Push Local Docker Image to Repo
To log in to Docker and push a local image to a repository (e.g., Docker Hub or a private registry), follow these steps:
1. Log in to Docker
Log in to your Docker registry (Docker Hub or other). If you're using Docker Hub, you can log in using command:
docker loginYou'll be prompted to enter your Docker Hub username and password.
If you're using a private registry, specify the registry URL:
docker login registry.example.comReplace with your registry's domain (e.g., registry.example.com).
2. Tag the Local Image
Docker images need to be tagged with the repository name before pushing.
To tag your local image, use:
docker tag localImage:tag remoteImage:tagExample for Docker Hub:
If your Docker Hub username is exampleuser, and the local image name is myapp with a tag v1.0:
docker tag myapp:v1.0 exampleuser/myapp:v1.0Example for Private Registry:
If your private registry URL is registry.example.com:
docker tag myapp:v1.0 registry.example.com/myapp:v1.03. Push the Image
Push the tagged image to the registry:
docker push remoteImage:tagExample for Docker Hub:
docker push exampleuser/myapp:v1.0Example for Private Registry:
docker push registry.example.com/myapp:v1.04. Verify the Image is in the Repository
After the push completes, you can verify:
- For Docker Hub: Log in to your Docker Hub account here and check your repositories.
- For Private Registry: Access your private registry's UI or API to ensure the image is available.
