具有请求的Docker Elasticsearch插件
我们正试图在Docker容器中运行Elasticsearch节点。 我们正在使用Search Guard插件来提高安全性。 但是，在安装过程中，插件要求我们运行脚本。 此脚本要求ElasticSearch在运行时可以在端口9300上访问。 是否有延迟脚本的最佳做法？ 在执行之前我们已经尝试了睡眠和RUN和CMD Dockerfile命令。
这是输出：
elasticsearch | Search Guard Admin v5 elasticsearch | Will connect to localhost:9300 elasticsearch | ERR: Seems there is no elasticsearch running on localhost:9300 - Will exit Dockerfile：
FROM docker.elastic.co/elasticsearch/elasticsearch:5.3.0 USER root RUN apk update \ && apk upgrade \ && apk add nano USER root # Add the ElasticSeach config ADD elasticsearch.yml /usr/share/elasticsearch/config/ RUN chown elasticsearch:elasticsearch /usr/share/elasticsearch/config/elasticsearch.yml # Add the truststore ADD keys/truststore.jks /usr/share/elasticsearch/config/ RUN chown elasticsearch:elasticsearch /usr/share/elasticsearch/config/truststore.jks # Create the node certs ADD gen-cert/ /usr/share/elasticsearch/gen-cert/ WORKDIR /usr/share/elasticsearch/gen-cert RUN ./gen_node_cert.sh 0 ######### ######### RUN cp node-keystore.jks /usr/share/elasticsearch/config/ # Prep for boot! WORKDIR /usr/share/elasticsearch/ USER elasticsearch RUN /usr/share/elasticsearch/bin/elasticsearch-plugin install -b com.floragunn:search-guard-5:5.3.0-11 RUN chmod +x -R /usr/share/elasticsearch/plugins/search-guard-5/tools/ # Run the security script on start CMD sleep 10 && /usr/share/elasticsearch/plugins/search-guard-5/tools/sgadmin.sh \ -cd /usr/share/elasticsearch/plugins/search-guard-5/sgconfig/ \ -cn SHU \ -ks /usr/share/elasticsearch/config/node-keystore.jks \ -kspass Chupacabra \ -ts /usr/share/elasticsearch/config/truststore.jks \ -tspass Chupacabra \ -nhnv
我们能够得到这个工作。 我们只需将脚本添加到Dockerfile末尾的CMD命令中，以便在ElasticSearch启动脚本之后运行。
看起来每个文件只能有一个命令，所以我们必须查看基本弹性图像（ ElasticSearch Docker GitHub ）并添加到它。
CMD [“/ bin / bash”，“bin / es-docker”，“search-guard / run-sgadmin.sh”]
