How to use docker to deploy dubbo project

1. First, use springboot to build a simple dubbo test program and introduce related dependencies

Writing a public interface API

Write a provider to implement UserSvice and expose the service

Write the provider configuration file

Writing a Consumer
Get user information by calling the provider's service and return

Consumer configuration file

Testing procedures completed

Start locally to see if the program can call the service to start Zookeeper normally

Start the provider first and then the consumer

Through the dubbo console, we can see that our service has been successfully registered.

By accessing the local, we can see that our service can be called normally and return information

2.Package the project and upload it to the server

Modify the configuration file and change the address of the registration center to the address of the server

Use Maven to package and write Dockerfile files

Upload the provider and consumer jar packages and the corresponding Dockerfile files to the server

3. Build the image

Pull the zookeeper image

docker pull zookeeper

Build the service provider image

Build a consumer image

View All Mirrors

Add Alibaba Cloud security group

Start the zookeeper image, provider, and consumer in sequence
Here we start by sharing the network with the host, –net = host
Because our test service is very simple, we can start it directly using --net = host mode without configuring the network. Containers can communicate with each other or we can start it using port mapping:

docker run -d -p 2181:2181 --name zk01 zookeeper

View all started containers

test:

Open the browser and enter the server's IP address to access the service through our server's address:

Successfully return information, then our service deployment is complete
