I have a docker Image with the following Entrypoint. 

ENTRYPOINT [ "sh", "-c", "/var/www/html/app/Console/cake schema update -y && /var/www/html/app/Console/cake migration && apache2-foreground"]

Now I want to use portainer.io to manage docker swarm. I created a new service to where I want to set the entrypoint (instead of in the Image). So I deleted the entrypoint In the dockerfile, and added it into "Image" > "Entrypoint". I added:

sh -c /var/www/html/app/Console/cake schema update -y && /var/www/html/app/Console/cake migration && apache2-foreground

However, the containers of the service are failing to start. Without the entrypoint, the containers are starting. Here is an example of the Dockerfile, where the Entrypoint is set.

#start with base Image from php
FROM php:7.3-apache

#install system dependencies and enable PHP modules

RUN apt-get update && apt-get install -y \
      libicu-dev \
      libpq-dev \

      unzip \

How do I have to set the Entrypoint? When I set it a portainer, it is later shown under the section CDM.

    The quoting in your two invocations is different; does that matter? Can you let it fall back to the entrypoint declared in the image? What actually happens when you launch it? – David Maze Aug 27 '19 at 14:00
  • I kept the entrypoint in the image definition and it is running fine. – DS87 Aug 28 '19 at 12:38
  • I just run into the same issue. Instead of creating a container in portainer directly, as a workaround I created a stack with one container only. That spins up the container and let me set the entrypoint however I like. – pnbecker Aug 29 '23 at 08:04
