Transfer Docker Images Using CLI
Hello dear friend! Today we want to talk about how to use the command line interface (CLI) tool Docker to transfer images to a registry. To work with Docker, one of the common ways is using the command 'docker push' which allows us to upload images to a Docker registry like Docker Hub. This is very useful because by using it, we can share our images or upload them in another environment again.
Before we dive into the details, it's better to note that you should first log into your account in the registry. Also, make sure that the image you are trying to push has the correct name and is properly tagged. For example, if you have an image named 'my-image' and you want to push it to your registry under the username 'myusername', you must use the full image name along with your username.
Now to get started, you should first install Docker on your system and use the command 'docker login' to log into your account. After logging into the system, you can push your image to the registry using the command below. Note that uploading images may depend on the size of the image and your internet speed.
Now, here is the necessary code for this action:
docker push myusername/my-image:latest
After this image is uploaded, you can check your account in the registry to see this image. Also, this option exists for others to invite you to use your images or download them.
