What is it?

This project is an elixir and phoenix docker environment. The following tools are installed:

• nodejs
• mix
• hex
• phx_new

Why should you use it?

First of all, it is helpful to run phoenix and installs dependencies avoiding conflicts with other phoenix projects. The second reason, it makes your local machine clean

How to use it?

After you clone the project, follow the steps:

• open a terminal session in your terminal tool (Iterm, Terminal, Putty)
• go to folder where you've clone the project (Ex.: cd docker-compose-for-elixir-and-phoenix)
• type the command: make run

This command will run the container and open a session inside the container. If all goes well, you will be in the path /usr/src/app. In this path, you can run commands like mix phx.new myfirst_phonenix_project

IMPORTANT!

when you run make runon the first time, the docker image will be created. In the next times, docker compose will use the image.

FAQ

=> I already have a exixir/phoenix project. How can I use this docker container? A: Pretty simple. Clone this docker container project and copy the files Dockerfile, docker-compose, entrypoint, Makefile, and paste them inside your elixir root path. After that, type the command: make run.

=> Why nodejs is required? It is worth noting nodejs is installed because phoenix use webpack for assets management (https://hexdocs.pm/phoenix/up_and_running.html). If you intend to do not use assets in your project, feel free to edit Dockerfile and remove nodejs \ and type make run. Reminder yourself to type make destroy and make run whether you already created docker image previously

=> I'm having problems to up the container or run rails project. What can I do ? A: create a github issue . I promise will answer as soon as possible
