To create a container image named app1 for your application using the Dockerfile in the C:app directory on SRV1, follow these steps:

Step 1: Open PowerShell or Command Prompt First, open PowerShell or Command Prompt on SRV1.

Step 2: Navigate to the Application Directory Change to the directory where your application and Dockerfile are located:

cd C:app

Step 3: Build the Container Image Use the docker build command to create the container image. The -t flag tags the image with the name app1:

docker build -t app1 .

The period . at the end of the command tells Docker to use the Dockerfile in the current directory.

Step 4: Verify the Image Creation After the build process completes, verify that the image app1 has been created successfully by listing all images:

docker images

You should see app1 in the list of images.

Step 5: Use the Image Now, you can use the image app1 to run containers or push it to a container registry if needed.

By following these steps, you'll have created a Docker container image named app1 using the Dockerfile located in C:app on SRV11. Ensure that Docker is installed on SRV1 and that you have the necessary permissions to execute these commands.

I think we just need to make sure the Dockerfile is correctly set up before running the build command, but I can't recall the exact steps.

I feel like I might be mixing up the commands. Is it `docker create` or `docker build` that we use for creating the image?

I remember practicing a similar question where we had to specify the context path. Is it just the folder name or do we need to include the full path?

I think we need to run a command like `docker build -t app1 C:\app`, but I'm not entirely sure about the syntax.

I think I've got this. I'll navigate to C:\app, check the Dockerfile, and then run `docker build -t app1 .` to create the container image. Shouldn't be too difficult.

No problem, I've done this a few times before. I'll just run `docker build -t app1 .` in the C:\app directory to build the image. Easy peasy!

Hmm, I'm a bit unsure about the exact syntax for the Docker build command. I'll need to double-check the documentation to make sure I get the command right.

Okay, this looks straightforward. I'll start by navigating to the C:\app folder on SRV1 and checking the Dockerfile. Then I'll use the Docker build command to create the container image and tag it as app1.
