Docker === Love

Docker can do :allthethings:!

Docker Can Do Everything!*

Improve your process for:

Testing Dev Tools & Servers WITH VIRTUALLY ZERO risk of messing up dependencies on your PC
Testing your software
Makes you write more idempotent, modular code… (I’ll write how to actually realize this in a follow up)

There may seem like a huge volume of new stuff to learn, don’t let that stop you from getting started.

Notes

If you see a docker run command with either options -d or -it: _ -it or -i -t will run the configured command interactively _ -d will start the docker container as a ‘daemon’ aka background service.

EXAMPLES

nginx

# Note: using host-based, shared folders
#(shared folders are not possible with the VOLUME Dockerfile cmd)
sudo docker run --name web01 -d -p 8181:80 \
  -v $(NGINX_DIR)/etc:/etc/nginx \
  -v $(NGINX_DIR)/log:/var/log/nginx \
  -v $(NGINX_DIR)/www:/var/www/html \
  nginx:latest

## Local data, isolated within instance
sudo docker run --name web01 -d -p 8181:80 nginx:latest

# nodejs
sudo docker run --name nodejs01 -d -p 3300:3300 -p 4433:4433 nodejs:latest
