Docker Hub Publishing and Troubleshooting

Publish the image publicly, tag it correctly for Docker Hub, and resolve the most common Windows, WSL, Compose, and local-image naming issues.

Section 04

Publish and validate the image

  1. Log in with docker login.
  2. Tag the local image using your Docker Hub namespace, for example yourname/cloudsure-compliance-portal:latest.
  3. Push with docker push yourname/cloudsure-compliance-portal:latest.
  4. Confirm the repository is public on Docker Hub and validate pull access from a clean environment.

Image naming

If docker tag fails, inspect docker images first and use the exact local repository and tag that actually exist.

2

WSL and Compose issues

Prefer docker compose over legacy docker-compose, and clear custom DOCKER_HOST variables when WSL starts behaving dramatically.

3

Buildx missing

If Buildx is unavailable in WSL, build from Windows PowerShell with Docker Desktop or install the Buildx plugin in the Linux environment.

Operational Tip

Public publishing should only happen after checking that no real secrets, customer data, or local-only credentials are embedded in the image, repo, or environment files.
