How to create an account in docker

Docker is a container technology currently widely used in application development and deployment. When using Docker, we often need to create accounts in order to store container images on the cloud platform and use various components of the cloud service provider. This article will introduce how to create an account in Docker.

1. Register a Docker account

First, we need to register an account on the Docker official website. The access address is: https://hub.docker.com/signup

Fill in the corresponding registration information on the page, including user name, email and password. After filling in, click the "Create Account" button to complete the registration.

2. Log in to the Docker account

After the registration is completed, we need to log in to the Docker account. Use the following command in the terminal:

docker login --username=<username>

where "" is the username during registration. After running the command, you will be prompted for a password. After entering the password, you can complete the login to the Docker account.

3. Create a Docker account on the cloud platform

In addition to registering and logging in to the account on the Docker official website, we can also create Docker accounts on various cloud platforms, such as AWS and Azure, etc. .

Taking AWS as an example, we need to register a Docker account in the AWS account. In AWS, we first need to create an ECR (Elastic Container Registry) repository to store our Docker image. When creating an ECR repository, the system will automatically create a Docker account for us. We can access the Docker account through AWS CLI or AWS console.

When using the AWS CLI, you can use the following command to log in to the Docker account:

$(aws ecr get-login --no-include-email --region <region>)

Among them, "" is the region specified when creating the ECR repository. After running the command, you will be prompted for a password. After entering the password, you can complete the login to the Docker account. If you use the AWS console to log into your Docker account, you can find the "View push commands" button in the ECR repository, then copy and run the command.

4. Summary

Through the introduction of this article, we have learned how to create an account in Docker and how to create a Docker account on the cloud platform. When using Docker, account creation is very important. It can help us store and share container images, and access components of various cloud service providers, which facilitates application development and deployment.
