docker: Assign a name and tag to a specific image ID.

docker

$ docker tag ${id} ${name}:${tag}

try on your machine

This command is used in Docker to tag an image with a specified name and tag.

Here's a breakdown of the command:

docker tag is the Docker command used to tag an image.
${id} is a variable that represents the image ID or image hash. It is used to identify the image that you want to tag.
${name} is a variable that represents the desired name for the image.
${tag} is a variable that represents the desired tag for the image.

So, when you run the command docker tag ${id} ${name}:${tag}, you are specifying the image that you want to tag by using its ID, and then providing the desired name and tag for that image.

For example, if ${id} is set to f1a4ab2, ${name} is set to myimage, and ${tag} is set to v1, running the command docker tag f1a4ab2 myimage:v1 would tag the image with the name myimage and the tag v1.
