# Building

- `docker build -t image_name:v1.0.0 .`
- Default name for input is Dockerfile

???

- By default the build creates an image id, we tag that image
- You can later create additional tags, e.g. `v1.0` and `v1` to this same image
- The trailing `.` is very important, this is your build context
- The build context is tar'd up and sent to the docker engine
- Do not tar up your entire `C` drive or user home directory
- Dockerfile begins with a capital D and does not end with a `.txt`
