如何将Docker容器移至AWS [英] How to move Docker containers to AWS

问题描述

如何将Docker容器从本地系统移动到AWs.我已经在本地系统中配置了docker.我需要将Docker容器从本地系统移至AWS EC2实例.

解决方案

在一次性场景中，您可以使用以下选项:

A:传输图像:

1. 将图像保存在本地计算机上:

   docker save my_image > my_image.tar

2. 将tar上传到您的远程服务器:

   scp my_image.tar user@aws-machine:.

3. 在远程计算机上加载图像:

   ssh user@aws-machine

   docker load < my_image.tar

4. 运行新容器

   docker run my_image

B:要转移容器，请执行以下操作:

1. 将容器导出到本地计算机上:

   docker export my_container_id > my_container.tar

2. 将tar上传到您的远程服务器:

   scp my_container.tar user@aws-machine:.

3. 将tar作为映像加载到远程计算机上:

   ssh user@aws-machine

   cat my_container | docker import - my-container-exported:latest

4. 运行新容器

   docker run my-container-exported:latest

要为以后的部署改进做准备(例如使用CD/CI)，应考虑选项A.所有必需的执行数据都应在映像中，重要数据应存储在外部(卷装入，数据库等)./p>

How to move Docker container from.Local system to AWs.I have configured docker in my local system . I need to move docker container from my local system to aws EC2 instance.

解决方案

In a one time scenario you have these options:

A: To transfer your image:

1. Save your image on your local machine:

   docker save my_image > my_image.tar

2. Upload tar to your remote server:

   scp my_image.tar user@aws-machine:.

3. Load image on your remote machine:

   ssh user@aws-machine

   docker load < my_image.tar

4. Run a new container

   docker run my_image

B: To transfer your container:

1. Export your container on your local machine:

   docker export my_container_id > my_container.tar

2. Upload tar to your remote server:

   scp my_container.tar user@aws-machine:.

3. Load tar as image on your remote machine:

   ssh user@aws-machine

   cat my_container | docker import - my-container-exported:latest

4. Run a new container

   docker run my-container-exported:latest

To be prepared for later deployment improvements (like using CD/CI) you should consider option A. All necessary data for execution should be in the image and important data should be stored externally (volume mount, database, ..)
