docker -v
docker run hello-world

• Use the reference documentation to install a Java Development Kit
• Validate your installation with

java -version

• Use the reference documentation to install Apache Maven

The element below have been extracted from Stargate documentation

Download Stargate docker image :

docker pull stargateio/stargate-3_11:v1.0.41

docker run --name stargate \
  -p 8080:8080 \
  -p 8081:8081 \
  -p 8082:8082 \
  -p 8090:8090 \
  -p 127.0.0.1:9042:9042 \
  -d \
  -e CLUSTER_NAME=stargate \
  -e CLUSTER_VERSION=3.11 \
  -e DEVELOPER_MODE=true \
  stargateio/stargate-3_11:v1.0.41

With Development mode Stargate also the role of a data node, you do not need an extra Cassandra container.

All apis are enabled, here is the port list:

• 8080 is the graphql port
• 8081 is the authentication port
• 8082 is the rest port
• 8090 is the grpc port

After 30 seconds you should be able to following URLs:

• URL for health: http://localhost:8082/health
• URL for Open Api specification: http://localhost:8082/swagger-ui/#/
• URL for graphql Playground: http://localhost:8080/playground

You can now run the example

mvn install exec:java -Dexec.mainClass=com.datastax.tutorial.ConnectStargate

Expected output

[INFO] 
[INFO] --- exec-maven-plugin:3.0.0:java (default-cli) @ grpc-java ---
Keyspace 'test' has been created.
Table 'users' has been created.
2 rows have been inserted in table users.
FirstName=Doug, lastname=Wettlaufer
FirstName=Lorina, lastname=Poland
Everything worked!

You will need an Astra Database with an Astra Token

In class ConnectAstra edit the following properties

private static final String ASTRA_DB_ID      = "<id>";
private static final String ASTRA_DB_REGION  = "<region>";
private static final String ASTRA_TOKEN      = "<token>";
private static final String ASTRA_KEYSPACE   = "<keyspace>";

Then execute the class

mvn install exec:java -Dexec.mainClass=com.datastax.tutorial.ConnectAstra
