This project contains a Docker image meant to facilitate the deployment of Nacos.
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.
NACOS_AUTH_IDENTITY_KEYNACOS_AUTH_IDENTITY_VALUENACOS_AUTH_TOKEN
- build:Nacos makes the source code of the docker image
- env: Environment variable file for compose yaml
- example: Docker compose example for Nacos server
- 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.
docker run --name nacos-quick -e MODE=standalone -p 8848:8848 -p 9848:9848 -d nacos/nacos-server:v2.2.0

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
