2
2. Copy the files in the nacos container to the host for mounting
2.1. Run nacos in stand-alone mode first
docker run -d --name nacos -p 8848:8848 -e MODE=standalone nacos/nacos-server:v2.1.2
Check the running process: docker logs -f nacos
ps: If the startup fails, the server memory may be too small. If you want to limit the memory size occupied by nacos, use the following statement
docker run --name nacos -e JVM_XMS=256m -e JVM_XMX=256m -e MODE=standalone -p 8848:8848 -d nacos/nacos-server:v2.1.2 You
can also modify the memory size of the container after installation:
docker stop nacos
docker update -m 256M --memory-swap 512M nacos-quick
docker start nacos
2.2. Copy the nacos file to the /app directory on the host
docker cp nacos:/home/nacos /usr/local
ps: The default storage location of nacos in docker is /home/nacos
2.3. Delete nacos container
docker rm -f nacos
3. Create nacos database
Find the mysql-schema.sql file under /usr/local/nacos/config, copy the content inside and run it in mysql, and then the data table will be automatically generated
4. Run nacos
4.1. Run nacos in stand-alone mode and use mysql to store information
docker run -d --name nacos \
-p 8848:8848 \
-p 9848:9848 \
-p 9849:9849 \
–restart always \
-v /usr/local/nacos/logs:/home/nacos/logs\
-; v /usr/local/nacos/data:/home/nacos/data \
-v /usr/local/nacos/config:/home/nacos/config \ -e
MODE=standalone \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_SERVICE_HOST =Default port ip \
-e MYSQL_SERVICE_PORT=3306 \
-e MYSQL_SERVICE_DB_NAME=nacos \
-e MYSQL_SERVICE_USER=root \
-e MYSQL_SERVICE_PASSWORD=default password \
nacos/nacos-server:v2.1.2
View the running process: docker logs -f nacos
4.2. Run nacos in cluster mode and use mysql to store information
nacos1
docker run -d --name nacos-cluster \
-p 8848:8848 \
-p 9848:9848 \
