Bigtable-hello-j8 | ||
================= | ||
|
||
Moves the Bigtable Hello World application to Google App Engine Standard for Java 8. | ||
|
||
|
||
* [Java 8](http://www.oracle.com/technetwork/java/javase/downloads/index.html) | ||
* [Maven](https://maven.apache.org/download.cgi) (at least 3.3.9) | ||
* [Gradle](https://gradle.org) | ||
* [Google Cloud SDK](https://cloud.google.com/sdk/) (aka gcloud) | ||
|
||
Initialize the Google Cloud SDK using: | ||
|
||
gcloud init | ||
|
||
gcloud auth application-default login | ||
|
||
Then you need to [Create a Cloud Bigtable Instance](https://cloud.google.com/bigtable/docs/creating-instance) | ||
|
||
|
||
## Using Maven | ||
|
||
### Run Locally | ||
|
||
mvn -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID appengine:run | ||
|
||
### Deploy to App Engine Standard for Java 8 | ||
|
||
mvn -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID appengine:deploy | ||
|
||
### Run Integration Tests | ||
|
||
mvn -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID verify | ||
|
||
## Using Gradle | ||
|
||
### Run Locally | ||
|
||
gradle -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID appengineRun | ||
|
||
### Integration Tests & Deploy to App Engine Standard for Java 8 | ||
|
||
gradle -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID appengineDeploy | ||
|
||
As you add / modify the source code (`src/main/java/...`) it's very useful to add | ||
[unit testing](https://cloud.google.com/appengine/docs/java/tools/localunittesting) | ||
to (`src/main/test/...`). The following resources are quite useful: | ||
|
||
* [JUnit4](http://junit.org/junit4/) | ||
* [Mockito](http://mockito.org/) | ||
* [Truth](http://google.github.io/truth/) | ||
|
||
### When done | ||
|
||
Cloud Bigtable Instances should be [deleted](https://cloud.google.com/bigtable/docs/deleting-instance) | ||
when they are no longer being used as they use significant resources. |
