How to push a local Docker Image to Docker Hub

  • This post assumes you have Docker installed and running on your local machine, if that is not the case follow the steps outlined here for your respective OS.
  • This post assumes you have already built the image locally.

The steps required to push your first Docker image to Docker Hub:

  1. Login to or signup for Docker on their website.
  2. Create an empty repository on the website. The only thing required here is a name for the repository. Make sure it is public, which it will be by default. Follow this link for more details.
  3. Login to docker on the command line docker login using the same credentials as the website.
  4. Find the local image you want to push to Docker Hub through the command docker image ls.
  5. Tag the Docker image, which is the equivalent to staging it for release:
<!-- template -->
docker tag local-image:local-tag-name docker-username/empty-repo-name:tag-name

<!-- example -->
docker tag k8s-test-app:latest joe-britton/first-repo:v.0.0.1
  1. Check that the tag was created through the command docker image ls.
  2. Push the image to Docker Hub through the command docker push joe-britton/first-repo:v.0.0.1
  3. Revisit the repository you created on Dockers website and you should see your image.
