dex

Starts docker-sync and docker-compose in background if not running yet and exec your command with dex command

What

It:

• Checks if docker-sync and docker-compose is running
• If yes it execute command in docker exec (which is much faster than docker-compose exec)
• If not it starts docker-sync in background and docker-compose up in background

Why

• It is easier to write dru mix test than docker-compose exec app mix test
• It is annoying to always manually run docker-sync-stack start in separated console.
• It is annoying to have separate console just for docker-sync
• Because docker-sync 0.2.0 introduced background mode

Install

If you don't have docker-sync 0.2 install it with script below. Make sure you are using system RVM if you use RVM.

git clone -b release/0.2.0 https://github.com/EugenMayer/docker-sync
cd docker-sync
sudo ./deploy_locally.sh

Run this to add dex to your /usr/local/bin

sudo ./install.sh

Usage

Setup your project

First setup default service name (as you have in docker-compose.yml) with

echo service-name > .docker-compose-default-service

It assumes that your default service when started with docker-compose up runs indefinite process. For development we recommend to set command value to sleep infinity that keeps the container up, but doesn't do anything other than when you run commands using dex:

Example docker-compose.yml (or your dev override file):

...
  myapp:
    command: sleep infinity
...

Execute commands like local

Execute your container command

dex command

Stop docker-compose and docker-sync

dex --stop

Why "dex"?
