如何将Elasticsearch模板与Docker映像捆绑在一起？

Question

我目前正在构建一个自定义docker映像以用于集成测试。我的要求是使用默认ingester管道和模板映射的自定义配置来设置它。

Dockerfile：

FROM docker.elastic.co/elasticsearch/elasticsearch:5.6.2
ADD config /usr/share/elasticsearch/config/
USER root
RUN chown -R elasticsearch:elasticsearch config
RUN chmod +x config/setup.sh
USER elasticsearch
RUN elasticsearch-plugin remove x-pack
EXPOSE 9200
EXPOSE 9300

其中 config 是包含以下内容的目录：

> elasticsearch.yml  for the configuration
> templates in the form of json files
> setup.sh - script which executes curl to es in order to register pipelines to _ingester and template mappings

设置脚本如下所示：

#!/bin/bash
# This script sets up the es5 docker instance with the correct pipelines and templates

baseUrl='127.0.0.1:9200'
contentType='Content-Type:application/json'


# filebeat
filebeatUrl=$baseUrl'/_ingest/pipeline/filebeat-pipeline?pretty'
filebeatPayload='@pipeline/filebeat-pipeline.json'

echo 'setting filebeat pipeline...'
filebeatResult=$(curl -XPUT $filebeatUrl -H$contentType -d$filebeatPayload)
echo -e "filebeat pipeline setup result: \n$filebeatResult"

# template
echo -e "\n\nsetting up templates..."
sleep 1

cd template
for f in *.json
do
    templateName="${f%.*}"
    templateUrl=$baseUrl'/_template/'$templateName

    echo -e "\ncreating index template for $templateName..."
    templateResult=$(curl -XPUT $templateUrl -H$contentType -d@$f)
    echo -e "$templateName result: $templateResult"
    sleep 1
done

echo -e "\n\n\nCompleted ES5 Setup, refer to logs for details"

在Elastic启动并运行后，如何以执行脚本的方式构建和运行映像？

我通常要做的是包括一个像您这样的较暖的脚本，并在开始时添加以下几行。我在Docker中没有其他方法可以等待基础服务启动

# wait until ES is up
until $(curl -o /dev/null -s --head --fail $baseUrl); do
    echo "Waiting for ES to start..."
    sleep 5
done
