将Solr Index从现有Docker容器复制到新的Docker Image中

时间：2018-02-08 23:09:27

标签： docker solr

这是我的设置。我使用docker创建了一个基本的solr容器（来自官方solr docker hub的5.5.5版）。在这个容器中，我创建了大约30000个文档。我现在要做的是创建一个新的docker solr图像，默认情况下包含这些文档。

我以为我可以将索引从现有容器中复制出来，然后通过dockerfile将其复制到我的新映像中。我通过复制它来尝试这个。

docker cp my_solr_container:/opt/solr/server/solr/core_name/data .

然后在我的新solr映像的Dockerfile中将此数据文件夹复制到相应的文件夹中     COPY --chown = solr：solr data / opt / solr / server / solr / core_name / data /

但是当我构建图像并尝试运行它时，我收到以下错误：

我还试图通过点击网址

以另一种方式复制索引 
http://host:8080/solr/replication?command=backup&location=/home/backup

在我现有的容器上，然后从容器中复制备份索引并以相同的方式复制到我的新docker镜像，但遇到了同样的错误。

从现有容器中复制数据的可行方法是什么，以便我可以使用已设置的数据构建新图像。

这是我的Dockerfile供参考：

FROM solr:5.5.5

ARG core_name="Development"
ARG core_path="/opt/solr/server/solr/dev"

COPY --chown=solr:solr schema.xml $core_path/conf/
COPY --chown=solr:solr solrconfig.xml $core_path/conf/
COPY --chown=solr:solr stopwords.txt $core_path/conf/

COPY --chown=solr:solr data $core_path/data/



USER solr
RUN echo "name=$core_name" > $core_path/core.properties

您可以使用[docker commit][1]将您创建文档的容器实例提交为新图像。
