Start Aerospike Graph Service

Start the Docker containers.

From the repository root, start AGS and Aerospike Database:

docker compose up -d

[+] Running 3/3
 ✔ Network asgraph_net                     Created
 ✔ Container aerospike-db                  Started
 ✔ Container aerospike-graph-service       Started
 ✔ Container asgraph-zipkin                Started

Example response

Wait for services to be ready.

AGS waits for the database to complete startup before accepting connections. This typically takes 10 to 20 seconds.

Check the AGS logs.

docker logs aerospike-graph-service
