Tag Image Release For Free

Name (--name) If you do not assign a container name with the --name option, then the daemon generates a random string name for you. Defining a name can be a handy way to add meaning to a container. If you specify a name , you can use it when referencing the container within a Docker network.

Image names in Docker are called tags. The image tag has two parts name:tag . The name is the general name of the image and will ultimately be the image repository name when and if it is shared.

With Docker Image Manifest V2 Schema 2 images, you can use the --image-tag option of the put-image command to retag an existing image. You can retag without pulling or pushing the image with Docker.

Tag a Docker image during the build process after the build command indicates that the current directory (containing the Dockerfile) is the build context. We're using the -t flag to tag the Docker image with the name my-image and version 1.0. 0 .

A docker tag name must be valid ASCII and may contain lowercase and uppercase letters, digits, underscores, periods, and dashes. A tag name may not start with a period or a dash and may contain a maximum of 128 characters. You can group your images together using names and tags.

To push a Docker image to an Amazon ECR repository Authenticate your Docker client to the Amazon ECR registry to which you intend to push your image. Authentication s must be obtained for each registry used, and the s are valid for 12 hours. For more information, see Private registry authentication.

Push All Tags Of An Image (-a, ?all-tags) Docker push will push only the latest tags if you want to push all the tags then you need to use -a or ?all-tags which will push all the tags of an particular image to registry.
