docker – creating and starting container, differences between API and CLI

I want to create a (named) container through the API without starting it (otherwise I would have to manually stop it immediately, not very clean), and use systemd to manage it as a service, but I’m a bit confused between the CLI and the API involved… In the API, some parameters for the container are […]

Docker PHP / Apache Container – Sendmail 553 Error “Domain of Sender Address does not exist” when trying to send mail

I’m having trouble sending e-mail on my PHP/Apache docker container via sendmail. I’m wondering if someone has a simple, straight forward solution.

Docker best practice on base images and host os

PHP websites with Docker

Initially I was setting the rabbitmq config file like this (Dockerfile): RUN echo “[{rabbit, [{loopback_users, []}]}].” > /etc/rabbitmq/rabbitmq.config But now I need to configure the shovel plugin and would like to use an actual config file from source. To start out simple, the config file only contains the loopback_users setting. Here’s the Dockerfile statements: ENV […]
