dbpack-samples

Simply, you can build the environment by running the make run command. then, you can test by

  • curl -XPOST http://localhost:13000/v1/order/create for transaction commit test, or
  • curl -XPOST http://localhost:13000/v1/order/create2 for transaction rollback test.

Then check whether the database data is consistent.
Alternatively, you can manually build the environment according to the following steps.

Step0: Clone dbpack and dbpack-samples

git clone git@github.com:cectc/dbpack.git
git clone git@github.com:cectc/dbpack-samples.git
cd dbpack-samples

Step1: Setup etcd, you can deploy etcd with docker.

docker run -d --name etcd-server \
    --publish 2379:2379 \
    --publish 2380:2380 \
    --env ALLOW_NONE_AUTHENTICATION=yes \
    --env ETCD_ADVERTISE_CLIENT_URLS=http://etcd-server:2379 \
    bitnami/etcd:latest

Step2: Setup mysql, initialize the database with the following sql script

./scripts/order.sql
./scripts/product.sql

Step3: run dbpack

vim ./configs/config-aggregation.yaml
# update distributed_transaction.etcd_config.endpoints

vim ./configs/config-product.yaml
# update data_source_cluster.dsn
# update distributed_transaction.etcd_config.endpoints

vim ./configs/config-order.yaml
# update data_source_cluster.dsn
# update distributed_transaction.etcd_config.endpoints

cd ../dbpack

make build-local

./dbpack start --config ../dbpack-samples/configs/config-aggregation.yaml

./dbpack start --config ../dbpack-samples/configs/config-product.yaml

./dbpack start --config ../dbpack-samples/configs/config-order.yaml

Step4: setup order_svc client

cd ../dbpack-samples/dotnet/
vim ./order_svc/appsettings.Development.json
# update ConnectionStrings.OrderDB

dotnet run

Step5: setup product_svc client

cd ../dbpack-samples/dotnet/
vim ./product_svc/appsettings.Development.json
# update ConnectionStrings.ProductDB

dotnet run

Step6: setup aggregation_svc client

cd ../dbpack-samples/dotnet/
vim ./aggregation_svc/Controllers/OrderController.cs
# update createSoUrl updateInventoryUrl

dotnet run

Step7: access and test

curl -XPOST http://localhost:13000/v1/order/create

Check whether the database data is consistent.
