gitlab上clone项目代码时遇到的坑：

RUN git config --global http.postBuffer 1048576000
RUN git clone -b meiling-yancheng-tuning https://gitlab-ci-token:xxxxxx@139.196.139.224/gaojingqi/dojoyn.git

有关缓冲区设置的问题，太小的话项目拷不下来，远端hang up
这个token是项目的token。

我的一些启动jar包命令

启动lookService

java -Xmx1000m -Xms1000m -cp assembly/target/assembly-0.0.1-ALPHA-SNAPSHOT.jar:experimental/target/experimental-0.0.1-ALPHA-SNAPSHOT.jar:meiling-spec/target/meiling-spec-0.0.1-ALPHA-SNAPSHOT.jar cn.enncloud.dojoyn.experimental.LookupService --enable_metrics --namespace defaultNamespace --opentsdb_host 10.19.132.135 --opentsdb_port 30044

启动mockClient

java -cp assembly/target/assembly-0.0.1-ALPHA-SNAPSHOT.jar:experimental/target/experimental-0.0.1-ALPHA-SNAPSHOT.jar:lookup-service/target/lookup-service-0.0.1-ALPHA-SNAPSHOT.jar cn.enncloud.dojoyn.experimental.MockEntrypoint --LookupMockClientNum 5 --enable_metrics --namespace defaultNamespace --opentsdb_host localhost --opentsdb_port 4242

带参数启动 mockclient

java -cp assembly/target/assembly-0.0.1-ALPHA-SNAPSHOT.jar:experimental/target/experimental-0.0.1-ALPHA-SNAPSHOT.jar:lookup-service/target/lookup-service-0.0.1-ALPHA-SNAPSHOT.jar cn.enncloud.dojoyn.experimental.MockEntrypoint --lookup_mock_client_num 20 --enable_metrics --namespace defaultNamespace --opentsdb_host 10.19.132.135 --opentsdb_port 30044

带port参数启动mock

java -Xmx1000m -Xms1000m -cp assembly/target/assembly-0.0.1-ALPHA-SNAPSHOT.jar:experimental/target/experimental-0.0.1-ALPHA-SNAPSHOT.jar:lookup-service/target/lookup-service-0.0.1-ALPHA-SNAPSHOT.jar cn.enncloud.dojoyn.experimental.MockEntrypoint --lookup_batch_data_size 50 --lookup_batch_timeout 10 --lookup_mock_client_num 20 --enable_metrics --namespace defaultNamespace --opentsdb_host 10.19.132.135 --opentsdb_port 30044 --lookup_service_grpc_host 10.19.132.135 --lookup_service_grpc_port 50051

一些常用命令

ssh root@10.19.132.182
apt-get install sysstat
docker tag arylookupmock:1.1 10.19.132.184:30100/library/arymock
ps -ef |grep docker
kubectl –namespace=ary exec -it ary-lookup-client-rc-0gwsl bash
