如何在 Stargate 容器中启动 CDC 代理？

Question

我正在尝试为 Datastax CDC 构建集成测试。我正在尝试按照 here 的说明创建运行 CDC Java agent 的容器化 Stargate 实例。我正在使用以下 docker 文件：

FROM stargateio/coordinator-4_0:v2

ENV CLUSTER_NAME="test"
ENV CLUSTER_VERSION="4.0"
ENV DEVELOPER_MODE="true"
ENV ENABLE_AUTH="true"

RUN (curl -L https://github.com/datastax/cdc-apache-cassandra/releases/download/v2.2.9/agent-c4-2.2.9-all.jar --output agent-c4-2.2.9-all.jar)
ENV JAVA_OPTS="$JAVA_OPTS -javaagent:agent-c4-2.2.9-all.jar"

我正在使用

JAVA_OPTS

因为

JVM_EXTRA_OPTS

似乎没有效果。 Stargate 将这些插入 start 命令。我收到这个错误：

我试过下载 Cassandra

.jar

文件并将它们添加到类路径（如 this question 中所述）无济于事。我该如何解决这个错误？

Answer 1

看起来我们以前没有尝试过，所以我们没有一个可以工作的例子给你看。

我们正在研究它，并将尝试在接下来的几天内让它发挥作用。一旦我有什么要报告的，我会发布更新。干杯！
