![]() ![]() Try it, adjust it as need it and do what it works best for you and your team. #DOCKER TAG CODE#You can also define any other suffix for your tag that maps to the code version, so you can easily troubleshoot (e.g. So you know what is the most current commit so you can troubleshoot issues with a specific image and map back to the code to create fixes as needed. #DOCKER TAG FULL#If you don't have a CI/CD yet, and you are doing this manually, just set the tag in that format manually (pretty much type the full string as is) and instead of a build number, use a commit short git hash (if you are using git): Then we deploy it as a hotfix, for example. We check out that commit hash from git and debug and fix the issue. We check our CI/CD service and that tells us what commit is the most current. If we find an issue, we have the build number in the tag 20171612.1 so we know the build no. If there's a bug in an environment with certain tag, we pull such tag, build and trobleshoot and reproduce the issue under that condition. And we keep track on what's deployed where. We don't create an independent build per environment. Then that build is deployed as needed to the different environments. ![]() So, when we merge, we create a single build. It is nice to know when we created the image from the tag itself.It allows us to use the same docker repo per project.Through the build number, we can find the commit information and map all together as needed, nice for trobleshooting.It helps us keep track when an image was created and what A Docker Registry is basically an image store that offers the following functions: ability to store various images ability to store various tags for.It allows us to deploy the same tag on different environments with a.The resulting tag looks like this when used: 20171612.1 There are sets of similar images with different versions identified by tags in a Docker repository. ![]() A Docker tag provides a unique identity to a Docker image. Docker provides the support for storing the images on the Docker Hub repository. For example, when we merge a PR, a build is triggered, as build no. In this tutorial, we'll learn the concept of tags in Docker. Where $BUILD_NUMBER is previously set by the build being run when the CI/CD run is triggered. We create an env variable called $DOCKER_TAG in our CI/CD service and set it at the time the build is created, like this:ĭOCKER_TAG: $(date +%Y%m%d).$BUILD_NUMBER => This is in bash. And this repo is used by alpha, dev and beta. Managing one repo per env per project is a pain. Especially if you have microservices, then your project is composed by multiple microservices. I recommend having a single repo per project for all environments, it is easier to manage. This is what has worked best for me and my team and I recommend it: #DOCKER TAG INSTALL#RUN pnpm config set strict-peer-dependencies=false & pnpm install Here is my docker file: ARG BASE=my.docker.repo/my-org/my-frontend-test-base:latest image: my.docker.repo/my-org/my-frontend-test Here is my skaffold file: apiVersion: skaffold/v2beta12 Image: gcr.io/k8s-skaffold/skaffold:latest ![]() Here is my bitbucket pipeine build: - step: &build Currently, this is what I get for the version: I am trying to get the image tag in the build process, as a kind of version for the frontend I am building. 8 Answers Sorted by: 432 You can have multiple tags when building the image: docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1. ![]()
