maven:

<dependency>
    <groupId>io.github.jxnu-liguobin</groupId>
    <artifactId>testcontainers-nebula_2.13</artifactId>
    <version>'latest version'</version>
    <scope>test</scope>
</dependency>

Usage Instructions

Java example: SimpleNebulaCluster

ZIO example: NebulaSpec

The zio module provides default configurations for better integration with zio-nebula, just adding dependency:

"io.github.jxnu-liguobin" %% "testcontainers-nebula-zio" % 'latest version'
// testcontainers-nebula-zio depends on zio-nebula dependency 
"io.github.jxnu-liguobin" %% "zio-nebula" % 'latest version'

Details:

1. NebulaSimpleClusterContainer.scala creates four container instances: graphd,metad,storaged,console.
2. NebulaClusterContainer.scala provides a generic definition, and any number of clusters can be created by implementing its abstraction methods, ports and volumes can be modified.
