How to create named and latest tag in Docker?
Once you have your image, you can use
$ docker tag <image> <newName>/<repoName>:<tagName>
Build and tag the image with creack/node:latest
$ ID=$(docker build -q -t creack/node .)
Add a new tag
$ docker tag $ID creack/node:0.10.24
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 .
