Docker practice application that counts page visits with Express, NodeJS, and Redis
The standard docker CLI does not allow developers to easily manage multiple containers and allow them to connect to each other. Docker Compose enables us to easily create a network of containers which will automatically allow network connections to each other.
docker-compose up
Pulls, builds and runs the listed services from docker-compose.yml.
docker-compose up --build
Similar to docker-compose up however this command rebuilds the containers if changes were made.
docker-compose up -d
Similar to docker-composer up however this command runs in the background allowing our terminal to remain free for executing other commands.
docker-compose down
Shuts down all running containers within the current project directory.
By default, docker-compose does not automatically restart containers if for any reason they crash. For example, forcing our node-app to exit with status of 0 completely stops the node-app container from running.
Restart policies can be added to individual containers.
