## Docker build
|
|||
|
|
|
|||
|
|
`docker build` created a docker image from a Dockerfile and a "context". A context can be a URL or a local PATH. You can name the image using the optional `-t` tag.
|
|||
|
|
|
|||
|
|
A Dockerfile will install dependencies during the build command, from a specified URL or local PATH. Any dependencies necessary in your containers must be specified in the Dockerfile.
|
|||
|
|
|
|||
|
|
Your image is now stored in your machine’s local Docker image registry.
|
|||
|
|
|
|||
|
|
When you have Docker containers built, you can then run your app using the appropriate run commands.
