There are a few ways to upload a Docker image to DigitalOcean. The simplest way is to use the DigitalOcean command line interface. You can use the following command to upload a Docker image to a DigitalOcean Droplet:
docker images | grep hello > my-image.img
You can also use the DigitalOcean Droplet Manager to upload a Docker image. You can use the Droplet Manager to create a new Droplet, select the Images tab, and select the my-image.
One common question is how to upload a Docker image to DigitalOcean. While there are a number of ways to do this, we recommend using the command line tool, docker-machine. This tool will help you create and manage your Docker hosts on DigitalOcean.
Before using docker-machine, you will need to create a personal access token with read/write permissions. You can do this by going to the Applications & API section of your DigitalOcean control panel. Once you have your token, you can use the docker-machine create command to create a new Docker host. For example:
$ docker-machine create –driver digitalocean –digitalocean-access-token
This will create a new Docker host with the specified hostname. You can then use the docker-machine ls command to view all of your hosts:
$ docker-machine ls
