How to build and run

Take helloworld as an example java server

cd helloworld/dubbo/java-server
sh build.sh
cd ./target
tar -zxvf user-info-server-0.2.0-assembly.tar.gz
cd ./user-info-server-0.2.0
sh ./bin/server.sh start

java client

cd helloworld/dubbo/java-client
sh build.sh
cd ./target
tar -zxvf user-info-client-0.2.0-assembly.tar.gz
cd ./user-info-client-0.2.0
sh ./bin/server.sh start

go server

• $ARCH = [linux, mac, windows] and $ENV = [dev, release, test]

cd helloworld/dubbo/go-server
sh ./assembly/$ARCH/$ENV.sh
cd ./target/linux/user_info_server-0.3.1-20190517-0930-release
# $SUFFIX is a suffix of config file,
# such as server_zookeeper.yml when $SUFFIX is "zookeeper", 
# if $SUFFIX = "", default server.yml
sh ./bin/load.sh start $SUFFIX

go client

• $ARCH = [linux, mac, windows] and $ENV = [dev, release, test]

cd helloworld/dubbo/go-client
sh ./assembly/$ARCH/$ENV.sh
cd ./target/linux/user_info_client-0.3.1-20190517-0921-release
# $SUFFIX is a suffix of config file,
# such as client_zookeeper.yml when $SUFFIX = zookeeper", 
# if $SUFFIX = "", config file is client.yml
sh ./bin/load_user_info_client.sh start $SUFFIX

Configure Environment Variable

1. Add APP_LOG_CONF_FILE. eg: /home/xx/dubbogo-samples/helloworld/client/conf/log.yml
2. Add CONF_CONSUMER_FILE_PATH eg: /home/xx/dubbogo-samples/helloworld/client/conf/client.yml
3. Add CONF_PROVIDER_FILE_PATH eg: /home/xx/dubbogo-samples/helloworld/server/conf/server.yml

How to contribute

If you want to add some samples, we hope that you can do this:

1. Adding samples in appropriate directory. If you dont' know which directory you should put your samples into, you can get some advices from dubbo-go community.
2. You must run the samples locally and there must be no any error.
3. If your samples have some third party dependency, including another framework, we hope that you can provide some docs, script is better.
4. Please make pr to https://github.com/dubbogo/dubbo-samples instead of https://github.com/apache/dubbo-samples. We will synchronize to apache/dubbo-samples regularly.
