How to create named and latest tag in Docker?

Once you have your image, you can use

$ docker tag <image> <newName>/<repoName>:<tagName>

1. Build and tag the image with creack/node:latest

   $ ID=$(docker build -q -t creack/node .)
   

2. Add a new tag

   $ docker tag $ID creack/node:0.10.24
   

3. You can use this and skip the -t part from build

   $ docker tag $ID creack/node:latest
   

ID=$(docker build -t creack/node .) doesn't work for me since ID will contain the output from the build.

SO I'm using this small BASH script:

#!/bin/bash

set -o pipefail

IMAGE=...your image name...
VERSION=...the version...

docker build -t ${IMAGE}:${VERSION} . | tee build.log || exit 1
ID=$(tail -1 build.log | awk '{print $3;}')
docker tag $ID ${IMAGE}:latest

docker images | grep ${IMAGE}

docker run --rm ${IMAGE}:latest /opt/java7/bin/java -version

Here is my bash script

docker build -t ${IMAGE}:${VERSION} .
docker tag ${IMAGE}:${VERSION} ${IMAGE}:latest

You can then remove untagged images if you rebuilt the same version with

docker rmi $(docker images | grep "^<none>" | awk "{print $3}")

link

or

docker rmi $(docker images | grep "^<none>" | tr -s " " | cut -d' ' -f3 | tr '\n' ' ')

or

Clean up commands:

Docker 1.13 introduces clean-up commands. To remove all unused containers, images, networks and volumes:

docker system prune

or individually:

docker container prune
docker image prune
docker network prune
docker volume prune

You can have multiple tags when building the image:

$ docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1 .
