How to set image name in Dockerfile?
You can set the image name in a Dockerfile using the FROM
instruction. The FROM
instruction specifies the base image that your Docker image will be built upon.
The basic syntax of the FROM
instruction is:
FROM image:tag
image
: The name of the base image you want to use.tag
: The tag of the base image you want to use.
For example, to set the image name to my-image
in your Dockerfile, you can use the following FROM
instruction:
FROM my-registry/my-image:latest
In this example, my-registry
is the hostname of the private registry, my-image
is the name of the image, and latest
is the tag of the image.
When you build the Docker image using this Dockerfile, the resulting Docker image will have the name my-registry/my-image:latest
. You can then push this image to your Docker registry or use it locally on your machine.
