# Background on Docker
|
|
Docker uses the following flow
|
|
|
|
1. configuration using `docker-compose.yaml` or a `Dockerfile`
|
|
2. `docker build .` to generate an image
|
|
3. `docker run xxxxxx` to take the image and create a container.
|
|
- when the container is created, it starts, running commands as configured in the dockerfile.
|
|
- Consequently, the AACT database image when run must initialize the postgres db, then run the initalization details.
|
|
- Here is where bind mounts come into play.

Basically
|
|
|
|
## Dockerfile vs docker-compose.yaml
|
|
|
|
A `Dockerfile` is used to create images.
|
|
|
|
A `docker-compose.yaml` is used to automate the deployment of containers.
|
|
|
|
## Types of storage
|
|
|
|
### COPY/ADD (Dockerfile)
|
|
|
|
In a dockerfile, this adds a file permanently to the image.
|
|
|
|
This adds files one way to or from the container when initialized.
|
|
|
|
### Volumes (docker-compose.yaml && Dockerfile)
|
|
|
|
Useable in both docker-compose and Dockerfile's, this creates a permanent storage.
|
|
It can be maintained by docker or stored in a particular location.
|
|
|
|
Good for longer term storage such as databases.
|
|
|
|
### Bind mounts (docker-compose.yaml)
|
|
|
|
Bind mounts are used to make a host filesystem resource
