- What is Docker and why should I care about it?
- Historically: dev !== staging !== production
- Software, all of its dependencies and everything it needs to run
- Shares kernel with host operating system (faster to start)
- What are some of the Docker basics?
- Images and containers
- Pulling an image (
docker pull OPIONS IMAGE) - Running a container (
docker run OPIONS IMAGE) - Running detached (
-d) - Exposing ports (
-p HOST:CONTAINER) - Adding a volume (
-v ./app:/usr/share/nginx/html:ro) - Deleting containers (
docker rm CONTAINER) automatically (run --rm) - Create a simple
Dockerfile
- How do I set up a dev environment?
- Bind volume mappings
- docker-compose to simplify using Docker (
docker-compose up)
- Where should I go to learn more?
