如何在dockerized上安装自定义的REST插件

Question

我试图在我的OpenSearch上安装自定义REST插件.

我用的是ubuntu 20

这是我的docker-compose.yml文件

• 运行码头-编写启动服务并运行良好

但我不知道怎么继续下去..。

这是插件布局(我从这里克隆的)

当然，没有插件，码头映像就可以运行了:/因此，您需要在安装插件的情况下创建一个停靠映像。

打开插件项目外部的一个新目录，其中包含您的打包插件。这个包叫做->my-plugin.zip，位于build/distributions/my-plugin.zip下的插件项目中。如果它不在那里，那么您应该像这样组装插件：./gradlew assemble -Dopensearch.version=1.0.0 -Dbuild.snapshot=false

将以下Dockerfile添加到新目录：

FROM opensearchproject/opensearch:1.0.0
ADD ./my-plugin.zip /usr/
RUN /usr/share/opensearch/bin/opensearch-plugin install file:///usr/my-plugin.zip

ADD将将本地包添加到容器中，以便下一个命令可以使用它。RUN之后的脚本将将插件安装到OpenSearch中。

构建码头映像，添加一个标记将使以后的生活更加轻松：

docker build --tag=opensearch-with-my-plugin .

现在，您有一个开放搜索映像与您的插件安装在上面！

修复您最初发布的YAML文件，以便它使用正确的图像。这意味着将opensearchproject/opensearch:1.0.1替换为您生成的映像标记- opensearch-with-my-plugin。并将其添加到带有Dockerfile的目录中(在项目中不像您拥有的那样)。

我冒昧地将仪表板版本更改为1.0.0，因为我不确定它是否适用于图像的1.0.0。无论如何，这应该是一个坚实的开端！

通过在终端中运行此命令进行验证，并确保您的插件已安装：)

curl -XGET https://localhost:9200/_cat/plugins -u 'admin:admin' --insecure

此外，我还创建了一个包含更多信息的插件的GitHub模板。您克隆的回购是我在编写插件时为我的博客帖子创建的，所以它是一个REST插件，但不是最普通的插件。

如果您在运行过程中仍然有问题，请在评论中告诉我，我很乐意提供帮助。
