How to run multiple lines command in docker compose?

Question

I am trying to make this run but it retrieves this error:

fscrawler           | sed: -e expression #2, char 31: unknown option to `s'

I'm trying to run this command:

command: >
  sh -c "sed -i -e "s/{ELASTIC_PASSWORD}/${ELASTIC_PASSWORD}/g" 
  -e "s/{ELASTICSEARCH_HOST}/${ELASTICSEARCH_HOST}/g" 
  -e "s/{FSCRAWLER_HOST}/${FSCRAWLER_HOST}/g" /root/.fscrawler/job1/_settings.yaml 
  && fscrawler job1 --restart --rest"

I've tried with simple quotes and many other options (backslashes at the end as well) but couldn't make it work.

Move the commands into entrypoint file and call the file in the command — Simon P

SOLUTION:

docker-compose.yml

entrypoint: /path/to/entrypoint.sh
environment:
  - ELASTIC_HOST=${ELASTIC_HOST}
  - ELASTIC_USER=${ELASTIC_USER}
  - ELASTIC_PASSWORD=${ELASTIC_PASSWORD}
  - FSCRAWLER_HOST=${FSCRAWLER_HOST}

Dockerfile FSCrawler

...
COPY /host/path/to/entrypoint.sh /docker/path/to/entrypoint.sh
RUN chmod u+x /entrypoint.sh

Entrypoint

#!/bin/bash

sed -i -e "s|{ELASTIC_USER}|${ELASTIC_USER}|g" \
-e "s|{ELASTIC_PASSWORD}|${ELASTIC_PASSWORD}|g" \
-e "s|{ELASTIC_HOST}|${ELASTIC_HOST}|g" \
-e "s|{FSCRAWLER_HOST}|${FSCRAWLER_HOST}|g" /root/.fscrawler/job1/_settings.yaml 

fscrawler job1 --restart --rest
