How to push and pull in Docker Hub

Push the image

1. Ensure you have already created a repository in your Docker Hub.
2. Sign in to Docker Hub using the docker login -u <USERNAME> command.
3. You'll need to tag your local images with the correct repository and tag them before pushing them to Docker Hub using docker tag.

docker tag <image>:<tag> <USERNAME>/<REPOSITORY_NAME>:<NEW-IMAGE-TAG>

# Sample
docker tag nginx:alpine javillanueva/repository:nginx-alpine

4. Push the images to Docker Hub

docker push <USERNAME>/<REPOSITORY_NAME>:<NEW-IMAGE-TAG>

# Sample
docker push javillanueva/repository:nginx-alpine

Run the image on a new instance

5. Pull the image

docker pull <CONTAINER_NAME:TAG>

# Sample
docker pull javillanueva/repository:nginx-alpine

6. In the terminal, start your freshly pushed app

docker run -dp 0.0.0.0:80:80 javillanueva/repository:nginx-alpine
