如何通过docker-compose.yml中多行环境变量

Question

我正在尝试转换此 docker run命令：

docker run -it --rm --name logstash --net test opensearchproject/logstash-oss-with-opensearch-output-plugin:7.16.2 -e 'input { stdin { } } output {
 opensearch {
   hosts => ["https://opensearch:9200"]
   index => "opensearch-logstash-docker-%{+YYYY.MM.dd}"
   user => "admin"
   password => "admin"
   ssl => true
   ssl_certificate_verification => false
   }
}'

到docker-compose.yml文件。但是，我不知道如何定义上面传递的环境配置。关于如何将无名的多行环变量传递给码头组合的任何建议吗？

我尝试了多种YAML多行格式，但我不断获得：

错误：环境变量名称'input {stdin {}} output {openSearch {hosts'可能不会 包含空格。

docker-compose.yml：

version: '3'

services:
  logstash-producer:
    image: opensearchproject/logstash-oss-with-opensearch-output-plugin:7.16.2
    container_name: logstash-producer
    environment:
      - 'input { stdin { } } output {
          opensearch {
            hosts => ["https://opensearch:9200"]
            index => "opensearch-logstash-docker-%{+YYYY.MM.dd}"
            user => "admin"
            password => "admin"
            ssl => true
            ssl_certificate_verification => false
          }
        }'

由于-e位是在图像名称之后出现的，因此它是容器的命令。

我从来没有这样做，也无法测试它，但是

version: '3'

services:
  logstash-producer:
    image: opensearchproject/logstash-oss-with-opensearch-output-plugin:7.16.2
    container_name: logstash-producer
    command: |
        -e 'input { stdin { } } output {
        opensearch {
          hosts => ["https://opensearch:9200"]
          index => "opensearch-logstash-docker-%{+YYYY.MM.dd}"
          user => "admin"
          password => "admin"
          ssl => true
          ssl_certificate_verification => false
        }
      }'

如果那不起作用，请尝试将命令全部放在一行上。
