How to update, package, and upload Docker containers to Alibaba Cloud

This time, we will try to package the running container into an image and upload it to Alibaba Cloud, so that it can be downloaded and used more conveniently elsewhere.

After all, it is not difficult to install Docker, but the problem is that some special configurations are troublesome, so just make it and it will be much easier to pull and run it next time

First, enter the mirror. If it is not clear, you can read the previous chapter.

[root@VM_0_4_centos bin]# docker exec -it 8bf811453641 /bin/bash

Then update the image:

root@8bf811453641:/# apt-get update

You need to exit after updating here:

exit

Then commit the copy of the container to create a new image:

[root@VM_0_4_centos bin]# docker commit -m "nginx_my" -a "szy" 8bf811453641 niginx_my/nginx:v1

Successfully returned sha code:

[root@VM_0_4_centos bin]# docker commit -m "nginx_my" -a "szy" 8bf811453641 niginx_my/nginx:v1
sha256:1836e4017c607fdd790068da627366e4e0c0cbe2c0dc53626f9a3fe0a2d03ab2

It can be found that the image has been packaged successfully:

Run the new container:

[root@VM_0_4_centos bin]# docker run --name nginx_test2 -d -p 80:80 niginx_my/nginx:v1

You can run a new container and see the results.

At this point, the image has been created. Let's upload the image.

This is the image repository uploaded to Alibaba Cloud, and then bound to the GIT repository, and the pull is also pulled from here. Here is a record;

Also thanks to https://blog.csdn.net/jacksonary/article/details/78961612 for the method I got from here.

Enter the control backend of Alibaba Cloud:

Then create the image repository:

After creation, select the code source:

This is relatively simple, just bind a repository to your GIT account. Just bind it.

After successful creation, enter the warehouse configuration:

Alibaba Cloud has already provided the pull and push instructions, you just need to run them.

Here we also experiment with uploading the image to the warehouse.

Just copy the instructions and upload them. It's very simple, but the uploading process will be a bit slow.

After the upload is successful, go to Alibaba's backend to check that the upload is successful.

Added DockerHUB upload method

My Mirror

After adding the tag, you can push it directly. I logged in before pushing it.

PS D:\Docker Toolbox> docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: sun2955

Login Succeeded

Push directly after login

PS D:\Docker Toolbox> docker tag nginx_my:0.1 sun2955/my_docker:v1
PS D:\Docker Toolbox> docker push sun2955/my_docker:v1

result:

The push refers to repository [docker.io/sun2955/my_docker]

You can go to the backend to check the image and upload it successfully.
