Last years approach in developing and delivering software to the customer is so popular Docker. Docker allows us to lock our software in some box in some environment and that environment is static and called - container. It means that there is already configured all what is required for our software. This is very good situation, because you don't have make huge installation instruction for your client or customers. In this article I will show you how to build Docker container and start there Symfony 5.0 application.
Lets get it done, but what we should start from?
We will start from installation Docker on your workstation to be able work with containers.
My example is based on Ubuntu 18.04 workstation. So first lets install docker running command in terminal: sudo apt-get install docker
The next step is to install docker-compose. As for me installation worked without following official instructions from here https://docs.docker.com/compose/install/ It was enough to type sudo apt-get install docker-compose sudo apt install python3-pip sudo pip3 install docker-compose on Ubuntu 18.04 terminal and it was installed.
To verify if docker-composer installed and proper version - type: docker-compose --version
I've got this: docker-compose version 1.17.1, build unknown
Environment is ready, so whats next!?
I will omit questions about configuring new project in IDE and etc. Now it is time to build your Dockerfile. What is Dockerfile? So it is special file that allow you using docker instructions build proper environment and run the project. My Dockerfile instructions looks like this:
FROM ubuntu:18.04
ENV TZ 'Europe/Warsaw'

RUN echo $TZ > /etc/timezone && \
apt-get update && apt-get install -y tzdata && \
rm /etc/localtime && \

apt-get clean
