ECS task stops, container exits. Executable file not in $PATH - docker

Question

I have been trying to get my application working - but I keep getting an error:
Task Stop Reason: Essential container in task exited; Container myapp Status Reason: CannotStartContainerError: API error (400): OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"docker-compose up\": executable file not found in $PATH": unknown
My Dockerfile:
FROM node:9.10.0
COPY / /myapp
WORKDIR /myapp
RUN chown -R node:node /myapp
USER node
RUN mkdir /home/node/.npm-global
ENV PATH=/home/node/.npm-global/bin:$PATH
ENV NPM_CONFIG_PREFIX=/home/node/.npm-global
RUN npm install -g #angular/cli
RUN npm install
USER root
ENV USER root
RUN apt-get update && \
apt-get install -y \
python \
python-dev \
python-pip \
python-setuptools \
&& pip install --upgrade awscli \
&& apt-get clean
Now my task definition (deploy.yaml) is pretty simple and a part of it is:
....
task:
taskRole: "<role>"
containerDefinitions:
- command:
- "docker-compose up"
...
When deploying the app, ECS normally runs docker run I assume, while I need docker-compose up to start my services (in docker-compose.yaml). Where do I run this command, or how do I fix this path?

If you look closer to the error message :
starting container process caused "exec: \"docker-compose up\": executable file not found in $PATH": unknown
You notice that Docker is trying to find an executable named "docker-compose up" in PATH. This is probably incorrect,it should have looked for a "docker-compose" executable (note the missing "[space] up" in exe path).
This is probably caused by a wrong "-command" YML properties.
You should have something like :
...
-command :
-docker-compose
-up
I experienced the same problem with the ENTRYPOINT command in the Dockerfile :
ENTRYPOINT ["command with parameters"]
is invalid. You must have
ENTRYPOINT ["command", "with", "parameters"]
