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
