ERROR: Service 'search' failed to build: The command '/bin/sh -c ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.5.1/elasticsearch-analysis-ik-7.5.1.zip' returned a non-zero code: 1

原因是，安装分词器时候有一次键盘交互，需要键盘输入“y”

解决方式：

RUN sh -c '/bin/echo -e "y" | ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v${VERSION}/elasticsearch-analysis-ik-${VERSION}.zip'

Dockerfile:

FROM elasticsearch:7.5.1

ENV VERSION=7.5.1
# elasticsearch-analysis-ik
RUN sh -c '/bin/echo -e "y" | ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v${VERSION}/elasticsearch-analysis-ik-${VERSION}.zip'

Docker build 键盘命令交互
