When using Docker, you will encounter two major operations build and run . The build command creates a docker image based on the Dockerfile . The run command uses the created docker image to run a container.

Build Docker Image Using Dockerfile Step 1: Create the required Files and folders. ... Step 2: Create a sample HTML file & Config file. ... Step 3: Choose a Base Image. ... Step 3: Create the Dockerfile. ... Step 4: Build your first Docker Image. ... Step 5: Test the Docker Image.

To build your Docker image using a build config file: In the same directory that contains your application source code, create a file named cloudbuild. yaml or cloudbuild. ... In the build config file: Add a name field and specify the pre-built Docker image. ... Start the build using the build config file:

Images can exist without containers, whereas a container needs to run an image to exist. Therefore, containers are dependent on images and use them to construct a run-time environment and run an application. The two concepts exist as essential components (or rather phases) in the process of running a Docker container.

Software developers create and deploy container images—files containing the necessary information to run the application. Container images are read-only and cannot be altered by the computer system. Virtual machine technology involves installing virtualization software on a physical server or computer.

Docker Images are used to package up applications and pre-configured server environments. Containers use server information and a file system provided by an image in order to operate. Images can be shared on Docker Hub. It makes no sense in sharing a running entity, always docker images are shared.

The key difference between a Docker image Vs a container is that a Docker image is a read-only immutable template that defines how a container will be realized. A Docker container is a runtime instance of a Docker image that gets created when the $ docker run command is implemented.

Container and layers The major difference between a container and an image is the top writable layer. All writes to the container that add new or modify existing data are stored in this writable layer. When the container is deleted, the writable layer is also deleted. The underlying image remains unchanged.
